Toxicity and protection
|
Toxicity: Low toxicity. Acute toxicity: LD508.0～15.3g/kg (mouse oral); 5.9～13.4g/kg (rat oral); 1.4ml/kg (human oral, lethal) subacute and chronic toxicity: rat Corneal opacity and blindness in 2/15 animals after inhalation of 12 mg/m3 (multiple consecutive times); short-term fainting occurred in 9/28 people who inhaled 40% ethylene glycol mixture; human inhaled 40% ethylene glycol mixture heated to 105 °C Repeated inhalation of 14/38 human nystagmus, 5/38 lymphocytosis. Hazardous characteristics: In case of fire, high heat or contact with oxidizing agents, there is a danger of fire and explosion. In case of high heat, the internal pressure of the container increases, posing a risk of cracking and explosion. Combustion (decomposition) products: carbon monoxide, carbon dioxide, water. | ||
