Which action should be taken when a gas detection alarm sounds?

• A. Vacate the structure immediately
• B. Continue to work after ventilating
• C. Notify supervisor but continue after review
• D. Ignore the alarm

Answer: (A)

When a gas detection alarm sounds, evacuate the structure immediately to fresh air. Gas can build up quickly in enclosed spaces and may be flammable or asphyxiating, so the safest action is to get people out right away rather than trying to locate the leak or continue work. Once you’re in a safe area, notify your supervisor and follow the site’s emergency procedures. Do not re-enter the building until authorized personnel declare it safe. Also avoid using electrical switches or appliances that could ignite fumes, and let trained responders handle ventilation and leak control.
