Purple-K

This fire Purple K extinguishing agent are used in military facilities, oil companies and vehicles, etc.
Purple is a dry chemical called potassium bicarbonate that is non-conductive and non-corrosive,
and can be cleaned up by vacuuming, sweeping or flushing with water.
Purple, is a potassium bicarbonate base dry-chemical fire suppression agent used in some dry powder fire extinguishers.
It is the most effective dry chemical in fighting class B (flammable liquid) fires,
and can be used against some energized electrical equipment fires (class C fires).
It is at least 5 times more effective against class B fires than carbon dioxide and has about twice the effectiveness of sodium bicarbonate based powders.
This is due to the larger size of the potassium ion.
Purple K Dry Chemical Powder (DCP) works by directly inhibiting the chemical chain reaction in the combustion zone of flammable liquid fires
which forms one of the four sides of the Fire tetrahedron (Heat + Oxygen + Fuel + Chemical Chain Reaction = Fire)
This chemical reaction produces ‘free radicals’ which attach themselves to
the surface of the powder particles introduced into the combustion zone.
