Heat Wave Survival Tips From a Death Valley Ranger, Volcano Hiking Guide and Forest Firefighter

With a large, slow-moving heat dome extending from the central Plains to the East Coast, extreme temperatures across the United States have prompted professionals who work outdoors to share practical approaches to staying functional. The article describes conditions through on-the-ground accounts, including Hailey Simko, a 21-year-old forest firefighter responding to the Babylon Fire in southeast Utah. It also includes guidance from Grady Ladner, 34, a roofer in Ridgeland, Mississippi, who said roof temperatures can reach around 140 degrees when the ground is about 95, with humidity making conditions especially difficult. Ladner’s crew of seven to eight reportedly uses more than 60 bottles of water per day and takes shade breaks every hour for 10 to 15 minutes. A food-truck owner and chef in Austin, Texas, Charlie Rajeh, said truck interiors can exceed 110 degrees while cooking, and that fans are limited in effect. The piece frames the advice as adaptations to heat, hydration, and scheduled cooling breaks rather than technical changes to vehicles.
