2. The impact on the environment :
the substance of the environmental hazards, the body of water can cause pollution, the importance of the human food chain, especially in aquatic organisms occurred bioaccumulative. The substance of atmospheric ozone extremely damaging.

a health hazard

pathways : inhalation.
health hazards : high concentrations can induce cardiac arrhythmia and inhibition appointed respiratory function. For aerosol sprays, are found asthma cases of sudden death in the report. On the chronic effects not been reported.

two, toxicology information and environmental behavior

toxicity : low toxicity category is a weak anesthetic.
acute toxicity : LC₅₀10pph 1 / 2 hours (mice inhaled); LC50517g/m3, 30 minutes (small / rat inhalation); Inhalation of 5%, eye irritation, dizziness.
hazardous characteristics : Unburning. Decomposition by high fever and emit toxic fluoride and chloride gas. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide, hydrogen fluoride, hydrogen chloride.

3. Emergency Monitoring Methods :
Instrumental

4. Laboratory monitoring methods :
monitoring methods source categories
GC "urban and industrial wastewater analysis of organic compounds," such as Wang translated tenable wastewater
GC;
Chromatography / Mass Spectrometry "Solid Waste Assessment Test and Analysis Handbook" China Environmental Monitoring terminus translated solid waste
chromatography / mass spectrometry method of France and American EPA524.2
air quality : samples of activated carbon adsorption, carbon disulfide cleared, and then analyzed by gas chromatography (NIOSH)

5. Environmental standards :
former Soviet air workshop harmful substances maximum allowable concentration 1000mg/m3
olfactory threshold concentration 5.0ppm

6. Emergency treatment and disposal methods :
a leakage contingency

rapid withdrawal of staff from air leakage supremacy wind and isolation and strict restrictions on access. Cut off the fire source. Recommended emergency personnel wearing respirators-positive pressure self-sufficiency, wearing overalls general operations. As far as possible, cut off the source of leakage. A reasonable ventilation, accelerated proliferation. If possible, use immediately. Leak containers should be properly handled, repair, testing later use.
waste disposal methods : Proposed burning law. Waste and other fuel mix burning, burning to the full, to prevent the formation of phosgene. Incinerators emit hydrogen halide through scrubbers to remove.

two protective measures

respiratory protection : Most do not need special protection, high concentrations can wear contact since suction filtered gas masks (half-mask).
eye protection : Most do not need special protection, when necessary, wearing chemical protective safety glasses.
physical protection : general operating wear uniforms.
hand protection : Wear latex gloves.
other : no smoking scene work. Pay attention to personal hygiene. Enter cans, or other restrictive space of high concentration operations, someone custody.

three, and emergency measures

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.

fire fighting methods : This Unburning. Cut off the gas source. Cooling water containers, if possible to move containers from the scene empty Department.
