Protecting Our Greatest Asset: You.

All private U.S. employers are required to meet Federal Occupational Safety and Health Administration (OSHA) requirements for maintaining a healthy and safe workplace. Most states, including California and Oregon, have established their own agencies to clarify standards or exceed Federal guidelines for worker safety. While most firefighters are considered local or state government employees and are protected under autonomous rules, all independent firefighters and contractors fall under Federal OSHA jurisdiction*.

Emergency response workers are known for their unparalleled service to communities and businesses. Exposing themselves to environmental hazards that pose significant health risks is just a routine part of the job. In an age of unprecedented wildfires, legislators are now stepping up to protect every worker who could be impacted by smoke exposure. Breathing in fine particles released into the air during and after wildfires can reduce lung function and worsen asthma and other existing heart and lung conditions.


Rules and Regulations

The U.S. Environmental Protection Agency (EPA) is the Federal body responsible for establishing and monitoring environmental standards and conditions, and when it comes to air quality, OSHA takes its queue from them. Air pollution monitoring isn’t new, but our understanding of it and the tools we use to analyze it improve every day. The Clean Air Act (CAA) requires the EPA to set National Ambient Air Quality Standards (NAAQS) for six common air pollutants (also called Criteria Air Pollutants): Ground-level Ozone, Carbon Monoxide, Lead, Sulfur Dioxide, Nitrogen Dioxide, and Particulate Matter. Particulate Matter, or PM, is measured in micrograms per cubic meter (µg/m3).

In California, Title 8, Section 5141.1 outlines the responsibilities of California employers in protecting workers from wildfire smoke exposure. The law decrees that businesses must take action where the current Air Quality Index (AQI) is 151 or greater for airborne Particulate Matter 2.5 (PM 2.5). The AQI may be independently site-tested or determined using the EPA’s AirNow.gov web tool.

In Oregon, the legislative process is under way to enact protective regulations for workers exposed to excessive heat and wildfire smoke. On March 10, 2020, Governor Kate Brown issued Executive Order 20-04 (EO 20-04) that provides a directive to the Oregon Health Authority (OHA) and Oregon OSHA to jointly work towards creating two new safety standards§.

In Washington, Emergency Rule 2126CR103E was signed on July 16, 2021 and remains in effect until November 13, 2021. Adopted as WAC 296-62-085 Wildfire Smoke, the State’s workplace wildfire smoke standards are similar to those of California.
