{"Image DocumentName": "FIRE TRIANGLE Fuel Oxygen Ignition Sources/Heat", "Image ImageDescription": "Flammable gases Flammable liquids Flammable solids. Oxygen. Air we breath (21% O2) Additional sources from oxidising substances & cylinders. All fires comprise these three elements. All extinguishers work by removing or reducing one or more of the elements. What element would a water PFE be used on? Ignition Source/Heat. Where would a CO2 extinguisher be used (indoors or out) \u2013 Indoors. It works by reducing the O2 in the atmosphere. Would it be safe to be in a room if a CO2 was let off? Generally yes as the O2 needs to be reduced to around 17% before people are affected. O2 levels of around 14% present a real life risk.
