facepiece operated in positive pressure mode. Move containers from fire area if it can be done without
risk. Use water to keep fire-exposed containers cool.
Unusual Fire & Explosion Hazards:
Vapors may flow along surfaces to distant ignition sources and flash back. Closed containers exposed to
heat may explode. Contact with strong oxidizers may cause fire.

PREVENTATIVE MEASURES
========================================================================
Ventilation:
Use adequate general or local exhaust ventilation to keep vapor and mist levels as low as possible.
Respiratory Protection:
None required where adequate ventilation conditions exist. If airborne concentration is high, a chemical
cartridge respirator with organic vapor cartridge is recommended. If concentration exceeds capacity of
cartridge respirator, a self-contained breathing apparatus is advised.
Eye/Skin Protection: Safety goggles, uniform, apron, rubber gloves are recommended.
Storage Requirements:
Keep container tightly closed. Store in a cool, dry, well-ventilated, flammable liquid storage area.
Special Precautions: Bond and ground containers when transferring liquid.

ENVIRONMENTAL PROTECTION DATA
========================================================================
Steps To Be Taken In The Event Of A Spill Or Discharge:
Wear self-contained breathing apparatus and full protective clothing. Shut off ignition sources; no flares,
smoking or flames in area. Stop leak if you can do so without risk. Use water spray to reduce vapors.
Take up with sand or other non-combustible absorbent material and place into container for later
disposal. Flush area with water.
