2 OUR MISSON IS TO PROTECT YOU Welding and welding sites present numerous hazards to health and safety, both for welders and for people in the vicinity. WELDING FUMES/RESPIRATORY HAZARDS The fumes are composed of very small, solid metal oxide particles that form during the welding process. The majority of the fumes (90-95%) come from the filler metal used, so the chemical content of the welding fumes is the same as that of the filler metal. Short-term effects of welding fumes The short-term effects of overexposure to welding fumes include irritation of the eyes, nose and throat, coughing, shortness of breath, bronchitis, increased risk of infection of the respiratory tract, fluid in the lungs and a flu-like illness often called metal fume fever. Long-term effects of welding fumes Welders health is affected in the long term in that they face a 30 to 40 percent increased risk of lung cancer. The exact reason for this is still under careful study worldwide. It may be due to the fact that many welders are heavy smokers and are often exposed to asbestos and/or welding fumes. The most likely carcinogenic components of welding fumes are hexavalent chromium and nickel. Exposure to manganese often results in damage to the central nervous system. The link between this nerve damage and welding fumes is currently under investigation. RECOMMENDATION Always use respiratory protection equipment suited to the type of welding you are carrying out. SPARKS AND SPLASHES Welding normally gives rise to atomised sparks and splashes. If the shielding gas does not have a suffi ciently high argon content, larger quantities of sparks and splashes arise and may even be in the form of drops. If drops, sparks or splashes hit the welder, e.g. during welding from underneath or if the welder is lying down, they may cause burns. RECOMMENDATION Use all-over protective clothing if there is a risk of being hit by large quantities of drops, sparks or splashes.

3 UV RADIATION Overexposure to UV radiation affects health, and welders are the largest occupational group exposed to UV radiation. Short-term effects of UV radiation Skin sunburn. Damage accumulates during the day and does not become visible until a few hours later. Welders flash, also known as arc-eye and snowblindness. This is a painful irritation of the cornea and the conjunctiva (the membrane connecting the eyeball with the inner eyelid). It feels like sand in the eye, and can be felt at the slightest touch. UVB is the principal cause of sunburn of the eye. The eye is more sensitive than the skin to UV radiation because it lacks the skin s outer layer and protective pigment. Symptoms appear from six to 24 hours after exposure and usually disappear within the following 48 hours. Long-term effects Damage to the retina may ultimately result in loss of vision. This may be caused by UV radiation in people who have had an eye lens surgically removed, for example as a result of a cataract. Such damage to the retina can be prevented by the use of UV-absorbing glasses or the implantation of UV-absorbing lenses. In the normal eye, the retina is protected from UV injury because the vitreous body filters out UV radiation. Recent research indicates that exposure to UV radiation can adversely affect the immune system. RECOMMENDATION Always use a welding filter suited to the type of welding being carried out. No permanent damage to the eyes results, unless the exposure has been severe. RESPIRATORY PROTECTION IN THE HIGHEST PROTECTION CLASS Respiratory protection is divided into two main groups: Filter protection Breathing air passes through a filter which purifies it. (May only be used with normal oxygen content) Breathing apparatus Breathing apparatus supplied with compressed air. Portable respiratory devices HOW GOOD IS MY RESPIRATORY PROTECTION? To state the protective effect of the respiratory protection, you can calculate the protection factor on the basis of measurements. If the concentration of a substance inside the mask is a twentieth of what it is outside the mask, the protection factor of the respiratory protection is 20. If you are welding in a confined or poorly ventilated space, good filter protection is not sufficient. You also need respiratory protection supplied with compressed air in order not to put your health at risk. Mediumheavy work requires an average air consumption of l/min. 1,000 particles/cm 3 (outside respiratory protection) 50 particles/cm 3 (inside respiratory protection) = Protection factor 20 ASSIGNED PROTECTION FACTOR - APF The Assigned Protection Factor (APF) is based on measurements made in actual workplaces on actual people at work. This factor is somewhat lower than the Nominal Protection Factor, but the APF corresponds more closely to reality, as it is measured in actual working situations. NOMINAL PROTECTION FACTOR The Nominal Protection Factor (NPF) is based on measurements made in the laboratory.

8 DO YOU KNOW WHAT YOU ARE BREATHING? Depending on which environments the respiratory protection is to be used in, you choose a filter to suit your needs. SR 221 PRE FILTER SR 336 STEEL NET DISC SR 221 must be used together with particle, gas and combination filters at all times. The pre-filter protects the main filter against premature clogging by larger particles. The pre-filter holder fixes the filter in place and protects it against handling damage. SR 336, consists of a disc punched out of stainless steel mesh. The disc is fitted at the bottom of the pre-filter holder of the mask and protects the filters against sparks and spatter that occurs during welding, flame cutting, grinding and similar work. PARTICLE FILTER SR 710 P3 R PARTICLE FILTER is a mechanical particle filter with extremely low breathing resistance. SR 510 offers protection against all types of particles (dust, smoke, mist, spray, asbestos), as well as bacteria, viruses and radioactive fallout. Filtering efficiency more than %. SR 510 is used for all protective filters in Sundström Safety s programme. If gas/vapour and particles occur simultaneous-ly, a particle filter is combined with a suitable gas filter. SR 710 particle filter P3 R is a mechanical particle filter of class P3 R with an extremely high efficiency (> %) and an active area of 13 dm 2. The filter offers protection against all types of particles, both solids and liquids. SR 710 cannot be combined with gas filters. SR 218 A2 GAS FILTER SR 518 A2 GAS FILTER SR 218 A2 offer protection against organic compounds with a boiling point above 65ºC. SR 518 gas filter A2 is a filter for protection against organic compounds with a boiling point above +65 C, i.e. most solvents. Class 2 means high capacity and thus a long operating time. Gas filters for fan SR 500 must be used in combination with particle filter at all times. SR 315 ABE1 GAS FILTER SR 515 ABE1 GAS FILTER SR 315 ABE1 offer protection against organic compounds with a boiling point above 65º, inorganic compounds and acidic gases/vapours. SR 515 ABE1 protects against organic compounds with a boiling point above 65 C, inorganic and acid gases/vapours. SR 500 och SR 500 EX fan units gas filters must always be used in combination with particle filter.
