Hazards and Protection.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from light.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Store protected from light.
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.
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.
Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.
Stable at room temperature in closed containers under normal storage and handling conditions. May decompose when exposed to light.
Oxidizing agents, reducing agents, bases, direct light.
Carbon monoxide, carbon dioxide.

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Contact with metals may evolve flammable hydrogen gas.
Fire may produce irritating, corrosive and/or toxic gases.
Effects may be delayed.
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May be harmful if swallowed.
Causes respiratory tract irritation. Can produce delayed pulmonary edema.
Causes moderate skin irritation.
Causes eye irritation. May cause chemical conjunctivitis.
Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do not use mouth-to-mouth respiration if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
