Course Description:
Recorded at AIHce EXP 2023
Although there are recent guidelines from AIHA on the sampling and analysis of wildfire residues, there are no other published microscopical analysis methods specific to wildfires or structure fires. In attempts to fill this void, laboratories have taken different approaches ranging from adopting or simply ignoring critical information provided in the AIHA "Technical Guide for Wildfire Impact Assessments for the Occupational and Environmental Health and Safety Professional". Instead, some laboratories are relying on methods published for other analytes such as the 2018 ASTM Method 6602-13 for Carbon Black, or the 1993 USEPA "Test Method for the Determination of Asbestos in Bulk Materials". The goal of this presentation is to help clarify the most effective combinations of sampling and microscopy analysis methods to get reliable and comparable results in the measurement of settled wildfire and structure fire particles.
Learning Outcomes:
Upon completion of the session, the participant will be able to:
• Recognize how the limitations of sampling and microscopy methods can impact the results.
• Compare commonly used sampling procedures and preparation methods.
• Illustrate how the sampling and microscopical analysis method combinations affect reliability.
• Analyze how the procedures impact the microscopists' ability to accurately quantify the residual combustion particles and depositional patterns.
