ABSTRACT

Fires and Exposures   [open pdf - 792KB]

"Exposures are defined as anything in the immediate range of a fire that is not burning but could start burning if the fire is not contained. When enough oxygen is available, combustible material burns once its temperature reaches its ignition temperature. Preventing exposure fires requires protecting the objects from heat spread and thus from reaching their ignition temperatures. This is one of the most critical jobs in firefighting, as protecting exposures helps contain the fire and prevents fire spread. After rescuing individuals, protection of exposures is the highest priority for firefighters. Exposures can be internal or external. Internal exposures are within the property, such as a room or floor of a building. External exposures include other buildings, vehicles, and outside objects or vegetation such as trash, dumpsters, trees, or crops. External exposures are typically known as 'exposure fires.' These exposure fires and the source fires that cause them are the topic of this report."
