The heat wave gripping much of the country this week has put more than 160 million Americans under heat alerts, with cities setting all-time records — Salt Lake City hit 109°F on July 12. For a lot of the roles our graduates move into, that heat is not something you experience through a window. Construction sites, logistics yards, warehouse docks, and roadwork crews feel it directly, and heat is the deadliest weather hazard for outdoor workers. Many of the people in our construction and logistics tracks are on the front line of a week like this, so here is a practical playbook — for the employers who partner with us and the workers we place.
The three that prevent most heat illness
Federal safety guidance keeps coming back to the same three words, because they work: water, rest, shade.
- Water. Cool water, available at all times, with workers encouraged to drink small amounts often — roughly a cup every 15–20 minutes — rather than waiting until they are thirsty. Thirst already means mild dehydration.
- Rest. Scheduled breaks that scale up as the heat index climbs, taken before workers are struggling, not after.
- Shade. A genuinely cooler place to take those breaks — shade or air conditioning, not just the far side of a truck.
Acclimatization is the overlooked lifesaver
Here is the factor that surprises people: a large share of heat fatalities happen in a worker's first few days on the job, before their body has adjusted to the conditions. New hires, workers returning from time off, and everyone during the first heat wave of the season are the most at risk.
The fix is to ramp up exposure gradually — shorter stints in the heat early in the week, building to a full schedule over several days. For employers, that is worth naming directly to new crew members, and it is exactly the kind of onboarding detail that signals a workplace takes its people seriously. As we have written before, how you treat workers in tough conditions is a retention strategy, not just a compliance box.
Know the warning signs — and the emergency
Every supervisor and coworker should be able to spot heat illness:
- Heat exhaustion: heavy sweating, cold or clammy skin, dizziness, nausea, headache, weakness. Move the worker to a cool place, give water, loosen clothing, and cool them down.
- Heat stroke — a 911 emergency: hot, red skin; confusion; slurred speech; a person who stops sweating or passes out. Call for help immediately and cool the body aggressively while you wait. Heat stroke can be fatal or cause lasting harm in minutes.
A simple buddy system — pairing workers to watch each other for symptoms — costs nothing and catches trouble early, especially since confusion means the affected worker often cannot recognize their own danger.
Why this is workforce work
Keeping crews safe in extreme heat is not a side issue to employment — it is part of building the kind of jobs worth training people for. A worker who is protected on a 105-degree day is a worker who stays in the field, stays healthy, and stays in the workforce. As these heat waves grow more frequent, the employers who plan for them will be the ones who keep their people. That is good safety, and it is good business — and it is one more reason the readiness we build with our participants has to include knowing their rights and their limits on a dangerous day.
