Calibration and Specialty Gas Safety: Top Dos and Don’ts to Remember

The global specialty gases market is forecast to surpass $14 billion by 2026. And as the industry continues to grow, knowing how to stay safe during specialty and calibration gas use is essential. Here are just a few dos and don’ts to keep in mind when considering the best safety practices of working with specialty and calibration gases.


DO: Know OSHA’s best practices


First, you should know that OSHA has laid out a number of best practices regarding calibration gas testing. For example, a bump test, which is also known as a functional test, should be performed every day before using a direct reading portable gas monitor. Additionally, a full calibration should be carried out on any instrument that fails the functional test. ISEA recommends more frequent gas calibration testing if environmental conditions that could affect instrument performance are suspected, such as sensor poisons. Overall, ISEA allows for less frequent calibration verification under certain conditions, but the interval between testing should never exceed 30 days


DON’T: Neglect regulator accuracy


It’s also important to keep an eye on regulator accuracy. Be sure to use the correct regulator and fittings in order to supply gas to an instrument. Incorrect flow can cause the reading to be off.


DO: Get a second opinion if needed


If you have any concerns whatsoever about the accuracy of a reading, how often you should be calibrating a device, or any other information regarding calibration or specialty gases, don’t hesitate to reach out to a professional, like a supplier, who can take a look at your application needs and make recommendations regarding best practices.


DON’T: Zero the device in contaminated air


Finally, be sure to always zero the device in fresh air to ensure a proper reading. For example, an office environment is typically considered to have clean air and can be used for zeroing a device.


A report done by Grand View Research predicts that cost reduction, yield improvement and performance optimization are projected to drive the global the specialty gas market over a six-year timespan (2014 to 2020). With that in mind, it helps to understand the best accuracy and safety practices of various specialty gas applications. For more information about specialty gas equipment, contact Mesa Gas.
