• Description:
  A heat stress survey was conducted at a surface coal mine in Man, West Virginia, on July 20 and 21, 1978. The evaluation was requested on behalf of cab operators of heavy equipment. Heat stress was measured using wet bulb globe temperatures (WBGT) and dry bulb temperatures. Vehicles surveyed included a 50 ton Kenworth coal truck, a 40 ton Cline coal truck, a D9 Earthmover, and a 50 ton Caterpillar rock truck. The threshold limit value for continuous work of the type surveyed was 88 degrees-F for acclimated workers. On July 20, peak air temperatures of about 88 degrees-F were reached between the hours of 3 and 4 in the afternoon. WBGT in the cab of the D9 Earthmover exceeded the outdoor temperature by about 2 degrees-F. On July 21, the outdoor temperature was about 91 degrees- F during the same time period, with WBGT at about 90 degrees-F in the D9 Earthmover and in the Caterpillar rock truck cabs. The author recommends a work/rest cycle of 60 minutes per hour at 88 degrees-F WBGT, 45 minutes per hour at 89 or 90 degrees-F WBGT, and 30 minutes per hour at 91 degrees-F WBGT. A monitoring program should be initiated to determine the WBGT during hot weather. [Description provided by NIOSH]
