When can a Ventilation Officer hold another appointment?

• A. Only if the other appointment's functions do not prevent the VO from carrying out VO duties
• B. Any time
• C. Never
• D. Only if the other appointment is in a different mine

Answer: (B)

The key idea is that there’s no time-based restriction on how a Ventilation Officer can hold another appointment. The regulations don’t impose a blanket limit on when a VO may take on additional roles. The important requirement is that, if they take on another appointment, they must still be able to perform the VO duties effectively.

So, the question’s correct choice reflects that there isn’t a general time constraint dictating when a VO can hold another appointment. The other options imply specific timing or location limits that aren’t supported by the rule: there’s no absolute “never,” no blanket “only in a different mine,” and no automatic restriction tied to the other appointment’s function beyond ensuring VO duties aren’t compromised.
