Dry powder fire extinguishers The transitional period for the introduction of the new fire extinguisher regulations detailed in Section (K)-Appendix 3, has presented an anomaly regarding the use of dry powder hand-held fire extinguishers. The existing regulations in (K)3 state simply that dry powder extinguishers are prohibited. However, the new Appendix 3 regulations detail dry powder as a permitted extinguishant for a hand-held system.
These new regulations, although not mandatory until 2019 for new build vehicles and 2022 for all other vehicles, can be applied now if a competitor wishes to in advance of the mandatory implementation. Therefore – providing it meets the minimum quantity of extinguishant detailed in Section (K) Appendix 3 – a dry powder hand-held fire extinguisher can now be used.
Please note under the new regs the minimum size of handheld AFFF extinguishers will be increased from 1.75 Ltrs to 2.4 Ltrs Existing vehicles competing prior to 1st January 2019 will be ok until 1st January 2022. New build vehicles will have to comply from 1st January 2019
