The main uses for 2-chloroacetophenone are in tear gas and in
chemical Mace. It is a potent eye, throat, and skin irritant.
Acute (short-term) inhalation exposure of humans causes burning
of the eyes with lacrimation, some degree of blurred vision,
possible corneal damage, irritation and burning of the nose,
throat, and skin, and burning in the chest with dyspnea. Acute
dermal exposure is irritating and can result in first, second,
and third degree chemical burns in humans. Squamous hyperplasia
of the nasal respiratory epithelium was reported in rats
chronically exposed (long-term) via inhalation. EPA has not
classified 2-chloroacetophenone with respect to potential
carcinogenicity.
