Temperature

Activity Level

Green I 82-84.9 Discretion is required when planning heavy exercise for acclimatized personnel.

Yellow II 85-87.9 Strenuous exercise and activity for new and un-acclimatized personnel during the first 30 days of heat exposure.

Red III 88-89.9 Strenuous exercise should be curtailed for personnel with less than 12 weeks of training in hot weather.

Black IV Above 90 Physical training and exercise should be curtailed for all personnel (operational commitments excluded).

Heat stroke likelihood is high under conditions of high exertion.

Calculations: WBGT = WB X 0.7 + DB X 0.1 + GT X 0.2

Meter calibration should be manually verified every 3 months. Manual calculation must be 0.2 + the meter WBGT readout

must be summoned.
