Hazards and Protection.
Store in a cool, dry place. Keep container closed when not in use.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.
Eyes: Wear safety glasses and chemical goggles if splashing is possible. Skin: Wear appropriate protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment.
Stable under normal temperatures and pressures.
Strong oxidizing agents - strong acids _ strong bases _ - strong reducing agents _ moisture.
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen.
Upper exp. limit, %
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Slight risk when exposed to heat or flame. Can react with oxidizing materials.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Fire may produce irritating, corrosive and/or toxic gases.
TOXIC; inhalation, ingestion, or skin contact with material may cause severe injury or death. Effects of contact or inhalation may be delayed.
Contact with molten substance may cause severe burns to skin and eyes. See Inhalation.
Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Remove from exposure to fresh air immediately.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.
