How To Use Heat Index:

1. Across top locate Temperature

2. Down left side locate Relative Humidity

3. Follow across and down to find Apparent Temperature *

4. Determine Heat Stress Risk on chart below

Apparent Temperature

Heat Stress Risk with Physical Activity and/or Prolonged Exposure

90° to 105°

Heat cramps or heat exhaustion possible

105° to 130°

Heat cramps or heat exhaustion likely, Heatstroke possible

130° and up

Heatstroke highly likely
