Listing of Shock Sensitive Chemicals
Meanings of Physiological Classifications
Irritants: These are materials that cause inflammation of mucous membranes. Examples
of irritants are: ammonia, alkaline dusts and mists, hydrogen chloride, hydrogen floride,
halogens, ozone, phosgene, diethyl/dimethyl sulfate, nitrogen dioxide, phosphorous
chlorides, and arsenic trichloride. They can also cause changes in the mechanics of
respiration and harm lung function. Chemicals that cause this type of irritation include:
Acetic acid, acolein, formaldehyde, formic acid, iodine, sulfur dioxide, and sulfuric acid.
Asphyxiants: These are inert gases that displace oxygen, or reduce the body’s ability to
absorb, transport, or utilize inhaled oxygen. Examples include: Nitrogen, nitrous oxide,
cardon dioxide, hydrogen, helium, carbon monoxide, and cyanides.
Anesthetics: Chemicals that have a depressant effect on the central nervous system.
Examples include: Halogenated hydrocarbons and alcohols.
Hepatotoxic agents: Chemicals that may damage the liver. Examples include: Carbon
tetrachloride, tetrachloroethane, and nitrosamines.
Nephrotic agents: Chemicals that may damage the kidneys. Examples include:
Halogenated hydrocarbons and uranium compounds.
Neurotoxic agents: Chemicals that damage the nervous system. Examples include:
Trialkyl tin compounds, tetraethyl lead, methyl orange, methyl mercury, carbon disulfide,
organic phosphorus insecticides, thallium, and manganese.
Blood and Hematopoietic agents: These agents damage the blood and/or bone marrow.
Examples include: Nitrates, aniline, toluidine, nitrobenzene, and benzene.
Pulmonary agents: These agents cause fibrotic changes and damage pulmonary tissue.
Examples include: Coal dust, cotton dust, wood dust.
Carcinogenic agent: These agents cause the proliferation of malignant neoplastic cells.
Known carcinogens include: Asbestos, alpha-nathylamine, dicholorobenzidine, vinyl
chloride, ethylene oxide, methyl chloromethyl ether, inorganic arsenic, and coal tar
derivative volatiles.
Teratogen agent: These are chemicals that interfere with normal embryonic
development without killing the fetus or damaging the mother. Examples include: lead
and thalidomide.
Sensitizer agents: These are chemicals that cause allergic reactions in normal tissue after
repeated exposure to that chemical. Examples include: Epoxies, nickel compounds,
poison ivy, toluene diisocyanate, chromium compounds, and chlorinated hydrocarbons.
