This rule has no numeric trigger the calculator evaluates — it states duties and control measures rather than a threshold a reading can be checked against. Its measures are listed below.
No standalone formula is published for this standard; see programmable logic and parameters below.
Programmable logic
Triggered at heat index ≥80°F. Three tiers: 80–89°F baseline monitoring (60/0); 90–99°F mandatory 10-min cool-down break per 2-hour period (50/10); ≥100°F mandatory 15-min break per period (45/15). 1 qt/hr cool water required.
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, outdoor, acclimatization
