I. H. Weaver to J. H. Marsh on Testing Asbestos Cloth for Release of Airborne Fibers (1973)

A one-page Raybestos-Manhattan memo of March 7, 1973, from I. H. Weaver of the Manheim division to J. H. Marsh in Bridgeport, headed "Testing Asbestos Cloth for Release of Airborne Fibres." Weaver discussed tests of the dust released when asbestos cloth is handled or used to wrap pipe insulation. He reported that an Asbestos Textile Institute committee had recommended McGill University to test fiber release from asbestos safety clothing, and that it was agreed a third party "should certify the tests rather than ATI or any of the manufacturers involved."

What it shows

Weaver had first suggested using the same outfit that tested asbestos coats for the Food and Drug Administration. He then wrote that the test had been done by the National Institute for Occupational Safety and Health (NIOSH), "and I doubt that we would want to get them involved in investigation of our pipe covering materials." The memo shows how the company weighed who would test its products for fiber release. The McGill study it led to is discussed in John Marsh's 1974 memo.

In Johns-Manville's index

Johns-Manville's legal department indexed the Motley 1,000 in 1984. Its index describes this document as follows:

I.H. Weaver memo to J.H. Marsh, 3/7/73, entitled "Testing Asbestos Cloth for Release of Airborne Fibers." Weaver mentions various organizations which are testing asbestos cloth for the release of airborne fibers. Weaver states that at a recent ATI meeting it was recommended that McGill University conduct tests to determine the amount of fibre released during normal use of asbestos safety clothing.
