Nomex Fire Fighter Suit Navy Size M

Nomex Fire Fighter Suit Navy Size M (SOLAS / MED / EN 469:2020 Level 2)

The Nomex Fire Fighter Suit Navy Size M is a full-spec, structural marine and industrial bunker suit engineered to withstand direct convective flame exposure, high radiant flux, and superheated steam ingress. Designed to fully comply with SOLAS Chapter II-2 Reg 10 and the IMO Fire Safety Systems (FSS) Code, this garment utilizes an inherently flame-resistant (FR) 4-layer architecture.

Unlike chemical-treated cotton or modacrylic alternatives, genuine DuPont™ Nomex® does not degrade, melt, or drip when exposed to direct flame; instead, the fibers carbonize and swell to form a rigid thermal barrier between the exterior fire load and the operator. The jacket and trouser combination features articulated joints, heavy-duty aramid reinforcement pads on critical wear surfaces (knees and elbows), and full integration capabilities for Self-Contained Breathing Apparatus (SCBA) backplates and marine safety harnesses.

Features

1. Inherent Thermal Resistance: Formulated with 93% Nomex®, 5% Kevlar®, and 2% antistatic grid (P140), retaining structural cohesion and non-melt properties under temperatures exceeding 370°C (700°F).
2. EN 469:2020 Level 2 Rated Performance: Delivers top-tier protective ratings (X2 Thermal, Y2 Liquid Ingress, Z2 Breathability), shielding against convective heat, flashover radiant pulses, and pressurized fire main spray.
3. Breathable Microporous Moisture Barrier: Aramid needle substrate with an ePTFE vapor-permeable membrane prevents external salt water and chemical foam penetration while evacuating metabolic body heat and sweat.
4. Ergonomic Marine Articulation: Pre-curved arm sleeves, integrated underarm diamond gussets, and continuous crotch expansion panels ensure unrestricted ladder climbing, bulkhead penetration, and SCBA harness loading.
5. Fail-Safe Closures & Hardware: Heavy-duty quick-release brass/FR-polymer zippers with dual external Velcro storm flaps, thermo-stable Nomex wristlets, heavy-elastic suspenders, and 50 mm triple-trim retroreflective bands (Lime/Silver/Lime).

Frequently Asked Questions

Does this Nomex Fire Fighter Suit comply with current SOLAS and MED requirements for commercial ships?

Yes. This suit meets SOLAS 1974 (as amended), IMO FSS Code Chapter 3, and is certified under the Marine Equipment Directive (MED 2014/90/EU) carrying the Wheelmark identification. It complies with EN 469:2020 Level 2 standards required for enclosed space and structural marine firefighting.

How is the Nomex 4-layer construction superior to traditional treated cotton turnout gear?

Nomex is an inherently flame-resistant meta-aramid fiber. It does not rely on topical chemical fire retardants that wash out or degrade over time. Under extreme heat, the fiber thickens and carbonizes to block convective and radiant heat transfer. The multi-layer build incorporates a breathable ePTFE membrane that blocks high-pressure water and foam chemicals while exhausting body heat to prevent heat stress.

What is the service life of this marine firefighter suit in shipboard storage?

When stored in shipboard fire lockers in an unissued state away from high humidity and UV radiation, the Nomex turnout suit has an inspection-based service life of up to 10 years from the date of manufacture. Annual visual inspections and certification checks per MSC.1/Circ.1432 are mandatory.

Can this suit be worn for engine room emergency interventions involving hydrocarbon fuel leaks?

Yes. The outer shell provides antistatic dissipative performance to prevent incendiary static discharge in volatile atmosphere compartments. The PTFE moisture barrier offers short-term barrier resistance against heavy oils, diesel fuel splash, and synthetic firefighting foams. Any suit contaminated with fuel must be cleaned and decontaminated immediately.

What does the EN 469:2020 Level 2 (X2, Y2, Z2) rating mean?

Level 2 is the highest performance tier for structural firefighting gear. X2 indicates superior resistance to convective and radiant heat transfer; Y2 confirms maximum waterproof resistance against high-pressure water streams; and Z2 ensures high moisture vapor permeability (breathability), allowing sweat to escape and reducing internal heat build-up during intense damage control operations.
