Measurement techniques result in generation of the key data required to enable the OHyP to calculate and correct levels measured into units comparable to the OEL standard units. The ability to perform these basic calculations is an absolute requirement for any Occupational Hygiene Practitioner from OH Technologist level. Check units!

Look for evidence of potential safety and health hazards: dust, grime in air or on surfaces. Other signs? Observe operations: cutting, heating, mixing, bagging. Observe controls: engineering, administrative, personal protective equipment. Make flow diagrams, notes, take photos if possible. List locations covered by the survey.

The course workbook will illustrate how to apply 150 equations to the real world of industrial hygiene and OH&S. Each section presents practical applications, short case studies, and sample calculations, both manually and using the IVE AutoCalc Spreadsheet programs.

Air monitoring is routinely conducted to evaluate employees’ full-shift time-weighted average exposures. Short-term or ceiling limit exposures may also be evaluated. See Interpretation of Results below. Air monitoring methods can include active and passive sampling techniques.
