D. T. Watters to I. P. Blackwood et al. on Potential Health Risks of Insulation Materials (Perlite Insulation Specification 4) (1981)

Memo from D. T. Watters responding to employee irritation complaints at the Institute plant about perlite insulation (Insulation Specification 4) used in ethylene oxide service, and to questions about non-asbestos substitutes. It recommended continued use of Specification 4 with respiratory protection as needed and asked that further complaints be passed to the Central Engineering insulation technologist. Attached is the December 1980 Union Carbide material specification for the perlite insulation, listing acceptable materials and manufacturers.
