A survey was conducted to determine environmental asbestos (1332214) exposures at Chemical Sealing Corporation (SIC-2891), Kansas City, Missouri, in March 1972. The survey was requested by a manager on behalf of 40 workers. Thirty five breathing zone samples of atmospheric dust were collected on Millipore filters. The Department of Labor emergency standard for asbestos dust exposure was 5 fibers per milliliter no more than 5 microns in length for an 8 hour time weighted exposure. One batch mixer was exposed to an asbestos concentration higher than the standard; he wore an approved respirator when loading the mixers. A vacuum cleaner was not available for dust removal. Employees provided and maintained their own work clothes. The lunch room was too close to the work area, and served as an entry to the locker areas. The authors recommend confinement of asbestos mixing using a slurry instead of dry asbestos. Floors and equipment should be vacuumed and vacuums should be available for removing dust from clothing. Coveralls should be provided and maintained by management. A separate entrance should be provided for wash rooms and locker rooms, and the lunch room should be located away from the dust producing areas.
