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.
