States Race Ahead of OSHA on Cold-Weather Worker Safety

States Race Ahead of OSHA on Cold-Weather Worker Safety

Seven states already require employers to protect workers from heat stress. Now, with federal OSHA still working on its heat standard, state lawmakers are pushing into a new area: cold weather.

In 2025, 18 state lawmakers introduced workplace temperature protection bills — more than double 2024’s count. None passed yet, but expect 2026 to be different.

Illinois introduced the Workplace Extreme Temperature Safety Act, which would have required warm non-caffeinated drinks and climate-controlled rest areas when outdoor temperatures dropped near freezing, with protections kicking in below 40°F outdoors and 65°F indoors depending on physical exertion. The bill cleared a House committee. Rhode Island’s SB-0586 passed the Senate before stalling, setting temperature thresholds below 32°F and adding warehousing, construction, and transportation-specific requirements.

Minnesota and Washington are the only states currently enforcing cold-related safety rules through their state OSHA plans. Minnesota requires a minimum air temperature of 60–65°F indoors and has issued 11 cold-condition citations since fiscal year 2020. Washington applies a general extreme-temperature rule that covers cold conditions, with a specific cold-stress rule narrowly aimed at firefighters.

For multistate employers, what’s coming is messy:

* A patchwork of varying triggers (35°F here, 32°F there), varying break and beverage requirements, and varying recordkeeping obligations.

* Increased compliance costs as you train and oversee local managers on policies that differ by site.

* More exposure under state OSHA plans, which can go further than federal OSHA.

Three things to do now:

1. Map your state OSHA exposure. Know which sites are in OSHA-plan states versus federal jurisdiction states.

2. Watch your 2026 legislative trackers. Illinois will likely refile. Other blue and purple states are expected to introduce companion measures.

3. Build a flexible cold-stress program now. Even where there’s no state mandate, the federal general duty clause already requires protection from hazards “likely to cause death or serious physical harm” — and OSHA inspectors do cite for cold exposure.

If OSHA actually issues a federal heat standard in 2026, expect cold-weather standards to follow within a few years. The states are signaling where this is heading.

Is your safety program ready to handle a patchwork of state-specific temperature rules?
