Calibrating Gas Detector – All You Need to Know

Do you know a poorly performing gas detector can risk your workers and property? Yes! Having an accurate gas detector is crucial when working in confined spaces or with gases where the atmosphere is filled with harmful gases. Without proper functioning gas detectors, workers are at risk of illness due to exposure to harmful gases, chemical fumes, and injury when an explosion occurs. While gas detectors can help prevent gas inhalation and fires, the detector must be calibrated using calibration gas periodically to ensure it does its job properly and provide accurate readings.

In fact, calibration gases is the key to the reliability of gas detection sensors. But, what are they? How often should you calibrate the gas detectors? In this article, let's look at calibration gases to get answers to all your queries.

What Is Calibration Gas?

Calibration gases are used to calibrate the gas detectors and sensors to ensure their reliability and accuracy. Testing the sensor by calibrating it with a known concentration of gas, calibration gas, is the only way to ensure that a gas detector is accurate and functioning properly.

How Often Should You Calibrate The Gas Detector?

-While there are no rules as to when you should calibrate the device, OSHA advice some best practices to be followed, including:

-A bump test or full calibration must be performed every day before using a Personal gas monitor.

-A bump test should be done when any instrument/device fails the functional test.

-Perform full calibration at least every month.

The gas monitors should be calibrated more often if environmental conditions could affect the device's performance. For example, if high gas concentrations, extreme temperature, mechanical shock, sensor poisons, etc., are suspected to be present.

It's advisable to follow these guidelines. However, if doubtful, please perform a full calibration. When the detector is exposed to a known concentration calibration gas, it's possible to confirm the reading accuracy and the functioning of the alarm.

What Can Happen If You Don't Calibrate The Gas Detectors?

Please be aware that employers that fail to perform the bump test regularly and document the device's performance are susceptible to fines for not complying and preventable workplace accidents that lead to injuries and death in the worst case.

Frequent calibration is not only safe but also mandatory in most industries. Before conducting the test, ensure you've the right tools at your disposal and perform it in a ventilated space for more accuracy. When working with Infrared Gas Detectors, personal gas monitors, etc., calibration is the key as it can prevent accidents and save lives and property damages. If you're uncertain about the calibration process, please seek the assistance of the instrument's supplier.
