Fire Fighting MCQs Quiz | Class 9

Understanding Fire Fighting Basics

Fire fighting is a critical life-saving skill, especially for NCC cadets who are trained to be responsible and prepared citizens. Understanding the basics of fire, its types, and how to control it can prevent disasters and save lives. This knowledge is not just for emergencies but also for promoting a culture of safety in our daily lives.

The Fire Tetrahedron

For a fire to start and sustain itself, four elements are required. This is known as the Fire Tetrahedron, an extension of the older ‘Fire Triangle’ concept. Removing any one of these elements will extinguish the fire.

• Fuel: Any combustible material like wood, paper, oil, or gas.
• Heat: An ignition source that raises the fuel to its ignition temperature.
• Oxygen: The air we breathe contains about 21% oxygen, which is usually sufficient to support combustion.
• Chemical Chain Reaction: The process that allows the fire to sustain itself and grow.

Classes of Fire

Fires are classified based on the type of fuel they burn. Using the wrong type of fire extinguisher can be ineffective and even dangerous. It’s crucial to identify the class of fire before attempting to extinguish it.

Essential Do’s and Don’ts in a Fire Emergency

Do’s:

• RAISE THE ALARM: Alert everyone immediately by shouting “Fire! Fire!”. Activate the nearest fire alarm.
• STAY CALM: Panic can lead to poor decisions. Try to remain calm and think clearly.
• EVACUATE: Leave the building immediately using the nearest safe exit. Do not stop to collect personal belongings.
• CRAWL LOW: If there is smoke, stay low to the ground where the air is cleaner and cooler.
– STOP, DROP, AND ROLL: If your clothes catch fire, do not run. Stop immediately, drop to the ground, cover your face with your hands, and roll over and over to smother the flames.
• FEEL DOORS: Before opening a door, feel it with the back of your hand. If it’s hot, do not open it. Find another way out.

Don’ts:

• DON’T USE ELEVATORS: Lifts and elevators can trap you during a fire. Always use the stairs.
• DON’T RE-ENTER: Never go back into a burning building for any reason. Inform the firefighters if someone is trapped inside.
• DON’T USE WATER ON ALL FIRES: Never use water on electrical fires or fires involving flammable liquids (like oil or grease), as it can make the situation worse.
• DON’T HIDE: Do not hide in closets or under beds. Try to get out. If you are trapped, go to a room with a window and a phone. Close the door and block the cracks to keep smoke out. Signal for help from the window.

Quick Revision Points

• The four elements of fire are Fuel, Heat, Oxygen, and a Chemical Chain Reaction (Fire Tetrahedron).
• The acronym for using a fire extinguisher is P.A.S.S. (Pull, Aim, Squeeze, Sweep).
• Know the emergency exit routes in your home, school, and other familiar places.
• Smoke is more dangerous than flames in many fire situations. Avoid inhaling it by staying low.
• Regularly check and maintain fire safety equipment like smoke detectors and fire extinguishers.
