What should an OV for the 1st due truck do at a taxpayer?

In the context of firefighting operations, particularly when dealing with a taxpayer building, the role of the Outside Vent (OV) firefighter is crucial to ensure the safety of both victims and fellow firefighters. The correct action for the OV in this scenario is to check the sides of the building and ventilate the rear.

By checking the sides of the taxpayer, the OV can gather essential information about the conditions of the fire, including any potential points of egress for trapped occupants and the presence of fire extension. Ventilating the rear is equally important to release heat and smoke from the interior of the building, which aids in improving visibility and reduces the overall temperature inside, creating safer conditions for the interior crews working to rescue any occupants and extinguish the fire.

This strategy aligns with the goals of effective firefighting tactics, emphasizing ventilation to support operations and enhance overall safety. Other choices, while relevant to various firefighting strategies, do not fully address the immediate priorities required during a fire in a taxpayer building.
