Which is the correct order of actions before tow operations can commence?

The correct sequence of actions before tow operations can commence emphasizes safety and operational readiness, making it crucial for ensuring that all preparations are thoroughly completed. Closing all doors ensures that any potential hazards from open compartments are minimized, which is essential for operational safety. By ensuring a minimum number of personnel on hand, the operation can be conducted with a reduced risk of accidents, and communication can remain streamlined. Additionally, checking the brake systems is vital, as it confirms that the towing vehicle can safely control its motion during the towing process, preventing unwanted incidents.

This set of actions encapsulates the necessary precautions that should be taken before starting any tow operation, prioritizing safety and efficiency. In contrast to the other options, which may contain some relevant elements, they do not capture the same comprehensive approach focused on immediate operational safety and readiness.
