SECTION 2: Hazards identification

Classification Classification under South African Hazardous Chemical Substances Regulations subsequently amended HCS) Classification under the Globally Harmonized System of classification and labelling of chemicals (GHS) Emergency Colour: Generally greyish, but other Overview colours can be present Odour: Odourless Taste: Not applicable Physical State: Solid Form: Metal wire with flux coating Main Hazards - When using these electrodes as part of the welding process additional potential hazards are likely. - Electric shock from the welding equipment or electrode. This can be fatal. - There are no recognised associated directly with unused welding consumables prior to welding. Adverse Health - Some low levels of dust may be produced Effects during handling. Do not breathe the dust. Chemical - Hot metal spatter and heat during welding may cause fire if in contact with combustible materials. Biological - Fumes produced from the welding consumable, material being welded, and the arc radiation. - Short term inhalation of these fumes and gases may lead to irritation of the nose, throat and eyes. high levels of fumes may result in harmful effects to the respiratory system, central nervous system and lungs. Vapour - Particulate fume such as complex metal Inhalation oxides, fluorides, and silicates from the weld materials. - Gaseous fume such as ozone and nitrogen oxides from the action of arc radiation on the atmosphere, and carbon monoxide and dioxide from the dissociation and reaction of some of the flux constituents. - 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. Eye Contact - UV, IR, and light radiation from the arc, which can produce ‘arc eye’ and possible eye damage to unprotected eyes. Wear suitable protective equipment. Skin Contact - No known effect associated with unused welding consumables prior to welding. - Hot metal spatter and heat can cause burns to the hand and body during welding. Ingestion - Considered unlikely due to product form. GHS - Specific target organ toxicity, repeated
