If a methane monitor alarms or indicates dangerous levels, what should you do?

• A. Turn off the alarm and continue working.
• B. Ignore and wait for someone else to react.
• C. Only check the readings later.
• D. Stop work, move to a safe location, and report to the supervisor; await instructions.

Answer: (A)

When a methane monitor alarms, treat it as an immediate hazard and take protective action right away. The priority is to stop work, move to a safe location with good ventilation and away from ignition sources, and report the situation to your supervisor or the designated safety contact, then wait for instructions before resuming work. This is essential because methane in the air can reach explosive or dangerous levels quickly, and the alarm is there to give you time to evacuate and be accounted for. Ignoring the alarm, continuing to work, or delaying action compromises your safety and others around you, and simply checking readings later could miss dangerous changes in the atmosphere. Following the alarm protocol ensures you’re in a monitored area and that the right steps—communication, assessment, and clearance—are taken before resuming activities.
