Classification according to GHS

Classified according to the Globally Harmonised System of Classification and labelling of Chemicals (GHS) including Work, Health and Safety regulations, Australia.

2.1 Classification of the substance or mixture

These products (the rods) are classified as hazardous according to applicable GHS hazard classification criteria. EMERGENCY OVERVIEW: These products are hard, brittle, silvery-grey metal electrodes. The chief health hazard associated with these products would be the inhalation of fumes generated by welding or dusts and powdered, 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. Emergency responders must wear the proper personal protective equipment (and have appropriate fire-extinguishing protection) suitable for the situation to which the are responding.

Precautionary statements

P201 – Obtain special instruction before use P202 – Do not handle until all safety precautions have been read and understood P260 - Do not breathe dust/fume/gas/mist/vapours/spray P261 - Avoid breathing dust/fume/gas/mist/vapours/spray P261 – Avoid breathing dust/fume/gas/mist/vapours/spray P264 - Wash thoroughly after handling P270 - Do not eat, drink or smoke when using this product P272 – Do not eat, drink or smoke when using this product. P273 – Avoid release into the environment P280 – Wear protective gloves P284 - In case of inadequate ventilation wear respiratory protection P302+P352 - IF ON SKIN: Wash with plenty of soap and water P308+P311 – If exposed or concerned: Call a POISON CENTRE - Get medical advice/attention P333+P313 – if skin irritation or a rash occurs: Get medical advice/attention P305+P351+P338 – f in eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do – continue rinsing. If eye irritation persists, seek medical advice/attention. P342+311 - If experiencing respiratory symptoms: Call a POISON CENTER and / or doctor / physician. P363 - Wash contaminated clothing before reuse

Storage

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. P405 - Store locked up

Disposal
