Not Applicable
Not established
Dry powder type agents specifically designed for metal powder fires.
Do not apply water to burning material. Full emergency equipment with
self-contained breathing apparatus must be worn by firefighters. During a
fire, irritating and toxic gases and aerosols may be generated by thermal
decomposition and combustion.
This product consists of pieces of metal. Dust and fumes generated from
this product (through grinding, cutting, sawing, welding, sanding, etc.) may
be a fire and explosion hazard when exposed to high temperatures or
ignition sources. particle size and dispersion in air determine reactivity.

EMPLOYEE PROTECTION RECOMMENDATIONS
HAZARD CLASS OR DIVISION:
http://www.rembar.com/MSDSni.htm
Safety glasses with side shields or goggles are recommended.
Chemically resistant gloves and clothing are recommended to minimize
skin contact. Employees should wash their hands and face before
eating, drinking or using tobacco products.
Work ambient concentrations should be monitored and if the
recommended exposure limit is exceeded, a NIOSH/MSHA approved
dust respirator should be worn.
Use local exhaust ventilation adequate to keep exposure levels below
the TLV for nuisance dust.
Emergency showers and eye wash stations should be available.
Educate and train employees in the safe use and handling of this
product.
SPILL & LEAK PROCEDURES
Utilize recommended protective clothing and equipment. Spills should be
swept up and placed in containers. Avoid generation of dust. If dust is
generated, use appropriate respiratory protection. Spill area can be washed
with water. Collect wash water for approved disposal. Keep from entering
water or ground water.
May be reclaimed or sold for scrap. Disposal must be in compliance with
federal, state and local environmental control regulations.
SPECIAL PRECAUTIONS & STORAGE DATA
