Extinguisher media fitted to a consumer unit.
« on: May 12, 2021, 12:58:12 PM »
Hi,

Just seen a YouTube video regarding an extinguisher fitted to a consumer unit and a test fire being created within the devise. The video does not explain how the unit works or what the extinguishing media is. Have a look - I would be interested in peoples comments. It is is CO2 then this may remove the flames in the first instance but retained heat could lead to re-ignition. I could no see any foam or water coming out following it going off (water on electrics????). Apart from the occasional Wylex, Crabtree or Volex board with dodgy MCBs just how common are consumer unit fires?  https://www.youtube.com/watch?v=gXcE63iyxtY

Looks similar to Fire Trace that's been around for donkeys years..... sealed tubes full of one of a number of extinguishant gasses and when the tube ruptured due to heat the gas is released directly on the flame. Were used in trunking and distribution boards etc and also around engine compartmets and similar. As the installations got bigger you could add a cylinder on the end of the tube to give you more gas .......

It's the same methodology as Firetrace yes, it sounds like it's filled with Novec 1230 or similar although the suppliers MSDS gives nothing away.

This is the system: https://envirograf.com/product/enviroburst-automatic-fire-suppression-system/

Ah yes Fire Trace - this is coming back to me now. I have seen that installed in a basement, where the wooden floor was too uneven to be underscored with fire rated material and the solution was a an extinguishing system. My concern though is people using them to avoid having to remove MBCs from the board to check their manufactories date (when recall is suspected).
