3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Highly flammable. Harmful in contact with skin and if swallowed.
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 skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician.
5 - Fire Fighting Measures
EXTINGUISHING MEDIA
Suitable: Water spray. Carbon dioxide, dry chemical powder, or
appropriate foam.
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 can occur
under fire conditions. In advanced or massive fires the area
should be evacuated and the fire should be fought from a remote
explosion-resistant location.
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 self-contained breathing apparatus, 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: Do not breathe 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
ENGINEERING CONTROLS
Safety shower and eye bath. Use nonsparking tools. Mechanical
exhaust required.
GENERAL HYGIENE MEASURES
Wash thoroughly after handling. Wash contaminated clothing before
reuse.
