What's Happening?
Mesa Labs, a company specializing in calibration solutions, emphasizes the critical role of flow calibration in industrial hygiene and occupational and environmental health and safety (OEHS) applications. In an interview, Ram Parameshwar, Associate Manager
of Product Management at Mesa Labs, and Laurence R. Durio, Principal of Durio Consulting Services, discuss the evolution of calibration technologies and the importance of primary standards in ensuring accurate exposure data. They highlight that accurate flow calibration is essential for calculating airborne concentrations and ensuring the validity of sampling results. The discussion also covers the evolution from soap bubble meters to modern primary standards like piston provers, which offer greater accuracy and reliability.
Why It's Important?
Accurate flow calibration is crucial for industrial hygienists to ensure defensible exposure data. Without precise calibration, sampling results can be compromised, leading to false high or low readings that can result in unnecessary controls or jeopardize employee health. The use of primary standards, which are based on directly measurable physical quantities, is preferred for their accuracy and traceability. This ensures that occupational exposure limits are met and that the health and safety of workers are protected. The discussion underscores the importance of following regulatory and professional guidance to maintain data integrity.
