[Fire Fighting]

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Containers may explode when heated. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. Cool containers with flooding quantities of water until well after fire is out.

[Fire Potential]

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
[Ingestion]

Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid.
[Inhalation]

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
[Skin]

Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
[Eyes]

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
[Storage]

Store in a cool, dry place. Do not store in direct sunlight. Store in a tightly closed container. Do not expose to air.
[Handling]

Wash thoroughly after handling. Wash hands before eating. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid breathing dust, vapor, mist, or gas. Take precautionary measures against static discharges. Do not get on skin or in eyes. Avoid ingestion and inhalation.
[Ingestion]

May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
[Inhalation]

May cause respiratory tract irritation. Inhalation of vapor may cause respiratory tract irritation.
[Skin]

Causes severe skin irritation. Harmful if absorbed through the skin.
[Eyes]

Causes severe eye irritation.
[Hazards]

Contact with metals may evolve flammable hydrogen gas.
