3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Flammable. Irritating to eyes and skin.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of contact, immediately wash skin with soap and copious
amounts of water.
AFTER EYE CONTACT
In case of contact, immediately flush eyes with copious amounts
of water for at least 15 minutes.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.
5 - Fire Fighting Measures
EXTINGUISHING MEDIA
Suitable: Carbon dioxide, dry chemical powder, or appropriate
foam.
Unsuitable: Carbon Dioxide, dry chemical powder, or appropriate
foam. Water can be applied as a spray or fog and if properly
applied is capable of extinguishing the fire by sweeping the
flames off the surface of the burning liquid.
SPECIAL RISKS
Specific Hazard(s): Flammable liquid. Emits toxic fumes under
fire conditions.
Explosion Hazards: Vapor may travel considerable distance to
source of ignition and flash back. Container explosion may occur
under fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
6 - Accidental Release Measures
PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area. Shut off all sources of ignition.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear respirator, chemical safety goggles, rubber boots, and
heavy rubber gloves.
METHODS FOR CLEANING UP
Cover with dry-lime, sand, or soda ash. Place in covered
containers using non-sparking tools and transport outdoors.
Ventilate area and wash spill site after material pickup is
complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Avoid breathing vapor. Avoid
contact with eyes, skin, and clothing. Avoid prolonged or
repeated exposure.
STORAGE
Conditions of Storage: Keep container closed. Keep away from
heat, sparks, and open flame.
8 - Exposure Controls / Personal Protection
