Section 8. Exposure controls/personal protection
EYE PROTECTION:
Wear safety glasses or chemical goggles to prevent eye contact. Do not wear
contact lenses when working with this substance. Have eye baths readily
available where eye contact can occur.
SKIN PROTECTION:
Wear impervious gloves and protective clothing to prevent skin contact.
Suggested protective materials are: Polyvinyl alcohol, Polyethylene and
Viton. Provide safety showers at any location where skin contact can occur.
RESPIRATORY PROTECTION:
Use NIOSH or MSHA approved equipment when airborne exposure limits are exceeded.
NIOSH/MSHA approved breathing equipment may be required for non-routine and
emergency use. Ventilation may be used to control or reduce airborne
concentrations.

BASIC FIREFIGHTING PROCEDURES:
Use dry chemical, all purpose or polar AFFF foam or water spray to extinguish
fire. Water or foam may cause frothing, with further application leading to
boilover. Foam may have limited effectiveness on three dimensional fires.
Use water spray to cool fire-exposed containers, structures and to protect
personnel. Use water to flush spills away from source of ignition. Do not
flush down public sewers.
UNUSUAL FIRE AND EXPLOSION HAZARDS:
Fire may produce poisonous or irritating gas, fumes or vapor. Excessive heat
may trigger polymerization of confined material. Containers may explode in
heat of fire. Styrene vapors are uninhibited and may form polymers in vents
or flame arrestors of storage tanks, resulting in stoppage of vents. Exposed
firefighters should wear MSHA/NIOSH approved self-contained breathing
apparatus, with full face mask and full protective equipment.
Section 10. Stability and reactivity
STABILITY/INCOMPATIBILITY:
Stable under normal conditions of use. Avoid contact with strong oxidizers.
HAZARDOUS REACTIONS/DECOMPOSITION PRODUCTS:
Thermal decomposition products may be hazardous. Reacts vigorously with
oxidizing agents. "Empty" containers may contain toxic, flammable/combustible
or explosive residue or vapors. Do not cut, grind, drill, weld or reuse
containers unless adequate precautions are taken against these hazards.
