Annual Report of the Surgeon General, U.S. Navy, Chief of the Bureau of Medicine and Surgery, to the Secretary of the Navy Concerning Statistics of Diseases and Injuries in the United States Navy for the Calendar Year 1939

Excerpt from the US Navy Surgeon General's annual report for calendar year 1939: the title page and about four pages (roughly pp. 22-25) of the section on hygienic and sanitary conditions afloat and ashore, in a copy certified by the National Archives in 1985. The pages cover industrial hygiene at navy yards. At one yard, the 11 men of the pipe covering and insulating shop, exposed for 1.7 to 17 years to amosite dust from cutting insulating felt, were surveyed for asbestosis; their X-rays were essentially negative, but an exhaust blower over the work table was recommended. Norfolk Navy Yard reported attention to asbestos pipe-covering, amosite and fiberglass insulation and had no dust-counting instruments.
