Faster the action, better it is;

Neighbour is always at a closer distance than the

nearest relative. Hence in case of need, one who isalways present at site can act in a faster way than

F& S personnel who wil l certainly take some time

to reach the spot

(i) 2NaHCO3 -> Na2O + CO2 + 2H*

(i i) Free H* from DCP combines with OH* of fuel,

which is also a chain carr ier, to absorb OH* andinhibit the chain reaction:

OH* + H* -> H2O

CO2 EXTINGUIHERS


20/24

Learn proper method of operation of F ire extinguishers.

Always use r ight type of Extinguisher/ Extinguishing media on

fire.

Always keep safe distance from flames, whi le operating f ire

extinguishers.

Agent should be continued applying even after the flames

extinguished, in order to allow time for cooling and to prevent

re-ignition.

FIRE EXTINGUIHERSDOS & DONTS


21/24

Dont enter confined space to extinguish fire with fireextinguisher.

Always secure discharge tube in one hand before operating the

extinguisher.

Dont approach from downwind direction to extinguish fire.

Attack seat of f ire, sweeping the nozzle rapidly from side to side.

Hand over the discharged extinguisher to f ire service staff . So

that it can be recharged in time.



22/24

I f you see any fi re extinguisher lying in improper

condition/location, immediately bring i t in the notice of F ire

Services.

Dont get panicky, if CO2 /DCP decreases visibility in operating

area.Dont bend over DCP fire extinguisher while operating it.

While operating any extinguisher if the powder does not come

out even after plunger/Lever is being pressed, dont try to openthe extinguisher, as it may be pressurized with CO2 gas. I nform

fire service personnel about that extinguisher and keep it away,

lying on floor.



23/24

I f CO2/ Halon extinguisher is to be used in a conf ined area,

precautions should be taken so that people are not overcome

because of lack of oxygen.

Dont get afraid-of sound produced by extinguisher (Special ly

CO2 extinguisher).

Dont touch the discharge horn during operation of CO2

extinguisher, because it can became extremely cold.

Dont direct the initial discharge directly at burning surface

(Specially flammable liquids) at close range because the high

velocity of the stream may splash or scatter the burning mater ial.
