Guidance on Safe Use
Administrative data
First-aid measures
Inhalation(dust/fume): Remove from exposure to fresh air immediately. If respiratory problems develop, get medical
aid as soon as possible.
Skin(dust): Immediately wash skin with plenty of water for at least 20 minutes. Removed contaminated
clothing and wash before reuse.
Eye contact (dust/chips): Immediately flush eyes with plenty of water for at least 20 minutes, lifting lids occasionally.
An eyewash station should be available in the work area.
Ingestion: Get medical attention if patient is unwell. Never give anything by mouth to an unconscious person. Rinse mouth with water.
Most important symptoms and effects, both acute and delayed:
To the best of our knowledge, the chemical, physical, and toxicological properties have not been thoroughly investigated.
Fire-fighting measures
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Special hazards arising from the substance or mixture:
Magnesium oxide
Precautions for fire-fighters:
Wear self contained breathing apparatus for fire fighting if necessary.
Accidental release measures
Ingot Form: Standard PPE (glasses, gloves, steel toe shoe, hard hat as necessary). During smelting, high heat protection, aluminized gear, etc. must be used.
Environmental precaution:
Ingot Form: No significant environmental concerns in this form. Keep dry to avoid oxidation of product.
Machine Turnings: Magnesium reacts with acid to form hydrogen gas and irritating fume and heat. In the presence of water only, flammable hydrogen gas and heat will be generated.
Clean up procedure:
Always wear personal protection equipment. Recover dry product for recycling. In finely divided form reaction with water is exothermic and hydrogen gas will be produced, ammonia may also be produced. Spillage should be removed when dry and kept in a clean and dry container.
Container should be watertight but if water or moisture is present, ventilate container and store outside, in order to avoid any hydrogen accumulation.
Handling and storage
Provide appropriate exhaust ventilation at places where dust is formed.Minimize dust generation and accumulation.
With dust or fines avoid contact with eyes, skin
and clothing. Avoid inhalation and ingestion. Do not allow contact with water.
Conditions for safe storage, including any incompatibilities:
Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
If exposed to moisture ingot products may develop oxidation or other cosmetic damage.
Machine turnings or fines may generate hydrogen and/or ammonia and heat when exposed to moisture.
Specific end uses:
