Abstract
Worker exposures to asbestos (1332214) during application of fireproofing insulation materials at the Proctor and Gamble site in Blue Ash, Ohio were examined. Personal membrane filter sampling devices were placed on four workers involved in the spraying and mixing operation. The samplers were run for about 30 minutes at a flow rate of 1.7 liters/minute. During the spraying operation, each of the four workers became literally covered with the sprayed on material. Not only were the workers covered, but also the buildings, ground, and everything within a 50 foot radium of the spray unit. Only the mixer pump operator was furnished with a respirator which he was not wearing when observed. The workers took their work clothing home at the end of the day. Even though the exposure to the workers was below the standard at the time of wet spraying, increased exposures were possible to the mixer pump operator when opening the bags with the asbestos containing material, and also after the sprayed on material had dried and was being cleanup up around the area of spraying by dry sweeping. The author recommends that respirators be supplied to all workers spraying or cleaning up or working around the asbestos containing material. Clothing and laundering should be provided by the company doing the spraying. The use of hanging tarpaulins was suggested to prevent the spread of the materials outside the spraying area. Materials not containing asbestos should be used in place of those which do contain asbestos.
