What is a critical step prior to pump operation?

Conducting a thorough equipment check is essential prior to pump operation. This step ensures that all components of the fire apparatus are functioning correctly and are in a state of readiness. An equipment check typically involves inspecting the pump, hoses, valves, gauges, and any other necessary firefighting tools to confirm that they are all operational and safe to use. Not only does this step help prevent mechanical failures during an emergency, but it also promotes safety for the personnel involved.

The other options, while important in their own contexts, do not address the fundamental necessity of verifying that the equipment itself is ready for immediate and effective use in a potentially high-stress situation. Neatly coiling hoses, filling the tank, and practicing operations can all contribute to effective use of the equipment, but they do not replace the critical need for an initial comprehensive inspection to ensure readiness.
