Hazards and protection.
Storage Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible
substances. Store protected from moisture.
Handling Wash thoroughly after handling. Remove contaminated clothing and wash
before reuse. Minimize dust generation and accumulation. Avoid contact with
eyes, skin, and clothing. Do not breathe dust, vapor, mist, or gas. Keep
container tightly closed.
Do not ingest or inhale. Use only in a chemical fume hood.
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 A respiratory protection program that meets OSHA's 29 CFR 1910.134
and ANSI Z88.2 requirements or European Standard EN 149 must be followed
whenever workplace conditions warrant a respirator's use.
Small spills or leaks Avoid runoff into storm sewers and ditches which lead to
waterways. Clean up spills immediately, using the appropriate protective
equipment. Scoop up with a nonsparking tool, then place into a suitable
container for disposal.
Avoid generating dusty conditions. Remove all sources of ignition.
Stability Stable at room temperature in closed containers under normal storage
and handling conditions. Volatile in steam.
Incompatibilities Oxidizing agents, chromium trioxide, chromic anhydride,
dinitrogen pentaoxide, mineral acids, moisture, stong alkalies, alumiunum
chloride + benzoyl chloride.
Hazardous Decomposition Carbon monoxide, irritating and toxic fumes and gases,
carbon dioxide.
