How common is it now for refillable powder and foam extinguishers to actually be recharged after use (either on a fire or discharge tested)?
I get the impression that, increasingly, powder extinguishers are simply replaced and scrapped after five years, rather than refurbishing and refilling, because there is now little difference in cost. New environmental legislation on foam extinguishers means that test discharging on site is difficult, so are these now simply being scrapped after five years as well?
Of course, having a new extinguisher might be the best way to ensure that it will work properly, but it does seem a waste to simply replace perfectly serviceable extinguishers after just five years.
I wonder if there is a similar issue on mainland Europe. Does the greater popularity of cartridge operated extinguishers in countries like France and Germany make it easier to refill on site?
