072 Tetrachloroethylene Cl2C=CCl2
Synonyms: Perchloroethylene.
Ethylene tetrachloride, Nema, Carbon dichloride,
Tetracap, Perclene.
Life Hazard: Incoordination and impaired judgement may occur at vapor exposures from
300 ppm to 1000 ppm. Dizziness, drowsiness, loss of consciousness and
even death can occur at increasing levels of exposure. When involved in
fire, tetrachloroethylene emits highly toxic and irritating fumes of chlorides,
a suspected carcinogen.
Flammability: The compound has no flash point. Vapor may decompose at high
temperature such as open flame, red-heated materials, with evolution of
poisonous gases such as chlorine, carbon monoxide, phosgene.
Handling: Store in a closed container in a cool place. Protect against direct sunlight.
Do not store in ill-ventilated cellars and hollow places owing to high vapor
density. Wear safety goggles, gas mask, rubber gloves. Adequate
ventilation.
Emergency Treatment and Measures:
a. Hygienic Precautions: Examine liver and kidneys periodically. Preclude from
exposure those individuals with diseases of heart, liver, kidneys and lungs.
b. First Aid: Irrigate eyes with water. Wash contaminated areas of body with soap
and water.
If swallowed, call a physician.
Administer oxygen for
oxygen-shortage.
Spills:
Absorb on paper and evaporate on a glass dish in hood. Burn the paper. The
compound should be redistilled and reused.
073 Tetra Ethyl Lead Pb(C2H5)4
Synonyms: Lead tetraethyl, TEL.
Life Hazards: Powerful poison and a solvent for fatty materials. Suspected carcinogen.
Flammability: Flash point (85C), Decomposes above 110C. Violently explodes when
heated to more than l70C.
Handling: Decomposes when exposed to sunlight or allowed to evaporate. Separate
from halogenated compounds or oxidzing agents.
Emergency Treatments and Measures:
