Heat Stress Risk Index (HSRI)
The cricket specific HSRI tool has been developed specifically by CA to be used in determining the heat stress risk to Participants in Community Cricket. The HSRI tool is available below.
The following key values are needed to calculate the HSRI:
- air temperature in the shade (oC);
- wind speed (in km/h);
- relative humidity (%);
- sun exposure (clear sky, partly cloudy, overcast or night)
Air temperature, wind speed and relative humidity can be obtained from credible online weather data sources. CA recommend locating the weather station closest to the ground via the Bureau of Meteorology (BOM) and using those data.
Sun exposure (also known as sun radiation) is determined by the person entering the data into the HSRI by observing for one of the four available options (clear sky, partly cloudy, overcast & night).
