What acronym is used to remember the steps for engaging the pump gear?

The acronym "Green, Green and 15" is used in the context of engaging the pump gear because it effectively embodies the sequence and actions required to properly engage the pump on a fire engine. The use of the color green often symbolizes that the pump is ready or that the operator can proceed safely. Additionally, the number 15 typically signifies a specific operational guideline related to pump pressures or RPMs, which are crucial for ensuring that the pump functions efficiently.

In this case, remembering the specific sequence (green indicating readiness, followed by the operational command involving the number 15) helps to streamline the process during potentially high-pressure situations, ensuring that driver engineers can quickly and accurately engage the pump when needed. This systematic approach is fundamental for maintaining operational safety and effectiveness in the field, reinforcing why this acronym is crucial for training and practical application in fire rescue operations.
