How should miners respond to a gas detector alarm?

• A. Stop work, evacuate or move to fresh air as directed, and inform surface.
• B. Continue work and monitor readings.
• C. Silence the alarm and resume tasks.
• D. Notify only the supervisor and continue operations.

Answer: (A)

Gas detector alarms signal a potentially dangerous atmosphere. Stop work immediately, evacuate or move to fresh air as directed, and inform surface so the team can assess the situation and take action. This quick, coordinated response reduces the risk of ignition, toxic exposure, or oxygen deficiency. Continuing work, silencing the alarm, or only notifying a supervisor without involving surface personnel can leave you and others exposed to serious hazards.
