Hazards and Protection.
Keep away from heat and flame. Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.
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.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Provide ventilation.
Stable under normal temperatures and pressures.

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, dry chemical, chemical foam, or alcohol-resistant foam.
This chemical is combustible.
Containers may explode when heated.
Fire may produce irritating, corrosive and/or toxic gases.
TLV (for vapor): 1 ppm; 7 mg/m3 (as TWA) 2 ppm; 14 mg/m3 (STEL) (ACGIH 1997). OSHA PEL: TWA 1 ppm (7 mg/m3) NIOSH REL: TWA 1 ppm (7 mg/m3) NIOSH IDLH: 100 ppm
May cause liver and kidney damage. Prolonged or repeated exposure may cause thyroid damage. Repeated exposure may cause damage to the spleen.
Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause liver and kidney damage.
Causes respiratory tract irritation.
Causes skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis.
Causes eye irritation.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse.
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
