A respirator on the shelf doesn’t protect anyone.
Neither does a policy copied from another site.

In a recent article published by ISHN Magazine, OHD’s Senior Technology and Research Manager, Stephanie Lynch, PhD, CIH, CSP, outlines what it takes to develop a compliant, site-specific respiratory protection program.

From hazard assessment to fit testing protocols and training requirements, the article breaks down exactly what OSHA expects, and how to meet it. Think of it as your blueprint for building a program that works in the real world.

Volunteer firefighters serve on the front lines of danger, sometimes without the resources they need to fully protect themselves.

Respiratory hazards are among the most serious threats they face, but proper protection depends on one thing: a secure, verified respirator fit. Devices like the QuantiFit2 are critical for ensuring that protection, but for many volunteer departments, funding one can feel out of reach.

It doesn’t have to be.

In our latest blog, we break down realistic, proven funding options. From national grant programs and regional partnerships to community crowdfunding campaigns. Whether you lead a department or support one, you’ll find actionable steps to help bring this life-saving technology into your station.
Because firefighter safety shouldn’t depend on budget size.
