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. Vapors can travel to a source of ignition and flash back. Will burn if involved in a fire.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.

Section 10 - STABILITY AND REACTIVITY
Chemical Stability:
Prolonged exposure to air and sunlight may form unstable peroxides.
Explosive peroxides may form on concentration. Peroxides can be detonated by friction, impact, or heating. Peroxide formation may occur in containers that have been opened and remain in storage.
Normally stable; however, on long term storage, materials containing similar functional groups form peroxides of unknown stability.
Conditions to Avoid:
Excess heat, organic materials.
Incompatibilities with Other Materials:
Strong oxidizing agents - air.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide, oxides of boron, borane.
Hazardous Polymerization: Has not been reported.
