What is the first sign that indicates the pump has engaged?

• A. The pump pressure gauge will rise
• B. The first green interlock light will illuminate
• C. An audible alarm will sound
• D. The engine speed will increase

Answer: (B)

The illumination of the first green interlock light is a critical indicator that the pump has successfully engaged. This light serves as a visual confirmation that the necessary safety protocols and mechanical systems are activated, allowing the operator to proceed with confidence, knowing the system is ready for operation. While other indicators such as the pump pressure gauge rising, an audible alarm sounding, or the engine speed increasing may occur subsequently, the interlock light is specifically designed to provide immediate feedback regarding the engagement status of the pump. It is essential for operators to recognize this signal as it helps ensure that all preceding conditions for safe pump operation have been met, thus enhancing safety and operational efficiency.
