white to light gray nuances of crystallization, 25% -50% ratio scattered in the oil; boiling point decomposition; the temperature of 800 ° C / decomposition; solubility : not soluble in liquid ammonia, benzene, carbon disulfide, the melting of sodium hydroxide; density : relative density (water = 1) 0.92; Stability : Unstable ; risk Marker 10 (case of wet flammable substances); the main purposes : for condensing agent, alkylating agent and reducing agent such as

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : ocular and respiratory irritant, skin burns caused direct contact. Coverage digestive tract caused burns.

two, toxicology information and environmental behavior

hazardous characteristics : high chemical reactivity, moist air can be spontaneous. 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 : the oxidation of sodium and 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 self-contained breathing apparatus to wear anti-acid dress. 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 : Polyethylene wear 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 : not water, foam, carbon dioxide, halocarbons (1211 extinguishing agents) fire. Only metal lid or dry graphite powder dry dolomite suffocation put out the fire.
