molecular 46.07

colorless gas, ethers unique odor; vapor pressure 533.2kPa/20 ° C -41 flash point ° C melting point -141.5 ° C; boiling point -23.7 ° C; solubility : soluble in water, alcohol, ether; density : relative density (water = 1) 0.66; the relative density (Air = 1) 1.62; Stability : stability hazard markers 4 (flammable gases); the main purposes : as a refrigerant, solvent extraction agent, a catalyst and polymer stabilizers

2. The impact on the environment :
a health hazard

pathways : inhalation.
health hazards : on the central nervous system is a disincentive to weak anesthetic effects. Inhalation can cause anesthesia, suffocation flu. Right skin irritation.

two, toxicology information and environmental behavior

toxicity : a weak anesthetic, respiratory and skin stimulation.
acute toxicity : LC₅₀308000mg/m3 (rat inhalation); Inhalation 154.24g/m3 × 30 points, the mildly narcotic.

hazardous characteristics : flammable gas. Mixed with the air can form explosive mixtures. Contact heat, sparks or flame easy oxidizer combustion explosion. In contact with air or light conditions can be generated with a potential explosion risk of peroxides. Gas is heavier than air, will spread to the lower Department of considerable local and met the fire will generate a return to burning. In case of high fever, increased pressure within containers, cracking and the risk of explosion.
combustion (decomposition) products : carbon monoxide, carbon dioxide.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industry publishers

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. As far as possible, cut off the source of leakage. Using industrial coating or adsorption / absorbent cover near the leaking sewer, and other gases to prevent access. A reasonable ventilation, accelerated proliferation. Spray - diluted solution. To build a causeway or trenching asylum produce a lot of wastewater. 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 : Most do not need special protection, but suggested that under special circumstances, wearing chemical protective safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear protective gloves general operations.
other : no smoking scene work. 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 : 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, anti-insoluble bubble, dry powder, carbon dioxide, sand.
