Hazards and Protection.
Storage
Storage requirements: even slightly flammable materials should be isolated from oxidizers.Storage area should be kept cool and ventilated and should be fireproof.
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
Wear appropriate protective gloves, clothing and goggles.
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.

Fire fighting
See amyl alcohol. Alcohol foam. Dry chemical.
Fire potential
Dangerous, when exposed to heat or flame; can react with oxidizing materials.
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
Fire may produce irritating, corrosive and/or toxic gases.

Exposure effects
Headache, dizziness, giddiness, ataxia, sedation and coma may occur.
   Ingestion
Nausea, vomiting, and diarrhea are common. Gastrointestinal hemorrhage can occur.
   Inhalation
Inhalation causes pulmonary tract irritation and rarely pulmonary edema. Severe respiratory depression or death has not been reported after inhalation.
   Skin
Dermatitis of varying severity may be noted. Drying and fissuring of the skin may be noted following chronic exposure.
   Eyes
See Inhalation.

First aid
 
   Ingestion
Seek medical assistance.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
