SECTION 2: Hazards identification

There are no recognised hazards associated directly with unused welding consumables prior to welding. Packaged consumables may be heavy, and should be handled and stored with care. FOLLOW MANUAL HANDLING REGULATIONS. When using these rods as part of the welding process additional potential hazards are likely: Hot metal spatter and heat from the welding flame, which can cause burns to the hands and body, and may cause fire if in contact with combustible materials. Radiation from the welding flame, which can produce skin burns and possible eye damage to unprotected eyes. WEAR SUITABLE PROTECTIVE EQUIPMENT. Fumes produced from the welding consumable, material being welded, and the welding flame: Particulate fume such as complex metal oxides and silicates from the weld materials. Gaseous fume such as carbon monoxide and dioxide from the oxidation of carbon in the components and from the flame combustion products. SHORT TERM INHALATION OF THESE FUMES AND GASES MAY LEAD TO IRRITATION OF THE NOSE, THROAT AND EYES. LONG TERM OVEREXPOSURE OR INHALATION OF HIGH LEVELS OF FUMES MAY RESULT IN HARMFUL EFFECTS TO THE RESPIRATORY SYSTEM, CENTRAL NERVOUS SYSTEM AND LUNGS. LOCAL EXTRACTION AND /OR VENTILATION SHOULD BE USED TO ENSURE THAT ALL HAZARDOUS INGREDIENTS IN THE FUME ARE KEPT BELOW THEIR INDIVIDUAL OCCUPATIONAL EXPOSURE STANDARDS IN THE WELDER’S AND OTHER WORKERS’ BREATHING ZONES. NOTE: If welding is performed on plated or coated materials such as galvanised steel, excessive fume may be produced which contains additional hazardous components, and may result in metal fume fever and other health effects.
