Heat Stress / WBGT

Screen measured WBGT; does not invent WBGT estimates.

Use a decimal point or comma; no thousands separators.

Calculation inputs

Measured WBGT (°C)Clothing adjustmentWorkload (verify with competent person)Heat acclimatisation

Result

WBGT measurement required. No result without a valid measurement.

Review the methodology and limits below before interpreting this result.

Example: measured 28 + clothing 3 = 31 °C adjusted WBGT; not permission to work. No measurement → no result.

Methodology & limits

Adjusted WBGT = measured WBGT + clothing adjustment

Measure WBGT at the work location using a WBGT meter; air temperature/humidity are not substitutes. Confirm workload and acclimatization; independently assess exposure duration, local rules and individual risk factors.

Calculated at full precision; display rounded to two decimal places only.
