Heat safety laws are no longer a future concern for employers. Eight states already enforce their own heat rules, Virginia has signed legislation to build one by 2028, and Arizona has issued formal task force recommendations for outdoor crews. Employers who ignore this shift risk fines and, worse, injured workers.
This piece explains what these heat safety laws actually require and where FR workwear fits into that compliance picture.
Which States Already Have Heat Safety Laws?
California, Colorado, Maryland, Michigan, Minnesota, Nevada, Oregon, and Washington already enforce heat safety laws for workers.
Each of these states asks employers to provide water, shade or a cool rest area, and scheduled breaks once temperatures cross a set threshold. Some go further and demand a written heat illness prevention plan.
Virginia will join this group soon. Its legislature passed heat illness legislation this year, and the state's Safety and Health Codes Board must finalize a full standard by May 2028.
- Water access at all times during a shift
- Shade or a climate-controlled break area
- Rest periods tied to heat index levels
- Training on spotting heat illness symptoms
Why Did Arizona Add Its Own Heat Safety Laws?
Arizona moved because outdoor workers there face some of the highest heat exposure in the country.
The state's Industrial Commission approved a set of heat safety recommendations for employers. These are guidelines rather than an enforceable law right now, but they signal where Arizona is heading.
Employers in Phoenix, Tucson, and other high-heat cities should treat these recommendations seriously. Heat safety laws in Arizona are likely to become mandatory once the state finalizes its rulemaking process.
How Do These Heat Safety Laws Affect What Workers Wear?
Heat safety laws directly affect clothing choices because heavy or non-breathable fabric raises the risk of heat illness.
A worker wrapped in stiff, heavy gear retains more body heat. That works against every rule these laws are trying to enforce, from rest breaks to hydration schedules.
FR clothing has to walk a fine line here. It must protect against flash fires and arc flashes while staying light enough that it does not become a heat hazard on its own.

Is Your FR Workwear Compliant With Current Heat Safety Laws?
Your FR workwear is compliant if it meets the fire-resistance rating required for the job and does not conflict with the rest, water and shade rules these laws set.
Compliance is not only about the fabric's fire rating. A shirt can pass NFPA certification and still trap heat if the weave is too thick for the job site's climate.
Employers operating in Virginia, Arizona, or any of the eight states with active heat safety laws should review both the certification and the breathability of their FR gear together, not separately.
- Check the fabric's NFPA 2112 or NFPA 70E rating first
- See if the weight actually fits your local climate
- Look for a moisture-wicking or vented build
- Back it up with a written heat illness plan
What Happens If an Employer Skips Heat Safety Laws?
Skipping heat safety laws can land an employer with fines, lawsuits, and a workforce more prone to injury.
States that enforce these rules can issue citations much like any other OSHA violation. Virginia's new law goes a step further and lets workers take legal action to recover damages themselves.
There is a productivity cost too, separate from any legal one. A crew dealing with heat illness slows down long before a complaint ever gets filed.
Where Can You Find FR Workwear Built for Hot Climates?
Specialized safety apparel retailers carry FR clothing designed specifically for high-heat regions.
NKE Safety Apparel stocks FR shirts, jackets, and pants built with lighter blends suited to states facing new heat safety laws. Their range works well for crews in Arizona, Virginia, and other regions where summer heat is a daily concern.
Local safety supply stores in high-heat cities are also worth checking, since some stock region-specific fabric weights that online catalogs may not highlight clearly.
