Final answer:
Pulling out the tubing before shutting off the pump is crucial to avoid damaging the tubing by releasing any built-up pressure and preventing potential safety hazards.
Step-by-step explanation:
It is important to pull the tubing out of the pump before shutting it off to avoid damaging the tubing. This preventative action ensures that any built-up pressure within the tubing is released. If the pump is stopped while the tubing is filled with pressurized fluid, it may cause the tubing to burst or become misshapen, leading to damage that could be costly to repair and pose potential safety hazards. Additionally, keeping the tubing intact and free from damage ensures that the system can maintain proper function and efficiency.
