soft silver-white metal; 0.13kPa vapor pressure (23 ° C); the temperature of 179 ° C; the boiling point 1317 ° C; solubility : insoluble hydrocarbons, dissolved in nitric acid, ammonia; density : relative density (water = 1) 0.53; Stability : unstable; risk Marker 10 ( case wet flammable substances); the main purposes : as reductive agent with hydride alloy hardening agent, copper and copper alloy Deoxidizer also used in organic synthesis

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : strong corrosive materials, eye and skin irritation or cause contact burns.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀1000mg/kg (internal organs of mice cavity)

hazardous characteristics : high chemical reactivity, heated to a molten state can be spontaneous combustion in the air, but dust can be at room temperature combustion. With water or acid reaction of hydrogen and emit heat can cause a fire. Then molten combustion logistics casual and emit white smoke and fire all covert. Lithium in air, oxygen, nitrogen or carbon dioxide combustion, in particular, it oxide lithium or lithium nitride presence burns easily. The high temperature lithium with concrete or other aqueous materials should be fierce, the reaction of hydrogen and emit air can form explosive mixtures. With halogen, sulfur, phosphorus and other dramatic chemical reactions, cause a fire.
combustion (decomposition) products : lithium oxide.

3. Emergency Monitoring Methods :

4. Laboratory Monitoring Methods : Plasma Spectrometry

AAS "water and wastewater standards test" version 15

5. Environmental standards :
the United States (1976) agricultural irrigation standards 2.5mg/L

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-contained breathing apparatus to wear protective clothing. Do not direct contact with leakage. A small leak : Income metal containers and stored in kerosene or liquid paraffin. Large Leak : with the technology sector linkages, and to determine methods to remove.

two protective measures

respiratory protection : Most do not need special protection, but suggested that under special circumstances, since wearing suction filtered respirators.
eye protection : Wear protective chemical safety glasses.
physical protection : wear chemical protective clothing.
hand protection : Wear rubber gloves.
other : no smoking scene work. 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 : ban on the use of water and a foam fire extinguishing agent or halides. Using carbon dioxide and dry powder was invalid. The best way is to use fire drying graphite powder dry sand and boredom flameout Miao, isolated from the air.
