Hazards and Protection.
Store in a cool, dry, well-ventilated area away from incompatible substances. Do not store in metal containers. Keep containers tightly closed. Store protected from moisture.
Wash hands before eating. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Wash clothing before reuse. Discard contaminated shoes.
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 a chemical apron. Wear butyl rubber gloves, apron, and/or clothing. Clothing: Wear a chemical apron. Wear butyl rubber gloves, apron, and/or clothing.
Wear a NIOSH/MSHA or European Standard EN 149 approved full-facepiece airline respirator in the positive pressure mode with emergency escape provisions.
Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation. Do not get water inside containers.
Stable under normal temperatures and pressures.
Bases - amines - alcohols - moist air or water.
Hydrogen chloride, 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. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Contact with metals may evolve flammable hydrogen gas. Extinguishing media: Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out.
Combustible material: may burn but does not ignite readily.
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.
Irritating hydrogen chloride may form.
TLV: 0.05 ppm; 0.32 mg/m3 (ACGIH 1993-1994). OSHA PEL: TWA 0.3 mg/m3 (0.05 ppm) NIOSH REL: TWA 0.3 mg/m3 (0.05 ppm) NIOSH IDLH: 15 mg/m3
Agitation and syncope, both attributed to panic, have been reported.
May be fatal if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
May cause respiratory tract irritation. Inhalation may produce coughing, nausea, and pulmonary edema. In rare instances, exposure may cause sensitization, resulting in inflammation of the mucous membranes and in eczematous eruptions.
May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Causes redness and pain. Causes skin irritation and possible burns.
Lachrymator. Causes eye irritation and possible burns. May cause reversible inflammation and corneal injury with opacity.
Never give anything by mouth to an unconscious person. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. Get medical aid if irritation or symptoms occur.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear. DO NOT use mouth-to-mouth respiration.
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. Destroy contaminated shoes.
If irritation develops, get medical aid. Extensive irrigation is required (at least 30 minutes).
