Exposure Controls/Personal Protection

Personal Protection
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. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Exposure Effects
May cause cancer in humans.
Exposure limit(s)
0.01 mg/m3 TLV

Fire Fighting Measures

Flash Point
205
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Oxidizer. Greatly increases the burning rate of combustible materials. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam.
Fire Potential
These substances will accelerate burning when involved in a fire.

Accidental Release Measures

Small spills/leaks
Vacuum or sweep up material and place into a suitable disposal container.

Stability and Reactivity

Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong acids - strong reducing agents - alcohols.
Decomposition
Hydrogen chloride, nitrogen oxides, carbon monoxide, carbon dioxide.
Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
