Hazards and Protection.
Storage Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from metals. Keep containers tightly closed. Do not store in aluminum containers.
WHMIS Insufficient information
Handling Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with skin and eyes. Avoid ingestion and inhalation.
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 gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Respirators 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.
Small spills/leaks Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation.
Disposal code 2
Stability Stable under normal temperatures and pressures.
Incompatibilities Incompatible with alkali or alkaline earth metals such as sodium,potassium, aluminum, barium, lithium, samarium, sodium-potassium alloy, titanium, zinc, magnesium, and beryllium.
Decomposition Hydrogen chloride, phosgene, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, hydrogen fluoride.

Fire.
Autoignition, °C 680
Fire fighting 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. Vapors may be flammable in vessels of adequate size. Extinguishing media: For small fires, use water spray, dry chemical, carbon dioxide or chemical foam. Use extinguishing media most appropriate for the surrounding fire. Cool containers with flooding quantities of water until well after fire is out.

Health.
Poison_Class 5
Exposure effects Prolonged or repeated skin contact may cause defatting and dermatitis.
   Ingestion Ingestion of large amounts may cause gastrointestinal irritation. Expected to be a low ingestion hazard.
   Inhalation Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Vapor reduces oxygen available for breathing. May cause respiratory tract irritation. May cause heart disturbances, possibly leading to cardiac arrest and death. May cause narcotic effects in high concentration.
   Skin May cause skin irritation. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis.
   Eyes Contact produces irritation, tearing, and burning pain. May cause conjunctivitis.

First aid
 
   Ingestion Do NOT induce vomiting. 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.
   Inhalation Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
   Skin 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.
   Eyes Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
