Environmental impact
1. Health hazards
Invasion routes include inhalation, ingestion, and transdermal absorption.
Health hazards: Irritation to eyes and skin. May be fatal if ingested, inhaled or absorbed through skin. Exposure may cause liver and kidney damage.
2. Toxicological information and environmental behavior
The toxicity is high. Acute toxicity/(rat oral) hour (rat inhalation) mouse inhalation/hour,/death (day) rat inhalation/hour,/death (~day) Subacute and chronic toxicity in rabbit periorally, and then weeks , and then weeks, liver damage occurs, and death occurs week after week. The mutagenicity test was positive for Salmonella typhimurium. Gene mutation, mammalian mouse lymphosarcoma cell positive Drosophila recessive sex-linked lethal positive. Teratogenic cytogenetic damage in vitro, Chinese hamster cells positive for chromosomal aberrations, in vivo cytogenetic damage, rodent bone marrow cells positive for chromosomal aberrations. Carcinogenicity Classified as a carcinogen with sufficient evidence in laboratory animals. Minimum toxic concentration for inhalation in mice/(weeks, consecutive) positive carcinogenicity. Minimum toxic dose for mice oral administration/(weeks, consecutive) positive carcinogenicity. Hazardous Characteristics: It is flammable when exposed to open flames and high heat.

Emergency Treatment Methods
1. Emergency Response to Leakage
Evacuate personnel in the leaked contaminated area to a safe area, and prohibit unrelated personnel from entering the contaminated area. It is recommended that emergency responders wear positive pressure self-contained breathing apparatus and chemical protective clothing. Wear gas masks. Wear general fire protection clothing. Do not directly Contact the leakage. Plug the leak when ensuring safety. Spray water to reduce evaporation. Mix with sand, dry lime or soda ash, then collect and transport to waste disposal site for disposal. You can also rinse with large amounts of water, diluted detergent Put the water into the wastewater system. If there is a large amount of leakage, use the dike to contain it, and then collect, transfer, recycle or discard it after harmless treatment.
2. Protective measures
Wear respiratory protection when you may be exposed to its vapor. Gas mask. When rescuing or escaping in an emergency, it is recommended to wear self-contained breathing apparatus. Wear chemical safety glasses for eye protection. Wear corresponding protective clothing. Wear chemical-resistant gloves for hand protection. Smoking, eating and drinking are strictly prohibited at other work sites. . Wash thoroughly after work. Carry out pre-employment and regular physical examinations.
3. First aid measures: In case of skin contact, take off contaminated clothing and rinse with running water. In case of eye contact, immediately lift the eyelids and rinse with running water. If inhaled, escape quickly. Move the scene to a place with fresh air. Keep the respiratory tract open. Perform artificial respiration if necessary. Seek medical attention. Gastric lavage if ingested. Seek medical treatment for fire-fighting methods: anti-soluble foam, foam, carbon dioxide, dry powder, sand.
