In the workshop there are a number of hazards specific to welding or cutting and others, of a more general nature, which may also be present in the fabrication environment. Did You Know? There are many different types of potential hazards in welding and thermal cutting processes. Everyone involved should be aware of what these hazards are. Welding and cutting processes are safe, and the risks from the hazards can be reduced, if they are carried out correctly and with care. Potential hazards need to be identified, measured where appropriate, and assessed, and remedial measures put in place wherever necessary. Although Personal Protective Equipment, PPE, should not be issued as the primary method of reducing a hazard it should be issued to all personnel if beneficial. Employers and employees should be made fully aware of the dangers that can arise and take all reasonable care to ensure the health and safety of all.   Types of Hazards The hazards encountered in welding and cutting may be sub-divided into groups as follows: Electrical Magnetic Fields Compressed Gases Fuel Gases Inert Gases Cryogenic Gases Radiation Heat, Flames, Fire and Explosion Welding Fume and Gases Noise Material and Manual Handling Confined Spaces Thoriated Electodes Solvents ]

[ Home Medical Oxygen Therapy FAQ's Home Medical Oxygen Therapy FAQ: What is an oxygen concentrator? An oxygen concentrator is a device that filters out nitrogen from the air to deliver a higher concentration of oxygen. A concentrator is a reliable and cost-effective option for oxygen therapy. A stationary concentrator is used while at home and is powered by electricity. Portable, battery-powered oxygen concentrators are also available for use outside of the home. What is an oxygen cylinder? An oxygen cylinder is a metal walled container filled with very high pressure oxygen. A regulator is attached to the cylinder to reduce the pressure to a normal level. Oxygen cylinders do not require any power source and have a fixed volume of oxygen available in the container. How do I set-up to use the HMOT equipment? As part of our service offer, a trained home oxygen specialist can demonstrate how to set-up and operate the equipment safely. We will also provide you with a patient education booklet containing instructions and safety information. What do I do if my concentrator is not working? Call BOC on 0800 100 949, we will walk you through troubleshooting your concentrator and can help arrange a replacement if your concentrator develops a fault. What do I do if I urgently need a replacement oxygen cylinder? In most areas, BOC will deliver next day. Same day delivery is available on request subject to driver availability (a surcharge may apply). If you are in a situation where you need urgent medical assistance, call emergency services on 111 (in New Zealand). Do I need to clean or maintain my oxygen concentrator? Upon delivery, please read the instruction for use of equipment provided. Rental units are serviced every two-years but basic cleaning is required each fortnight. Ensure that the back of the concentrator is kept well ventilated. Please refer to our education booklet for further information. My oxygen concentrator uses electricity, can I claim a rebate? You may be entitled to a rebate for electricity used by medical equipment. Contact your electricity provider to discuss your eligibility and rebate rate. How can I transport my HMOT equipment? Transport your concentrator upright in a vehicle, secured by a seat belt or strap. Do not lay down an oxygen concentrator to transport it. To transport cylinders, store them upright and secure in the boot of your car. If you are using oxygen while driving, use a BOC carry bag to secure your cylinder behind the seat, keep windows slightly open for ventilation. For more detailed information, download our patient education booklet. Can I travel with HMOT? You can travel with HMOT, but you must advise your travel company and airline who will advise you of what is expected. You should also discuss your plans with your medical practitioner and with BOC so we can assist you. For more detailed information, download our patient education booklet. How do I pay for my home oxygen equipment? If you are a self-funded patient, you can pay for your HMOT equipment with direct debit. You will receive a statement which details the amount which will be direct debited from your selected bank account. If you are funded by a government or community package, please consult your funding body or package provider for further details. To safely receive HMOT, it is important to: →Use oxygen for therapy purposes only as directed by your physician →Keep out of reach of children →Do not allow untrained people to tamper with the equipment →Only use in well ventilated areas →Never smoke or use e-cigarettes (this includes anyone around you) near or around your oxygen equipment →Display the “home oxygen safety sign” at a visible entry point to your home Always ensure you read equipment instructions and for further assistance refer to our patient education booklet or contact BOC on 0800 100 949.     Contact Us General Enquiries, Hospital, Aged and Homecare 0800 100 949 or email healthcareNZ@boc.com Benefits of online ordering Buy from BOC at any time Exclusive online pricing - 10% off RRP on selected items Save time - it only takes 2 minutes on average to place an order online Learn more about online ordering ]

[ Brazing and soldering Processes Additive Manufacturing Analysis & Instrumentation Automation and Robotics Controlled & Modified Atmospheres Cutting, Joining & Heating Brazing and soldering Cutting Welding Freezing & Cooling GOLDOX® Brazing and soldering Maximising the efficiency of soldering and brazing with acetylene supply schemes and customised burner solutions Soldering/brazing is a joining process that involves using a filler material with a lower melting temperature than the components being joined. The molten filler material wets the surfaces of the heated components and is drawn into the narrow gap between them. The filler material always has a different chemical composition to that of the components being joined. A joining process is referred to as soldering if the filler material melts at 450°C or less. By contrast, the term brazing is used for melting temperatures above 450°C. Soldering/brazing allows operators to join similar and or different materials which would be difficult to bond with MIG welding. In addition, thin and heat-sensitive components can be joined. Maximising productivity An oxyfuel flame is used to heat components.  Using acetylene as the fuel gas greatly enhances the productivity of brazing/soldering, particularly when applied with best-in-class equipment. We offer a range of LINDOFLAMM® burners to optimise your soldering/brazing operations. They are designed to easily adapt to the heating power you require for the job. We support these burners with a range of complementary services, including advice and help on how to design and set up your gas supply system. Benefits: Rapid heating of components to be joined Exact component temperature for best results  Maximum productivity with acetylene as fuel gas  Wide burner selection adaptable to individual demands  Customised gas supply solutions  ]

[ Welding Processes Additive Manufacturing Analysis & Instrumentation Automation and Robotics Controlled & Modified Atmospheres Cutting, Joining & Heating Brazing and soldering Cutting Welding Freezing & Cooling GOLDOX® Welding Supporting all welding techniques with the full selection of welding, shielding and laser gases and mixtures along with reliable supply solutions plus robust, top-of-the-range welding equipment and apparatus Welding is an essential process in just about every industry. Various techniques are used to melt and fuse metals, steels and alloys. Arc welding uses the heat generated by an electric arc struck between an electrode and a workpiece to melt and fuse metal in the joint area. This is the most common fusion-based joining method used in industry today. However, laser welding is growing in popularity in the automotive industry in particular and in other sectors such as microelectronics and shipbuilding. This involves focusing a laser beam onto a workpiece by a set of mirrors. When the laser beam is moved relative to the workpiece, the energy of the focused laser beam melts the metal so that a joint is formed. In all welding processes, the shielding and process gases, their exact compositions and their purity levels play a key role in influencing weld quality and productivity. Full-Line Supplier We deliver the full range of welding, shielding and laser gases along with reliable supply solutions and robust equipment for all standard welding techniques. For more exacting needs, our welding engineers can advise on technically advanced laser welding solutions and bespoke gas mixtures to help you optimise your welding results so you can meet rising competitive, environmental and quality challenges.       For more information, please download the links below: NZ Basic Shielding Gas Brochure(PDF 18.0 MB) NZ Carbon and Low Alloy Steel Brochure(PDF 3.0 MB) NZ Non Ferrous Materials Shielding Gases Brochure(PDF 945.0 KB) NZ Stainless Steel Shielding Gases Brochure(PDF 3.0 MB) ]

[ Gaseous Fume Health & Safety Cylinder Information Acetylene Cylinder Safety Safety with Liquid Nitrogen LPG Cylinder Safety Sensitive Chemicals Declaration Welding & Cutting Hazards Cylinder Safety MMA Welding TIG Welding MIG Welding Heat Stress Confined Space Electrical Safety Noise Magnetic Fields Burns Light and Heat Radiation Ozone Eyes Metal Fume Fever Measurement of Fume Material Process Fume Particulate Fume Gaseous Fume Chromium in Fume Gaseous Fume Gaseous fume is process dependent, and doesn't originate from the welding consumable or parent plate. Processes most likely to give gaseous fume are those with an open arc, such as MIG, TIG and Plasma Cutting. Welding fume is an unavoidable by-product of welding. It consists of particulate fume, the part you can see and gaseous fume, which you cannot see, but can sometimes smell. All welding processes generate welding fume, the type and amount varying from process to process; MMA, MIG, FCAW and Plasma cutting tend to produce most, while TIG, Plasma welding, Laser welding and Submerged Arc give very little under normal circumstances, although TIG can give high levels of gaseous fume. What is Gaseous Fume? Gaseous fume consists of either one or more specific pollutant gases, mixed in the air around the welding area. As it is present at gaseous form it can easily enter the lungs. Whether the fume is likely to cause damage, depends largely on precisely what the gas, or gases are and on the concentration breathed in and the length of time of exposure to the specific pollutant(s). Sources of Gaseous Fume Gaseous fume may be formed by the action of a welding arc, or the radiation from it, on either the air surrounding the arc, some component within a flux or from coatings or contaminants on the component surfaces. Gaseous fumes are not emitted by the parent metal or the welding consumable. Exposure to Gaseous Fume Exposure to welding fume is affected by many factors, the main contributors include: - The welding or cutting process being used. - The alloy system(s) being welded. In most fabrication workshops, it is not always possible to control or change these factors because of other considerations such as the requirements of production. However, understanding the choices available and their effects can make it easier to make an informed judgement. Exposure Limits National health and safety organisations, such as ACGIH in America and HSE in Great Britain, issue, annually, lists of mandatory or recommended limits of exposure to hazardous substances for people at work. These limits represent maximum concentrations of welding fume and its component parts in air in breathing zones of workers. Effects of Excessive Exposure This section not intended as a medical text, but just as a reference. It is always recommended that professional medical or epidemiological opinion should be sought, if assistance is needed. The effects of exposure to fume may become apparent very quickly during welding, shortly afterwards, or at a much later date, and only for some hazards can indications be given. Some of the more common hazards encountered are outlined below:  Ozone Ozone is a very active and highly toxic gas, probably the most poisonous gas encountered in welding industry and must be treated with extreme caution. Oxides of Nitrogen These oxides, notably NO + NO2, react with moisture, possibly in the nose and throat, to form nitric and nitrous acids, and are extremely irritant and corrosive. Carbon Monoxide This has a high affinity for haemoglobin in the blood, and low concentrations can cause headache, shortage of breath. Dichloro-acetyl-chloride (DCAC), Phosgene If a welding arc is struck when vapours, from degreasing agents are in the immediate vicinity, an irritant gas, DCAC, will be produced. Hydrogen Chloride These acid vapours are extremely irritant to the upper respiratory tract. Control of Exposure Exposure to welding fume should be controlled to as low a level as practicably possible, but in any case kept below the current exposure limit. If an occupational hygiene assessment shows unacceptable concentrations, then additional controls will need to be put in place. Most health and safety bodies require that there should be engineering controls as a first option. ]

'Arc Eye' is one of the most common injuries suffered. Eye problems are probably the most common type of injury sustained by welders. The hazards to eyes in welding can be conveniently divided into three main groups: Non-ionising Radiation. Foreign Bodies. Fumes and Gases. These groups will be considered separately below, along with advice on protective measures which should be taken to avoid injury. Non-ionising Radiation All welding arcs produce radiation, but as the energy ranges in the arcs are limited only certain wavelengths are generated. This radiation is divided into three categories Ultraviolet (UV), Visible Light and Infrared (IR). Of these three UV is the most likely to cause injury because its effects are not noticed by any of the senses at the time of exposure and so the effects only become apparent sometime later. Arc welding and cutting processes produce all three forms of radiation UV, visible and IR, and present a greater hazard to the eyes than oxy-fuel gas flames which only produce visible and IR radiation. Ultraviolet Radiation Ultraviolet radiation is generated by arc welding, cutting and gouging processes but not by fuel gas processes. The most well known, and probable the most frequently suffered, effect from welding arcs is 'Arc eye' or 'welders flash' and this is caused by the effect of UV radiation on the outer eye. Visible Light Intense visible light may be generated by both electric arc and fuel gas processes. Prolonged exposure could lead to retinal burns, either photochemical or thermal, but it would be very difficult to work with such high levels of glare. In such situations the eye will naturally react to reduce exposure. Infrared Radiation The intense heat of IR from both electric arc and fuel gas processes can cause retinal burns and cataracts. Protection The best protection for avoiding radiation damage to the eyes is to NEVER look at a welding arc without proper eye protection, however tempting that may be. A wide range of filter glasses for welding helmets, screens and goggles are available for both gas and arc welding. One of the most common ways a welder can catch Arc Eye is by initiating the arc before having the welding helmet in place over the eyes. First Aid Should a welder or other worker get a "flash", then arc eye drops can be applied by medical staff before going home and this will prevent the onset of arc eye, although the eyes may still feel a bit sore. Similarly, if arc eye does come on while still at work, it can be treated by on-site medical staff, or the patient can be taken to hospital or a medical centre. Foreign Bodies Welders have a high incidence of eye injury due to foreign bodies, such as slag, spatter, sparks, dust and grit. Wire and chemicals can also present a hazard if mishandled. Slag Particles can enter the eye, if not protected, during de-slagging. As the slag is often removed while still hot, the injury can be compounded by adivitional corneal burns. Spatter Spatter from the welding process can cause quite nasty injuries because of its temperature and velocity. Grinding sparks, dust and grit Debris from the grinding disks can get into the eye of the operator, and other workers at some distance from the actual grinding operation. Chemicals Chemicals used before and after welding such as degreasing and cleaning fluids, acetone, dye penetrant, acidic or caustic etching solutions, can be splashed into unprotected eyes, causing nasty injuries. Protection Many welders do not wear safety glasses or other form of eye protection when not actually welding, even when carrying out high-risk activities like de-slagging and it is this lack of protection which increases the number of incidence of this type of accident. It is possible, when working in close proximity to other welders, that slag injury may be attributed to another welders activities, it is therefore a wise precaution to wear eye protection at all times in these circumstances. First Aid In many cases, a foreign body in the eye can be seen on examination, and removed with care by a suitably qualified person. The eye can also be washed with sterile saline solution and this will often move the particle. If the eye is painful or the particle cannot be removed easily medical advice must be sought. Any eye injury due to a foreign body should be examined and treated by suitably trained nurses, if they are present on site at the time of the accident. Fumes and Gases Particulate fumes and gases can irritate or damage the eye. It is known that conjunctivitis may be caused by dust or fume associated with welding. Contact Lenses and Welding Every year there are reports in newspapers that contact lenses have been fused to welders eyes by the arc, causing nasty injuries. ]

Modified Atmosphere Packaging (MAP) is the ideal way to achieve this. It is a natural method that is rapidly growing in popularity worldwide. In many cases, it can also complement alternative preservation methods. We have developed a range of application-specific packaging solutions under our MAPAX® brand. Synergizing the vast knowledge we have gained in food science, gas mixtures and packaging, MAPAX extends shelf life – the natural way. With MAPAX, you can: Increase sales by satisfying growing demand for fresh and naturally preserved products Extend shelf life without chemicals or freezing Increase  shelf life in the distribution chain by days or even weeks Retain taste, texture and appearance Enhance production and distribution efficiency by cutting costs. Success Through Partnership We work closely with food research institutes in many countries and have numerous food-processing customers worldwide. We also collaborate closely with the suppliers of packaging materials and machines to create the best atmosphere for each individual application. This is influenced by a number of factors, including the foodstuff and its properties, microbial activity, hygiene requirements, pre-packaging delay, temperature, permeability and other properties of the packaging material, the free gas volume within the package and the residual oxygen level. So, for instance, in the case of low fat products with a high moisture content, MAP focuses on inhibiting the growth of microorganisms in particular. However, in the case of products with a high fat content and low water activity, oxidation protection is the primary objective. The Technology MAPAX gas mixtures usually consist of the normal atmospheric gases such as carbon dioxide (CO2), nitrogen (N2) and oxygen (O2). Microbial growth can also be inhibited to a certain extent with the help of other gases such as nitrous oxide (N2O), argon (Ar) and hydrogen (H2). These gases can be applied individually or mixed according to specific ratios. CO2, for instance, is most effective in inhibiting microorganisms (such as mould and other common aerobic bacteria). It does this by dissolving into the food’s liquid and fat phase, thereby reducing its pH value. It also penetrates biological membranes, causing changes in permeability and function. As an inert gas, nitrogen is primarily used to replace oxygen in packaging, thereby preventing oxidation. Owing to its low solubility in water, nitrogen also helps to prevent package collapse by maintaining internal volume. Although the oxygen level should be as low as possible in most food packages, meat is an exception. Here oxygen helps to preserve the oxygenated form of myoglobin, which gives meat its red color. It is also valuable for fruit and vegetables as it lets them breathe. Tailored Packages We deliver a range of MAPAX solutions dedicated to the needs of the following industries: Dairy  Dry foods & bakery Fish & seafood Fruit & veg Meat Prepared & catered foods.

This causes the rate of gold leach to increase, leading to improved gold recovery, reduced cyanide consumption and importantly, improved profitability for your business. The GOLDOX® Process The gold dissolution process occurs in the presence of cyanide and oxygen. Often, the demand for oxygen in this reaction is not satisfied as there are a number of side reactions which compete for the available oxygen. In addition, the forward reaction is favoured by excess oxygen & cyanide. The BOC solution to oxygen starvation in gold leaching is GOLDOX®.  Features of GOLDOX® Process: Custom designed solution for each application An injection system to help raise dissolved oxygen levels A number of injections systems based on our patented dissolution processes are utilised to efficiently dissolve oxygen. The EDR® Dissolution System Designed to build on the GOLDOX® process, the unique EDR® dissolution system utilises various configurations to disperse pressurised oxygen into the slurry stream. This allows gold mines to achieve increased dissolved oxygen levels within the leach circuit. Benefits of EDR® devices: Optimised oxygen consumption  Increase control of cyanide consumption  Increased gold recovery  Reduced chemical risks  Reduced “in tank furniture” Low maintenance hardwearing dissolver        No moving parts and increased wear resistance compared to other technologies GOLDOX® 2.0 Panels The updated GOLDOX® panels are BOC’s new design of oxygen flow measurement and control panels. These panels have been optimised to be used with BOC’s suite of GOLDOX® oxygen dissolution devices. Building on the highly successful GOLDOX® panels, additional features have been added to provide more value for our customers.  New features include: Standardised flow range designed to be used with BOC dissolution devices  Automatic water flush incorporated into design to prevent dissolver blockages  Feedback of oxygen flow rates back to customer’s control system  Automatic and manual oxygen control modes for optimised oxygen addition  Redundancy built in, in case of component failure. GOLDOX® Lances As part of the GOLDOX® range of application technology, the GOLDOX® lances are designed to inject oxygen into a pre-conditioning CIL or CIP tank.  The design of the lance has a number of key benefits over other offerings in the market. This includes: The ability to remove a lance while the tank is online  The ability to water-flush the lance and nozzle arrangement to maintain peak operability  The ability to water-flush the sheath surrounding the lance to ensure the lance can be removed easily  Hardwearing high-grade alumina ceramic nozzles available in a range of styles  Optimised design to deliver oxygen to the right place in the tank  Seamlessly integrated with a GOLDOX® oxygen dosing panel The simplicity of the GOLDOX® nozzles ensures that oxygen will be delivered to the right place, in the most cost effective and efficient manner.

[ COVID-19 statement from John Evans, Managing Director, South Pacific About Corporate History Senior Leadership Team Supply and Procurement Corporate responsibility Ethics and Compliance Framework Health, Safety & Environment (HSE) Community Diversity & Inclusion News & Media Press Releases Case Studies Media Contact Competitions BOC @ Social Media Contact COVID-19 Statement Press Releases COVID-19 statement from John Evans, Managing Director, South Pacific In these unprecedented and uncertain times, BOC and Elgas wish to reassure our customers, our employees, and the communities in which we work that we are taking every measure to safeguard their safety and wellbeing while continuing to deliver our gases where and when they are most needed.   As essential services providers BOC and Elgas produce and deliver critical gases across the South Pacific region; from LPG for heating and cooking, to enabling gases that keep our power stations and water running, through to the very important medical oxygen and other medical gases.  Employee safety  Over the past six weeks we have taken a large number of measures to protect our employees and to ensure that our production sites remain open and operating to their full capacity. Some of the steps we have taken to reduce the risk for our employees include: Banning all non-essential air travel both domestically and internationally since 9 March Banning non-essential visitors to all sites across the South Pacific Implementing rigorous social distancing at all sites as well as other risk mitigation actions including: Working from home where possible The frequency of cleaning of lunchrooms and change-rooms has been increased, and checks are in place to make sure cleaning is occurring as expected Non-essential production employees have been instructed to work from an alternate location Shift overlap times have been removed to minimise employee contact  At sites where there is only one shift, the employees have been separated into two separate teams  Providing ongoing access to employee assistance providers to support the mental health of all employees and their families  Continuity of supply  We also want to reassure you about the continuity of supply and mitigations that BOC and Elgas have in place for all our gas products and services. We have a long standing and comprehensive Contingency and Disaster Recovery Plan for all our facilities in South Pacific.  Nearly all of BOC gases are produced locally using BOC owned plants and equipment. Across Australia and New Zealand BOC has eight-cylinder filling sites and nine Air Separation Units producing our gases as well as five sources of carbon dioxide. We manage every step in the production, packaging, logistics and distribution of gas from creation to delivery to our customers. This ensures a flexible supply chain that can quickly respond to changing customer requirements in any location. Due to our multiple production sites we have the unique ability to draw on our South Pacific network to ensure continuity if one or even multiple BOC production plants are temporarily closed.  Elgas has the most diverse LPG supply chain in Australia and New Zealand with access to local production sources via ship, road tanker or both. Elgas owns two major LPG storage facilities in Australia, the Elgas Cavern and the Elgas Dandenong Bulk Terminal, and is also a major shareholder in the Liquigas LPG Terminals across New Zealand. Aside from major terminals Elgas also has an extensive branch and depot network with over seventy LPG tanker and cylinder filling facilities across Australia and New Zealand.   Our unique distribution network provides robust delivery capabilities to support and supply products and services to BOC and Elgas customers during emergency situations such as this. We have the largest LPG transport fleet in Australia with over 120 LPG trailers, 130 rigid tankers and over 250 dedicated cylinder delivery vehicles – all staffed by local people. Medical gas supply and patient safety   Due to an anticipated increase in medical gas requirements as a result of the ongoing escalation of COVID-19, BOC has over the past six weeks taken proactive steps to assist us in meeting an increase in demand and to ensure patient safety including: Increased safety stock holdings of medical gases throughout our network of production sites and distribution points Additional stocks have been moved away from our major filling facilities to key strategic sites, near major population densities. This has been implemented to mitigate risks if one of our major filling sites is required to temporarily close. Implementation of dedicated ‘medical cylinder filling employees’ that work separately from the rest of the workforce  We have also taken steps to minimise the risk to the most vulnerable in our communities, our elderly. As a key supplier of medical gas and equipment to hospitals, medical facilities and aged care facilities we have now implemented dedicated aged care delivery trucks in our capital cities. By doing this we minimise the risk of transference to an aged care facility from other medical facilities.   Call centre and customer support  BOC and Elgas have locally based call centres in Australia and New Zealand, and we are already transitioning these centres to a remote working model to ensure ongoing customer support throughout this challenging time. Should you need support please contact: Australia: BOC on contact@boc.com or call Elgas on 131 161.  New Zealand: BOC on sales@boc.com or call Elgas on 0800 435 427 We will continue to monitor the situation and work with government, our customers and in particular our health and medical customers to ensure that we are able to continue providing our critical gases where and when they are needed.

[ Supply and Procurement About Corporate History Senior Leadership Team Supply and Procurement Corporate responsibility Ethics and Compliance Framework Health, Safety & Environment (HSE) Community Diversity & Inclusion News & Media Press Releases Case Studies Media Contact Competitions BOC @ Social Media Contact Supply and Procurement The objective of BOC’s Procurement Department is to identify the best suppliers in the marketplace and build strong relationships to provide year-on-year value for both businesses throughout the life of the contract. Our procurement process ensures goods and services are purchased in a way that is ethical, safe and environmentally conscious. Category Management Process Procurement at BOC operates under a Category Management (CM) Framework. CM is a comprehensive end-to-end engagement model for defining business needs and implementing the most suitable sourcing solution. A sequential and data-driven process is applied to ensure value for BOC and minimise the risk of non-compliance during post contract implementation. Category Sourcing BOC uses a range a of ‘go to market’ strategies to ensure competitive “Total Cost of Ownership” proposals are sought from the market. The “go to market” strategy is selected according to the requirements of the procurement need, and can include: Multi-supplier proposals Single source supplier proposals Request for information Formal request for tender Request for quotation Reverse auction BOC uses and therefore encourages the use of e-Procurement and highly values suppliers that offer and invest in such e-commerce solutions (e.g. Punch-out, catalogue systems, portals, etc). Ongoing Supplier Relations Through the use of ‘living’ contracts, both the supplier and BOC will have an understanding of each other’s objectives and will actively work to ensure that these are met and provide value. BOC will meet with its suppliers to provide open and honest feedback about the relationship and will use these meetings to drive performance. BOC has a philosophy of continuous improvement with its suppliers and works under Six Sigma methodologies to drive efficiency. Our objective is to reduce costs while improving value to BOC. The Procurement Department endeavours to treat all parties involved in the CM process fairly. Payment Terms To ensure timely payment, suppliers must submit accurate invoices to the Accounts Payable Department at BOC. The invoice must contain a Purchase Order number and there is a risk of non-payment if a purchase order has not been received. The invoice must also show the correct costs, quantities, description of the goods or services provided and must have completed delivery or properly performed the service required. If milestone payments are required, these must be negotiated and documented in a contract before any work is started. It is BOC policy to pay its suppliers thirty two (32) days from month end following receipt of an invoice. For example, if an invoice is submitted on the 16th of April, payment will be on the 1st June and an invoice submitted on the 30th April will also be paid on the 1st June. Supplier Endorsements Being a supplier of goods or services to BOC does not mean that the supplier is endorsed by BOC. If a supplier wishes to use any material that relates to BOC or The Linde Group then formal approval of that material must be sought from BOC. References may only be obtained from BOC if the supplier is in a contracted strategic relationship with BOC.

BOC will supply ammonia, which will be cracked and purified into pure hydrogen by the modular membrane technology unit developed by CSIRO. BOC engineers will also assist with compressing the hydrogen and storing it in special cylinder packs, then distributing it to customers on the Australian east coast for use in hydrogen fuel cell vehicles. General Manager Hydrogen Alex Dronoff says BOC is proud to be working with CSIRO researchers as they take a significant step forward in hydrogen technology, paving the way for a renewable hydrogen export market that could meet rising demand in emerging markets Europe, Japan and South Korea. “As the only global organisation with expertise and technology that covers the entire hydrogen supply chain, BOC and The Linde Group are committed to working with Australian researchers and industry to help advance the global transition towards clean hydrogen for mobility and energy. “We look forward to sharing our extensive experience with CSIRO as they enter the final development stages of the membrane technology device – providing advice on generation and storage, right through to transportation and refuelling of hydrogen-powered vehicles.”       CSIRO Energy Director Karl Rodrigues is excited by the growing global momentum to develop hydrogen energy systems, and the potential for a hydrogen export industry to benefit Australia. “We’re pleased to be partnering with industry – including BOC – and look forward to applying CSIRO innovation to facilitate the creation of new low emissions energy markets." Dronoff adds the CSIRO project is a vital technology breakthrough that complements much of the pioneering work that The Linde Group has been driving for decades. “With more than 150 fuelling stations built worldwide and over 1.5 million refuelling operations completed, Linde is continuously working on the expansion of hydrogen infrastructure. In August 2016 Linde launched BeeZero, the world’s first hydrogen-powered carsharing service – and is a joint partner of the Energie Park Mainz project that produces and stores renewable hydrogen for mobility applications generated by electrolysis through wind energy at a grid-relevant scale. “With this CSIRO technology, it will be easier and faster to replicate this success on an even larger scale. We are certainly excited by the significant role that Australia will play in making renewable hydrogen a fuel of the future.” For more information on the CSIRO project, click here .

[ Electrical Safety Health & Safety Cylinder Information Acetylene Cylinder Safety Safety with Liquid Nitrogen LPG Cylinder Safety Sensitive Chemicals Declaration Welding & Cutting Hazards Cylinder Safety MMA Welding TIG Welding MIG Welding Heat Stress Confined Space Electrical Safety Noise Magnetic Fields Burns Light and Heat Radiation Ozone Eyes Metal Fume Fever Measurement of Fume Material Process Fume Particulate Fume Gaseous Fume Chromium in Fume Electrical Safety Electric shock can kill and many electrical accidents are due to carelessness or complacency. Proper training and 'safe working practices' can markedly reduce the risks. The possibility of electric shock is one of the most serious risks encountered by a welder. Touching 'live' electrical components, including the electrode and the work piece, can result in serious a burn injury or, more seriously, electric shock. Electric shock can kill, either by direct action on the body, or by a resultant fall, if working at height. Most electrical accidents are avoidable and occur as a result of carelessness, lack of training, shoddy workmanship or due to faulty equipment. Welders must never become complacent about the hazards associated with electric arc welding and safe working practices should be followed at all times. What Is It? Electricity is a form of energy associated with the movement of electrons and protons in a conducting medium e.g. copper wire. The amount of electricity flowing is measured in 'amperes' and the pressure, or potential is measured in 'volts'.  Electricity will only flow when a circuit is completed and a potential difference exists in the circuit. Sources In welding there are many sources of electrical hazard over and above those encountered in everyday life. These include the welding power plant, auxiliary welding equipment such as cables, wire feed units, welding torches and electrode holders plus other associated tools and equipment such as grinders and electrode ovens etc. Serious injury can also result from contact with the welding circuit, and shocks from this source are probably the most frequently experienced by welders. Increased hazard situations If the welder is hot and perspiring, or if he or she is working in wet, damp, hot, humid or cramped conditions, the skin and clothing may become wet. Effects of Exposure The passage of an electric current through the body can cause severe injury and even death. The severity of the injury will depend on several factors including the actual current and voltage, the duration of current flow and how healthy the victim is. Limits and Legislation Welding equipment should be installed in accordance with international, national, or local standards and the manufacturer's instructions and tested to ensure it is correctly wired in, properly 'earthed', and safe to use. Control and Prevention Control of electrical hazards and prevention of electrical accidents should be paramount at all stages of a welding operation, from initial installation of the equipment, to its use and subsequent maintenance. Regulations, many industry codes of practice and safety guidance documents have been issued over the years regarding the safe use of electrical equipment and protective clothing to be worn when welding. Installation and Maintenance of Welding Equipment Only qualified personnel should install welding power sources. At this stage they should ensure that the mains supply isolator switch is correctly installed, has adequate power rating for the equipment and the socket plug connector is correctly wired. All inspections should be recorded, including an accurate record of findings. Use of Welding Equipment Before commencement of welding the welder should ascertain that all electrical connections are clean, tightly fixed and properly protected. Welders should also check that welding leads, work return leads and earth leads are capable of carrying the maximum operating current without overheating and are in good condition with no disruptions in the insulation and no exposed metal connectors. It is advisable that welders should not wear rings, bracelets, chains or metal watchstraps when welding as these items are good conductors of electricity and may result in serious burn injuries. General Advice There should be an easily accessible means of switching off the welding power source at the mains at the end of each work period or in the event of an emergency. Ancillary Equipment LVSD (low voltage safety devices) should be used whenever possible when MMA welding. These devices ensure that only low voltage is present at the electrode holder when no welding is taking place. First Aid Whatever the cause of the shock, never touch the casualty with bare hands until the casualty is no longer in contact with the electrical source or there is a risk of getting an electric shock yourself. If someone has had an electric shock and is still in contact with the source, do not touch the casualty until contact with the source has been broken. In all cases of electric shock, the casualty should be taken to hospital for treatment or assessed by a doctor. ]

[ Chromium in Fume Health & Safety Cylinder Information Acetylene Cylinder Safety Safety with Liquid Nitrogen LPG Cylinder Safety Sensitive Chemicals Declaration Welding & Cutting Hazards Cylinder Safety MMA Welding TIG Welding MIG Welding Heat Stress Confined Space Electrical Safety Noise Magnetic Fields Burns Light and Heat Radiation Ozone Eyes Metal Fume Fever Measurement of Fume Material Process Fume Particulate Fume Gaseous Fume Chromium in Fume Chromium in Fume Chromium can be present in fume in different forms. There are two main forms of chromium found in welding, trivalent, Cr3+, and hexavalent, Cr6+. Hexavalent chromium is considered the more hazardous of the two forms, and in welding fume it is a suspected human carcinogen. Chromium is an element present in the consumables and parent material of stainless steels, heat-resisting steels, some creep-resisting steels, some high nickel alloys, and armour plate. It may also be present in some consumables used for hardfacing. Chromium is also used as a coating for other materials, such as chrome plating, to give corrosion protection to steel, or to give a pleasing aesthetic appearance. Chromium, as chromate, may also be found as a constituent of some industrial paints. Welding or cutting materials containing chromium is likely to give chromium compounds in any particulate fume that is generated by the process. Whether it presents a significant hazard to health depends on the concentration and the duration of exposure. Chromium Formation in Welding When arc welding takes place on materials containing chromium, or by using consumables containing chromium, some of the chromium will be volatilised and escape from the protective gases in and around the arc. This metal vapour will be oxidised by the atmosphere to give particulate fume. Depending on the specific welding process being used chromium can be present in the fume in several different valency states, including trivalent, Cr3+; and hexavalent, Cr6. Effects of Exposure The major toxic effects of chromium in industry are concentrated on the nose, the skin and the lungs. The nose or, more specifically, the mucous membranes of the nasal septum, together with the skin of the hands and forearm, are the areas targeted by chromic acid and its salts. Control Measures When welding stainless steels using the MMA process there is a higher level of particulate fume generated than with MIG welding. However, an analysis of the fume generated would show that the MIG fume has a higher percentage of chromium present, typically 10 to 14%, this can be compared to about 6 to 8% for MMA. ]

[ Metal Fume Fever Health & Safety Cylinder Information Acetylene Cylinder Safety Safety with Liquid Nitrogen LPG Cylinder Safety Sensitive Chemicals Declaration Welding & Cutting Hazards Cylinder Safety MMA Welding TIG Welding MIG Welding Heat Stress Confined Space Electrical Safety Noise Magnetic Fields Burns Light and Heat Radiation Ozone Eyes Metal Fume Fever Measurement of Fume Material Process Fume Particulate Fume Gaseous Fume Chromium in Fume Metal Fume Fever Welding of certain materials can give rise to fume containing freshly formed metal oxide fume. If inhaled in sufficient concentration it can produce a reaction similar to a bout of flu. This is what is commonly known as Metal Fume Fever. Although it normally lasts no more than a day, it is possible to get an attack of fume fever more than once. However, there is no evidence to suggest that repeated bouts cause cumulative damage. The metal oxides usually associated with metal fume fever are those of zinc and copper, although others can have the same effects. In welding and cutting it is working with copper alloys, galvanised and some painted components that are most likely to this problem. Alternative names for metal fume fever include, 'Zinc Fume Fever', 'Brass Chills' or 'Brass Founders Ague'. These derive from the regular occurrence of fume fever in workers employed in brass foundries, where zinc, with its low boiling point (907°C), would boil-off when added to molten copper at 1083°C, forming zinc oxide in the air. Symptoms Metal Fume Fever is an acute, 'flu-like' attack brought on by exposure to freshly formed metal oxide fume. Symptoms are first experienced about 8 to 12 hours after inhalation of the metal oxide. Sufferer feel like they are going down with 'flu. Causes Fume Fever is caused by inhalation of freshly formed metal oxide fume. Any fresh metal oxide can cause it but it is most frequently associated with zinc, from welding brasses, galvanized iron and steel, other alloys containing zinc and in some instances zinc rich primers and paints. Control Measures The simplest way to avoid getting metal fume fever is to use a suitable fume extractor, correctly positioned, to take the metal oxide fume away from the welders' breathing zone. The most suitable kind of extractor is a high volume, low velocity unit, as this type can be used with all welding processes, including TIG and other gas-shielded processes, without disrupting the gas shield. ]

[ MIG Welding Health & Safety Cylinder Information Acetylene Cylinder Safety Safety with Liquid Nitrogen LPG Cylinder Safety Sensitive Chemicals Declaration Welding & Cutting Hazards Cylinder Safety MMA Welding TIG Welding MIG Welding Heat Stress Confined Space Electrical Safety Noise Magnetic Fields Burns Light and Heat Radiation Ozone Eyes Metal Fume Fever Measurement of Fume Material Process Fume Particulate Fume Gaseous Fume Chromium in Fume MIG Welding The main hazards from MIG welding are electrical, arc radiation, and welding fumes. Other hazards include inert gas, noise, heat, and fire. Welding fumes include both gaseous and particulate types. The MIG welding process is the most common welding process now used in manufacturing. It is capable of being used on a wide range of material types from common steels, to titanium. The MIG process produces a variety of hazards, not only to those carrying out the operation but also in many instances to others in the vicinity such as inspectors, labourers and even other welders. Some of the hazards encountered are specific to MIG welding while others are of a more general nature. Different hazards occur before welding commences, during welding and sometimes after welding has finished. When we look at the major hazards we will also consider when they may occur. Types of Hazards in MIG Welding The hazards encountered in MIG welding may be sub-divided into groups as follows: Electrical safety and Magnetic Fields Compressed gases, including inert gases Radiation Electrical Safety & Magnetic Fields Power sources for MIG welding and associated pieces of equipment, such as wire feed systems, welding guns, leads and connectors all require an electricity supply to operate. Power sources may operate from a three-phase supply, from industrial single-phase supply or even from a 13amp domestic power supply. It should always be remembered that electric shock can kill. Due to the potential severity of the hazard, the following is a guide on what to do before any MIG welding is started to reduce the risk of an electrical accident: - Only qualified personnel should be allowed to install MIG equipment. - The equipment must be tested to ensure it is operating correctly and safely before being put into service. During welding the possibility of electric shock is one of the most serious risks encountered by a welder. Most electrical accidents occur as a result of carelessness, poor workmanship or due to faulty equipment. The following points provide a guide to what to reduce the risks: - Welders should not remove panels from a welding power source if it stops working correctly. Touching a lead inside the welding set with the power still on can result in a serious primary voltage shock. - Never ignore a blown fuse, it is a warning that something is wrong. The following practice will help prevent electrical accidents: - When welding is temporarily interrupted welding guns should be placed where they are safe and the gun switch cannot be activated accidentally. Compressed Gases Shielding gases used for MIG welding may be 100% inert, 100% active, or a mixture of inert and active gases. Whatever their composition, the main risk to welders and others from the shielding gas is that of asphyxiation. Inert gases are not toxic, but will not support life. The following should be considered to ensure safety while this is being carried out: - Always use the correct regulator for the gas and ensure that it suitable for the pressure contained in the cylinder. - Never modify a regulator for use with another product. Radiation MIG welding produces electromagnetic radiation over a wide range of wavelengths. These wavelengths cover three distinct types of 'non-ionizing' radiation, namely, Ultraviolet (UV), Visible Light and Infrared (IR). MIG welding however, does not produce ionizing radiation. Some points to bear in mind are: - Radiation is only generated while the arc is generated and the amount emitted generally increases as the welding current increases. - Burns can be avoided by wearing proper protective clothing and ensuring no areas of skin are left exposed. Heat Sources of heat include welded components, the electrode holder and hot or discarded electrodes, and any of these can cause burns to the skin. A hot environment can cause the body to overheat, and this is known as Heat Stress. However those working in welding shops can reduce the risk by adhering to the following recommendation: Always assume all metal objects in a welding shop are hot. Welding Fume and Gases Welding fume is an unavoidable by-product of MIG welding, although fume generation from the process is generally low. However, the welder should still be aware of what fume is likely to be generated while welding is taking place and the potential hazards of exposure to the welding fume. Particulate Fume Particulate fume is mostly formed from vapourisation of the welding consumable. The following general statements are a rough indication of what the constituents of the particulate fume are likely to be: - Fume from MIG welding aluminium is mostly aluminium oxide. - Fume from MIG welding steel is mainly iron oxide plus a small amount of manganese oxide and other alloying elements. Gaseous Fume Welding processes with open arcs, such as MIG, are likely to promote the formation of gaseous fume as a result of the action of ultraviolet light and heat on atmospheric oxygen and nitrogen. The main factor controlling its production are: - Argon-rich shielding gases are more likely to promote ozone production than are helium-rich shielding gases or 100% carbon dioxide. Exposure to Fume Whilst all components of welding fume may present a risk to health, given a high enough concentration, some present a greater hazard than do others. The potential effect of exposure to welding fume depends upon: - The composition of the fume. - The volume of fume produced. Noise The MIG welding processes, like all others, generates noise. Some power sources, notably some pulsed MIG and synergic MIG sets, are noisier than others and some additionally generate high frequency noise that can affect hearing. Manual Handling Back injuries are one of the most common industrial injuries suffered by workers. Welding consumables may be heavy or awkward to lift. Confined Spaces Any of the hazards associated with MIG welding will be exacerbated when welding is carried out in a confined space. Solvents Flammable solvents may have been used to clean components prior to welding and may still be present around the welding area, presenting a fire or explosion hazard. The welder should allow all traces of any solvents to disappear from component surfaces and ensure no containers of solvent are in close proximity before welding starts. Workshop Safety General workshop safety is really a matter of common sense and good housekeeping and the following actions may be used to avoid accidents: - Maintain a tidy work area, especially free from trip hazards. - Keep walkways clear and free from welding cables, spare material, consumables, etc. Practical Considerations The advice given above is general in nature but forms a good overview of the potential hazards associated with the process. There are, however, things that can be done to help reduce the possibility of problems occurring in the workplace: Training There is a considerable amount of misinformation in the fabrication industry about the health hazards associated with welding. There is also a lack of understanding among welders as the how they can influence the type and severity of hazard. The main cause for this is often poor training and some welders appear to be unwilling to operate at welding conditions that will keep fume production to a minimum. Routine Maintenance, Safety Audit and Equipment Inspections Simple routine maintenance and a formalised system of safety audits on welding equipment has been shown to help reduce the number of safety related incidents within the industry. Personal Protective Equipment Welders should ensure that they wear appropriate clothing for the operation they are carrying out. Flame-retardant boiler suits, gloves or gauntlets, safety shoes, leather aprons, etc, should be in good condition and as free from oil, grease and moisture as is physically possible as these can reduce the effectiveness of the safety equipment. ]

[ Home Medical Oxygen Therapy What is home medical oxygen therapy Home medical oxygen therapy (HMOT) is a treatment that is used to increase blood oxygen saturation and is prescribed for patients with a range of respiratory conditions to use in their own home or living environment. How does HMOT work? Organs need oxygen in order to function correctly – chronic obstructive pulmonary disease (COPD) and other lung conditions may result in reduced blood oxygenation. Home oxygen therapy provides patients with high concentration oxygen, ensuring vital organs are receiving the oxygen required for healthy function. How do I know if I need HMOT? Your doctor will advise if you need supplemental oxygen after testing either arterial blood gas or pulse oximetry. Your doctor will specify the flow rate, hours of the day that oxygen therapy is required and often the type of equipment necessary to best suit your needs. Your doctor will provide you with a script or letter with these details. HMOT with BOC BOC has been delivering HMOT services for over 20 years, providing home medical oxygen to patients in New Zealand. BOC offers a range of oxygen concentrators, oxygen cylinders and other equipment. If you receive HMOT through a District Health Board (DHB), the DHB will manage your equipment setup. If you are a private patient, BOC will help you set up your equipment.

[ MMA Welding Health & Safety Cylinder Information Acetylene Cylinder Safety Safety with Liquid Nitrogen LPG Cylinder Safety Sensitive Chemicals Declaration Welding & Cutting Hazards Cylinder Safety MMA Welding TIG Welding MIG Welding Heat Stress Confined Space Electrical Safety Noise Magnetic Fields Burns Light and Heat Radiation Ozone Eyes Metal Fume Fever Measurement of Fume Material Process Fume Particulate Fume Gaseous Fume Chromium in Fume MMA Welding There are many different types of safety hazards produced by MMA welding. The main risks are from electric shock, welding fume and radiation. Hazards may be present before, during or after welding. The MMA process produces a variety of hazards, not only to those carrying out the operation but also in many instances to others in the vicinity such as inspectors, labourers and even other welders. Some of the hazards encountered are specific to MMA welding while others are of a more general nature. Different hazards occur before welding commences, during welding and sometimes after welding has finished. When we look at the major hazards we will also consider at what stage they may occur. All the potential hazards need to be identified, measured where appropriate, assessed, and remedial or preventative measures put in place wherever necessary. It should also be remembered that different hazards may have the same effect on the body and so interactions between hazards should also be considered. Types of Hazards in MMA Welding The hazards encountered in MMA welding may be sub-divided into groups as follows: Electrical and Magnetic Fields Radiation Heat, flames, fire and explosion Welding fumes Electrical Safety & Magnetic Fields Power sources for MMA welding and associated pieces of equipment, such as electrode holders, leads and connectors all require electricity to operate. Power sources may be AC or DC, operate from a three-phase supply, from industrial single-phase supply or even from a domestic power supply, and are often designed to operate with high open circuit voltages (OCV). Primary and secondary connections should be completed by competent persons. It should always be remembered that electric shock can kill. Due to the potential severity of the hazard, the following is a guide on what to do before any MMA welding is started to reduce the risk of an electrical accident: - Only qualified personnel should be allowed to install MMA equipment. Whoever does install  the equipment must ensure that it complies with national standards, any local regulations, the manufacturer's instructions and workpiece 'earthing' requirements. During welding the possibility of electric shock is one of the most serious risks encountered by a welder. Most electrical accidents occur as a result of carelessness, poor workmanship or due to faulty equipment. The following points provide a guide on what to do to reduce the risks: - Welders should not remove panels from a welding power source if it stops working correctly. Touching a lead inside the welding set with the power still on can result in a serious primary voltage shock. - Never ignore a blown fuse, it is a warning that something is wrong. The following practices will help prevent electrical accidents: - When welding is temporarily interrupted electrode holders should be placed where they are safe and the electrode cannot accidentally arc. It is safer if the electrode is removed from the holder. - If welding is to be stopped for any length of time the welding set should be switched off. Radiation Arc welding produces electromagnetic radiation over a wide range of wavelengths. These wavelengths cover three distinct types of 'non-ionizing' radiation, namely, Ultraviolet (UV), Visible Light and Infrared (IR). MMA welding does not produce ionizing radiation. Burns to the skin and eyes due to exposure to arc radiation may not become apparent until some time after welding has ceased. Some points to bear in mind are: - Radiation is only generated while the arc is generated and the amount emitted generally increases as the welding current increases. - Burns can be avoided by wearing proper protective clothing and ensuring no areas of skin are left exposed. Heat Sources of heat include welded components, the electrode holder and hot or discarded electrodes, and any of these can cause burns to the skin. A hot environment can cause the body to overheat, and this is known as Heat Stress. However those working in welding shops can reduce the risk by adhering to the following recommendation: Always assume all metal objects in a welding shop are hot. Welding Fume and Gases Welding fume is an unavoidable by-product of MMA welding. The welder should be aware of what fume is likely to be generated while welding is taking place and the potential hazards of exposure to the welding fume. Fume consists of particulate fume, the part you can see, and gaseous fume, the part you cannot see, but can sometimes smell. Particulate Fume Particulate fume is mostly formed from vapourisation of the welding consumable. Fume from MMA welding aluminium is mostly aluminium oxide, chlorides and fluorides. Gaseous Fume With MMA welding there is very little gaseous fume produced under normal circumstances. Exposure to Fume Whilst all components of welding fume may present a risk to health, given a high enough concentration, some present a greater hazard than do others. The potential effect of exposure to welding fume depends upon: - The composition of the fume. - The volume of fume produced. Noise The MMA welding processes, like all others, generates noise. Some power sources emit more than others and some additionally may generate higher frequency noise that can affect hearing. Manual Handling Back injuries are one of the most common industrial injuries suffered by workers. Cartons, packets, or tins of electrodes stored high off the ground can create a 'falling' hazard. Confined Spaces Any of the hazards associated with MMA welding will be exacerbated when welding is carried out in a confined space. Workshop Safety General workshop safety is really a matter of common sense and good housekeeping and the following actions may be used to avoid accidents: - Maintain a tidy work area, especially free from trip hazards. - Keep walkways clear and free from welding cables, spare material, consumables, etc. Practical Considerations The advice given above is general in nature but forms a good overview of the potential hazards associated with the process. There are, however, things that can be done to help reduce the possibility of problems occurring in the workplace: Training There is a considerable amount of misinformation in the fabrication industry about the health hazards associated with welding. There is also a lack of understanding among welders as the how they can influence the type and severity of hazard. The main cause for this is often poor training and some welders appear to be unwilling to operate at welding conditions that will keep fume production to a minimum. Routine Maintenance, Safety Audit and Equipment Inspections Simple routine maintenance and a formalised system of safety audits on welding equipment has been shown to help reduce the number of safety related incidents within the industry. Personal Protective Equipment Welders should ensure that they wear appropriate clothing for the operation they are carrying out. Flame-retardant boiler suits, gloves or gauntlets, safety shoes, leather aprons, etc, should be in good condition and as free from oil, grease and moisture as is physically possible as these can reduce the effectiveness of the safety equipment. ]

As such, the normal hazards of welding are intensified when carried out in confined spaces. Asphyxiation is the main danger and the most common cause of death in confined spaces. A formal 'safe system of work' should be followed at all times. Many of the everyday hazards encountered in welding can be exacerbated if the work is being carried out in a confined space. A significant number of deaths involving people working in confined spaces occur each year, with asphyxiation being a major cause of those deaths, so extra vigilance is needed. One dictionary definition of 'confined' is 'imprisoned', and a confined space is one where the means of entry and exit are restricted. The space itself does not have to be small and cramped, but if it is then there is likely to be restricted ventilation, which can allow the build up of a hazardous atmosphere. Then it may be described as 'confined'. An example of confined spaces would be a storage tank, it may also contain, or have contained, toxic, flammable or hazardous substance, vapour or gas. So it is clear that working in such spaces requires a greater awareness of potential hazards and safe working practices than normal. Welders working in enclosed spaces must be properly trained, equipped and supervised. Additional protective and monitoring equipment over and above that normally necessary may be required when welding in a confined space. It is also recommended that a formal 'safe system of work' should be followed at all times. Major Hazards When welding in confined spaces some hazards become more intense and require more attention. These are ventilation and the maintenance of a safe working atmosphere, the risk of falls or entrapment, the risk of electric shock, the risk of fire or explosion, and radiation or heat problems. Ventilation/Fume Maintaining an atmosphere that is fit to breathe inside a confined space can be difficult as fumes and gases may build up and displace the oxygen present. This presents one of the most insidious hazards, since lack of oxygen, or the presence of a toxic, explosive, flammable or inert gas cannot be seen and more often than not cannot be smelled either. The danger is that an operator could unwittingly enter what seems to be a perfectly normal area and quickly find out that it is not, and by then it may be too late! Falls and Entrapment Due to the difficult and restricted entry and exit it is easy for someone to trip, stumble or fall whilst getting into or out of the space. Merely slipping on a wet or greasy floor inside a confined space can be serious, the casualty could become trapped in a position where his breathing may be restricted and he may suffocate. Electrical Particular attention should be paid to electrical safety when welding in a vessel or tank. The metal of the enclosure will become part of the welding circuit and you may be standing on part of the vessel that is electrically 'hot' and any metal you touch may also be part of the welding circuit. Radiation and Heat When welding inside vessels made of reflective metal or alloy, for example, aluminium or stainless steel, the problems presented by glare and UV radiation can intensify. The risk of getting arc burns to the skin or 'arc eye' or arc flash due to reflected radiation increases. Fire and Explosion There is a great danger that flammable gas and vapour may collect in a confined space, and these may ignite when welding or cutting takes place leading to an explosion. Fuel gas processes also increase the risk of fire and explosion particularly if leaking equipment is left in the confined space, allowing a build-up of fuel gases or oxygen. Any heat from welding or cutting, or just an electric spark, can then result in a fire or explosion. Precautions Ventilation/Fume It is essential that the atmosphere in any confined space is tested and passed fit before entry. An atmosphere fit for working in is one that is breathable (i.e. has about 21% oxygen) and there are no toxic, flammable, or explosive gases or vapours present. It is also important that there is no enrichment of the atmosphere with inert gases or oxygen. Evaluation of confined space atmospheres must include measurements for oxygen plus any other relevant gas. Falls and Entrapment Precautions to avoid trips and falls are basically common sense, vigilance and good housekeeping. Keep floors inside the space as dry, grease-free and free from obstructions as far as possible. Electrical To reduce the risk of electric shock, it is recommended to locate electric welding power sources outside and ensure all cables entering the area are properly insulated. Welders and others should make sure that they are insulated from the workpiece and grounded by dry insulation. Radiation and Heat Wherever possible use radiation and heat shields to prevent burns. Take plenty of replacement fluid when working for lengthy periods in hot conditions to avoid dehydration and possible heat exhaustion. Fire and Explosion When using fuel gas processes extra care should be taken to ensure that the equipment is not leaking, as this can result in build-up of gas and possible explosion. Oxygen should never be used to enrich the atmosphere in a confined space. It is a severe fire and explosion hazard. Safe Working Systems All those engaged in working in confined spaces should work to a formal, written, 'safe system of work' that defines precisely what happens before, during and after each job, and assigns responsibilities for all actions. A safe system of work should require assessment, measurement and control of risk at all stages. A preliminary assessment of the risks involved in carrying out the work would include such things as: - What was the area or vessel used for? - Could there be any chemical or physical hazards present that may require cleaning or purging? - What ventilation might be required? All personnel should be trained for the conditions they will be required to work under and this training must include an appreciation of all the hazards of working in confined spaces. No welder should be expected to work alone. Regulations There may be regulations regarding work in confined spaces embodied in law in the country in which you are working. If not, the health and safety authorities will have available written approved codes of practice or recommendations for safe working in these conditions. Such documentation should be sought and adhered to whenever possible to ensure you are complying with the law or working in an approved and safe manner. Special regulations may apply to purging of tanks, which have previously contained flammable or explosive materials. ]
