Sudden cardiac death has consistently accounted for the largest share of on-duty firefighter deaths since the NFPA began this study in 1977. 1

Key Factors of Heat Stress:

  1. Weight
  2. Flexibility
  3. Thickness

As an industry, we have been trained to think that you have to sacrifice thermal protective performance (TPP) in order to achieve maximum total heat loss (THL).



Introducing TECGEN71

We offer the most lightweight, thin, and flexible fabric composites with the highest THL ever seen in the fire service...without sacrificing thermal protection or durability. Introducing TECGEN71, an exclusive outer shell available in Fire-Dex FXR turnout gear.

History of TECGEN71:
In September of 2015, Fire-Dex acquired TECGEN® PPE and began selling the PPE line within the Fire-Dex Dealer Network. After analyzing the lightweight TECGEN® fibers, our product development team began creating a stronger, lighter weight system by merging it with tried and true Nomex®/Kevlar® layers from DuPont. The product tests and wear trials have yielded measurable differences from traditional turnout gear available in the market today.

To evolve and develop the fiber and offer some of the most protective gear available today, Fire-Dex partnered with Milliken & Company, headquartered in Spartanburg, South Carolina. Milliken shares a long history of fabric innovation and design.

What is TPP and THL?

From the U.S. Department of Homeland Security and FEMA, thermal protective performance (TPP) “measures how well a fabric protects the wearer against second-degree burns in a flash fire. The higher the TPP value, the more thermal protection the fabric provides relative to other fabrics.”

Total Heat Loss (THL) measures breathability, or the ability of the total composite system to allow heat and moisture to evaporate. Breathability is a key factor in reducing heat stress.

Most turnout gear options focus on TPP or reducing the weight as it is difficult to attain both measurements. TECGEN71 is different. The lighter weight total composite system allows more breathability and flexibility, yielding a 48% higher THL without sacrificing TPP or durability.

Fabric to Change Your Mind

TECGEN71 Fabric

TECGEN71 features rip twill construction that puts the proven strength of 60/40 Kevlar®/Nomex® on the face of the fabric, while creating a super structure of the TECGEN® fiber inside.
