Who reviews all engineering and non-engineering heat-stress surveys to determine obvious inaccuracies, reduced PHEL stay times, any personnel protective actions being taken, and submits heat-stress surveys that result in reduced stay times to the commandi Medical Department Representative (MDR)
Who prepares reports of heat stress related cases? Medical Department Representative (MDR)
Dry-bulb temperature readings: Every ___ hr(s) if do not exceed 85 degrees F; every 1 hr if exceeds 85 degrees F; every ___hr(s) during maintenance/temporary installations exceed 85 degrees F. 4 hours; 1 hour
