What is a ceiling hook primarily used for?

The ceiling hook is primarily used for pushing and pulling ceilings down, which is crucial during fire rescue operations. In scenarios where there is suspicion of hidden fire or when the integrity of the ceiling is compromised, firefighters use a ceiling hook to gain access to the space above the ceiling. This tool helps to test for fire extension or to create a ventilation path by pulling down or pushing up sections of the ceiling safely.

This function is vital for ensuring that any potential fire spread is addressed and that firefighters can see what may be hidden in the ceiling void. The design of the ceiling hook, with its sturdy, elongated shape and pointed tip, allows for effective maneuvering in tight spaces, making it an indispensable tool for firefighters during their operations.

Other choices do not align with the primary purpose of a ceiling hook; they either represent tasks that require different tools or are unrelated to the essential functions firefighters need during intervention.
