white loose powder or crystal pieces, when placed into gray; vapor pressure; melting point; solubility : insoluble hydrocarbons, soluble ether; density : relative density (water = 1) 0.92; Stability : stability; risk Marker 10 (flammable wetlands case goods); the main purposes : for polymerization catalyst reductant, jet fuel, also used synthetic drugs

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : the right goods mucosa, upper respiratory tract, eyes and skin irritation strong. After inhaling, because the larynx and bronchial spasm, inflammation, edema, chemical pneumonia or pulmonary edema and death. Contacted after the burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

two, toxicology information and environmental behavior

hazardous characteristics : heated to 125 ° C out that the decomposition of metal hydride and lithium aluminum, and produce hydrogen. Grind in the air when ignited. Humidity and heat or water, alcohols, acids contacts that occurred exothermic reaction and release hydrogen and combustion or explosion. Contact with strong oxidants fierce reaction to explode.
combustion (decomposition) product : alumina, water.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
AAS

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing respirators-positive pressure self-sufficiency, wearing fire protective clothing. Do not direct contact with leakage. A small leak : to avoid dust, the use of non-spark tools in a dry, clean, covered containers. Transfer to a safe place. Large Leak : plastic sheeting, canvas cover and reduce dispersion. With the technology sector linkages, and to determine methods to remove.

two protective measures

respiratory protection : possible exposure to poison, they should wear headgear electric powered air-purifying respirators and dust. When necessary, proposals to wear self-contained breathing apparatus.
eye protection : Respiratory Protection has been protective.
physical protection : wear chemical protective clothing.
hand protection : Wear rubber gloves.
other : no smoking scene work. Work to complete, take a shower. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : immediately stripped of contaminated clothing, with a large number of mobile wash, at least 15 minutes. 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
: oral intake of water were found to blues or egg white. Medical treatment.

fire fighting methods : not water, foam, carbon dioxide, halocarbons (1211 extinguishing agents) fire. Only metal lid or dry graphite powder dry dolomite suffocation put out the fire.
