Abstract
A follow up heat stress survey was conducted in the steam tunnels of the steam distribution system for the Federal buildings in Washington, DC to evaluate the existing environmental heat load and environmental controls within the tunnel network during the warm summer months and physiological strain incurred by the tunnel workers. During July 1972, 241 heat measurements were taken at various locations throughout the tunnel system. Primary importance was given to gathering data at the same measurement sites within the tunnel system which had been surveyed in the February phase of the study. Jobs were categorized according to the nature of the exposure into the following groups: walk through inspection, tunnel repair work, inspection and repair work in manholes and buildings, fan repair, and cleaning the tunnels. The authors recommend that work be rescheduled on the walk through inspections into shorter work bouts, providing more rest periods. The hot work should be distributed evenly throughout the week rather than concentrated in 1 or 2 consecutive days. Tunnel repair personnel should be provided with self contained cooling suits for usage during prolonged repair duties in the summer months. A course of instruction should be provided to educate tunnel workers on the problems of heat stress, symptoms of heat disorders, and remedial actions to take.
