How to treat 3,4-Dichlorobenzotrifluoride leakage

Hazards of 3,4-Dichlorobenzotrifluoride

Hazard Class:  Class 6.1 （toxic chemicals）.

Pathways: inhaled, ingested, percutaneous absorption.

Health hazard: inhalation, ingestion or absorption through the skin after hazardous to health. It may stimulate eyes, skin, mucous membranes and upper Respiratory.

Environmental hazards: a hazard to the environment may cause pollution of water bodies.

Explosion Hazard: 3,4-Dichlorobenzotrifluoride(CAS NO: 328-84-7) is flammable.

FIRST AID MEASURES

Skin contact: Remove contaminated clothing, use soap and water thoroughly washed skin.

Eye contact: Did eyelid, mobile or saline irrigation water. See Doctor.

Inhalation: rapidly from the scene to fresh air. Keep the airway patency. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. See Doctor.

Ingestion: drink plenty of water, induce vomiting. See Doctor.

Fire measures

Hazardous characteristics: in case of fire, high-heat combustion caused the explosion. 3,4-Dichlorobenzotrifluoride may react with oxidants. Its vapor is heavier than air, gas heavy, spread to the lower Department of considerable local and met the fire will fire back. If 3,4-Dichlorobenzotrifluoride contacts with high fever, increased pressure within containers, may happen to cracking or explosion.

Hazardous combustion products: carbon monoxide, carbon dioxide, hydrogen chloride, hydrogen fluoride.

Fire fighting methods: as far as possible to move containers from the scene empty Department.

Extinguishing Media: Dry or dry sand.

Fire precautions and measures: firefighters are required to wear gas masks, body wear firefighting suits, and stand the wind direction to fire.

ACCIDENTAL RELEASE MEASURES

Withdrawal air leakage personnel to a safe area rapidly, and isolate and strict restrictions on access.

Cut off the fire source. We recommended that the emergency personnel should wear self-Pressurized respirators and protective clothing. Possible cut off the source of leakage. Preventing access to sewers, flood discharge trench so restrictive space. A small leak: activated carbon or other inert materials to absorb. You can also use non-flammable dispersant made of latex, wash, lotion diluted Add to the wastewater system. Large leak: to build a causeway or trenching asylum. Covered 3,4-Dichlorobenzotrifluoride with foam to suppress evaporation. Ex pump used to transfer tankers or exclusive collector, recycling or shipped to the waste disposal sites.
