No standalone formula is published for this standard; see programmable logic and parameters below.
Governing metric: Heat Index (°C)
Programmable logic: Uses 4 heat-index levels (yellow/orange/red/purple) to apply escalating outdoor work controls from basic shade/water through mandatory hourly rest to outdoor work suspension. Specific heat-index thresholds from Table 3 PDF are approximate pending direct extraction.
This standard does not take WBGT as a required input, and publishes no standalone numeric parameter table here; see the governing metric and programmable logic above, and the primary source below.
Required inputs: none
Optional inputs: heatIndexC, heatIndexF, airTempC, relativeHumidity
