Dirty Nomex®

 

Nomex® is the brand name for a heat and flame-resistant textile made by the DuPont chemical company and first marketed in 1967. Today, more than three million firefighters and aviation personnel around the world are protected by structure fire turnout gear, wildland fire personal protective equipment (PPE), and flight suits and jackets made of Nomex®.

Nomex® is not flame-proof. It burns when you hold a flame to it, but stops burning once the heat source is removed. The thick woven structure of synthetic fibers is a very poor conductor of heat. When exposed to heat, the fibers expand, closing the spaces between them insulating the wearer. But to work correctly, Nomex® needs proper care.

Dirty Nomex®

  • Wash Nomex® like normal laundry, but always include a rinse cycle that adequately removes soaps and detergents.
  • Nomex® garments should never be subjected to strong oxidizing agents such as peroxides or bleaches. These products harm the physical strength of the fabric.
  • Tumble dry and remove while slightly damp. Over-drying damages the fabric.

Poison Oak/Ivy/Sumac on Nomex®

National Technology and Development Program (NTDP) conducted research on laundering Nomex® firefighting clothing that has been contaminated with urushiol oil (what causes the rash) from poison oak/ivy/sumac exposure.

  • NTDP recommends that fire clothing contaminated with urushiol oil be cleaned following normal Nomex® laundering procedures, with a degreaser such as a detergent or a laundry soap, and as soon as possible.
  • Extra care should be exercised when handling the contaminated clothing, and it should be kept separate from unaffected clothing and equipment.
  • Put the affected clothing in a marked bag if you are giving it to someone else to wash. Before handling the affected clothing, apply a skin-barrier product such as Ivy Block or Technu®.

Fuel-Soaked Nomex®

Flammable contaminants will reduce the thermal performance of any flame-resistant garment including Nomex®.

  • Proper and periodic cleaning is essential to maintain thermal protective performance.

 

Action Item -

Nomex® is not effective if it is excessively dirty, fuel-soaked, or has holes. Does your Nomex® need to be washed, repaired, or replaced?

NWCG Standards for Rapid Extraction Module Support, PMS 552

Date: July 10, 2024
Contact: Incident Medical Unit Subcommittee 

A new publication from the Incident Medical Unit Subcommittee is now available. The NWCG Standards for Rapid Extraction Module Support, PMS 552 will be used as a guide and as an opportunity to begin to build out Rapid Extraction Module Support (REMS) modules for the remainder of Fire Year 2024. These standards will be fully implemented as the minimum standard starting in January 2025.

NWCG Standards for Rapid Extraction Module Support outlines the roles, duties, qualifications, and equipment pertinent to REMS. A REMS team, strategically stationed at wildland fires, plays a pivotal role in prioritizing swift access and medical treatment to injured or ill firefighters for safe and efficient egress off the fireline. This ensures their rapid transport to definitive medical care in cases of emergency during firefighting operations, highlighting the invaluable contribution of the REMS team to firefighter safety and well-being.

National Wildland Firefighter Day

Date: July 2, 2024
Contact: National Interagency Fire Center 

The National Wildfire Coordinating Group (NWCG) would like to recognize July 2, 2024, as National Wildland Firefighter Day (NWFFD). Established in 2022, NWFFD honors the dedication of wildland firefighters and support personnel. This day falls within the 2024 Week of Remembrance (June 30 - July 6), providing an opportunity to renew our commitment to wildland firefighter safety while remembering those who have fallen in the line of duty.

NWCG continues to provide leadership to enable interoperable wildland fire operations among federal, state, local, Tribal, and territorial partners. NWCG standards and training establish common practices to contribute to safe, effective, and coordinated national interagency wildland fire operations.
