6. PORTABLE FIRE
EXTINGUISHERS
SL
.NO
TYPE OF
EXTINGUISHER
ACTION
1 CARBON DIOXIDE
TYPE
1..REDUCES OXYGEN CONTENT OF THE SORROUNDINGS
2..COOLS THE FLAMES WHEN THE GAS IS PROJECTED AT THE SEAT OF
THE FIRE
2 FOAM TYPE 1.FORMS A BLANKET OF GAS FILLED BUBBLES ON THE SURFACE OF
THE BURNING LIQUIDS.
2.ISOLATES ATMOSPHERIC AIR FROM THE LIQUID
3.WATER CONTENT OF THE FOAM COOLS THE BURNING LIQUID AND
SMOOTHENS LIQUID VAPORISATION DUE TO ABSORPTION OF LATENT
HEAT
3 DRY CHEMICAL
POWDER TYPE
1.POWDER FILLS THE GAP BETWEEN THE CHARGED RADICALS OF
BURNING MATERIAL AND STOPS COMBINATION OF THE RADICALS AND
THE CHAIN REACTION &HENCE THE FIRE.
2.POWDER ALSO FORMS CLOUD AROUND THE BURNING MATERIALAND
CUTS OFF ATMOSPHERIC OXYGEN
4 HALON COOLS THE SORROUNDINGS AND PREVENTS CHAIN REACTION

7. CLASSES OF FIRE &EXTINGUISHERS TO BE
USED
CLASS OF FIRE MATERIAL TYPE OF FIRE
EXTINGUISHER TO
BE USED
