H41 Interceptor with
DuPont Nomex® Nano Flex

The H41 Interceptor is the leading particulate blocking hood in breathability and comfort. This hood provides the greatest situational awareness while keeping you and your crew safe from potentially harmful carcinogens.

Certified to NFPA 1971.


H41 Interceptor particulate blocking hoods reduce firefighters exposure to persistent fire ground carcinogens and other harmful contaminants.

This 3-layer hood features an inner layer of DuPont™ Nomex® Nano Flex that's carried throughout the entire hood and sewn between 2 layers of 6.0oz PBI®/Lenzing (20%/80%).

Fluorescent Aerosol Screening Test (FAST)

The IAFF FAST test, performed on January 6, 2015, was completed to illustrate which areas of a firefighter's skin are most vulnerable to the exposure of submicron particles while in a typical house fire, some of which can contain carcinogenic properties and have long-term effects on firefighters' health.

The images to the right show the exposure points of a firefighter wearing standard turnouts after 30 minutes within an isolated chamber, filled with fluorescent aerosol "dust" and meant to emulate a fireground. A black light (UV) was used to illuminate the particles that penetrated the gear and found their way to the absorbent skin around the face and neck.


This test was one of the first indications that a culture change was needed in the fire manufacturing industry and carcinogen protection was a necessity to improve the future of first responder health and safety.

In response, Fire-Dex produced the H41 Interceptor® particulate blocking hood, which not only addresses the concerns of carcinogenic particles, but also minimizes heat retention, a common complication found in many particulate barrier hood on today's market.
