Afire extinguisher is useless in an emergency unless the person can use it. true or false

The answer is true. A fire extinguisher is a dynamic fire assurance gadget used to stifle or control little flames, regularly in crisis circumstances. It is not planned for use on a crazy fire, for example, one which has achieved the roof, imperils the client or generally requires the aptitude of a fire office.

Yes, its true that a fire extinguisher is useless in an emergency unless the person can use it. Fire extinguishers are used in emergency fire-breakouts. But, there is no utility of this emergency device if it can be used in a sitatution of emergency. It must remain in active working mode to prevent fire.
