Yukon Occupational Health Regulations (O.I.C. 1986/164) s.12 'Heat stress': the employer determines the thermal index (WBGT or wet globe temperature) and workers shall not work continuously when the 2-hour average exceeds the limit for the workload and air velocity.

The drag-to-check calculator needs JavaScript. Every value it can show is a row of the table below, which is computed by the same engine.
No standalone formula is published for this standard; see programmable logic and parameters below.
| Parameter | Value |
|---|---|

lightWbgtLowHighC | 30–32 |
moderateWbgtLowHighC | 28–31 |
heavyWbgtLowHighC | 26–29 |
Programmable logic
WBGT limits (low air velocity below 91 m/min / high above): light 30/32, moderate 28/31, heavy 26/29 C. WBGT above the limit: no continuous work; engineering controls or work-rest cycles. Screening limit: no work/rest schedule is published. Without an air-velocity input the low-velocity column is used. Very heavy work uses the heavy row. Wet globe temperature (WGT) column not modelled.
Required inputs: wbgtC, workload
Optional inputs: windSpeedMS
