molecular 48.1

colorless flammable gas; boiling point -37.7 ° C; melting point -143.2 ° C; dissolved Solution : soluble in alcohol, ether, water-soluble; density : relative density (water = 1) 0.82 (-37.7 ° C); the relative density (Air = 1) 1.66; Stability : stability; risk Marker 4 (flammable gas); the main purpose

2. The impact on the environment :
a health hazard

pathways : inhalation.
health hazards : a narcotic goods. Heating decomposition, releasing highly toxic hydrogen fluoride gas.

two, toxicology information and environmental behavior

hazardous characteristics : air mixture can form explosive mixtures. Case open flame, heat or contact with oxidants, combustion caused a risk of 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 :
portable gas chromatography

4. Laboratory monitoring methods : gas chromatography

5. Environmental standards :

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. Using industrial coating or adsorption / absorbent cover near the leaking sewer, and other gases to prevent access. A reasonable ventilation, accelerated proliferation. Leak containers should be properly handled, repair, testing later use.

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 : when necessary, wearing chemical protective 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, foam, dry powder.
