Description:

From 1950, this historical photograph was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), and depicted a Sec cleaning unit in a chlorinated hydrocarbon dry-cleaning plant. In the 1950s, the Industrial Hygiene Division (IHD) investigated hazards in dry cleaning environments. New non-flammable cleaners had recently been introduced that created concerns about their toxicity. Modern dry-cleaning machines now employ a 'closed system', whereupon, clothes may be cleaned, and dried in one machine without having to be transferred between two functionally-different machines.As of 2005, there were approximately 36,000 dry cleaning businesses in the U.S. with most employing less than ten people. The focus today is on the perchloroethylene, used as a solvent in 85% of dry cleaning shops. It is carcinogenic in animals and suspected to be so in humans.
