摘要

On January 6, 1983, NIOSH received a request to analyze some insulation material that was being removed from a hot water heating system. A walk-through survey the same day showed that most of the material had been removed. Samples were collected and analyzed. Both Amosite and Chrysotile asbestos were present in the insulation. On January 7th, six air samples were collected, all were below the Occupational Safety and Health (OSHA) standard of 2 fibers/cc, one sample was above the NIOSH-recommended standard of 0.1 fiber cc.
