William T. Marr, "Asbestos Exposure During Naval Vessel Overhaul" (1964)

A five-page article by William T. Marr of the Medical Department, Long Beach Naval Shipyard, in the May–June 1964 American Industrial Hygiene Association Journal. Marr reported that five of the shipyard's 60 to 80 insulation workers had retired on disability for asbestosis and that one pipe coverer had died of it in 1962. He measured dust while shipboard insulation was installed and removed, found removal during overhaul "extremely dusty," and warned that x-rays were not enough for control because asbestosis usually takes at least seven years to show.

What it shows

The article describes how shipyard pipe coverers worked with amosite blankets, magnesia and calcium silicate blocks and asbestos cloth, and concludes that shipboard pipe covering "is a hazardous trade" whose workers should wear respirators around dry asbestos insulation. Among its sources is personal correspondence with H. M. Jackson of Johns-Manville (Motley document 148).
