Notes to Physician: 
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. Will burn if involved in a fire. Flammable liquid and vapor. 
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical 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. Remove all sources of ignition. Use a spark-proof tool. 
Section 7 - Handling and Storage 
Handling: Use spark-proof tools and explosion proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. 
Storage: Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Flammables-area. 
Section 8 - Exposure Controls, Personal Protection 
Engineering Controls: 
 Use adequate ventilation to keep airborne concentrations low. 
Exposure Limits
 CAS# 496-11-7:
 
Personal Protective Equipment 
Eyes: Wear appropriate protective eyeglasses or chemical safety ggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
