The emplacement cannot be completed until the TFOM reaches what value?

• A. 1 or less
• B. 2 or less
• C. 3 or less
• D. 4 or less

Answer: (C)

Emplacement is governed by a readiness threshold: the operation can proceed only when the TFOM is at or below a specific limit. In this context, TFOM must reach 3 or less before emplacement can be completed. Lower TFOM values indicate conditions that meet the safety and performance criteria for finalizing emplacement, so once TFOM is 3 or below, the required standards are satisfied. If TFOM stays above 3, the emplacement criteria aren’t met and you must wait or adjust conditions before proceeding. The other options imply thresholds that are either stricter (1 or less, 2 or less) or looser (4 or less) than the standard gating, which is not how the readiness criterion is defined here.
