Texas Heat Rules After HB 2127: What Employers Still Owe

Did HB 2127 end heat protection for Texas crews?

No. HB 2127 ended local water-break rules. It did not end the employer’s duty to protect workers from heat. As of November 2026, OSHA still enforces heat hazards in Texas. It uses the General Duty Clause and the Heat National Emphasis Program.

This post is not legal advice. Check your own duties with your safety counsel.

The Texas Tribune reported that the law “will nullify ordinances enacted by Austin in 2010 and Dallas in 2015” that set 10-minute breaks every four hours. Those two city rules are gone. The federal rules on heat were never tied to them.

What rules apply to a Texas crew today?

Three layers apply, and only two are in force. Federal OSHA enforces heat hazards on every Texas jobsite. Texas has no state heat standard. A federal heat rule exists as a proposal only. The table shows the status of each layer as of November 2026.

OSHA’s heat page names Washington, Minnesota, California, Oregon, and Colorado as states with specific heat laws. Texas is not on that list.

What does OSHA still enforce in Texas?

OSHA enforces heat hazards through the General Duty Clause. That clause requires a workplace “free from recognized hazards that are causing or are likely to cause death or serious physical harm to employees,” in the words of OSHA’s heat page.

The Heat National Emphasis Program adds focus. OSHA revised it on April 10, 2026. It directs inspection priorities to 55 high-risk industries, indoors and outdoors. It runs for five years from its effective date. Read the full breakdown in our OSHA heat rules pillar.

Did a court change HB 2127?

A court challenge did not stop the law. A Travis County judge ruled it unconstitutional in August 2023. The Third Court of Appeals overturned that decision in July 2025, according to the Texas Tribune. We found no later change on the pages we checked.

The San Antonio city attorney’s office said the ruling did not bar future challenges. Treat the law as in effect and check again before you rely on this post.

What should a Texas employer do now?

Write your own rule. A city no longer sets your break schedule, so your written plan is the standard your crew sees. OSHA encourages “water, rest, and shade” as prevention. Follow that three-part frame.

1. Put cool water near the work and tell crews to drink before they feel thirsty.
2. Set break times by heat level, not by habit. Rest longer as heat stress rises.
3. Build a shaded or cooled rest spot. See our cool-down area setup guide.
4. Follow a heat acclimatization schedule for new and returning workers.
5. Train supervisors to spot heat illness. Heat stroke is a 911 emergency.
6. Write it down and review it each spring.

The Texas heat rules guide for employers walks through each step in detail.

Where does hydration fit in a Texas heat plan?

Hydration is one part of a written plan. Water comes first. OSHA says crews working two hours or more should also have fluids with electrolytes. JMAR Solutions builds hydration programs for high-risk crews, with onsite toolbox talks and training.

Rapid Restoration Drops are a dietary supplement. They replace electrolytes lost in sweat and support hydration. They do not replace water, rest, shade, or emergency care.

Why does a Texas heat plan matter so much?

Texas carries heavy heat risk. The Texas Tribune reported that “at least 42 workers died in Texas between 2011 and 2021 from environmental heat exposure, according to the U.S. Bureau of Labor Statistics.” It also noted that unions say this count misses cases recorded under another cause of injury.

A written plan is also strong proof of good faith if OSHA visits. It shows what you did, not what you meant to do.

What should a Texas heat plan put in writing?

Put the plan on one to two pages. Name an owner for each part. The table shows a base layout that works for most crews.

Keep sign-in sheets for every talk. If a heat advisory hits, log what you changed that day.
