Products of combustion :
In case of fire, use water spray (fog), foam, dry chemicals, or CO 2.
Fire fighting media and :
instructions
Flammable liquid and vapor. Vapor may cause flash fire. Vapors may accumulate in
low or confined areas, travel considerable distance to source of ignition and flash back.
Runoff to sewer may create fire or explosion hazard.
: Fire fighters should wear appropriate protective equipment and self-contained breathing

absorbent (soil may be used in the absence of other suitable materials) and use a non-
sparking or explosion proof means to transfer material to a sealed, appropriate container
for disposal. For large spills dike spilled material or otherwise contain material to ensure
runoff does not reach a waterway. Place spilled material in an appropriate container for
disposal.
Section 7. Handling and storage
: Do not ingest. Avoid contact with eyes, skin and clothing. Keep container closed. Use
Handling
only with adequate ventilation. Avoid breathing vapor or mist. Keep away from heat,
sparks and flame. To avoid fire or explosion, dissipate static electricity during transfer by
grounding and bonding containers and equipment before transferring material. Use
explosion-proof electrical (ventilating, lighting and material handling) equipment. Wash
thoroughly after handling.
Extremely hazardous liquid and vapor under pressure.
: Store in a segregated and approved area. Keep container in a cool, well-ventilated area.
Storage
Keep container tightly closed and sealed until ready for use. Avoid all possible sources
of ignition (spark or flame).
