Lower (LEL): 1.1%
Upper (UEL): 7.5%
FIRE EXTINGUISHING MATERIALS:
Water Spray: YES (for cooling only)
Carbon Dioxide: YES
Foam: YES
Dry Chemical: YES
Halon: YES
Other: Any "B" Class.
UNUSUAL FIRE AND EXPLOSION HAZARDS: This is a Class IB flammable liquid. When involved in a
fire, this material may decompose and produce toxic gases (including carbon monoxide and carbon
dioxide). The vapors of Hexane and its isomers are heavier than air and may spread long distances;
distant ignition and flashback are possible. Hexane and its isomers can float on water; therefore, water
contaminated with Hexane and its isomers can spread the flammable liquid and can spread fire.
Explosion Sensitivity to Mechanical Impact: Contents under pressure. May explode if impacted or
punctured.
Explosion Sensitivity to Static Discharge: Static discharge may cause Hexane and its isomers to ignite.
SPECIAL FIRE-FIGHTING PROCEDURES: Structural firefighters must wear Self-Contained Breathing
Apparatus and full protective equipment. Incipient fire responders should wear eye protection. Move
fire-exposed cylinders if it can be done without risk to firefighters. Water spray can be used to cool
fire-exposed containers. Water fog or spray can also be used by trained firefighters to disperse the
vapors of Hexane and its isomers and to protect personnel. Stop the leak or discharge, if possible. For
small releases, if it is not possible to stop the leak, and it does not endanger personnel, let the fire
burn itself out. If this product is involved in a fire, fire runoff water should be contained to prevent
possible environmental damage.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
PRECAUTIONS IN CASE OF SPILL: Contain spill as quickly as possible. Keep flowing material away
from heat, sparks, or open flames. Do not smoke near a spill. Use clay (Oil Dry™), sand, earth, etc. to
absorb the spill. Put material into a suitable steel drum which can be closed securely.
WASTE DISPOSAL: Bury in an approved landfill according to federal, state, and local regulations.
Empty containers that have been completely emptied and the residue allowed to dry are not
considered hazardous waste.
SECTION 7 - HANDLING & STORAGE
HANDLING & STORAGE PRECAUTIONS: Store away from heat, sparks, and open flames. Solvent
vapors are heavier than air and may be moved from the source location by ventilation systems to
points far away. Do not store near oxidizers.
OTHER PRECAUTIONS: Keep container closed when not in use. Store in a dry ventilated area. Maintain
package labeling during storage.
SECTION 8 - EXPOSURE CONTROL / PERSONAL PROTECTION
VENTILATION: Use natural cross ventilation, local (mechanical) pick-up, and/or general area
mechanical cross ventilation. Ventilation pattern should be designed to prevent accumulation of
heavier than air solvent vapors. Ventilation must be sufficient to maintain solvent vapor concentrations
below the TLV.
