2、Environmental Impact

2.1 Health hazard

Invasive ways: inhalation, ingestion, percutaneous absorption.

Health hazards: poisoning manifestations of recurrent syncope and can be inhaled, nystagmus, lymphocytosis. Acute poisoning after oral administration is divided into three stages: :the first stage is the main symptoms of central nerve system, mild like ethanol poisoning, severe rapidly produce convulsions, coma, and finally died,In the second stage, the heart and lung symptoms were obvious, severe cases can have pulmonary edema, bronchial pneumonia,the third stage was mainly manifested in different degrees of renal failure.An oral lethal dose estimation is 1.4 ml/k(1.56g/kg)。

2.2 Toxicology information and environmental behavior

Toxicity: belong to low toxicity.

Acute toxicity: LD508.0 ~ 15.3g/kg (mice);5.9 ~ 13.4g/kg (rat);1.4ml / kg (person orally, death)

Subacute and chronic toxicity: rats inhaled 12 mg/m3 (continuous) 2/15 animal corneal opacity, blindness after eight days;Inhaled 40% glycol mixture 9/28 people appear black-out;Inhaled 40% glycol mixture is heated to 105 ℃,Repeated inhalation,14/38 people nystagmus, 5/38 people lymphocytes increased

Dangerous features:contact with open flame, high fever and antioxidant,There is a risk of causing burning explosion。If encounter high fever, container pressure increase, is in danger of cracking and explosion.

Combustion (decomposition) products: carbon monoxide, carbon dioxide.

3、Environmental Standards

The maximum allowable concentrations of harmful organisms in water: 1.0 mg/L

Smell concentration: 90 mg/m3

4、Emergency disposal method

4.1 Leakage emergency treatment

Cut off the fire, wear self-contained breathing apparatus and general fire protective clothing.Do not directly contact with leakage,Plugging in ensuring safety situation,Rinse with plenty of water, dilute solution into the wastewater system.If large spills, asylum with a causeway,then to collect, transfer, recycling or abandoned after a harmless treatment。

4.2 Protective measures

Respiratory protection: generally don't need special protection, high concentration of contact can wear self-contained breathing apparatus.

Eye protection: Wear safety glasses when necessary.

Protective clothing: wear overalls.

Hand protection: if necessary, wearing anti-chemical gloves.

Other: after work, take a shower and change clothes. To avoid repeated contact for a long time. Regular physical examination.

4.3 Emergency treatment

Skin contact: remove contaminated clothing, wash with the flow of water.

Eye contact: immediately opened the upper and lower eyelids, irrigate with flowing water for 15 minutes.

Inhalation: quickly from the scene to the fresh air, immediately seek medical treatment.

Eating:washing stomach with plenty of water or soda water,then seek medical advice,if the people eat.

Fire extinguishing method: mist water,foam, carbon dioxide, dry powder, sand.
