3oTrimestre10 | PROTECCIÓN LABORAL 64 Especial Fuego LUCHA CONTRA EL FUEGO | 3o Trimestre10 PBI Matrix: lighter and sturdier During the past edition of Interschutz, held in Leipzig, Europe came to know the new version of PBI fibres in black, mass dyed, as the most advanced way of using the leading fibre applied to the production of fabric for firefighting purposes. In addition to its excellent performance as a barrier against heat, it is highly resistant to crystallization and tears, which means clothing is more durable. As its shrinkage index is so low, clothes are also easy-care. All fabrics made with PBI-para aramid share these properties. The creation of the new PBI Matrix fibre means a step ahead, a new concept that improves on and exceedingly meets the requi- rements of current standards in force (EN-469.2005). The fabric looks different, with the Power Grid offering superior thermal protection, comfort, and rugged on-duty performance. This improvement means fabric weight has been reduced to 205 gr/m2, without impairing thermal resistance. Clothes are lighter, ergonomically designed, more comfortable, reducing metabolic stress. Thermal transmission in PBI is very much reduced, and that means clothes are cooler, a factor with a direct impact on reduced thermal stress. Various tests have shown the superiority of this material, though practice sessions in training schools, mainly those in container tests, have objec- tively shown the advantages of this fibre. The properties combine with resistance against chemicals, acids and alkalis, so clothing with PBI content is the preferred choice of American firefighters. Following the UK initiative of the ICP (Integrated Clothing Project), more and more firefighting bri- gades have chosen this material, with Scotland, Ireland and England taking the lead. Northern Europe countries like Swe- den, Finland, Denmark, and – more recently – Berlin, have also chosen to switch to PBI Matrix clothing, in the natural colour version. All over Europe, firefighter brigades are choosing PBI Matrix, including firefighters in airports, industry and military units. Different fibres for different applications For situations representing lesser risks, PBI TriGuard is the ans- wer. Lighter clothing offering superior protection, suitable for industrial clothing and resisting electric arc. Ideal for welders, forestry wardens, and or when fighting small fires, etc. For underwear, and mainly involving woven fabric clothing, the new PBI mixture with cellulose fibres offers the possibility of producing light fabrics with a great feel and excellent breat- hability. Antibacterial and odour-resistant PBI Base Guard is also the most suitable choice
