Nomex® III A

Protection Against Fire Hazards with Nomex® III A

At DuPont, we believe the standard for safety should always be a higher standard. So we engineered Nomex® III A to help give workers dependable protection against fire hazards.

Fires are unpredictable — situations can change in an instant with temperatures reaching 1900 degrees F, leaving workers vulnerable to serious injury. So for hazards like flash fire and pool fire, DuPont created Nomex® III A. A blend of 93% Nomex® with 5% Kevlar® and 2% antistatic fiber, this innovative fabric helps minimize break-open, and expands to form a stable and inert barrier between the fire and skin. This gives wearers the valuable seconds they need to escape from the hazard.

But comfort and fit are also an essential part of safety. In collaboration with manufacturers and mills, DuPont strives to help them make significant fabric improvements -- providing lighter weights, wicking finishes, and breathability.

At DuPont, innovation means testing beyond the basics with state-of-the-art technology like Thermo-Man®, one of the most advanced life-size thermal burn injury evaluation devices in the world today. The research and data DuPont scientists have collected have enabled them to improve upon the possibilities of Nomex® III A garments.

Additional Nomex® fabric considerations:

  • Widely used by petroleum, petrochemical, chemical, and utility industries, as well as firefighters
  • Inherent thermal protection that cannot be washed away
  • Durable and resistant to abrasion, tears, and chemicals
  • Meets the NFPA 1975 standard for firefighters’ stationwear
  • Meets the ASTM F1506 standard for workers’ apparel as protection from electric arc exposure
  • Complies with NFPA 70E Standard for Electrical Safety in the Workplace
  • Complies with NFPA 2112 Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire

DuPont Thermo-Man® helps advance thermal protection.

INFORMATION & IDEAS

  • Thermal Regulations Overview

    DuPont offers an overview of the typical regulation hazard codes and the leading thermal regulations impacting personal protective equipment (PPE).

  • NFPA 2113 Overview

    NFPA 2113 specifies the minimum selection, care, use, and maintenance requirements for flame-resistant garments for use by industrial personnel in areas at risk from flash fires or short-duration flame exposure that are compliant with NFPA 2112.

  • What Keeps You Safe?

    “What Keeps You Safe?” PPE videos from DuPont show how heroes in firefighting, military, law enforcement, and emergency response rely on DuPont invention and innovation.

  • Flame-Resistant Clothing for Laboratory Work

    When working in a laboratory environment where exposure to flame is a hazard, flame-resistant garments help to minimize potential burn injury during short-term and emergency exposure to flame in laboratory work.

  • NFPA 2112 Overview

    NFPA 2112, the standard on flame-resistant garments for protection of industrial personnel against flash fire, provides minimum requirements for the design, construction, evaluation, and certification of flame-resistant garments for use by industrial personnel.

  • Comfort & Heat Stress

    For maximum protection against fires, the body must be covered as completely as possible with flame-resistant protective clothing. This requires long pants and long sleeves, making for hot work in warm and humid climates. Understandably, industrial workers may be concerned about potential heat stress when wearing protective apparel. Learn more about the factors that can lead to heat stress, and how DuPont brands can help offer comfort and protection in protective garments.

  • Durability and Lifecycle of DuPont™ Nomex®

    Durable, inherently fire-resistant Nomex® fiber has an excellent wear life and helps contribute to bottom-line savings.

  • Flame-Resistant Technologies – FRT vs. Inherent

    What are the differences between “inherent” and “treated” flame resistant fabrics? Learn how each fabric reacts when exposed to heat, and when flame-resistant properties can be removed.

  • Who Wears Nomex® Racing Suits

    Racing professionals like Jeff Gordon, Robert Pressley, Gerhard Berger, and Jos Verstappen wear racing suits and gear made of Nomex® for a variety of reasons: it's lightweight, flexible, breathable, and comfortable. Most importantly, though, it's flame-resistant. And that performance benefit, more than any other, helped saved their lives. Read their testimonials.
