Abstract
A survey was conducted to determine the effects of hot environments on the physical well being of workers in the Ethyl Corporation (SIC- 1476) in Baton Rouge, Louisiana on July 24 to 28, 1961. The survey was requested by Local 12900 of the United Mine Workers on behalf of an unspecified number of employees. The facility was examined for temperature, ventilation and effects of outside conditions. Sweat loss, pulse rate, and mouth temperature of 21 workers were measured throughout each shift. Air temperature readings ranged from 92.0 to 140.0 degrees Fahrenheit (F), due to equipment surface temperatures of 100 to 450 degrees F. Outside conditions had little effect on the inside temperature; there was often a 15 degree F difference in temperatures. Air velocity ranged from 50 to 2500 feet per minute. Mouth temperature of the workers increased an average of 0.38 to per minute, and the sweat loss rate averaged 651 to 900 grams per hour during the three work shifts. Workers were allowed frequent rest breaks in an air conditioned lunch room where their heat build up was dissipated. The authors conclude that physiological strain shown by the workers is not very great and that the main variable in the environment of the shops is ventilation. They recommend installation of an easily read temperature measurement device on risers and a more efficient method of air cooling, shielding air supply intakes more completely, checking and changing faulty air directional structures, obtaining more air movement at rear of the cells, and lowering of temperature of the air drawn into the cell rooms.
