Caption:
Worker in a Connecticut hat making plant shrinks and shapes hat felt into the appropriate size for a hat. He does this by dipping the felt in hot water and kneading it on the rotating rollers of the apparatus pictured. Note the steam pervading the atmosphere, lit up by the photographer’s flash. This steam would contain mercury vapor, from carroted fur felt dipped in the kettles of hot water. The plant was part of the 1937-1938 PHS industrial hygiene and engineering study of mercury exposure and its health effects in the hatmaking industry, which was published as USPHS Public Health Bulletin No. 263, Mercurialism and its Control in the Felt-Hat Industry, 1941.
