(KSL News) Local officials are warning about just how quickly carbon monoxide can become deadly.
The Kearns Fire Department and HAZMAT team gave Eyewitness News a demonstration. They put a small generator in a shed for 15 minutes.
After five minutes, the carbon monoxide levels were high enough to give anyone breathing the air a headache. After 15 minutes, it was a severe headache.
HAZMAT technicians say being exposed to the generator for eight hours could be fatal. Bigger appliances would kill much quicker.
Officials also warn carbon monoxide levels on propane or fuel-based space heaters can be just as deadly.
