Cleangard (H. K. Porter)

Cleangard was a treatment applied to asbestos textiles by Southern Asbestos Company of Charlotte, North Carolina.1 In a 1975 item in Asbestos, the industry's trade journal, Southern said a special blend was impregnated into each product of its Gardian line of textiles, tapes, yarn, tubing and rope "via Southern's Cleangard process," making them clean, flexible and easy to handle.1 Southern said the Gardian asbestos textiles helped the user comply with OSHA regulations and "require no health hazard label."1 A 1978 item in the magazine said the process was developed to help meet the requirements of the Occupational Safety and Health Act.2

By 1979, H. K. Porter's annual report described Southern Textile Corporation, the new name of Southern Asbestos Company, as a wholly-owned subsidiary of Porter, and listed Cleangard as part of its many-colored Gardian line.3 In 1980 the magazine reported that Southern used Cleangard processing in all its products to lock in the fibers and create superior abrasion resistance, and now offered the treatment on both its asbestos and non-asbestos textiles.4

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Cleangard under H. K. Porter as cloth, tape, yarn, felt and other textiles, made from 1972 to 1974, with an asbestos content of 65-95%.5
