2. Environmental Information
1. Potential Health Hazards
Effects health via: ingestion, inhalation, skin contact.
Hazards: causes central nervous system depression. First characterized by
excitement, followed by depression.
Acute toxicosis: Mostly because been swallowed. Normally there are four stages
as excitement, drownsiness, coma and respiratory failure. Third and forth stages
may cause unconsciousness, collapse, coma, then death due to angiocarpy and
Chronic: Prolonged exposure to high concentrations may cause irritation to eyes
and respiratory tract. May cause nervous system effects characterized by headache,
dizziness, unconsciousness coma and nausea, also causes liver and alimentary
tract damage Prolonged or repeated skin contact may cause defatting and
2. Toxicological and Environmental Information
Toxicity: tiny toxic
Oral, Rabbit: LD50 7060mg/kg
Skin, Rabbit: LD50 7340mg/kg
2Inhalation, Rat: LC50 37620mg/m/10H
Draize test, rabbit, eye: 500 mg Severe;
Draize test, rabbit, skin: 15 mg/24H Moderate;
Subacute and chronic: Oral, Rat:10.2g/kg/day, 12 weeks, lost weight, with fatty liver
Reproductive toxicity？ Oral, Rat TDLo？7.5g/kg(9days pregnant)；teratogenicity
Carcinogenicity ？Oral, Mouse TDLo？340mg/kg (57weeks；discontinuous)；
Fire Risk: Flammable liquid and vapor. Vapors may form an explosive mixture with air. Containers may explode in the heat of a fire. May form explosive peroxides. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Also may travel to a source of ignition and flash back.
Decomposition Products: Carbon monoxide, carbon dioxide.

5. Environmental standard
Former Soviet Union Standard: Max. concentration of harmful substance in air in
3workshop below 1000mg/m.
3Former Soviet Union Standard(1977): Atmosphere quality standard0.5mg/m.
Olfaction threshold concentration 50ppm.
6. Emergency measures
a. Accidental release measures
Evaluate everyone to safe place, away from spilling and leaking. Remove
all sources of ignition. For emergency or engineering handling, wear a
self-contained breathing apparatus in pressure-demand, and full protective
gear. Absorb spill with inert material (e.g. vermiculite, sand or earth), then
place in suitable container. A vapor suppressing foam may be used to
b. Personal Protective Equipment
Respiratory tract: need not particular protection, to avoid inhalation of
high concentrations, wear a filtering respirator or chemical safety goggles.
Eyes: need not particular protection.
Clothing: anti-static workwear.
Skin(hands): wear regular protective gloves to prevent skin exposure.
Additional: no smoking during handling process or in storage c. First Aid Measures
Skin contact: remove contaminated clothing and shoes, flush skin with plenty of water.
Eye contact: lifting the upper and lower eyelids. flush eyes with plenty of water or physiological saline .Get medical aid immediately.
Inhalation: Remove from exposure to fresh air immediately. Get medical aid immediately.
Ingestion: give enough warm water, and induce vomiting. Get medical aid. d. Fire Fighting Measures: move more containers to safe places if possible. Use water spray to cool fire-exposed containers until well after fire is out. Extinguishing Media: dry chemical, alcohol-resistant foam, carbon dioxide, sand.
