Hazards and Protection.
Separate from acids, alkalies, halogens, salts, metals, organic matter. Store in a cool, dry, well-ventilated location. Keep cylinders restrained.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Self-contained breathing apparatus, acid suit, and gloves.
Do not use water on material itself. Keep material out of water sources and sewers. Use water spray to knock-down vapors. Neutralize spilled material with crushed limestone, soda ash, or lime.
Thermostable up to 460 C; fumes in air.
Reacts with these other hydrogen-containing substances (among others) vigorously enough to cause a fire or explosion: acetic acid, ammonia, benzene, ethanol, hydrogen, hydrogen sulfide, methane, cork, grease paper, wax Mixtures with acids, halogens, metal halides, metals, nonmetals, or metal oxides at ambient or slightly above ambient temperatures have resulted in violent reaction (nitric acid, sulfuric acid, chlorine, iodine, ammonium chloride, potassium iodide, boron powder, selenium, tellurium, aluminum powder, bismuth, cobalt powder, iron powder, arsenic, nickel powder, chromium trioxide, charcoal, red phosphorus, sulfur dioxide, magnesium oxide.
Not combustible, but if involved in a fire decomposes to produce toxic gases.
Do not use water on material itself. Use dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors.
Noncombustible, but very reactive.
Containers may burst when exposed to heat of fire. It will accelerate the burning of combustible material.
Toxic and irritating fumes of hydrogen fluoride and bromine may form in fires.
TLV: 0.1 ppm; 0.72 mg/m3 (ACGIH 1991-1992).
Dyspnea, bronchospasm (with abnormal pfts and hypoxia), chemical pneumonitis, pulmonary edema (can be hemorrhagic), tracheobronchitis, upper airway obstruction, chemical burns (larynx, trachea, bronchi) and ards may occur following inhalation.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove all exposed clothing and jewelry taking necessary precautions to prevent secondary exposure to health care providers. Irrigate exposed areas promptly with copious amounts of water for at least 30 minutes. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
Immediately flush eyes with running water for at least 20 minutes.
