Hazards and Protection.
Keep away from sources of ignition. Store in a cool, dry place. Do not store in direct sunlight. Store in a tightly closed container. Flammables-area. Refrigerator/flammables.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate safety goggles, protective clothing and gloves.
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.
Make no contact with the spilled material. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. 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 under normal temperatures and pressures.
Avoide contact with strong oxidizing agents and acids.
Nitrogen oxides, carbon monoxide and carbon dioxide are produced upon decomposition.
Wear a self-contained breathing apparatus inpressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Will burn if involved in a fire. In case of fire use water spray, dry chemical, carbon dioxide, or chemical foam.
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 will produce irritating, corrosive and/or toxic gases.
Poison by ingestion. Causes gastrointestinal tract burns.
Causes chemical burns to the respiratory tract.
Get medical aid immediately. Wash mouth out with water.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid immediately.
