When performing a school bus extrication, it's always a good idea to make use of existing openings when possible. Cutting through bus material can be a time consuming and risky process, keeping passengers trapped in the bus longer and therefore increasing risks.

For example, window frames can be easily cut to instantly create large openings for removal of passengers. If catastrophic damage prevents shortcuts such as this, the roof is generally the easiest place to cut a large hole for extrication, particularly when the bus is on its side.
