Radiotelemetry-based study of occupational heat stress in a steel factory.

Abstract

Heat stress conditions prevailing in a steel factory were evaluated using a newly developed radiotelemetry system. This system was used as a station monitor for determining environmental temperature conditions and as a personal monitor to obtain data of worker physiological responses. Environmental information was used in calculating wet-bulb globe temperature heat stress index values. Physiological data were used in confirming safety limits. The study demonstrated the effectiveness of radiotelemetry in assessing occupational exposures to heat stress.
