What reports must the VO prepare?

• A. A ventilation report signed by UMM about the mine ventilation system each month or if the ventilation system is change, a report detailing the system before and after the change, as soon as practicable after the change.
• B. A weekly safety report
• C. An annual environmental report
• D. A daily production report

Answer: (A)

Ventilation reporting is about keeping a clear, auditable record of how the mine’s ventilation is performing and what changes are made to it. The ventilation officer must produce a monthly ventilation report signed by the Underground Mine Manager, documenting the current status of the ventilation system—airflow, fan operation, damper settings, gas monitoring results, any faults, and actions taken. This monthly check helps ensure ongoing safety and compliance by capturing the system’s performance over time and providing management with a documented snapshot.

If the ventilation system is changed, the officer must prepare a report detailing the system before and after the change, as soon as practicable after the change. Recording the before-and-after details ensures any safety implications are understood, and there is a clear, traceable record of what changed and why.

The other options aren’t the required ventilation-specific reports for this role—weekly safety, annual environmental, or daily production reports serve different purposes and responsibilities.
