Welcome to our in depth blog series: How Many Samples to Collect? Sample Till You’re Sure.
Gus Manning, Chief Technical Officer & company founder, has made his life’s work to bring accurate, cost effective, and easy to use samplers to the workplace, and make work environments safer for workers. The OSHA enforcement strategy – assuming workplace exposures could be well characterized by a small number of samples – has been found deficient in a number of classic studies, cited in this series.
Gus’s work for this series is grounded in the AIHA’s Exposure Assessment Committee’s finding that IH practitioners may underestimate exposures when reviewing workplace exposures, because workplace exposures tend to have high variations that follow a skewed (lognormal) pattern, rather than a normal (Gaussian) pattern.
Part 1 of this series expands the concepts of the AIHA training course, Making Accurate Exposure Risk Decisions. You will learn about Exposure Risk Questions & OEL’s, Worker Exposure Categories, and how to use the IH Data Analyst Tool.
