SECTION 2: Hazards identification

OSHA There are no immediate hazards with these electrodes. The chief acute health hazard associated with these products is inhalation of fumes during welding operations. The Inhalation of fumes generated by welding or dusts and powders, formed if grinding operations are performed on the product. Those electrodes that contain Thorium Oxide have a special hazard if dusts or powders are produced and inhaled during use or grinding of tips of the electrodes, as thorium compounds are suspected of being cancer-causing compounds. When exposed to extremely high temperatures, these products will produce irritating oxides of cerium, thorium, tungsten and zirconium. These electrodes present no significant fire hazard; however finely divided metal powder which may be generated during grinding of the tips of electrodes, is highly flammable (especially when exposed to oxidizing compounds at elevated temperatures). In some circumstances, powdered tungsten can be spontaneously flammable. CARCINOGENICITY STATUS: Chemicals in these electrodes are listed, as follows. THORIUM OXIDE IARC-1, Carcinogenic to Humans ZIRCONIUM OXIDE TLV-A4, Not Classifiable as to Human Carcinogenicity

Remove contact lenses if present and easy to do – continue rinsing. If eye irritation persists seek medical advice / attention P342+P311 IF experiencing respiratory symptoms Call a POISON CENTER and / or doctor / physician P302+P352 IF ON SKIN Wash with plenty of soap and water P333+P313 IF skin irritation or rash occurs Get medical advice / attention P363 Wash contaminated clothing before reuse P308+P311 IF exposed or concerned Seek medical advice / attention. Collect spillage P402+P404 Store in a dry place. Store in a closed container For thoriated tungsten electrodes, store in tightly closed containers in a cool and well-ventilated area. Nobody should remain permanently or longer than necessary in close proximity to the stored thoriated tungsten electrodes as the electrodes may emit alpha, beta and gamma radiation. Additional measures should be taken to protect from such possible alpha, beta and gamma radiation. Thoriated tungsten electrodes may be incompatible with some strong acids. P501 Dispose of contents and container in accordance with local regional / national international regulations.
