Before performing a PAC-Fire, which PSOT is typically run?

• A. PSOT 14
• B. PSOT 22
• C. PSOT 12
• D. PSOT 9

Answer: (A)

The essential idea is that a pre-fire readiness check is performed to confirm all safety and readiness conditions are in place before firing. In the standard PAC-Fire procedure, the PSOT that is typically run right before firing is PSOT 14. This particular PSOT is designated to verify the critical readiness items needed to proceed, such as safety interlocks, control states, and required approvals, ensuring the system is in the correct, safe state to initiate firing.

The other PSOT numbers correspond to checks for different stages or subsystems, so they aren’t the standard pre-fire check that’s performed immediately prior to PAC-Fire.
