2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazard : inhalation, oral or absorbed through the skin after hazardous to health. Right skin irritation. Its vapor or mist to the eyes, mucous membrane, respiratory stimulating effects.

two, toxicology information and environmental behavior

hazardous characteristics : flammable vapor and air can form explosive mixtures. Case fire, high-heat combustion caused the explosion. With a strong oxidant can respond. In case of high fever, can occur polymerization reaction to a lot of heat and caused vessels rupture and explosion. High-speed impact, mobile, stirring after sparks from static discharge caused combustion explosion. Its vapor 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.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods : gas chromatography

5. Environmental standards :

6. Emergency treatment and disposal methods :
a leakage contingency

rapid withdrawal from air leakage personnel to a safe area, 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. Preventing access to sewers, flood discharge trench so restrictive space. A small leak : activated carbon or other inert materials to absorb. We could also use a lot of water rinse, diluted Add Water Wastewater System. Large leak : to build a causeway or trenching asylum; Foam coverage, lower vapor disasters. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : concentration in air overweight, they should wear respirators, filter type (half-mask). Emergency rescue to be evacuated, wearing air respirators, oxygen respirator.
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear latex gloves.
other : no smoking scene work. To avoid long-term repeated exposure.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin.
eye contact : Did eyelid, mobile or saline irrigation water. Medical treatment.
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. Fresh into
: warm water to drink enough, the symptoms and to seek medical treatment.

fire fighting methods : water cooling containers, if possible to move containers from the scene empty Department. At the scene of containers, if any, change from the pressure relief safety devices have voices must evacuate immediately. Extinguishant : foam, powder, CO2, sand. Water fire invalid.
