Great post from our colleagues Chorley Fire Station giving an insight into our Breathing Apparatus training and the conditions we train for.
๐ฅ Breathing Apparatus Training โ Understanding Flashover ๐ฅ
On-call firefighters from across the county are currently undertaking their Initial Breathing Apparatus (BA) training โ a course that all operational firefighters complete as part of their training and development.
As part of the course, firefighters are taught how to recognise, respond to and mitigate the signs of a flashover โ one of the most dangerous phenomena firefighters can encounter at a fire.
๐ฅ So, what is a flashover?
A flashover occurs when the heat within a compartment fire becomes so intense that combustible materials and gases throughout the room reach their ignition temperature almost simultaneously. This can result in the fire rapidly transitioning from a localised fire to full-room involvement in a matter of seconds.
Firefighters are trained to recognise the warning signs of an impending flashover, including increasing heat, changes in smoke conditions and the behaviour of the fire. Through effective firefighting techniques, including correct use of the branch, ventilation considerations and cooling of hot gases, crews can work to reduce the likelihood and severity of flashover.
BA training is a vital part of ensuring our firefighters have the knowledge, skills and confidence required to operate safely in some of the most challenging environments they may encounter.
