In the event of a gas monitor alarm with no immediate evacuation possible, what should you do?

• A. Ignore the alarm and continue working.
• B. Wait for someone to tell you what to do.
• C. Immediately start blasting to ventilate.
• D. Follow the emergency plan, seek fresh air, and move to the safest designated area or refuge if safe.

Answer: (D)

Gas alarms warn of dangerous atmospheres, so the action taken must be immediate and aligned with the mine’s emergency plan. The best course is to follow that plan, get to fresh air, and move to the safest designated area or refuge if it can be done safely. This approach minimizes exposure by directing you toward cleaner air and a controlled safe zone where further instructions and communication can occur. It also provides a clear, organized response rather than leaving you to decide on the spot.

Ignoring the alarm ignores the safety system and can lead to rapid and unnecessary exposure. Waiting for someone to tell you what to do delays protective action and increases risk. Trying to ventilate by blasting without a coordinated plan is not reliable or safe and can spread gas or create ignition risks. Following the emergency plan and relocating to fresh air or a refuge ensures you’re using established safeguards and communication channels designed for these scenarios.
