Heat Illness Prevention
What is the heat index?
When summer heat intensifies, all eyes are focused on the temperature. But often, it is the heat index that should draw more concern. It is a better indicator of the intensity of the heat and the dangers it can present to people. The heat index is a combination of temperature and humidity. It measures how hot it feels outside when humidity and other factors are considered along with the temperature.
When the heat index reaches 105 degrees or above, Principals should prepare for indoor physical activity in an air-conditioned environment and follow the Heat Index Guidelines below. These guidelines are not to be considered exhaustive. Reason and good judgment must be used at each site to protect students and staff.
