alpha-T - Introduction
Open Data Unverified Data
1,1, 1-trichloroethane is a flammable, toxic, and irritating gas. In case of open flame, high energy combustion, and produce highly toxic phosgene and hydrogen chloride smoke. Strong reactions with alkali metals and alkaline earth metals can occur. It can react with active metal powders (e. G., magnesium, aluminum, etc.) to cause decomposition.

- fire extinguishing agent: water mist, foam, carbon dioxide, sand.
emergency treatment of leakage
- emergency treatment: prompt evacuation of personnel from the leak-contaminated area to the safety zone, and proceed to Isolation, with strict restrictions on access. Cut off the fire source. Emergency personnel are advised to wear self-contained positive pressure respirator and anti-virus clothing. Access to the scene from upwind. Cut off the source of leakage as far as possible. To prevent the flow of sewage, flood drains and other restrictive space.
- small leakage: adsorption or absorption by sand or other incombustible materials.
- large amount of leakage: Construction of embankment or excavation for accommodation. Cover with foam to reduce vapor hazards. The explosion-proof pump is transferred to the tank car or a special collector for recycling or transportation to the waste treatment site for disposal.
handling and storage

It is recommended that the operator wear a direct type gas mask (half mask), safety full protection glasses, anti-virus infiltration work clothes and chemical protective gloves. Stay away from fire and heat source. No smoking is allowed in the workplace. The use of explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidants and alkalis. Handling should be light and light unloading, to prevent packaging and container damage. Fire fighting equipment and emergency treatment equipment for leakage shall be provided with corresponding varieties and quantities. Harmful substances may remain in the empty container.
- precautions for storage: Store in a cool and ventilated warehouse. Keep away from fire and heat source. Keep the container sealed. It should be stored separately from oxidant, alkali and edible chemicals, and mixed storage should not be avoided. With the corresponding varieties and quantity of fire fighting equipment. The storage area shall be equipped with emergency treatment equipment for leakage and appropriate containment materials.
