Special Fire Fighting Procedures: Move container from fire if possible. Cool fire-exposed containers with water spray if they cannot be moved. Avoid breathing vapors.

Unusual Fire and Explosion Hazards: Dangerous when exposed to heat or flame. Vapors are heavier than air and may flash back from a considerable distance from a source of ignition. Vapor-air mixtures are explosive above flash point.

HEALTH HAZARDS

Primary Routes of Entry: Inhalation, skin absorption

Inhalation: Nasal/throat irritation with laryngitis, bronchitis, and coughing. Possible central nervous symptoms such as headache, dizziness, drowsiness, weakness, confusion, nausea and general intoxication.

Skin: Irritation

Ingestion: Sore throat, headache, dizziness, and drowsiness followed by restlessness, gastritis,

nausea, vomiting, hematemesis, stupor, twitching, collapse, unconsciousness, convulsions and paralysis.

EMERGENCY AND FIRST AID

Inhalation: Remove patient to a location away from the source of exposure. Give oxygen if breathing in difficult. Seek medical attention.

Skin: Remove contaminated clothing and shoes. Wash affected area with large amounts of water until no evidence of chemical remains.

Eye: Wash immediately with large amounts of water until no evidence of chemical remains. Seek medical attention.

Ingestion: If victim is conscious, give 2 to 4 glasses of water and induce vomiting. Seek medical attention.

PROTECTIVE EQUIPMENT AND CONTROL MEASURES

Respiratory Protection: Wear respirator with organic vapor canister.
