Technical assistance report no. TA-77-20, St. Elizabeth's Hospital, Washington, D.C.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, TA 77-20, 1977 Jul; :1-7
Environmental air samples were analyzed for asbestos (1332214) at Saint Elizabeths Hospital (SIC-8063) in Washington, D.C. on February 16 and 17, 1977. An evaluation request came from an authorized representative of the hospital on behalf of an unspecified number of construction workers under contract at St. Elizabeths Hospital as well as the general hospital staff. Asbestos concentrations with fibers greater than 5 microns in length ranged from 0.11 to 3.02 fibers per cubic meter (f/cc), compared with the NIOSH recommended 8 hour time weighted average standard of 0.1f/cc greater than 5.0 microns in length. The author concludes that the construction workers and certain hospital employees are exposed to excessive concentrations of asbestos containing dusts during construction. He recommends use of Local exhaust ventilation at the construction site, use of hazard warning signs, limited access to the construction site, use of full face respirators, and personal and housekeeping hygienic measures.
