Hazards and Protection.
Storage
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water.
Handling
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.
Protection
Protect against both inhalation and absorption through the skin. Wear protective clothing including niosh approved rubber gloves and boots, safety goggles or face mask, and either a respirator whose canister is specifically approved for this material, or a self-contained breathing apparatus.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
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.
Stability
Containers may rupture when exposed to heat.
Incompatibilities
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products.

Fire fighting
Fire Extinguishing Agents Not to Be Used: Water may be ineffective.Fire Extinguishing Agents: Water fog in conjuction with alcohol foam, dry chemical or carbon dioxide.
Fire potential
Very flammable. Flammable liquid.
Hazards
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.
Combustion products
When heated emits acrid fumes.

Health.
Exposure effects
   Ingestion
See inhalation.
   Inhalation
INHALATION AND INGESTION: Irritates the mucous membrane, depresses the central nervous system and is narcotic. Damage to kidney, liver, and lung can occur. Ingestion may irritate gastro-intestinal tract. EYES: Irritation. SKIN: Irritation.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Remove from exposure. Administer oxygen if needed.
   Skin
Remove contaminated clothing and shoes. Wash with soap and water. Subsequent treatment is symptomatic and supportive in nature.
   Eyes
Flush with water for at least 15 min.
