San Antonio City Council ordinance (enacted August 31, 2023) requiring contractors and subcontractors performing work on city-funded contracts to provide a 15-minute rest break every 4 hours when the heat index reaches 95°F, provide a heat-relief station (shade and drinking water), and submit a written heat-safety plan for the contract. The ordinance is deliberately scoped to city-funded contract work to avoid preemption under Texas HB 2127 (the 'Death Star' law), which preempts most local occupational-safety regulation. There is no Texas state heat standard; private-sector outdoor workers in Texas who are not on city contracts remain under federal OSHA only.

No standalone formula is published for this standard; see programmable logic and parameters below.
Governing metric: Heat index (city-contractor rest-break trigger)
Programmable logic: Emits baseline controls (written heat-safety plan; heat-relief station with shade and water) for all city-contractor work. When heatIndexF is at or above 95°F, raises an alert and adds the mandatory 15-minute rest break every 4 hours. Does not produce a numeric work/rest schedule; stopWork is always false. Applies only when usStateCode is TX. Regulatory scope distinguishes mandatory (city contractors) from advisory-only (other private-sector TX outdoor workers covered by federal OSHA only).
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.
