Let’s be honest, we’ve all felt it. That first truly scorching day of the year when the heat just smacks you in the face the second you step outside. For most of us, it’s an inconvenience. We crank up the AC, grab a cold drink, and complain a little.
But what if your job was out there in that heat? What if you were on a construction site, a farm, or a rooftop for eight hours a day?
Suddenly, that heat isn't just an inconvenience. It’s a serious danger. And for employers, it's becoming one of the biggest risks we need to manage. This isn't just about climate change chatter; it's about protecting real people and, frankly, protecting your business from some very real consequences.
The Numbers Don't Lie: This Is a Growing Crisis
It’s not just your imagination—it’s getting hotter. The National Oceanic and Atmospheric Association (NOAA) has been keeping records for 131 years, and they clocked 2025 as the fourth hottest year on record for the contiguous U.S. Some states, like Nevada and Utah, even broke their own all-time records.
This isn't just a weather report. It has a direct, and tragic, human cost. A study in the medical journal JAMA tracked heat-related illnesses and found something truly alarming. Between 1999 and 2023, the number of heat-related deaths in the U.S. shot up by 117%. We went from just over a thousand deaths in 1999 to more than 2,300 in 2023.
Think about that. The danger is literally more than doubling. We’re not just talking about feeling a little woozy. We’re talking about heat exhaustion, heat stress, and life-threatening heat stroke.
So, What Are the Rules? And Are They Enough?
Okay, so the government knows this is a problem, right? Yes, and there are rules in place. The main one is OSHA’s “general duty clause.” In simple terms, it’s a federal standard that says employers have to provide a workplace free from recognized hazards—and extreme heat is definitely one of those.
But here’s the thing: that’s a baseline. It’s the absolute minimum.
Some states are way ahead of the curve. Places like California, Nevada, Washington, and Colorado have their own, much stricter requirements for preventing heat illness. If you operate in one of those states, you need to be on top of those specific rules.
Now, there’s a bit of a worrying trend. Michele Hibbert, a Senior VP at Enlyte, pointed out that OSHA has faced some funding challenges lately. This has led to fewer on-site inspections and more focus on just reviewing paperwork. As she put it, “we may miss some violations at the end of the day because of that.”
That’s a pretty big deal. It means you can't just wait for an inspector to show up. The responsibility to be proactive is falling more and more on employers themselves. OSHA has tried to step up with a National Emphasis Program on heat hazards, which has led to more inspections and citations, and they're even working on a new, more specific rule. But rules on paper don’t save lives. Action does.
A Plan on a Shelf Is Just a Piece of Paper
I was talking with Greg Stefan, who’s the SVP of Risk Control for Arch Insurance, and he hit the nail on the head. He said the biggest problem isn't that companies don't have a plan. The problem is in the execution.
“An employer… needs to start with fully assessing the risk,” he explained. “Do they truly understand the exposures that their employees are facing?”
It’s so true. You can have the most beautiful, laminated heat safety plan in the world, but if it’s just sitting in a binder in the office while your crew is out in 95-degree heat, it’s useless. The "nuts and bolts" of a good plan are mostly common sense, but the follow-through is where things often fall apart.
And it can't be a one-and-done thing. Melissa Martinez, a Clinical Operations Manager at Enlyte, stressed that training has to be constant. It’s not about a single safety meeting in May. It’s about building a culture where everyone is looking out for each other, all summer long.
What Does a Good Plan Actually Look Like?
So, what are the practical, on-the-ground things you should be doing? It’s not as complicated as you might think. Philip Maddox, the Technical Director for Workers Comp at Nationwide, broke it down into simple temperature triggers.
Think of it like a tiered response system.
When the heat index hits 80°F:
- Water is non-negotiable. Have water stations readily available, maybe every 300 feet or so on a large site.
- Provide shade. This could be shade trailers, pop-up canopies, or designated indoor break areas.
- Focus on acclimatization. You can't take someone who's been working in a 70-degree office and throw them onto a hot roof for 8 hours. New workers, or those returning from time off, need to gradually build up their tolerance to the heat.
When the heat index climbs to 90°F or higher:
- Mandate paid breaks. Don’t make your team choose between their health and their paycheck. Enforce cool-down breaks in the shade.
- Supervisors need to be vigilant. Foremen and managers should be actively checking on their crews, looking for signs of heat stress like fatigue or confusion.
- Have an emergency plan. Is contact info for EMS clearly posted? Does everyone know the address of the job site?
- Bring in the tech. This is where things like cooling vests, cooling towels, and even wearable tech for lone workers can be literal lifesavers. A wearable can track a worker's location and vitals, which is critical if they're working alone.
Joshua Martinez from Gallagher Bassett echoed this for the construction industry, adding ideas like rotating tasks so the same person isn’t doing the most strenuous job all day. Simple, effective, and it shows you care.
The Ripple Effect: Heat Causes More Than Just Heat Stroke
Here’s something that often gets overlooked. The danger of heat isn’t just about someone collapsing from heat stroke. Extreme heat messes with your body and your brain. It impairs judgment, slows reaction time, and causes fatigue.
What does that lead to? More accidents.
A Workers’ Compensation Research Institute (WCRI) study found that when daily temps go above 90°F, the probability of a work-related accident jumps by five to six percent. And it’s often traumatic injuries, like falls. It’s easy to imagine: a roofer gets a little dizzy from the heat, missteps, and falls. The cause of the claim is the fall, but the root cause was the heat.
Matt Zender at AmTrust Financial shared a perfect example. He’s seen claims with HVAC contractors working on hot roofs in polluted areas, where the combination of heat and bad air quality creates a perfect storm for an accident. The good news, as he points out, is that education goes a long way. These are common-sense solutions.
Being Safe Isn't Just the Right Thing to Do—It's Smart Business
In a tight labor market, your reputation as an employer is everything. Jayson Taylor, Head of Casualty at MSIG USA, put it simply: “People want to go work where they hear good things are going on and they’re treated well.”
Being known as the company that takes care of its people, that doesn’t cut corners on safety? That’s a massive competitive advantage. It helps you attract and keep the best talent.
Ultimately, this all comes back to a simple idea that Dorothy Doyle from Liberty Mutual shared. Viewing safety as a core business priority, not just a box to check, makes everything better.
“Efficient operations are safe operations,” she said. When you prioritize safety, you see improvements in quality, delivery time, employee engagement, and yes, profitability. Failure to act doesn't just open you up to lawsuits and fines; it damages your reputation and makes it harder to keep good people.
So as the temperatures continue to climb, let’s stop thinking of heat as just weather. It's a critical safety issue and a core business challenge. A little planning, a lot of water, and a genuine culture of care can make all the difference. It can save a life, and it can strengthen your entire business.
