Fire Fighting：

Fire Extinguishing Agents Not to Be Used: Water may be ineffective. Fire Extinguishing Agents: Foam, carbon dioxide, dry chemical. (USCG, 1999)

Isolation and Evacuation：

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 feet). FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Nonfire Spill Response：

Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. 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. LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces. (ERG, 2016)

Personal Protective Equipment：

Rubber or neoprene gloves, splash goggles and NIOSH approved self-contained breathing apparatus. (USCG, 1999)

Toxicity

Toxicity class：

practically nontoxic

Drug Information

Health Hazards：

INHALATION: May produce anesthetic effects. EYES: Moderate eye irritation possible. (USCG, 1999)

First Aid：

Call a doctor. INHALATION: Remove from contaminated atmosphere. If respiration is labored, administer oxygen. If unconscious, administer artificial respiration. EYES: Flush with clear tap water for 15 min. SKIN: Wash with soap and water. INGESTION: Do not induce vomiting. Physician may remove by cuffed tube lavage. (USCG, 1999)
