colorless liquid, irritating odor; vapor pressure 1.33/9.6 ° C a flash point of 30 ° C; -45.8 ° C melting point; boiling point solubility of 60.1 ° C; density : the relative density (Water = 1) 0.64; the relative density (Air = 1) 2.18; Stability : unstable; risk Marker 9 (spontaneous items), 14 (organic Judaipin) the principal purpose for jet fuel, the propellant
2. The impact on the environment :
a health hazard
pathways : inhaled, ingested, percutaneous absorption.
health hazards : Acute poisoning : neurological symptoms, mainly headache, dizziness, sleepiness, ophthalmoplegia, skin hypersensitivity, followed by ataxia, muscle cramps, convulsions, the arch anti - Kok Cheung, disturbance of consciousness or mental disorder. Can neuritis and heart, liver and kidney damage. The skin and mucous membrane irritation strong, absorbed through the skin can cause poisoning. Long-term exposure can cause liver and kidney damage. Lesser damage the central nervous system.
two, toxicology information and environmental behavior
acute toxicity : LD5011.1mg/kg (internal organs of rats cavity); LC5015mg/m3, 4 hours (rat inhalation)
hazardous characteristics : exposed to the air can be spontaneous. Case open flame, heat, friction, impact caused any combustion hazards. In case of high fever can be dramatic decomposition of container rupture or explosion. With strong oxidants such as chromium anhydride, chlorate and potassium permanganate and other contacts, strong reactions will occur, cause a fire or explosion. Water and water vapor reaction and emit easily fire the explosive hydrogen.
combustion (decomposition) product : boron oxide.
3. Emergency Monitoring Methods :
4. Laboratory monitoring methods :
5. Environmental standards :
American plant health standards -108.9
6. Emergency treatment and disposal methods :
a leakage contingency
rapid withdrawal from air leakage personnel to a safe area, and immediately quarantined, a small amount of leakage isolation 300m, substantial leakage isolation of 450, and strictly limit access. Cut off the fire source. Recommended emergency personnel wearing self-Pressurized respirators to wear protective clothing. Do not direct contact with leakage. As far as possible, cut off the source of leakage. Preventing access to sewers, flood discharge trench so restrictive space. The clearance under the guidance of experts.
two protective measures
respiratory protection : homework, self-priming should wear a gas mask filter type (half-mask). When necessary, wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
physical protection : wear protective overalls on infiltration.
hand protection : Wear rubber gloves.
other : work site prohibit smoking, eating and drinking. Work to complete, thorough cleansing. Separate storage of toxic pollution by the clothes, washed standby. Workshops should be equipped with first aid equipment and medicines. Workers should learn how to help themselves and mutual aid.
three, and emergency measures
contact with the skin : immediately stripped of contaminated clothing, immediately with 1% -3% triethanolamine or 3% aqueous ammonia rinse, at least five minutes, and then soap and water thoroughly washed. Medical treatment.
eye contact : immediately filed eyelid, with a large number of mobile water or saline thoroughly washed at least 15 minutes. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. If breathing is difficult, give oxygen. If breathing stop immediately mouth. Medical treatment. Fresh into
: warm water to drink enough, the symptoms and to seek medical treatment.
fire fighting methods : fire-extinguishing agent : Dry, dry sand, carbon dioxide. Ban water or foam.
