BATON ROUGE, La. (BRPROUD) – Some training courses take place in comfortable, air-conditioned classrooms where it’s all too easy for attendees to close their eyes and drift off for a few minutes.

And then there’s the training that’s required to be a firefighter with the Baton Rouge Fire Department (BRFD).

During the Fire Emergency Training Academy BRFD recruits attended Thursday (September 8), there was no sleeping in class. This was largely due to the fact that the “classroom” consisted of a tiny trailer designed to burst into flames.

On BRFD’s official Facebook page, the reason for this specialized training was explained.

BRFD said the recruits went through the ‘Flashover Trailer’ to learn how to recognize the warning signs that a ‘flashover’ is poised to occur.

If you’re wondering what a ‘flashover’ is, BRFD defines it as a “thermally-driven event during which every combustible surface exposed to thermal radiation in a compartment or enclosed space rapidly and simultaneously ignites.”

Essentially, it’s when the energy of a fire radiates back to the contents of an area, causing flames to suddenly consume the entire area.

Flashovers can catch firefighters off guard because they occur very quickly and the warning signs are easy to miss.

This is why BRFD said of Thursday’s training, “This is an extremely important training for firefighters. They must be able to recognize the warning signs a flashover is about to occur.”

Going through the Flashover Trailer is only one aspect of the training recruits must complete in their journey as BRFD Firefighters.

As recruits make their way through each part of their training, they’re taking in valuable information that can keep them as safe as possible while they serve the Baton Rouge community.
