Integrated RFID for boot identification, PPE inspection records and service life tracking — ideal for large brigade fleet management.
Yes. The Voelkl ONE carries full DIN EN 15090:2012 F2A structural firefighting certification including WR (water resistance), HRO (heat-resistant outsole), HI3 (sole heat insulation at 150°C), CI (cold insulation), AN (ankle protection) and SRC (slip resistance). It is designed and tested for the demands of interior structural firefighting.
The quick-entry lacing system includes an emergency opener — a mechanism that allows the lacing to be released rapidly in one action when it is not possible to unlace conventionally. This is a critical safety feature for self-rescue or casualty dressing in time-critical rescue environments.
The Voelkl ONE (Ref 33331) has a taller 29 cm shaft (Form D) and weighs approximately 1,370 g — providing more leg coverage for interior attack operations. The Primus 22 (Ref 33322) has a shorter 23 cm shaft at approximately 1,150 g. Both carry the same full EN 15090 F2A rating and Sympatex® membrane lining.
Yes. All Voelkl boots supplied by Fire and Rescue Tech include the EU Declaration of Conformity and EN 15090:2012 test certificate required for PPE procurement compliance under EU PPE Regulation 2016/425 — accepted by civil defence procurement authorities across Egypt, UAE and GCC countries.
