CAS Number: 593-60-2. A colorless gas that is used primarily in
the manufacture of flame retardant synthetic fibers. Chemical
formula = C2H3Br. Molecular weight = 106.9 g/mol.
Workers may be occupationally exposed to vinyl bromide via
inhalation during its manufacture or use. Acute (short-term) and
chronic (long-term) studies indicate that the liver is the
primary target organ following inhalation exposure to vinyl
bromide in humans and animals. In high concentrations, vinyl
bromide may produce dizziness, disorientation, and sleepiness in
humans. Acute exposure of rats to very high concentrations via
inhalation has showed liver and kidney damage and neurological
effects. Chronic inhalation exposure primarily damages the
liver, causing foci in the liver of rats. Vinyl bromide has been
shown to be a potent carcinogen in rats exposed by inhalation,
producing liver angiosarcomas. EPA has classified vinyl bromide
as a Group B2, probable human carcinogen.
