How long is a temporary absence for a Ventilation Officer?

• A. For up to 14 days with no conditions.
• B. The UMM may assume the duties of the VO during the absence if the absence is for not longer than 7 days and the manager holds a ventilation officer's certificate of competency.
• C. For up to 30 days with permit.
• D. The VO cannot be replaced during absence.

Answer: (B)

The situation allows for a short-term handover of duties to keep essential ventilation oversight continuous. The rule is that the underground manager may assume the ventilation officer’s duties if the absence is no longer than seven days and the manager holds a ventilation officer’s certificate of competency. This combination ensures someone who is qualified takes over for a brief period, maintaining safe and compliant ventilation management without leaving critical responsibilities unfilled. If the absence lasts beyond seven days, a different arrangement is needed—typically appointing someone with the appropriate VO qualifications or obtaining the necessary regulatory approval. The other options inaccurately state longer timeframes or deny replacement, which would not align with safety and regulatory expectations.
