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.

Protecting Firefighters From Carcinogens
Suggestions for Initial Assessment, Sampling Strategies, and Risk Communication
Imagine getting a call from a fire district because they are concerned about firefighter exposure to carcinogens. Perhaps some of their colleagues were recently diagnosed with cancer, and there is a heightened sense of urgency to mitigate risk. Where do you start?

For OEHS professionals, identifying and mitigating workplace reproductive hazards is not only a regulatory responsibility but also a legal and ethical obligation.

Two OEHS fundamentals stand out when it comes to lead. The first is routes of exposure, or how someone gets lead into their system. The second is Paracelsus’s dictum, “The dose makes the poison.” With lead, there is no known “safe” level of exposure, making it a “true poison” for lack of a better term.
