Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.
Stable under normal shipping and handling conditions.
Incompatible with boric oxide + calcium oxide, and bromine trifluoride; react with zinc to form explosive hydrogen gas; catalyzes exothermic polymerization of vinyl ether; explodes at room temperature when added to furan-2-peroxycarbolic acid; and undergoes an exothermic (heat-producing) reaction with water.
Chlorine, irritating and toxic fumes and gases.
Substance is noncombustible. Substance is noncombustible; use agent most appropriate to extinguish surrounding fire.
F (Not subject to toxicity classification)
May cause digestive tract and cardiac disturbances. May cause kidney damage.
May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause cardiac disturbances. May cause central nervous system depression. May cause seizures, rapid respiration, slow heartbeat and death.
May cause severe irritation of the upper respiratory tract with pain, burns, and inflammation. Exposure produces central nervous system depression.
Contact with skin causes irritation and possible burns, especially if the skin is wet or moist.
Contact with eyes may cause severe irritation, and possible eye burns.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
