For process manufacturers and producers with hazardous locations, gas detection systems are a key element in safe operations.In this short 2:27 YouTube video, 5 things you should know about Gas Detection, Emerson’s Edward Naranjo shares tips about the installation, commissioning and ongoing maintenance of your gas detection equipment.
He opens with the first tip, to make sure you have adequate detection coverage so that no assets are going unmonitored. This analysis is usually done on the initial design of the site. Changes made in the placement of equipment or the addition of walls can cause the need to relocate the gas detectors.
For detection of heavier gases, such as hydrogen sulfide, the detectors should be located near ground level. Be aware of other conditions such as snow drifts or standing water that can impact the placement of the detectors.
Edward’s second tip is to make sure there is proper airflow to the detector. If the area where the detector is located is stagnant, then it may not timely warning.
His third tip is to calibrate the sensor upon initial installation and subsequently at one-year intervals. For tip #4, Edward counsels that for routine maintenance, the sensors should be bump-tested regularly. The level of bump should be in the accuracy range you’re expecting from the detector. Quarterly tests are the standard recommendation, but make sure to check your operating manual for specific gases.
Edward’s final tip was to make use of the HART diagnostics available with many gas detectors, such as the Millennium II gas detection transmitters. The diagnostics will provide early warning when the sensor is getting to the end of life to allow scheduled maintenance.
Edward pointed to the flame and gas detection page where you can get more information on these flame and gas detection transmitters and sensors.
