instructions
Highly 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

unnecessary personnel away. Use suitable protective equipment (Section 8). Do not
touch or walk through spilled material.
Environmental precautions : Avoid dispersal of spilled material and runoff and contact with soil, waterways, drains
and sewers.
: If emergency personnel are unavailable, contain spilled material. For small spills add

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
: Keep container closed. Use only with adequate ventilation. 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.
: 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).
