Hazards and Protection.
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Storage under a nitrogen blanket has been recommended.
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not get on skin or in 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.
Wear a self contained breathing apparatus and appropriate Personal protection. (See Exposure Controls, Personal Protection section). Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Carefully scoop up and place into appropriate disposal container.
Stable at room temperature in closed containers under normal storage and handling conditions.
Metals (aluminum, magnesium, zinc, calcium, sodium, and potassium), strong alkalis, strong oxidizing agents, liquid ammonia, light.
Carbon monoxide, carbon dioxide, hydrogen bromide.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Substance is noncombustible. Extinguishing media: Use extinguishing media most appropriate for the surrounding fire.
Contact with metals may evolve flammable hydrogen gas.
Decomposition gases are toxic and irritating.

May cause fetal effects. May cause cancer in humans.
Harmful if swallowed. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause systemic toxicity with acidosis. May cause effects similar to those for inhalation exposure.
Effects may be delayed. Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Irritation may lead to chemical pneumonitis and pulmonary edema. May cause liver and kidney damage. May cause heart disturbances, possibly leading to cardiac arrest and death. May cause lung damage.
Causes severe skin irritation. Harmful if absorbed through the skin. May cause skin burns.
Causes severe eye irritation. May result in corneal injury.
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. Get medical aid.
Get medical aid. 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.
