Most important symptoms/effects, acute and delayed: May cause eye irritation. Causes skin irritation with redness
and drying. Inhalation may cause respiratory irritation and central nervous system effects. Harmful or fatal if
swallowed. Aspiration during swallowing or vomiting may cause lung damage. May cause cancer based on animal
data.

Indication of immediate medical attention and special treatment, if necessary: Immediate medical attention is
required for ingestion.

SECTION 5 FIRE and EXPLOSION HAZARD DATA

Suitable extinguishing media: Use water fog, foam, carbon dioxide, or dry chemical. Do not use a steady stream of
water. Product may float on the surface of water and create a floating fire hazard.
Specific hazards arising from the chemical: This product is highly flammable and forms explosive mixtures with air.
Vapors are heavier than air and will travel along surfaces to remote ignition sources and flash back. Closed containers
may explode if exposed to extreme heat. Combustion may produce carbon oxides and other products of incomplete
combustion.
Special protective equipment and precautions for fire-fighters: Firefighters should wear full emergency
equipment and a NIOSH approved positive pressure self-contained breathing apparatus. Cool fire exposed container
with water. Do not allow run-off from firefighting to enter drains or water courses.

SECTION 6 ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment, and emergency procedures: Wear appropriate protective
equipment. Eliminate ignitions sources and ventilate the area with explosion proof equipment. Wash thoroughly after
handling.
Environmental hazards: Avoid release into the environment. Report spill as required by local and federal
regulations.
Methods and materials for containment and cleaning up: Contain with an inert absorbent and place into a
closable container for disposal. Use non-sparking tools and equipment. If spill has not ignited, use water spray to
disperse the vapors and protect personnel attempting to stop leak. Prevent entry in storm sewers and waterways.
Runoff can cause a fire or explosion hazard in sewers.

SECTION 7 HANDLING and STORAGE

Precautions for safe handling: Avoid contact with eyes, skin and clothing. Avoid breathing vapors. Wash
thoroughly after handling. Use only with adequate ventilation. Wash thoroughly with soap and water after handling.
Keep containers closed when not in use. Keep product away from heat, sparks, flames and all other sources of
ignition. Do not permit smoking in use or storage areas. Use with non-sparking tools and explosion proof equipment.
Electrically bond and ground containers for transfer

Do not cut, drill, grind or weld on or near containers, even empty containers. Empty containers retain product residues
can be hazardous. Follow all SDS precautions when handling empty containers.

Conditions for safe storage, including any incompatibilities: S Store in accordance with regulations for the
storage of flammable liquids. Store in a dry, well ventilated area away from heat, direct sunlight and all sources of
ignition. Store away from oxidizers and other incompatible materials. Protect containers from physical damage.

10 ppm, skin TWA ACGIH TLV

Appropriate engineering controls: Use with local exhaust ventilation to maintain exposures below the occupational
exposure limits. Use explosion proof equipment where required

Respiratory protection: If exposures are exceeded, use a NIOSH approved organic vapor respirator appropriate for
the form and concentration of the contaminants should be used. Selection of respiratory protection depends on the
contaminant type, form and concentration. Select in accordance with OSHA 1910.134 and good Industrial Hygiene
practice.
Skin protection: Impervious gloves such as nitrile rubber recommended to prevent skin contact.
Eye protection: Wear chemical safety goggles to avoid eye contact.
Other: Impervious coveralls, apron and boots is required to prevent skin contact and contamination of personal
clothing. A safety shower and eye wash should be available in the immediate work area.
