When employing back scanning, what should be the main focus?

When employing back scanning, the main focus is on recognizing incoming fire conditions. Back scanning is a crucial technique used by firefighters to maintain situational awareness of the environment behind them while they are engaged in firefighting or rescue operations. This practice allows crew members to identify any rapidly changing fire conditions or additional hazards that may develop, which could affect the safety of both the firefighters and any victims they may be attempting to rescue.

By concentrating on incoming fire conditions, firefighters can anticipate potential threats, make informed decisions, and take prompt action to ensure their safety and the success of their operations. Observing changes in smoke color, movement, and the behavior of flames are critical in assessing whether the situation is worsening and if a retreat or evacuation is necessary. This proactive approach can be vital in avoiding entrapment or injury, thus underscoring the importance of this focus during back scanning.
