Heat Stress Prevention: 5 Actions Employers Should Take During Extreme Heat

As temperatures climb across much of the United States, employers face a familiar but serious workplace hazard: heat stress.

While construction sites and agricultural operations often come to mind first, heat-related illnesses can affect employees in manufacturing facilities, warehouses, transportation operations, landscaping crews, utility work, and many other environments. Indoor workplaces without adequate climate control can present risks that are just as significant as outdoor job sites.

Heat exhaustion, dehydration, and heat stroke can develop quickly, particularly during the first major heat events of the season when employees may not yet be acclimated to working in elevated temperatures.

Although OSHA's proposed heat standard remains under review, employers should not wait for new regulations before evaluating their heat stress prevention efforts. Many of the measures being discussed at the federal level reflect long-established best practices that can help protect workers, reduce incidents, and maintain productivity during periods of extreme heat.

Why Leadership Should Pay Attention

Heat-related incidents can have consequences that extend far beyond employee health.

A single heat illness can result in:

  • Lost productivity
  • Increased workers' compensation costs
  • Project delays
  • Staffing challenges
  • OSHA inspections and enforcement activity
  • Reputational risk

As heat waves become more frequent and prolonged, organizations should view heat stress prevention as both a worker safety issue and a business continuity concern.

Leaders who proactively address heat-related risks are often better positioned to maintain operations, reduce injuries, and demonstrate a strong commitment to employee well-being.

Five Actions Employers Should Take Now

1. Review High-Risk Tasks

Identify jobs that require strenuous physical activity, heavy personal protective equipment, or extended exposure to hot environments. These tasks often present the greatest risk during extreme heat events and may require additional controls, supervision, or work-rest schedules.

2. Ensure Water Is Readily Available

Employees should have convenient access to potable drinking water throughout their shifts. Supervisors should actively encourage hydration and ensure workers can access water without disrupting operations or traveling long distances.

3. Provide Opportunities to Cool Down

Whether through shaded outdoor areas, air-conditioned break spaces, cooling trailers, or adjusted work schedules, employees need opportunities to recover from heat exposure before symptoms develop.

Consider scheduling physically demanding work during cooler parts of the day whenever operationally feasible.

4. Train Supervisors to Recognize Heat Illness

Front-line supervisors are often the first to observe warning signs of heat-related illness. They should be able to identify symptoms such as:

  • Dizziness
  • Confusion
  • Excessive sweating
  • Muscle cramps
  • Nausea
  • Fatigue

Supervisors should also understand when emergency medical attention is required, particularly when signs of heat stroke are present.

5. Evaluate Acclimatization Practices

New employees and workers returning from extended absences face a higher risk of heat-related illness. Gradually increasing workloads and monitoring employees during their first days back can significantly reduce that risk.

Acclimatization programs are often overlooked but remain one of the most effective heat stress prevention strategies available to employers.

A Quick Heat Stress Prevention Check

Leadership teams should be able to answer "yes" to the following questions:

✓ Do employees have access to drinking water throughout the workday?

✓ Are supervisors trained to recognize and respond to heat-related illnesses?

✓ Do workers have access to shaded or cooled recovery areas?

✓ Is there a process for monitoring weather conditions and heat exposure?

✓ Are new and returning employees gradually acclimated to hot work environments?

✓ Are emergency response procedures clearly defined and understood?

If any of these areas require attention, now is the time to address them before temperatures rise further.

Heat Stress Prevention Is More Than Compliance

While OSHA continues to evaluate a potential federal heat standard, the responsibility to protect workers from recognized heat hazards already exists.

Organizations that prioritize heat stress prevention can reduce injuries, improve workforce reliability, and better prepare for periods of extreme weather. More importantly, proactive planning helps ensure employees return home safely at the end of each workday.

UV Protection During Hot Days in the Sun

We may have already had a taste of fall weather, but high temperatures returned quickly to remind us that we’re not quite finished with summer just yet. Here are some good tips, tools, and resources to help you better protect your skin from harmful sunlight while enjoying days in the heat. What are UV Rays? UV stands for ultraviolet, which is a type of light that comes from the sun. There are two main types of UV rays that can reach us: UVA and UVB. While sunlight helps us stay warm and can be good for getting vitamin D, too much UV light can be harmful to our skin and eyes. Why is it important to be “Sun Safe”? Excessive exposure to UV rays can cause sunburns, a painful reddening of the skin.  Over time, UV exposure increases your risk for skin cancers like squamous cell and basal cell carcinomas, and cutaneous melanoma.  UV light can also damage your eyes and can lead to cataracts and macular degeneration. How Can You Stay Safe? Wear Sunscreen: Always put on sunscr...

Worker Burned After Tank Explodes — Company learns why machine-specific LOTO procedures are needed

** This is a true story. Names and certain details were changed to preserve anonymity. A busy R&D company was working on a sustainability project involving alternative fueling options for a piece of equipment at their facility. The project was long awaited, had underwent much research and was finally at the testing stage which involved a new fuel source being pumped into a propane tank that was already onsite. The project manager, Steve, and maintenance man, Rob, were in charge of oversight on the fueling of the propane tank. When the Job Began With no machine-specific procedure established, Steve began by locking out the lines of the tank based off of his knowledge and proceeded with loading the new fuel. However, as luck would have it, the truck dispensing the fuel was having issues with the pump stalling, so, after multiple attempts, Steve and the truck’s driver decided to call it quits. The driver disconnected, bled the lines, and left. Before leaving, Steve told Rob how t...
