colorless, odorless gas; vapor pressure 1.79mPa/25 ° C -137 ° C melting point; boiling point -55 ° C; solubility : soluble in ethanol, benzene, carbon tetrachloride; density : relative density (water = 1) 1.7 (liquid); the relative density (Air = 1) 3.5; Stability : stability; risk Marker 6 (toxic gas); the main purposes : reagents for the analysis, pharmaceuticals, dyes, pesticides and fumigants ingredients

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : the eyes, skin and mucous have a strong stimulating effect. May cause nausea, vomiting, abdominal pain, symptoms such as itchy skin.

two, toxicology information and environmental behavior

toxicity : Medium toxic to humans and animals.
acute toxicity : LD₅₀100mg/kg (guinea pigs by mouth)
hazardous characteristics : react with water or steam heat emit toxic corrosive gases. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : sulfur oxides, hydrogen fluoride.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography

5. Environmental standards :
American plant health standards 20mg/m3

6. Emergency treatment and disposal methods :
a leakage contingency

rapid withdrawal of staff from air leakage supremacy wind, and isolated until the gas dissipated, the emergency personnel to wear positive pressure self-contained breathing apparatus to wear chemical protective clothing. Cut off the fire source. To ensure the safety of plugging. Water spray-volatile slow (or spread), but not to spill or leak water directly point. Discharge (indoor), or powerful ventilation (outdoor). Reusable containers can leak, but to go through treatment to remove the remaining gas potential.

two protective measures

respiratory protection : concentration in air overweight, they should wear protective masks. Emergency rescue or evacuation, wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
physical protection : 52,400 to wear protective clothing.
hand protection : Wear gloves against chemicals.
other : no smoking scene work. To maintain good health habits.

three, and emergency measures

contact with the skin : the pollution off clothing, mobile water rinse.
eye contact : immediately open from top to bottom eyelid, mobile water rinse for 15 minutes for medical treatment.
INHALED : from the scene to fresh air. Difficult to breathe oxygen. Stop breathing, artificial resuscitation immediately. Medical treatment.

fire fighting methods : cut off of gas supply. Cooling water containers, if possible to move containers from the scene empty Department.
