DuPont™ Nomex®; Proven heat stress protection for firefighters

Published:  28 May, 2013

DuPont is the inventor and the world’s largest producer of high-performance materials and solutions with leading world brands such as DuPont™ Nomex®, Kevlar®, Teflon® and Tyvek®, providing personal protection, be it thermal, mechanical or chemical, to over 90 countries.

Unlike other materials available to firefighters and emergency service personnel, protective clothing made using Nomex® fibres is inherently flame-resistant and won’t melt, drip or support combustion in the air. The high air permeability of Nomex® allows body heat out of the garment, thus reducing heat stress – the number one cause of casualties among firefighters.


DuPont™ Nomex® fibres are renowned for their flame and heat protection properties and are used in turnout gear for more than three million firefighters around the world. Any garment that incorporates DuPont fibre is put through rigorous testing using the DuPont™ Thermo-Man® manikin to reveal how the garment would perform under a real life flashover fire. It is the only mobile test manikin available for testing and measuring the protective performance of a variety of garments and is the benchmark for all fire protective garments.

For firefighters intervening in a host of situations like flood and water rescues, car accidents and paramedical tasks, garments of Nomex® fibre helps provide needed protection and are comfortable to wear – not just when fighting fires, but on a day-to-day basis too. DuPont technical experts and scientists are constantly developing new methods and technology to improve firefighter safety, looking specifically at protection from heat and flame, durability, reducing the risk of heat stress and providing extra seconds of safety when it counts.

Fire and rescue services across the UK use fabrics made with the DuPont fibre to protect their firefighters, including London Fire Brigade and Nottinghamshire Fire and Rescue Service. Most recently, after careful research and a rigorous testing period, West Midlands Fire Service chose to use Hainsworth® TITAN fabric that incorporates DuPontTM Nomex® and DuPontTM Kevlar® fibres in their turnout gear to protect their 2,000 men and women firefighters across the county’s 39 community fire stations.

DuPont also runs the DuPont™ Nomex® Partner Programme, a carefully-selected network of customer-oriented and progressive weavers and garment manufacturers whose fabrics and garments pass the rigorous quality controls of DuPont. DuPont, together with its Nomex® Partners, work o continuously improve the protective performance of firefighter garments.
