Hazards and Protection.
Store at -20 C. Keep containers tightly closed. Store under inert atmosphere.
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing.
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.
Sweep up, place in a bag and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.
Stable if stored at recommended conditions.
Strong oxidizing agents, Bases.
Carbon monoxide, Carbon dioxide, Hydrogen chloride gas, Phosgene gas.
Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Emits toxic fumes under fire conditions.
Danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. Irritating to eyes and skin. Limited evidence of a carcinogenic effect. Target organs: Liver. Kidneys. Eyes. Heart. Central nervous system. Cardiovascular system. Blood. May cause nervous system disturbances. Exposure to and/or consumption of alcohol may increase toxic effects.
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
