molecular 88.10

colorless liquid, with special flavor; vapor pressure 11.3kPa/25 ° C flash point : -3 ° C; -92.9 ° C melting point; boiling point of 81.3 ° C; solubility : water-soluble and insoluble in most organic solvents; density : relative density (water = 1 ) 0.91; the relative density (Air = 1) 3.04; Stability : stability; risk Marker 7 (flash point flammable liquids); the main purposes : as organic solvents, and used in the manufacture of perfume, insecticides and fungicides fumigation

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, upper respiratory tract and mucous membrane irritant.

two, toxicology information and environmental behavior

acute toxicity : LC₅₀3980mg/kg (rat oral); 3400mg/kg (mice) are
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 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 :

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. Do not direct contact with leakage. As far as possible, cut off the source of leakage, prevent access to sewers, flood discharge trench so restrictive space. A small leak : Non-flammable dispersant made of latex, wash, lotion diluted Add to the 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 : fire-extinguishing agent : Anti-insoluble foam, carbon dioxide, dry, sandy soil.
