The Science Behind Personal Protective Equipment for Firefighters


The mini-documentary, “When Seconds Make All the Difference,” shows how DuPont and LION, a global leader in protective gear for first responders, have collaborated to bring protection to a new level for firefighters and first responders using advanced blends of DuPont™ Kevlar® filament and DuPont™ Nomex.

DuPont and LION collaborate with fire departments around the world to test new fiber technologies and thermal protection within firefighter gear. DuPont™ Nomex® can withstand temperatures up to 700 degrees Fahrenheit (370 degrees Celsius). Skin can burn instantly at temperatures of 131 degrees F (55 degrees C). Nomex® and Kevlar® are inherently fire-resistant and do not need to be treated. Tested through DuPont’s rigorous Thermo-Man® unit, they are both self-extinguishing and durable. DuPont is constantly innovating to develop and produce “smart fiber” materials that can detect high temperatures and react accordingly for greater thermal insulation.
