What should responders remember when ventilating an upper-story window using an aerial device?

When ventilating an upper-story window using an aerial device, it is crucial for responders below to stay clear. This is because ventilation operations can pose several risks, including the possibility of falling debris, smoke, or heat that may escape from the window being ventilated. By keeping a safe distance, responders below can avoid injury and ensure that they are not in harm's way while the operation is underway.

While positioning the aerial device directly above the window, limiting the nozzle operation to one responder, and inspecting for potential hazards are important considerations as well, the primary concern during active ventilation is to maintain a safe environment for all personnel. Ensuring that responders below are clear is essential for safety during an operation that may involve unpredictable conditions and rapid changes in the environment.
