colorless liquid smoke, irritating odor; 20.0kPa vapor pressure (20 ° C); the temperature -12 ° C; Boiling Point 63 ° C solubility : soluble ether, benzene, chloroform; density : relative density (water = 1) 1.49; the relative density (Air = 1) 4.4; Stability : stability; risk Marker 20 (corrosive acid); the main purposes : Preparation for organic chloride, but also for the production of military gas

2. The impact on the environment :
a health hazard

pathways : inhaled, ingested.
health hazards : strong irritant, can cause skin and mucous serious burns. A small amount inhaled, cause loss of appetite, emerging after coughing, difficulty in breathing, fatigue, diarrhea, vomiting, headache, asthma, vision loss, etc..

two, toxicology information and environmental behavior

hazardous characteristics : heating water or other heat liberation and emit toxic corrosive flue gas. In case of high fever can be dramatic decomposition of container rupture or explosion. With strong corrosive.
combustion (decomposition) products : carbon monoxide, carbon dioxide, phosgene.

3. Emergency Monitoring Methods :

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

leak contaminated areas evacuated personnel to a safe area, not to prohibit access to the contaminated area, cut off the source of fire. Recommended emergency personnel wearing self-contained breathing apparatus to wear chemical protective clothing. Do not direct contact with leakage, in ensuring the safety of plugging. Use sand, dry lime or soda ash mixture, then collect and transport the waste to disposal sites. We could also use non-flammable dispersant wash made of latex, Add Water dilution of the wastewater system. Large Leak : Dike asylum, and then to collect, transfer, recycling or waste processed sound.

two protective measures

respiratory protection : its possible exposure to vapor or smoke, wear gas masks or gas-helmet. Emergency rescue or escape, it is recommended to wear self-contained breathing apparatus.
eye protection : Wear protective chemical safety glasses.
protective clothing : wearing overalls (anti-corrosion material).
hand protection : Wear rubber gloves.
other : work, take a shower. Separate storage of toxic pollution by the clothes, washed reuse. To maintain good health habits.

three, and emergency measures

contact with the skin : contaminated clothing off with soap and water thoroughly washed. If it burns, medical care treatment.
eye contact : immediately filed eyelid, mobile or saline irrigation water for at least 15 minutes. Medical treatment.
Inhalation : rapidly from the scene to fresh air. To keep the airway patency. When necessary, respirators. Medical treatment. Fresh into
: patients immediately clear when the mouthwash, or egg white to the blues. Medical treatment.

fire fighting methods : dry powder, sand, carbon dioxide. Ban water.
