This historical 1952 drawing was provided by the Center for Disease Control's (CDC), National Institute for Occupational Safety and Health (NIOSH), detailing the design of a Detrex Degreaser™, Model IDCR-700, which was used to remove grease from coil steel, introduced during the manufacture process. The grease, used as a rust prevention measure, must be removed before parts are painted and assembled. The machine consists of a large, square vat with electrical coils on the bottom. The tank was filled with liquid trichloroethane, a halogenated hydrocarbon (HHC), which was heated, creating a vapor that removed grease from suspended steel parts. HHCs are a cardiovascular, or blood toxicant. In the 1940s and 1950s, the Industrial Hygiene Division (IHD) investigated hazards associated with many types of manufacturing activities. This design was an example of a measure meant to improve workplace safety by keeping vapors from escaping.
