Use

Inhalation of methyl chloride can produceheadache, dizziness, drowsiness, nausea,vomiting, convulsions, coma, and respiratoryfailure. It is narcotic at high concentrations.Repeated exposures can produce liver and Methyl chloride caused adverse reproduc tive effects in test animals. These includeembryo toxicity, fetal death, developmentalabnormalities, and paternal effects in rats andmice. It tested positive to the histidine rever sion–Ames test for mutagenicity. The car cinogenic properties of this compound havenot been established. The evidence in ani mals and humans is inadequate.
