People working outdoors should reschedule strenuous activities to early morning or evening, wear light-weight and loose-fitting clothing and drink plenty of water.
Enclosed cars left in the sun have the potential to become much hotter than the already scorching outdoor temperatures.
Mesquite Police in Nevada used the occasion to illustrate the deadly heat potential of hot cars on the department’s Facebook page, with one car’s interior temperature reading approximately 188 degrees Thursday.
It only takes a matter of minutes for a vehicle’s interior temperature to reach lethal levels, according to the National Weather Service.
Young children and pets should never be left unattended in vehicles under any circumstances. They can suffer brain damage or die from heatstroke in as little as 15 minutes.
Anyone who observes a child or pet left alone inside a parked vehicle is encouraged to call emergency services.
