Fire and Smoke Testing

Cinnaminson, New Jersey, September 6, 2025

In May 2025, the U.S. Environmental Protection Agency published the “Best Practices Guide for Improving Indoor Air Quality in Commercial/Public Buildings During Wildland Fire Smoke Events,” a guide aimed at reducing indoor exposure to particulate matter and gaseous pollutants during wildland fire smoke events in public, commercial, and multi-unit residential buildings. This publication is for (1) individuals and groups with decision-making abilities for public, commercial, and multi-unit residential buildings including building owners and managers, school administrators, and facility managers; (2) federal, state, local, and Tribal environmental and public health organizations that provide information to communities to reduce exposure to wildland fire smoke in public or commercial spaces.
