Section 5 - FIRE FIGHTING MEASURES
  General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Flammable liquid and vapor. Vapors may form an explosive mixture with air.
Extinguishing Media:
Use water fog, dry chemical, carbon dioxide, or regular foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
  General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container.

Section 7 - HANDLING and STORAGE
  Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Ground and bond containers when transferring material. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Flammables-area.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
  Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits CAS# 4454-05-1: Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
