Headfirst controls time outside for campers

It's all fun until the mercury starts rising.

And when you run a summer camp with around 600 children, you do not mess with the heat.

“Parents are trusting us with their most valuable trophy," says Headfirst Camp site leader, Gregg Huckstadt. “It’s 1,000 percent important to us that we're taking care of every child like they're our own.”

And to that end, the camp maintains a tightly-controlled environment, with water and sunscreen breaks every 10 minutes. And campers can only be out in the sun for 25 minutes at a time, as a heat gun shows that although it’s 98 degrees in the shade, it’s a staggering 143 out in the field.

Those running the camp are keenly aware of the dangers involved with the heat, so after 1 p.m., children are banned from being out in the sun altogether.

Unlike these campers, construction workers don't have a choice when it comes to being outside. The heat not only beams from above, it radiates from under their feet – and it can get brutal.

The heat gun showed us the temperature of the newly-laid asphalt at their work site was around 250 degrees. And that's an easy day. On a residential road, the concrete mix they use doesn't radiate as much heat.

Construction engineer Jeff Wright compares the two: “Residential area is a lot less hot compared to being in the middle of the interstate... no trees, no shade.”

Working six days a week, Wright and his fellow construction workers know the drill.

Wright: “Water, water, water. Just drink a lot of water and stay hydrated…shade and take a break. That's all you can really do to eliminate the heat.”
