Personal heat stress monitoring.
NIOSH 1980 Dec; :110-128
A prototype seven channel radiotelemetric personal monitoring system was developed for measuring heat stress and recording the physiological responses of individuals in hot job activities. The system consists of a backpack unit and a light, portable receiving station, and is well adapted for use in both open field and industrial settings. Tests have shown that the system is capable of measuring air temperature, humidity, and heat radiation, while also monitoring skin temperature, rectal temperature, and heart rate. The new system was applied successfully to measure the response to thermal stress of fire fighters and steel workers, generating highly useful environmental and physiological data on a continuous basis and made possible the determination of the effect of exposure to high intensity heat stress for short periods of time. The addition of a transceiver provided a voice connection between the test subjects and the observers in instances where there was no contact between the former and the latter. An added dimension was the fact that the newly developed personal heat stress monitoring system allowed for real time observations, without the use of cables and connective wires. The author recommends the development of low cost, miniaturized heat stress monitoring systems for a better understanding of the relationship between heat stress and heat strain in occupational settings.
