Sampling and Analysis FAQ
Cultivating a Partnership Between Practitioners and Laboratories
Industrial hygiene professionals come from a wide variety of educational backgrounds, with many having stumbled into this profession. It’s expected that their understanding of sampling and analytical methods ranges from novice to expert. This FAQ addresses topics of frequent discussion between labs and IHs.
Measuring Asbestos Exposure
ASTM Revises Method for Asbestos by Phase Contrast Microscopy
Although no asbestos is mined in the United States and very little is imported these days, it is still encountered occupationally. The recent revision of ASTM D7201 incorporates modern developments in research on the sampling and analysis of asbestos in air.
Ventilation in Unoccupied Labs
Engineering and Safety Considerations
Many laboratories draw more ventilation when they are in active use than in the unoccupied state, when the workers are not present. In building management terms, reduced airflow to an unoccupied room is called ventilation setback. It's a very effective tool for energy conservation in labs and is now appearing in energy codes and standards for laboratory buildings.

Monitoring Approaches During the Jasper Wildfire Mass Demolition Recovery
The July 2024 Jasper Wildfire Complex was one of the most expensive natural disasters in Canada's history. Following the fire, the dust-generating nature of the cleanup and the proximity of residents and the visiting public made this a complex, highly sensitive project. Enter the industrial hygienist to conduct a risk assessment for the removal work.
From the Laboratory to the Field
Implementing a Logic for Developing Dermal and Surface Methods
Few validated methods for sampling and analysis of surfaces and skin exist, and they are difficult, time consuming, and costly to develop and evaluate. This article takes a closer look at the challenges of interpreting available methods and the key variables that determine their suitability for real-world deployment, including field validation.
