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
The Hitzeschutzverordnung creates a graduated control overlay for outdoor workers.
The duty to implement protective measures — heat protection plan, UV protection, shade, adjusted work hours, cooling, hydration, worker information, special consideration of vulnerable workers — engages when GeoSphere Austria issues a heat warning of at least Stufe 2 (Vorsicht, gelb — gefühlte Temperatur ≥ 30 °C) in the worksite area. At Stufe 3 (Achtung, orange) and Stufe 4 (Gefahr, rot) the same duty applies with increased urgency.
The warning level is zone-specific and forecaster-judged, so it is accepted as an input (geoSphereWarningLevel) rather than derived from temperature; when it is not supplied, the engine surfaces requiresOfficialWarningCheck. Indoor-only work is excluded from scope (outdoorWork=false).
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, indoorTempC, outdoor, geoSphereWarningLevel
