Fire Hazards in Presence of Various Substances:
Slightly flammable to flammable in presence of open flames and sparks, of heat.
Non-flammable in presence of shocks.
Explosion Hazards in Presence of Various Substances:
Slightly explosive in presence of open flames and sparks.
Non-explosive in presence of shocks.
Fire Fighting Media and Instructions:
Flammable solid.
SMALL FIRE: Use DRY chemical powder.
LARGE FIRE: Use water spray or fog. Cool containing vessels with water jet in order to prevent pressure
build-up, autoignition or explosion.
Special Remarks on Fire Hazards:
Material in powder form, capable of creating a dust explosion.
When amorphous boron is heated in dry ammonia, reaction proceeds with incandescence and hydrogen is evolved.
Boron ignites in bromine vapor at 700 C.
Boron ignites in chlorine @ 410 C.
Fluorine attacks boron @ ordinary temperature and the resulting mass becomes incandescent.
Iodic acid attacks boron below 40 deg. C and the resulting mass becomes incandescent.
Concentrated nitric acid and boron react so violently that the mass is raised to incandescence.
A mixture of boron and sulfur becomes incandescnet at 600 C.
A reaction between nitrosyl fluoride and boron is accompanied by incandescence.
Special Remarks on Explosion Hazards:
Fine dust dispersed in air in sufficient concentrations, and in the presences of an ignition source is a potential dust explosion hazard. Silver fluoride reacts explosively Boron at ordinary temperatures.
Section 6: Accidental Release Measures
Small Spill: Use appropriate tools to put the spilled solid in a convenient waste disposal container.
Large Spill:
Flammable solid.
Stop leak if without risk. Do not touch spilled material. Use water spray curtain to divert vapor drift. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources. Call for assistance on disposal.
Section 7: Handling and Storage
Precautions:
Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not ingest. Do not breathe dust. Wear suitable protective clothing. If ingested, seek medical advice immediately and show the container or the label. Keep away from incompatibles such as oxidizing agents, acids.
Storage:
Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed until ready for use. Avoid all possible sources of ignition (spark or flame).
Section 8: Exposure Controls/Personal Protection
Engineering Controls:
Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit.
Personal Protection: Safety glasses. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.
