Questions on Fire Safety

Here are some important questions on Fire safety. We all should know the answers to these questions for our safety.

• How does water act as a fire suppressing agent?

Ans: When water is sprayed on fire, it absorbs the heat and is converted into steam. Then, its’ volume increases 1600 times. This phenomenon helps to displace the oxygen from the fire area. This results in oxygen depletion in the fire area. Thus water acts as a fire suppressing agent.

• What are the main purposes of sprinklers?

Ans: the two main purposes of Sprinklers are:

To extinguish the unwanted fire and to control the size of a fire until skilled fire suppression crews reach the spot to extinguish the fire.

• What is a fire hydrant valve?

Ans: A fire hydrant is simply like a valve that you have found in water taps. It provides constant water flow. When you connect the fire hose with this valve, pressurized water will flow to extinguish the fire.

• What are deluge valves?

Ans: Deluge valves provide pressurized water from Fire Sprinklers.

• What is the fire fighting equipment?

Ans: Fire fighting equipment is the Fire alarm, Sprinklers, Standpipe and Hose Systems, Fire extinguishers, etc.  There are different types of fire extinguishers. They are water, carbon dioxide, ABC Dry powder, Dry powder, Foam based extinguisher, and clean agent fire extinguisher.

• What are the rules you should follow for using a portable fire extinguisher?

Ans:  The general rules you should follow for using the portable fire extinguishers are:

In the upwind direction, you should fight with the fire.

1. Handle the fire, maintaining a safe distance of approximately 2 to 5 meters from the flame.
2. Follow the PASS system:  P for pulling the pin, A for aiming at the base of the fire, S for squeezing the fire, and S for sweeping side to side.
3. Stay sometimes even after vanishing the fire completely. If the fire re-ignites, repeat the process.
4. Do not leave the fire area till you are sure that the fire is completely extinguished.

• Which actions should you take when you discover a fire?

Ans:  You should take the following necessary actions immediately:

1. Ring the alarm and then get everyone out of this zone.
2. Try to extinguish the fire and simultaneously call the fire brigade.
