First-aid measures

Health Hazards:
The substance is irritating to the eyes and the skin. Inhalation exposure could cause lowering of consciousness, dizziness, drowsiness, headache, weakness, nausea.

Skin and Eyes:
If trichloroethylene is splashed on the skin, contaminated clothing shall be promptly removed and the skin washed with soap and water.
If liquid trichloroethylene contacts the eyes, they shall be thoroughly irrigated with plenty of water for several minutes. Medical assisstance shall be promptly provided in cases of eye splashes.
If a person breathes in large amounts of trichloroethylene, move the exposed person to fresh air at once. Keep the affected person warm and at rest. Get medical attention.

Fire-fighting measures

Under ordinary conditions of use, trichloroethylene is non-flammable and non-explosive
Fire Hazards:
Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
In case of fire: keep drums, etc., cool by spraying with water.

Accidental release measures

Do NOT let this chemical enter the environment.
Collect leaking and spilled liquid in sealable containers as far as possible.
Absorb remaining liquid in sand or inert absorbent and remove to safe place.

Exposure controls / personal protection

Engineering controls and work practices:
Should be sufficient to reduce exposures below the workplace standards for trichloroethylene established by the national regulations to the lowest level achievable.
Personal Protective Equipment:
Respiratory Protection:
Respiratory protection should be used in accordance with company and applicable national regulatory requirements.
Respiratory protection should be used to supplement the engineering controls and work practices.
Persons should not be assigned to tasks requiring the use of respirators unless it has been determined they are physically able to perform the work and are trained to use the equipment.
Protective clothing:
For operations where the worker may come into direct contact with liquid trichloroethylene, protective clothing (chemical impervious and resistant) shall be worn. Gloves, boots, overshoes, and aprones shall be provided when necessary.
All protective clothing shall be well aired and inspected for physical defects before reuse.

Eye protection:
In work operations where trichloroethylene (liquid or spray) may come in contact with the eye, eye protection shall be provided. Chemical type goggles, safety glasses with splash shields shall be used.
Suitable protective clothing and eye protection should be in accordance with national, or regional standards and regulations.

Stability and reactivity

On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive fumes.
The substance decomposes on contact with strong alkali producing dichloroacetylene, which increases fire hazard.
Reacts violently with metal powders such as magnesium, aluminium, titanium, and barium.
Slowly decomposed by light in presence of moisture, with formation of corrosive hydrochloric acid.

Disposal considerations

This substance, when discarded or disposed of, is a hazardous waste. The transportation, storage, treatment, and disposal of this waste material must be conducted in compliance with local regulations for hazardous wastes.
