white or blue gray translucent crystalline or powder, which can easily deliquescence; the boiling point of 850 ° C (decomposition); melting point 680 ° C; solubility : not soluble in benzene, toluene, ether-soluble; density : relative density (water = 1) 0.82; Stability : unstable; risk Marker 10 (Yi met wetlands Burning goods); the main purposes : as desiccant, organic synthesis of condensing agent, nuclear materials and protective agent such as

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : Mucocutaneous a strong stimulus and corrosion. After inhaling caused sneeze, cough, dyspnea, bronchitis. Can cause nasal septum perforation. Eye contact can be induced conjunctivitis or burns. Skin burns can be addressed. There oral poisoning weakness, dizziness, blurred vision, nausea, vomiting, severe wrong crowds, convulsion or mental disorders.

two, toxicology information and environmental behavior

hazardous characteristics : high chemical reactivity, exposure to air can spontaneous combustion. Heat and humidity or, acids that contact with the hydrogen emit heat and cause a fire and explosion. With a strong oxidant can react, cause a fire or explosion. Case Humidity and water generation hydroxide, a strong corrosive.
combustion (decomposition) products : lithium oxide, water.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
measured in the air : the filter used to collect samples, and then AAS analysis (NIOSH)
GC, in the light "Manual of Analytical Chemistry" (4th the separation, chromatography analysis), the chemical industry publishers

5. Environmental standards :
American plant health standards 0.025mg/m3

6. Emergency treatment and disposal methods :
a leakage contingency

isolation leak contaminated areas, restricting access. Cut off the fire source. Recommended emergency personnel wearing self-absorption filter respirators, wearing anti-acid dress. 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. Waste treatment : wastes mixed with sand, sprayed with alcohol and then spray water, and after the water will dilute discharged into the sewer.

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 : Polyethylene wear protective clothing.
hand protection : Wear rubber gloves.
other : no smoking scene work. Work to complete, take a shower. To maintain good health habits.

three, and emergency measures

contact with the skin : immediately stripped of contaminated clothing, diligent .5% -3% sodium gastric lavage, catharsis. 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. Sodium chloride can be taken. 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.
