WET BULB GLOBE TEMPERATURE (WBGT) FROM TEMPERATURE & RELATIVE HUMIDITY

Temperature F

Proposed Guidelines after 7 days nor activity acclimization period

"Very Low Risk" okay for all levels of activity

WBGT is between 82 - 87, Very Warm, "Low Risk" okay for all levels of activity, water consumption and breaks increased.

WBGT is between 82 - 87, Watch "at risk" athletes carefully

WBGT is between 88 - 90, Hot, "Moderate Risk" okay for only acclimatized athletes, increase water consumption & breaks, no full pads.

WBGT is between 88 - 90, Maximum of 2 hour practice. Limit Football pads to helmet, Shoulder pads, and shorts. Remove equipment for conditioning.

WBGT is between 91 - 92, Very Hot, "High Risk" okay for only acclimatized athletes, limit practice sessions to one 1.25 hours, helmets only for football.

WBGT is between 91 - 92, No outdoor conditioning exercises. Must have 5 minute shaded break every 15 minutes.

WBGT is between 92- 93.9, Dangerously Hot, "Very High Risk" temperature. Move practices to cooler time. Only acclimized athletes may participate outdoors.

WBGT is between 92- 93.9, Limit outdoor exposure to 1 hour. Five minute water break after 10 minutes of activity. No conditioning, no running drills.

WBGT is between 92- 93.9, AT must be present at practice. Modified scrimmage/game with mandated breaks (1/2 way through each period/session).

WBGT is above 93.9, VERY Dangerously Hot, "Very High Risk" temperature. Move practices to cooler time. No outdoor activities should be taking place.

These "Zones" are progressive. The CAUTIONS at the lower levels are continued as conditions worsen
