Abstract
Environmental surveys conducted on February 4 and July 16, 1985 at the Denver Water Department (SIC-4941), Denver, Colorado, included collection of breathing zone and general area samples for asbestos (1332214) and personal sampling for noise exposure. The Denver Water Department had requested an evaluation of potential health hazards to employees during cutting of cement pipes thought to contain asbestos. Without a water suppression system in use, personal samples for asbestos ranged from 2.27 to 3.54 fibers per cubic centimeter (f/cc); with suppression system in use, samples ranged from 0.43 to 0.76f/cc. Without a suppression system, area samples within 10 to 15 feet of the cutting operation ranged from 1.90 to 2.18f/cc; with suppression, results ranged from 0.17 to and the OSHA Standard is 2.0f/cc. All samples exceeded the NIOSH criteria. Personal noise level measurements ranged from 95 to 109 decibels A (dBA); half of the samples exceeded the NIOSH short term exposure criteria of 100dBA for 1 hour exposure periods. The author concluded that a health hazard from asbestos exposures exists to workers involved in the cutting operation; workers in the immediate cutting area and downwind are also at risk. A health hazard from exposures to noise was considered to exist for the employee who performs pipe cutting. Recommendations are made to reduce or eliminate the exposures.
