Hazards and Protection.
Store in a cool, dry, well-ventilated area away from incompatible substances. Keep containers tightly closed.
Wash thoroughly after handling. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Avoid ingestion and inhalation.

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.
Combustible material: may burn but does not ignite readily.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Fire may produce irritating, corrosive and/or toxic gases.
Causes irritation of the digestive system, respiratory tract, skin and eyes. Toxic on contact.
May cause digestive tract disturbances.
May cause respiratory tract irritation.
Causes severe skin irritation. May be fatal if absorbed through the skin.
Causes severe eye irritation.
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.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
