When filling in at another station, when should personnel return to their station?

The correct answer is based on the expectation that personnel should ensure the readiness of the equipment they utilized while filling in at another station. When assisting another rig, it is standard procedure to reload the hose that may have been used during incidents they attended. This step is crucial for maintaining the operational capability of the rig and ensuring that it is ready for any future calls.

Returning the rig to service after completing these necessary tasks signifies that the equipment is fully operational and prevents any delays in response for future emergencies. This practice aligns with safety protocols and operational efficiency within the fire department, as it ensures resources are being managed effectively.

In contrast, simply returning when the other rig returns, waiting for a dispatcher call, or departing after the incident is mitigated does not prioritize the readiness of the equipment or the responsibilities of the personnel filling in at the station. Those actions could jeopardize the responsiveness of the station to subsequent emergencies.
