Toxicological data and environmental behavior:
Acute toxicity: LD504000mg/kg (rat oral); 13500mg/kg (rabbit skin)
Hazardous characteristics: Its vapor and air form an explosive mixture, which can cause combustion and explosion when exposed to open fire and high heat. It reacts strongly with oxidants. Its vapor is heavier than air and can diffuse to a considerable distance at a lower level. It will cause a burn when exposed to open fire.
Combustion (decomposition) products: carbon monoxide, carbon dioxide.
Leakage emergency treatment:
Evacuating personnel from the leaked contaminated area to the safety zone, forbidding unrelated personnel to enter the contaminated area and cutting off the fire source. Emergency personnel wears a self-contained breathing apparatus and chemical protective clothing. Do not contact leaks directly and plug them in case of safety. Spraying water mist can reduce evaporation. It is absorbed with sand, vermiculite or other inert materials and then collected in a sealed container for marking and treatment. If a large number of leaks occur, the embankment is used to accommodate them, and then they are collected, transferred, recycled or disposed of harmlessly. Waste is treated by incineration.
Protective measures:
Respiratory protection: it is recommended to wear a gas mask when it may be exposed to vapor. A self-contained breathing apparatus should be worn in high concentration environment.
Eye protection: Wear chemical safety glasses when you may be in contact with vapor.
Physical protection: wear anti-static work clothes.
Hand protection: Wear protective gloves when exposed to a high concentration.
Others: Smoking is strictly prohibited in the workplace. Avoid long-term repeated contact. Pay attention to personal hygiene.
Emergency measures:
Skin contact: Remove contaminated clothes and rinse thoroughly with soap and water.
Eye contact: Open the upper and lower eyelids immediately and rinse them with flowing water for 15 minutes. Seek medical treatment.
