As a safety officer, your question is absolutely crucial. Gas detectors are indeed lifesaving tools that need to be in their best form at all times. Typically, the lifespan of gas detectors can vary depending on the brand and usage, but a good rule of thumb is to consider replacing them every 2 to 3 years.
However, regular maintenance and calibration are equally important. Most manufacturers recommend a monthly or at least a yearly calibration to ensure the detectors are functioning correctly.
Remember, if a detector shows signs of malfunctioning or if it’s past its typical lifespan, it’s better to replace it immediately rather than risk a potential safety hazard.
I hope this helps, John. Keep prioritizing safety!
