Hazards and Protection.
Store in a cool, dry place. Store in a tightly closed container.
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Use only in a chemical fume hood.
Eyes: Wear chemical goggles. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear a chemical apron.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container.
Strong bases, strong oxidizing agents.
Hydrogen chloride, nitrogen oxides, carbon monoxide, carbon dioxide, hydrogen fluoride.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Combustible material: may burn but does not ignite readily.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Fire may produce irritating, corrosive and/or toxic gases.
In severe intoxications, a rapidly progressing and profound coma may occur. Seizures may occur following significant exposures.
Harmful if swallowed. The toxicological properties of this substance have not been fully investigated.
Harmful if inhaled. The toxicological properties of this substance have not been fully investigated.
Harmful if absorbed through the skin.
May cause eye irritation.
Get medical aid. Wash mouth out with water.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
