Heat illnesses to watch for

  • Heat stroke (emergency): confusion, fainting, seizures, very hot skin, or core temperature near or above 105°F. Call 911, move to a shaded or cool area, and cool with water or ice.
  • Heat exhaustion: heavy sweating, headache, dizziness, nausea. Stop work, rest in a cool place, and hydrate.
  • Heat cramps & heat rash: painful muscle spasms and irritated skin—often early red flags that conditions are unsafe.

Who is most exposed?

Construction, landscaping, delivery and utility work, airport ground crews, agriculture, kitchen and warehouse jobs without adequate cooling, and anyone wearing heavy PPE face elevated risk. New or recently returned workers are at the highest risk because the body needs time to adapt. OSHA and NIOSH recommend the “20% rule”: start with about 20% of typical heat exposure on day one and increase by no more than 20% each day, with full acclimatization often taking 7–14 days.

Employer responsibilities (the basics)

Even without a finalized federal heat standard, employers must keep workplaces free of recognized hazards. Good programs typically include:

  • Access to cool water, rest breaks, and shade or cooling
  • Training to recognize symptoms
  • Acclimatization plans for new and returning workers
  • Emergency procedures
  • Active monitoring when heat risk is elevated

How hot is “too hot”?

The OSHA–NIOSH Heat Safety Tool uses the heat index (temperature + humidity) to assign risk levels and recommended precautions. As the heat index rises into higher risk categories, employers should increase water and rest frequency, provide shade or air-conditioned break areas, and consider changing schedules or duties.

What’s happening with the law?

  • Federal: OSHA has proposed a nationwide heat rule for outdoor and indoor work; the public hearing concluded July 2, 2025, with post-hearing comments open through September 30, 2025. A final rule was not in effect when the original article was published, but the proposal outlined requirements such as water, shade or cooling, breaks, training, and acclimatization.
  • New Jersey: Lawmakers had debated creating a state heat standard, but as of July 2025 no statewide rule had passed and several bills were pending.

Practical steps for workers

  • Speak up early if you or a co-worker shows symptoms—heat stroke is a medical emergency.
  • Hydrate often with small, frequent sips and take rest breaks in shade or a cool area.
  • Use the buddy system during high-risk periods.
  • New and returning workers should follow acclimatization guidance, including the 20% rule.
  • Document conditions, including temperatures, schedules, and a lack of water, shade, or breaks.
  • Report safety concerns to a supervisor or safety representative; if ignored, you can file an OSHA complaint, and retaliation for reporting safety issues is unlawful.
