How to Use a Fire Extinguisher - Fire Safety Training
Summary
TLDRThis video script outlines key safety guidelines for operating a fire extinguisher. It explains the three elements of fire—fuel, oxygen, and ignition—and emphasizes removing any of these to stop a fire. The four fire categories (Class A, B, C, D) are described, along with steps to operate a fire extinguisher, including pulling the safety pin, aiming at the base, and sweeping the hose. Important precautions are highlighted, such as not using water on electrical fires and handling CO2 extinguishers with care. Viewers are urged to call emergency services if the fire is uncontrollable.
Takeaways
- 🔥 Fire occurs due to three main factors: fuel, oxygen, and a source of ignition.
- 🚫 By removing any one of these three elements (fuel, oxygen, ignition), the fire can be stopped.
- 📋 Fire is categorized into four classes: Class A (solid fires like wood and paper), Class B (flammable liquid fires), Class C (flammable gas fires like LPG), and Class D (metal fires).
- 🔌 In case of an electrical fire, always shut down the power source before addressing the fire.
- 🧯 To operate a fire extinguisher, first read the labels and instructions for proper use.
- 🔓 Pull the safety pin, point the hose at the base of the flames, and press the lever to release the extinguishing agent.
- ⬅️ Move the hose side to side to cover the fire surface until it is fully extinguished.
- 📞 Call emergency services immediately if the fire is beyond your control.
- 💧 Do not use water to extinguish electrical fires as it may cause electric shock.
- ❄️ Be cautious when using carbon dioxide extinguishers, as the hose and cylinder can become extremely cold and may cause cold burns.
Q & A
What are the three main components needed for a fire to occur?
-The three main components needed for a fire to occur are fuel, oxygen, and a source of ignition.
How can a fire be stopped according to the transcript?
-A fire can be stopped by removing any one of the three components: fuel, oxygen, or the source of ignition.
What are the four classes of fire mentioned in the transcript?
-The four classes of fire are: Class A (solid fires like wood, clothes, rubber, and paper), Class B (fires caused by flammable liquids), Class C (fires due to flammable gases like LPG), and Class D (metal fires).
What should be the first step when using a fire extinguisher?
-The first step is to read the labels and learn how to operate the fire extinguisher.
What is the correct method to operate a fire extinguisher?
-To operate a fire extinguisher, pull the safety pin, aim the hose at the base of the flames, press the hand lever, and sweep the hose left and right across the fire until it is extinguished.
What should you do if the fire is beyond your control?
-If the fire is beyond your control, you should call emergency services immediately.
Why should water not be used to extinguish fires on electrical equipment?
-Water should not be used on electrical fires because it can conduct electricity and cause an electric shock.
What precautions should be taken when using a carbon dioxide fire extinguisher?
-When using a carbon dioxide extinguisher, avoid touching the metallic parts because they can become very cold and cause cold burns. Handle the hose correctly without obstructing the access to the fire extinguisher.
What should you do if you do not know how to fight a fire?
-If you do not know how to fight a fire, you should seek help immediately.
What is the importance of identifying the category of fire before using an extinguisher?
-Identifying the category of fire is important because it determines the appropriate type of fire extinguisher and method to use. Using the wrong type of extinguisher could be ineffective or dangerous.

🧯 Fire Extinguisher Operation and Precautions
This paragraph provides an overview of fire extinguisher usage and safety measures. It explains that fires require fuel, oxygen, and a source of ignition to burn, and that removing any of these elements can stop a fire. The paragraph categorizes fires into four classes: Class A for solid materials like wood, clothes, rubber, and paper; Class B for flammable liquids; Class C for flammable gases like LPG; and Class D for metal fires. It advises to shut down power in case of electrical fires. The method to operate a fire extinguisher is outlined, which includes pulling the safety pin, aiming the hose at the base of the flame, and pressing the hand lever while moving the hose left and right until the fire is out. It also emphasizes calling emergency services if the fire is uncontrollable. Special precautions are highlighted, such as not using water on electrical fires to avoid electric shock, and handling carbon dioxide cylinders with care to prevent cold burns. The paragraph concludes with a reminder not to obstruct access to fire extinguishers and to seek help if unsure about firefighting.

Highlights
There are three main reasons for a fire: fuel, oxygen, and source of ignition. By removing any one of these, we can stop the fire.
Fire is categorized into four classes: Class A (solid fires), Class B (flammable liquids), Class C (flammable gases), and Class D (metal fires).
Class A fire includes solid materials like wood, clothes, rubber, and paper.
Class B fire is caused by flammable liquids.
Class C fire is due to flammable gases like LPG.
Class D fire involves metals.
In case of a fire caused by electricity, shut down the power before extinguishing.
Method to operate a fire extinguisher: First, read the labels and learn how to operate it.
Pull the safety pin of the fire extinguisher cylinder.
Aim the hose of the extinguisher at the base of the flame.
Press the hand lever and move the hose left and right over the surface of the fire until it is extinguished.
Call emergency services immediately if the fire is beyond your control.
Do not use water to extinguish fires involving electrical equipment to avoid electric shock.
When using carbon dioxide fire extinguishers, be cautious as the cylinder and hose can become extremely cold, potentially causing cold burns.
Always hold the hose at the right places and never obstruct access to fire extinguishers.

special precaution to be kept during
firefighting don't use water for
extinguishing fire on electrical
equipment it may give electric shock
while using carbon dioxide cylinders
cylinder and hose become very cool which
may cause cold burn therefore use it
without touching metallic parts with
