3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Flammable. Harmful by inhalation. Irritating to 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 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): Vapor may travel considerable distance to
source of ignition and flash back.
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.
SPECIFIC METHOD(S) OF FIRE FIGHTING
Use water spray to cool fire-exposed containers.
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 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. Avoid
contact with eyes, skin, and clothing.
STORAGE
Conditions of Storage: Keep tightly closed. Keep away from heat,
sparks, and open flame. Store in a cool dry place.
8 - Exposure Controls / Personal Protection
ENGINEERING CONTROLS
Mechanical exhaust required. Safety shower and eye bath. Use
