Hazards such as chemical, fire, and ergonomic-related are associated with dry cleaning processes. Exposure to hazardous chemicals commonly used in dry cleaning shops may occur through skin absorption, eye contact, or inhalation of the vapors. Perchloroethylene (PERC), a potential human carcinogen, is the most commonly used dry cleaning solvent. Symptoms associated with exposure include: depression of the central nervous system; damage to the liver and kidneys; impaired memory; confusion; dizziness; headache; drowsiness; and eye, nose, and throat irritation. Repeated dermal exposure may result in dermatitis.
