HEAT GUIDELINES

EXCESSIVE HEAT IMPACT ON PLAY

Depending on your Region Category, it is recommended that
training or match play be canceled or delayed until cooler when
WBGT exceeds these levels:

• Region Category 1 >86.2°F;
• Region Category 2 >89.9°F
• Region Category 3 >92.0°F

Once an alert level is determined, follow these “Work to Rest”
ratios to modify training to help ensure safe play:

• Alert Level Black – No outdoor training, delay training until
cooler or cancel.

• Alert Level Red – Maximum of one hour of training with four
separate 4 minute breaks within the hour. No additional
conditioning allowed.

• Alert Level Orange – Maximum two hours of training time
with four separate 4 minute breaks each hour, or a 10 minute
break after 30 minutes of continuous training

• Alert Level Yellow – Use discretion, provide three separate
4 minute breaks each hour, or a 12 minute break every 40
minutes of continuous training

• Alert Level Green – Normal Activities, provide three separate
3 minute breaks each hour of training, or a 10 minute break
every 40 minutes.
