There are also minimum break time requirements for each temperature tier, and limitations on wearing full pads in practice when the heat index reaches 95 degrees. Each school is responsible for obtaining a wet-bulb globe thermometer as their first choice in evaluating conditions. In the absence of a Wet Bulb Globe Temperature reading, a digital psychrometer or other instrument may be used at the site of the activity to measure the heat index. The use of a weather app on a cell phone is permissible to measure heat index if no other instrument is available to measure heat index at the site of the practice or competition.
