Hazards and Protection.
Keep container closed. Keep away from heat, sparks, and open flame. Store in a cool dry place. Handle and store under nitrogen.
Compatible chemical-resistant gloves. Chemical safety goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.
Stable at normal temperatures and pressures. Sensitive to air.
Strong acids, Strong oxidizing agents.
Carbon monoxide, Carbon dioxide, Arsenic oxides.
Extinguish using 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.
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
Fire may produce irritating, corrosive and/or toxic gases.
Toxic. Dangerous for the environment. Toxic by inhalation and if swallowed. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
Toxic if swallowed.
Vapors may cause dizziness or suffocation. May cause irritation or burns.
May cause irritation or burns.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Wash skin with soap and water. Flush with running water for at least 20 minutes
Flush with running water for at least 20 minutes.
