Why Particulate Blocking Hoods Are Now a Fire Service Standard

Firefighting has never been safe—but the risks extend far beyond flames and heat. One of the deadliest hazards firefighters face today is invisible: toxic particulates. Studies show that firefighters are significantly more likely to develop cancer than the general population, largely due to repeated exposure to carcinogens found in smoke and soot.

To combat this threat, the National Fire Protection Association (NFPA) has taken a critical step. The newly updated NFPA 1970 standard, which consolidates multiple PPE standards, now mandates the use of particulate blocking hoods in structural firefighting ensembles. This isn’t just a guideline—it’s a shift in baseline protection requirements.

Why Particulate Blocking Hoods Matter

Traditional knit hoods were never designed to filter microscopic toxic particles. Smoke can penetrate through these porous materials, particularly around the neck, jawline, and ears—areas most vulnerable to long-term contamination. Particulate blocking hoods incorporate advanced filtration barriers to reduce exposure in these critical zones without compromising comfort or mobility.

LION’s RedZone Lineup: Trusted Protection, No Compromises

LION has stepped up with its RedZone™ line of particulate blocking hoods, designed to meet and exceed the NFPA 1970 standard. Here’s a breakdown of the current lineup:

RedZone™ PREVENT Hood

Lightweight, breathable, and designed to offer 360° particulate-blocking coverage.

Ergonomic design minimizes bunching and maximizes interface with other PPE.

Features a proven particulate-blocking layer that balances protection with comfort.

RedZone™ PREVENT CLEAR Hood

Offers the same protective features as the Prevent Hood, with an added bonus: no intentionally added per- and polyfluorinated substances.

A choice for departments prioritizing clean gear and reducing chemical exposure risks beyond particulates.

RedZone™ Nomex® Nano Flex Hood

Incorporates DuPont™ Nomex® Nano Flex, a cutting-edge barrier fabric that blocks particulates while remaining incredibly lightweight and breathable.

Also free of intentionally added per- and polyfluorinated substances, making it a top pick for health-conscious departments.

Excellent choice for high-heat environments where Nomex performance is trusted.

The Bottom LIne

The NFPA 1970 standard marks a turning point in firefighter protection—particulate blocking hoods are no longer optional. LION’s RedZone hoods give fire departments options that combine smart design, effective barrier tech, and an eye toward the future of clean PPE. Whether you're making your first move toward compliance or upgrading your current gear, choosing a high-quality particulate hood isn’t just regulation—it’s a commitment to long-term firefighter health.
