OSHA Updated the Heat NEP for 2026 — Here's What Contractors Should Do Now

OSHA updated its Heat National Emphasis Program on April 10, 2026, replacing the prior April 2022 heat directive with a revised five-year program for outdoor and indoor heat-related hazards.

Here's the short version: heat enforcement did not go away. OSHA says the revised NEP is effective immediately, focuses on high-risk industries and workplaces, and keeps heat hazards inside the agency's inspection, outreach, and compliance-assistance priorities.

What OSHA Changed in the 2026 Heat NEP Update

When OSHA launched the NEP in April 2022 (directive CPL-03-00-024), it gave inspectors a structured playbook for going after heat hazards:

• Programmed inspections of high-exposure industries — construction, agriculture, landscaping, warehousing — without waiting for a complaint
• Follow-up inspections for employers with prior heat citations

That playbook was replaced by the revised NEP of April 10, 2026. OSHA indicated the revised program will remain in effect for five years from its effective date, unless modified again.

What This Means for Contractors

The important shift is not 'heat enforcement ended.' It is 'OSHA refreshed the playbook.' Contractors should expect heat hazards to remain a live inspection issue.

General Duty Clause citations still apply. Under Section 5(a)(1), OSHA only needs to show that heat is a recognized hazard in your industry (it is) and that you didn't take reasonable steps to protect workers. Courts have upheld these citations repeatedly.

The proposed permanent federal heat rule remains separate. The NEP is an enforcement emphasis program, not the same thing as a permanent federal heat standard.

More states are moving on their own. Virginia's legislature passed SB288/HB1092 in 2026, directing adoption of a heat illness standard by May 1, 2027. Other states are actively considering heat-specific requirements.

The Contractor Risk

This is where contractors get hurt: assuming an NEP update means 'nothing to document.'

One heat-related serious injury, one OSHA inspection, one willful citation — that's a six-figure bill before your lawyer picks up the phone.

But the gap between "has a program" and "doesn't" just got bigger. In July 2025, OSHA expanded its penalty reduction guidelines:

A small contractor with a documented heat program, clean history, and a supervisor who corrects hazards on-site could see a $16,550 citation drop to roughly $1,700. That's the reward for having your house in order.

A contractor with nothing written down? Full exposure.

4 Things to Do Before Summer

These apply whether you're under federal OSHA only or in a state-plan state.

1. Write your heat illness prevention plan — today.

If it's not in writing, it doesn't exist in OSHA's eyes. Your plan needs to cover:

• Temperature triggers — 80°F for starting protective measures, 90°F for high-heat protocols
• Water access — at least one quart per worker per hour, cool, potable, within close reach
• Shade and cool-down areas accessible from every work area
• Rest breaks tied to heat index levels — not just "when workers feel hot"
• Acclimatization for new hires and workers returning after time off
• Emergency response steps — what supervisors do when someone shows symptoms

2. Train every supervisor. Document it.

OSHA's Safety Champions Program — free to join — provides a documented framework that demonstrates good-faith compliance. This directly affects penalty calculations if you're ever inspected. A sign-in sheet for heat training is basic evidence. Use it.

3. Know your state's specific requirements.

If you work in California, Oregon, Washington, or Maryland, you have legally enforceable obligations that predate and outlast the NEP. Get the actual regulation for your state, not a summary. Use our OSHA Penalty Calculator to see what violations cost in your state, or browse state-by-state compliance guides for your trade.

4. Match your plan to the actual season.

Heat season is starting earlier every year. Don't wait until June to dust off last year's procedures. Review and distribute your plan before the first hot week hits.

Bottom Line

OSHA's April 2026 update keeps the Heat NEP active. It doesn't remove OSHA's authority, state enforcement, or the penalties that come with heat citations.

Contractors with a written heat illness prevention plan, documented supervisor training, and state-specific compliance are better positioned now than three years ago — because the penalty reduction program actively rewards them.

Contractors without a program are gambling with peak-season risk.
