When a gas detector malfunctions, it’s important to first remove it from service to prevent false readings. Contact your device manufacturer or authorized service center for guidance as every model is unique. Often, recalibration can resolve issues. If not, the unit might need repair or replacement.
Always have backup detectors available and ensure all personnel are aware of the situation.
Safety should never be compromised, so don’t hesitate to halt operations if necessary until the issue is resolved.
Your proactive approach is commendable in ensuring a safe work environment.
