The U.S. Fire Administration has announced the line-of-duty death of a Tennessee volunteer firefighter who fell ill and died during training.

Firefighter Derrick Ryan Webb, 31, was preparing for a training drill at the Hardy's Chapel fire station in Cookville when he was found unresponsive in the apparatus bay with his turnouts and SCBA beside him.

Colleagues immediately initiated CPR, but Webb was pronounced dead upon arriving at a hospital.

According to a Facebook post, Webb was a captain, but the USFA did not confirm his rank nor state how long he was with the department.

Cookville is a town of less than 35,000 people in Putnam County about 80 miles east of Nashville.
