Industrial workplaces in all sectors are familiar with industrial hygiene sampling. Done by a consultant or in-house, it proceeds in a similar manner: a scope is created, sampling equipment/media is secured, and monitoring occurs over one or more shifts. The results are received from the laboratory and are below the exposure limits. Is all well? Sometimes the reason the results were good is that the wrong chemicals were assessed. This is not the fault of those in charge of monitoring...SDSs can omit critical information, unknown reaction products can be created, or processes unknowingly changed. In my 20+ years of industrial hygiene sampling I've encountered many surprises that initially seemed absurd, but in hindsight made perfect sense. My hope is to present case studies that show such results so that safety professionals can apply the knowledge to their own companies.
