Which work packet covers the power-down of the launching station?

• A. WP 0010
• B. WP 0012
• C. WP 0011
• D. WP 0013

Answer: (B)

The task tests understanding of how maintenance procedures are organized into dedicated work packets, with each packet covering a specific action. The packet that covers powering down the launching station is the one designed to safely de-energize and secure the launcher. It provides the step-by-step sequence to shut off electrical power, isolate the power sources, engage safety interlocks or lockouts, verify that all energy has been removed, and record the shutdown. This focus on safe de-energizing and securing the system ensures the launcher cannot re-energize unexpectedly and that maintenance personnel can work in a controlled, safe environment. Other packets are built for different actions—such as powering up, performing setup or diagnostics, or conducting maintenance checks—so they address those tasks rather than the shutdown sequence.
