No standalone formula is published for this standard; see programmable logic and parameters below.
Governing metric: GeoSphere Austria heat warning level (1–4); mandatory measures at level 2+
Programmable logic: The Hitzeschutzverordnung creates a graduated control overlay for outdoor workers in construction, delivery, security, waste management, festival operations, landscaping, and similar sectors. The duty to implement protective measures — a heat protection plan including UV protection, shade, adjusted work hours, cooling, hydration, worker information, and special consideration of vulnerable workers — engages when GeoSphere Austria issues a heat warning of at least level 2 (orange/Vorsicht) in the worksite area. At level 3 (red/Gefahr) and level 4 (extreme/Große Gefahr) 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
