2. The impact on the environment :
a health hazard

pathways : inhaled, ingested, percutaneous absorption.
health hazards : anesthesia and have a stimulating effect.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀2656mg/kg (rabbit oral); Inhalation 43.5g/m3 × 1 minute, stimulating the eyes and breathing difficulties.
hazardous characteristics : flammable vapor and air can form explosive mixtures. Case fire, high-heat combustion caused the explosion. Contact with the oxidizer will be fierce response. In the scene, heating containers risk of 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
reference to the "Handbook of Analytical Chemistry" (fourth volumes, chromatography analysis), the chemical industrial Press

5. Environmental standards :
olfactory threshold concentration ME (70mg/m3)

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, prevent access to sewers, flood discharge trench so restrictive space. A small leak : sand, dry lime or soda ash mixed. 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 : its vapor may come into contact with, they should wear self-absorption filter respirators (half-mask). Emergency rescue or evacuation, it is recommended to wear air respirators.
eye protection : Wear protective chemical safety glasses.
physical protection : antistatic wear uniforms.
hand protection : Wear rubber gloves.
other : no smoking scene work. Work to complete, take a shower. Pay attention to personal hygiene.

three, and emergency measures

contact with the skin : stripped of contaminated clothing, use soap and water thoroughly washed skin. Medical treatment.
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 : Anti-insoluble foam, carbon dioxide, dry, sandy soil.
