microstrip odor of flammable gases; Boiling Point 4. 7 ° C; -117 ° C melting point; solubility : not soluble in water; density : relative density (Air = 1) 2.9; Stability : stability; risk Marker 4 (flammable gases); the main purposes : as a refrigerant

2. The impact on the environment :
a health hazard

pathways : inhalation.
health hazards : This is a high concentration of narcotic. Heating decomposition of hydrogen fluoride release toxic fumes.

two, toxicology information and environmental behavior

toxicity : is low toxicity category. With anesthetic effects.
hazardous characteristics : air mixture can form explosive mixtures. Contact heat, Mars, easy flame burning explosion. Thermal decomposition of the release of toxic fluoride gas. Gas is heavier than air, will spread to the lower Department of considerable local and met the fire will generate a return to burning.
combustion (decomposition) products : carbon monoxide, carbon dioxide, hydrogen fluoride.

3. Emergency Monitoring Methods :
Instrumental

4. Laboratory monitoring methods : gas chromatography

5. Environmental standards :
former Soviet plant health standards 3000mg/m3

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 fire protective clothing. As far as possible, cut off the source of leakage. A reasonable ventilation, accelerated proliferation. Without risk, in situ combustion, while spray from the surrounding water cooling to prevent other combustibles on fire. Or pipeline leading to the furnace, Au to burn it. Leak containers should be properly handled, repair, testing later use.

two protective measures

respiratory protection : higher concentration in air, should treat pollution gas concentrations and the level of operating environments to choose whether hypoxia since suction filtered gas masks (half-mask) or air respirators.
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear protective gloves general operations.
other : no smoking scene work. To avoid high concentrations of respirable.

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 : cut off of gas supply. If not immediately cut off the gas supply, it is not extinguished combustion gases. Cooling water containers, if possible to move containers from the scene empty Department. Extinguishant : mist of water, carbon dioxide.
