Tonight Mahwah Firefighters went to the Bergen Fire Academy for flashover training. Simply put a flashover is when the gases inside of burning room suddenly ignite. This is an extremely dangerous situation for firefighters to be in and may only leave them with a few seconds to get out of the area. This can be simulated at the academy and allows firefighters to learn the signs that one is imminent and what to do in that situation. The video below shows some of the training that took place tonight.
