. Or are BAFE suggesting that stainless steel extinguishers are breaching the Regs?
Unlikely as many of the member companies including some of the powerful multinationals that founded BAFE make a tidy sum selling stainless extinguishers.
BSEN3 is a manufacturing standard and nothing more. It is good practice to use equipment to this standard, but the whole point of the new regime is to allow flexibility - hence why for aesthetics or hygiene stainless steel extinguishers with appropriate signage are acceptable in certain cirumstances and also why for example, despite EN3 stating CO2 extinguishers must be of no less than 2 kilo, Chubb manufactured a 0.427 kilo CO2 extinguisher for the RNLI.
I agree the user painting them is not the most appropriate thing and they should have gone for purpose manufactured aesthetical extinguishers with signage if not red ones, but at the end of the day they are responsible - as long as the maintenance contractor makes the appropriate comments on service records and the assessor makes their objections, rationale and consequence of non compliance and both ensure the user's attention is drawn to these, then they should both be covered.
