What does the report indicate regarding the companies engaged in tactical activities during a working fire?

The report indicates that when companies are engaged in tactical activities during a working fire, they will typically remain at the scene for an extended period of time. This is because tactical operations in such scenarios often require sustained effort and coordination among various units to manage the situation effectively. Firefighting involves not just initial response but also ongoing activities like suppression, overhaul, and ventilation, which can take considerable time to complete.

Remaining on scene allows companies to fully address the fire, ensure safety protocols are followed, and manage any potential hazards. The requirement to stay at the scene is essential for effective incident management, as it helps to maintain control over the situation and allows for a coordinated response to any emerging challenges.

The other options suggest quick departures, returning to the station, or operating independently, which do not align with the nature of tactical firefighting and the necessity of a coordinated response during an ongoing incident.
