Hazards and Protection.
Storage
Store in a cool, dry place. Store in a tightly closed container.
D2B
Protection
Wear chemical splash goggles, protective gloves and clothing.
Respirators
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
Small spills/leaks
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately.
Stability
Stable at room temperature in closed containers under normal storage and handling conditions.
Incompatibilities
Strong bases, strong oxidizing agents, strong reducing agents.
Decomposition
Oxides of carbon.

Fire.
Flash Point,°C
107
Fire fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use water spray, dry chemical, carbon dioxide, or chemical foam to extinguish.
Hazards
Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas.
Combustion products
During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.

First aid
 
   Ingestion
Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. Wash mouth out with water.
   Inhalation
Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation.
   Skin
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
