No standalone formula is published for this standard; see programmable logic and parameters below.
Governing metric: Outdoor dry-bulb air temperature (°F)
Programmable logic: Shade must be present when temperature exceeds 80°F (provided on request at or below 80°F). High-heat procedures trigger at ≥95°F for agriculture, construction, landscaping, oil/gas extraction, and transportation/delivery. Always require water, cool-down rest, emergency response, training, and a written plan. No fixed work/rest ratio.
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: airTempC, usStateCode, industry, acclimatization, workload
