• Toxic by ingestion.
• Vapors may cause dizziness or suffocation.
• Exposure in an enclosed area may be very harmful.
• Contact may irritate or burn skin and eyes.
• Fire may produce irritating and/or toxic gases.
• Runoff from fire control may cause environmental contamination.

• Some of these materials may burn, but none ignite readily.
• Most vapors are heavier than air.
• Air/vapor mixtures may explode when ignited.
• Container may explode in heat of fire.

• CALL 911. Then call emergency response telephone number on shipping paper. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
• Keep unauthorized personnel away.
• Stay upwind, uphill and/or upstream.
• Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks, etc.).
• Ventilate closed spaces before entering, but only if properly trained and equipped.

• Wear positive pressure self-contained breathing apparatus (SCBA).
• Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.
• Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

Immediate precautionary measure.

• Isolate spill or leak area immediately for at least 50 meters (150 feet) in all directions.

• Consider initial downwind evacuation for at least 100 meters (330 feet).

• 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.

• Dry chemical, CO₂ or water spray.

• Dry chemical, CO₂, alcohol-resistant foam or water spray.
• If it can be done safely, move undamaged containers away from the area around the fire.
• Dike fire-control water for later disposal; do not scatter the material.

• Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
• Cool containers with flooding quantities of water until well after fire is out.
• Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
• ALWAYS stay away from tanks engulfed in fire.

• ELIMINATE all ignition sources (no smoking, flares, sparks or flames) in immediate area.
• Stop leak if you can do it without risk.

• Pick up with sand, earth or other non-combustible absorbent material.

• Dike far ahead of liquid spill for later disposal.
• Prevent entry into waterways, sewers, basements or confined areas.
