colorless liquid, a benzene-like odor; vapor pressure 19.92kPa/39.4 ° C flash point : -15 ° C; melting point - 41.9 ° C; boiling point of 82.8 ° C ; solubility : do not dissolve in water, immiscible in ethanol, ethyl ether, acetone, benzene; density : relative density (water = 1) 1.03; the relative density (Air = 1) 3.31; Stability : stability; risk Marker 7 (flammable liquids ); the main purposes : for the killing, killing eggs agents for plastics and polymers tree refers to the identification

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, its toxic effects can be similar to benzene.

two, toxicology information and environmental behavior

acute toxicity : LD₅₀4399mg/kg (rat oral); LC₅₀26908mg/kg (rat inhalation)
hazardous characteristics : flammable the event of fire, heat or contact with oxidants, combustion caused a 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, hydrogen fluoride.

3. Emergency Monitoring Methods :

4. Laboratory monitoring methods :
chromatography / mass spectrometry (refer to EPA 524.2)
gas chromatography, reference to "Manual 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 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 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 collection devices. Recovery or shipped to the disposal of waste disposal sites.

two protective measures

respiratory protection : concentration in air overweight, self-priming should wear a gas mask filter type (half-mask). Emergency rescue or evacuation, air respirator should wear respirators or oxygen.
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.
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 to maintain the scene. Try 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.
