MIG WELD Material Safety Data Sheet for Copper Welding Alloys

Revision 02-2002

1. PRODUCT/CONSUMABLES a. MIG WELD copper alloys are used for MIG and TIG welding or MIG and TIG brazing of copper, bronze, copper alloys and steel, conforming to the international standard. 2. PRODUCER/SUPPLIER a. MIG WELD GmbH Deutschland, Wattstraße 2, D-94405 Landau a. d. Isar, Germany. Tel.: +49 (0) 9951/601230, Fax: +49 (0)9951/601239 b. Emergency Telefone: +49 (0) 9951/601230 3. INFORMATION AND COMPOSITION OF THE PRODUCTS a. Copper alloys welding wire or rods b. Substance compositions see appendix 1 4. HAZARDS IDENTIFICATIONS a. Not welded: The products are dense materials and even small boxes are relatively heavy. They should therefore not be left in a position where physical injury or accidents could be caused. Care should be taken in lifting and handling. b. Not welded: Skin contact does not normally present a hazard, though it is always possible that occasionally individuals may be found who are allergic to substances usually regarded as inert. However, we do not know of any case in which welding consumables have been identified as the cause of allergic response. c. Hazards during welding: The recommended limit on the concentration of welding fume (or other atmospheric contaminants) in the air breathed by any person is defined by the Health and Safety Executive in a list of Occupational Exposure Limits (OEL), Guidance Note EH 40. The guidance note is revised annually and reference should always be made to the most recent edition. A long exposure limit (8 hour Twa value) of 5 mg/m³ for particulate welding is included in the current OEL recommended limits list. The analysis of fume from wires for welding of Copper alloys indicates that a total particulate fume concentration of 5 mg/m³ no individual constituent of the fume will exceed its own recommended limit. There are however consumables (welding products) which give fume containing elements such as copper, manganese in sufficient quantity that even at 5mg/m³ their own limits would be exceeded. In these cases greater degree of fume control protection is required to ensure that welders and others are not exposed to excessive amounts of these elements. Consumables giving fumes of this nature are listed in Table 1. which also includes guidance on the maximum concentration of total particulate fume allowable in MIG WELD GmbH Deutschland · Wattstraße 2 · 94405 Landau a. d.

order to protect workers from the main constituents present in the fume. Table 1. gives the chemical composition of the particulate fume evolved during use of the range of welding consumables, analysis being of the fume generated in an enclosed Swedish box type apparatus. The chemical composition of the fume is expressed as weight per cent of elements, as is conventional rather than as oxides and silicates and other complex forms in which they actually exist. The analysis is not a complete analysis, the balance of the fume from MIG consisting of complex oxides of some or all of the constituents in the filler metal. The gases Nitric Oxide, Nitrogen Oxide and Ozone may sometimes be produced by the action of the electric arc or the radiation from it on the surrounding air. These gases do not arise from the welding consumable and are usually not a problem under conditions of normal ventilation. MIG welding is more likely to give rise to these gases particularly at high current levels and ozone generation may be increased by the presence of Argon in the atmosphere around the arc. 5. FIRST-AID MEASURES a. By fume and gas emissions. The hazards to health when they are inhaled or swallowed, contact your medical department or doctor. 6. FIRE-FIGHTING MEASURES a. Welding wires are not inflammable under ordinary conditions and do not present a fire or explosion risk. Packaging could be inflammable and the usual precautions to prevent fire should be observed. Welding consumables should not be allowed to come in contact with acids or other substances which are corrosive to metals or with oxidising agents nor with any other chemical substances with which any reaction may occur. 7. ACCIDENTIAL RELEASE MEASURES a. Welders should wear normal protective clothing and eye protection appropriate to electric arc welding, made of approved material. Gloves should be soft and pliable and should have gauntlets long enough to protect wrists and lower arms. 8. HANDLING AND STORAGE a. No special precautions need to be followed in handling these welding rods or wire in both storage and handling. b. Avoidance of contact with incompatible materials see section 5.a. 9. EXPOSURE CONTROLS / PERSONAL PROTECTION a. Welders should wear normal protective clothing and eye protection appropriate to electric arc welding ventilation and for fume extraction must be adequate to keep fume concentration within safe limits.
