With 100+ temperatures, outdoor surfaces are heating up. Here’s how to be safe
As temperatures soar to 100 degrees Friday and Saturday, Fourth of July plans won’t be the only thing heating up this weekend. Such extreme temperatures can make surfaces like pavement and playgrounds hot to the touch.
The National Weather Service issued a heat advisory Thursday, in place until 8 p.m. If the heat holds, Saturday could set a new record for the hottest Fourth of July in more than 30 years.
Contact burns, which make up 7 to 9 percent of all reported burns according to the American Burn Association, happen not only from a hot pan or grill. They can result from materials like pavement or car seats that have baked in the sun, although rare.
The Charlotte Observer breaks down how these surfaces heat up so you and your family can stay safe this holiday weekend.
Limit time on pavement
Pavement can reach temperatures of 125 degrees even when its in the 70s, according to the American Burn Association.
When temperatures surpass 90 to 100 degrees, the surface of asphalt can reach 140 to 170 degrees, according to the City of Charlotte. Asphalt is made with a petroleum-based binder that softens as temperatures heat up — concrete still gets hot, but doesn’t have this softness.
According to the National Institute of Standards and Technology, people begin to feel pain when their skin reaches a temperature of 111 degrees — a first degree burn can occur at 118 degrees.
The American Burn Association advises supervising young children, whose skin burns quicker, and pets.
Animals’ bodies heat up fast because they are close to the ground, the American Society for the Prevention of Cruelty to Animals reminds pet owners. People should keep walks with their furry friends to a minimum and stay off asphalt when possible.
In addition to being wary of pets’ paws, people should watch for signs of heat stroke: In animals, this includes excessive panting, drooling and weakness. Flat-faced animals, like pugs and Persian cats, cannot pant as effectively and are more susceptible to heat stroke.
Monitor motor vehicles
Dark features of a car, such as the seat or steering wheel, can reach temperatures over 180 degrees, according to the National Weather Service. They’re also able to transfer heat, warming up the air trapped inside a car. In 90-degree heat, it takes just 10 minutes for a car’s internal temperature to reach 100 degrees — and within an hour it can reach over 130 degrees.
Even in the winter, it is never safe to leave children, pets or people with a disability in a locked car, the National Weather Service reminds people on its website.
High heat can cause problems for vehicles including shortened battery life, weak tires and overheating engines, according to the American Automobile Association. Drivers should park in the shade and take precautions when they know temperatures are rising such as testing batteries and checking tire pressure.
Harley-Davidson Insurance advises similar inspections for motorcyclists and suggests that riders invest in a UV-protective cover.
Pay attention at playgrounds
Playgrounds pose a particular problem in the heat. Many of its materials, not just metal but also plastic and rubber, can lead to burns. As with asphalt and car interiors, dark surfaces heat faster.
The National Program for Play Area Safety advises children to touch a surface before playing on it.
Children should also hydrate and play in shaded areas if available.
