Particulate Protection in Firefighting Hoods: Procovès Nomex® Nano Flex

Firefighters rely on protective hoods as crucial components of their gear, but traditional designs have notable shortcomings in shielding against harmful particulates. Studies have revealed alarming rates of cancer among firefighters, attributed in part to exposure to carcinogen-laden soot and particles, particularly in vulnerable areas like the head, face, and neck.

While standard hoods offer thermal and flame resistance, they often lack adequate protection against these toxic particles. Recognizing this gap, the industry has responded with innovative solutions aimed at enhancing both thermal insulation and particulate filtration.

One such solution is the Nomex Nanoflex Structural Fire Fighting Hood from Procoves. Incorporating Nomex patented NanoFlex LAM Technology, this hood provides excellent thermal insulation and low thermal conductivity, ensuring complete protection from particulates, especially in wildland firefighting activities.

Constructed from knitted fabric comprising 98% aramid and 2% antistatic materials, the Nomex Nanoflex hood features Nomex NanoFlex 335 LAM filters and Nomex Rouge sutures. Its design ensures complete coverage of exposed areas during firefighting operations, with a breathable mesh parietal section for added comfort.

Key product details include:

  • High filtration efficiency (99%)
  • 100% recyclable raw materials, compliant with REACH OEKO-TEX standards
  • High degree of breathability and comfort, with air permeability of 60/80 litres per minute compared to standard membrane hoods (5/6 litres per minute)
  • Stretch and comfort properties, with elongation and recovery rates of over 75% and 90%, respectively
  • High absorption and evaporation rates for effective moisture management
  • Very low Water Vapor Resistance (RET) value
  • Minimal rubbing and crackling noise during use
  • Tested durability, with no reduction in protection and performance even after 50 washes, and no signs of damage after 100 washes
  • Backed by a 2-year warranty for materials and workmanship.

Incorporating advanced technology and materials, the Nanoflex Structural Fire Fighting Hood offers firefighters unparalleled protection against particulate matter, ensuring their safety and well-being in the line of duty.

What Is An Arc Flash?

An arc flash is a sudden release of electrical energy that occurs when current jumps across a gap between two conductors or from a conductor to a ground. The arc flash generates an intense burst of heat and light that can cause serious injuries, damage to equipment, and fires.

Arc flashes can occur in a wide range of electrical systems and equipment, including switchgear, transformers, motors, and other high-voltage components. They can be caused by a variety of factors, including equipment failure, human error, or a short circuit.

The intense heat generated by an arc flash can cause severe burns, as well as ignite clothing and other materials in the surrounding area, leading to secondary fires. The bright light from the arc flash can also cause temporary or permanent vision damage.

To prevent arc flash incidents, it’s important to follow proper electrical safety procedures, including wearing appropriate personal protective equipment (PPE), de-energizing equipment before working on it, and maintaining a safe distance from energized equipment.

Understanding Arc Ratings and Calories

Now that you understand FR clothing is tested and given an arc rating, you know that the arc rating measures the amount of heat the flame resistant fabric blocks when exposed to electric arc. The arc rating is the number of calories that the garment is expected to “absorb” if exposed to an electric arc. Arc rating is, in essence, the level of protection provided to you, the wearer.

Calorie is the unit of measure of the heat energy of an arc flash and the protective level of FR clothing. The bigger the calorie number, the greater the heat energy level of arc flash and the greater the protective level of the clothing. You will be protected from an electric arc if your clothing has a higher calorie arc rating than the calories of heat generated by the arc.

While it does not matter if the fabric has an Ebt,  ATPV and or ELIM value, it is important to pay attention to the calorie level the fabric can support* (as expressed in cal/cm2)
