Spray Application of Fireproof Insulation at the Construction Site of the Proctor and Gamble Technical Center, Blue Ash, Ohio.

PB90155920

Publication Date	1972
Personal Author	Lemen, R. A.
Page Count	8
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. During the spraying operation, each of the four workers became literally covered with the sprayed-on material. Buildings, grounds, and everything within a 50-foot radium of the spray unit were also covered. 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 cleaned up around the area of spraying by dry sweeping. Respirators should 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 substituted.
