What is Purple K and what is it used for?
Purple K powder is a dry chemical fire suppression agent and its main component is potassium bicarbonate.
It is commonly used in fighting fires that involve flammable liquids (Class B fires) and is much more effective than carbon dioxide (CO2) for those types of fire.
Purple K, including in a Purple K Fire Extinguisher, works by chemically interfering with the combustion that allows a fire to start, i.e., it stops heat, fuel and oxygen from reacting together to make a fire.
It works best on Class B & Class C fires, however, it is NOT recommended for use in confined areas and also, whilst normally non-toxic, it can cause alkalosis if large amounts are ingested.
Purple K is most commonly used where large amounts of flammable liquids are handled, typically around oil refineries, airports, military establishments and power stations.
