NFPA 1975, Standard on Station/Work Uniforms for Fire and Emergency Services, specifies that garments shall be constructed from flame-resistant (FR) fabrics, like DuPont? Nomex?, or from nominally 100% cotton or wool fabrics. Fabrics made of Nomex? brand fiber are lightweight, breathable and extremely durable. The FR characteristics of Nomex? are built into the fibers and cannot be washed out or worn away. Garments made of Nomex? will also maintain their professional look without ironing.
Note: The head is uncovered in the test system and contributes to 7% of the predicted body burn.
Thermo-Man? tests demonstrate the higher level of flame protection that multilayer garments offer. Material selection and garment designs balance protection, mobility and heat stress.
Thermo-Man? system consists of a life-size manikin with 122 thermal sensors used to predict level, extent and location of potential burns of whole garments in simulated flame exposures. Thermo-Man? tests are performed in accordance with ASTM F 1930 guidelines.
