OSHA quietly extended its Heat National Emphasis Program on April 10, locking in programmed heat-related inspections across construction and 54 other high-risk industries for another five years. The renewal lands as the broader federal heat standard remains stalled in rulemaking, and it gives field offices the enforcement authority they were about to lose.
The NEP doesn’t carry the force of a new substantive standard. It directs OSHA’s regional and state-plan offices to inspect heat-related hazards under the General Duty Clause, with priority on fatality cases and any complaint or referral that involves a heat exposure. For builders, the practical effect is that the agency keeps doing what it’s been doing for the past three years, but with the budget cover to do more of it.
What changed in the renewal
The 2026 version of the program runs through April 2031. It uses 2022-2025 BLS and OSHA data to identify 55 inspection-priority sectors. Manufacturing, wholesalers, restaurants, retail, bakeries, landscaping, and construction sit at the top of the list.
A few procedural changes are worth flagging:
- OSHA removed the prior numerical inspection goal, giving regional administrators more latitude to choose targets.
- The reorganized appendices split program evaluation from citation guidance, which should make Field Operations Manual conformance easier to audit.
- Programmed inspections continue under the same triggers as before: heat advisories from the National Weather Service, complaints, and fatality investigations.
The substantive heat standard OSHA proposed in mid-2024, with mandatory water, shade, rest, written plans, and triggers at 80°F and 90°F, is still working through the rulemaking process. The NEP renewal is what’s preserving enforcement bandwidth in the meantime.
What contractors should actually do
Heat-related work stoppages have a habit of looking voluntary right up until OSHA shows up with a willful citation. The practical compliance baseline for construction in 2026 is straightforward, and most general contractors are already partway there.
A written heat illness prevention plan that names a responsible person and lists triggers. Documented acclimatization for new hires and return-to-work crews after extended absences. Trigger temperatures spelled out, even using the 80°F and 90°F language from the proposed rule, which is the standard OSHA inspectors are evaluating against in practice. Daily toolbox talks during heat advisories. Cool-down areas with shade and water within a short walk of every active work face.
The general-contractor liability is what gets ugly. On multi-employer sites, a sub’s heat illness can drag the GC into a willful citation if the GC’s plan was on paper but unenforced. ENR’s coverage of last summer’s enforcement push showed citations skewing toward sites where the GC had a plan in a binder and crews on the deck who’d never seen it.
What to watch
Watch the proposed substantive heat rule. If it survives current legal challenges and clears OMB, the 80°F and 90°F triggers in the NEP enforcement guidance become hard requirements rather than aspirational benchmarks. And watch for state-plan adoptions. California, Washington, Oregon, Minnesota, Maryland, and Nevada already have their own heat rules in some form. The federal NEP doesn’t preempt them. It runs on top.
For a sector that lost a record number of workers to heat last summer, five more years of programmed inspections is a floor, not a ceiling.
