Rural Metro Fire San Tan Valley, the fire and emergency medical provider for the San Tan Valley area, is warning residents that everyday surfaces around the home can reach burn-causing temperatures during Arizona's summer heat.

In a video posted to the department's Facebook page, public information officer Shawn Gilleland took thermometer readings around a home to show how hot common items get in the sun — and each reading landed well above the point where skin can burn.

Inside a parked car, Gilleland measured 178 degrees Fahrenheit. A closed car traps heat and climbs far above the outside air temperature. At that level, the interior is dangerous within minutes for a child or pet left inside — even a short errand is too long.

Water from a garden hose measured 129 degrees. Water sitting in a hose heats up in the sun, and the first blast can be hot enough to scald — especially a child's skin, which burns more easily than an adult's. Gilleland noted a small child was burned by garden hose water a few years ago. Let the hose run until the water turns cool before letting anyone play in it or filling a kiddie pool.

Concrete measured 131 degrees. Pavement holds heat long after the sun peaks. At that temperature, it can burn bare feet and a pet's paw pads. If the ground is too hot to hold your hand against, it is too hot for a dog to walk on.
