Potential problems with Hy Flex fire extinguishers

One of our members has informed us that the suppliers of HyFlex fire extinguishers have advised them that there is a potential problem with their DDC fire extinguishers. Following a study of the units, it has been discovered that the M3 grub screw set into the handle, which acts as the main valve, is missing from some of the units.

While operating a faulty unit, only the handle acts on the pin, and consequently causes malfunction of the unit. Therefore all units need to be checked to ensure that the relevant screw is in place.

Should the screw be missing, then the extinguisher should either be removed from service until a replacement screw is available or a competent person should fit a compatible M3 screw to the handle and adjust accordingly.
