With the sun beating down on a Friday morning, firefighters from Flagler County and Palm Coast are called to a home on Elder Street in Bunnell.

During these scorching days, Flagler County Fire Chief Don Petito told News 13 you'll see more than the normal number of crews on these calls.

“We do double up on the crews and we get them in and we get them out fast. Usually, the first ones in, we want them to be the first ones out and then we start rotating other crews in,” said Petito.

We checked with other departments and they all have one thing in common: A safety officer is on scene, keeping a close eye on the firefighters.

A spokesperson with the Daytona Beach Department tells us crews "spend more than ample time in rehab stations to ensure that our crews are fully hydrated before returning into a fire."

In the case here in Bunnell, a paramedic unit was nearby with the AC cranked up so anyone needing extra help cooling down gets it.

Because as Chief Petito explains it, “once their core temperature gets over a certain spot, you know they become useless because the body temperature doesn't allow you to do the work that you used to do.”

Firefighters are also told to skip the caffeine and alcohol a day before they begin their shifts...two things that help speed up dehydration while they're on the job.

Also, when they're on the job any training they do is done inside and out of the outdoor heat.

Chief Petito adds, the safety message is getting through as firefighters are watching for warning signs among themselves.

“Every firefighter wants to keep going. They want to be the one in the action. But I think the heat the way it is, it's more commonplace now because they feel it coming on.”
