Hazards and Protection.
Keep tightly closed. Store in a cool dry place.
Compatible chemical-resistant gloves. Chemical safety goggles. Protective clothing. Faceshield (8-inch minimum).
Cover with dry-lime, sand, or soda ash. Place in covered containers using non-sparking tools and transport outdoors. Ventilate area and wash spill site after material pickup is complete.
Water, Alcohols, Oxidizing agents, Strong bases.
Carbon monoxide, Carbon dioxide, Hydrogen chloride gas, Phosgene gas.
DO NOT USE WATER. Use carbon dioxide or dry chemical powder. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.
Water hydrolyzes material liberating acidic gas which in contact with metal surfaces can generate flammable and/or explosive hydrogen gas.
Emits toxic fumes under fire conditions. Corrosive. Lachrymator.
Harmful if swallowed, inhaled, or absorbed through skin. Causes burns. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting. Inhalation may result in spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Material is extremely destructive to tissue of the mucous membranes and upper respiratory tract, eyes, and skin.
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.
