Hazards and Protection.
Store in a cool, dry place. Store in a tightly closed container.
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 skin and eyes. 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.
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.
Vacuum or sweep up material and place into a suitable disposal container. Reduce airborne dust and prevent scattering by moistening with water. Clean up spills immediately, using the appropriate protective equipment.
Stable under normal temperatures and pressures.
Oxidizing agents, reducing agents, and strong bases.
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, 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. Extinguishing media: Use foam, dry chemical, or carbon dioxide.
Slightly flammable. Combustible, often explosive.
Fire may produce irritating, corrosive and/or toxic gases.
TLV: 0.15 ppm; 1.0 mg/m3 (as TWA) (skin) (ACGIH 1991-1992). OSHA PEL: TWA 1 mg/m3 skin NIOSH REL: TWA 1 mg/m3 skin NIOSH IDLH: 50 mg/m3
May cause liver and kidney damage. May cause cancer according to animal studies. May cause reproductive and fetal effects.
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause systemic toxicity with acidosis. May cause liver and kidney damage. May cause cyanosis.
Causes respiratory tract irritation. May cause effects similar to those described for ingestion.
Causes severe skin irritation. Absorption into the body may cause cyanosis.
Causes severe eye irritation. May cause eye injury. Effects may be delayed.
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 immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
