3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Highly flammable. Harmful if swallowed. Irritating to respiratory
system and skin. Risk of serious damage to eyes.
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: Water may be effective for cooling, but may not
effect extinguishment.
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. Forms explosive mixtures in air.
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. Use nonsparking
tools.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Cover with an activated carbon adsorbent, take up and place in
closed containers. Transport outdoors. Ventilate area and wash
spill site after material pickup is complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Do not breathe vapor. Do not get
in eyes, on skin, on clothing. Avoid prolonged or repeated
exposure.
STORAGE
Conditions of Storage: Keep tightly closed. Keep away from heat,
sparks, and open flame.
8 - Exposure Controls / Personal Protection
ENGINEERING CONTROLS
Safety shower and eye bath. Use nonsparking tools. Mechanical
