New York City Executive Order No. 17 (signed June 22, 2026), the city's first worker heat-protection order. A binding executive order with no WBGT or heat-index threshold of its own and no work/rest table; modeled as a control overlay split into mandatory and advisory tiers. Regulation (mandatory): City agencies and contractors must implement heat illness prevention plans when the Heat Emergency Plan is activated; city agencies strictly enforce existing bathroom-access laws during high heat — including Administrative Code §20-563, the enforceable right of food delivery workers to use restaurant bathrooms (restaurants penalized for refusal) — and the Department of Buildings notifies construction operators of heat reporting obligations. Guidance (advisory): water, shade, rest, acclimatization, training, and symptom reporting for the broader outdoor workforce the order names (employees, independent contractors, gig/app-based workers, day laborers, street vendors, delivery, and construction workers).

No standalone formula is published for this standard; see programmable logic and parameters below.
Governing metric: City Heat Emergency Plan activation (heat-index trigger)
Programmable logic: Emits mandatory measures (agency/contractor prevention plans on Heat Emergency activation; strict enforcement of Administrative Code §20-563 food-delivery-worker bathroom access; DOB construction heat-reporting notice) plus advisory best-practice controls (water, shaded/cooled rest, rest breaks, acclimatization, training, symptom reporting). When the City Heat Emergency Plan is active — asserted via heatEmergencyActive, or derived when heatIndexF is at or above 100°F single-day — raises an alert. The two-consecutive-day 95°F activation condition is not derivable from a single reading and must be asserted via heatEmergencyActive. Setting foodDeliveryWorker (or industry 'delivery') surfaces the §20-563 enforceable bathroom right. No fixed work/rest ratio.
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.
