Types of fire extinguishers and how to maintain them
Fire extinguishers are considered one of the most important basic safety tools in homes, companies, factories, warehouses, and commercial and industrial facilities. Having the right extinguisher and using it correctly may prevent the spread of fire, preserve lives and property, and significantly reduce losses.
In this comprehensive guide, we will learn about the types of fire extinguishers, the uses of each type, fire symbols and classifications, as well as the best methods of inspection and periodic maintenance to ensure their readiness in times of emergency.
First: What is a fire extinguisher?
A fire extinguisher is a device containing a substance designed to extinguish fires in their early stages before they spread. Fire extinguishers vary depending on the substance they contain and the type of fire they are designed to combat.
Second: What are the classifications of fires?
Before choosing the right fire extinguisher, you must know the type of fire, as fires are divided globally into several categories:
- Class A fires include: Wood, paper, fabrics, plastic, cardboard. These are fires involving flammable solid materials.
- Class B fires include: Gasoline, diesel, oils, solvents, paints. These are fires involving flammable liquids.
- Class C fires include: Electrical equipment, control panels, generators, electrical cables.
- Class D fires include: Flammable metals such as: magnesium, sodium, titanium. They are often found in heavy industries and factories.
- Class K&F fires include: Cooking oils, vegetable and animal fats. They are widespread in restaurants and commercial kitchens.
Third: Types of fire extinguishers
1. Water Fire Extinguisher.
Usage: It is used for Class A fires only.
Features: Low cost, effective for solid materials, easy to use.
Disadvantages: Not suitable for electrical fires; dangerous when used with flammable liquids.
2. Foam Extinguisher.
Usage: Class A fires, Class B fires.
How it works: It forms a foam layer that prevents oxygen from reaching the ignition source.
Common uses: Gas stations, warehouses, factories.
3. CO2 fire extinguisher.
Usage: Electrical fires, fires involving flammable liquids.
Features: Leaves no residue after being turned off, suitable for server rooms and electrical panels.
Disadvantages: Ineffective in open spaces; may cause suffocation in enclosed spaces.
4. Dry Powder Fire Extinguisher.
Usage: It is considered one of the most widespread fire extinguishers because it covers: Category A, Category B, Category C.
Features: Versatile, efficient and fast.
Disadvantages: It leaves behind powder residue that may affect electronic devices.
5. Wet Chemical Extinguisher.
Usage: Specifically designed for kitchen and oil fires.
Uses: Restaurants, hotels, commercial kitchens.
Features: It prevents reignition and is very effective with cooking oils.
Fourth: How to choose the right fire extinguisher?
The choice of fire extinguisher depends on several factors:
1. Type of establishment: Homes, factories, hospitals, restaurants, gas stations.
2. Type of risk: Electrical hazards, flammable materials, oils and greases, chemicals.
3. Space size: The larger the area, the more fire extinguishers are required.
Fifth: How to use a fire extinguisher?
The universal method is based on the PASS rule:
- P – Pull (Pull the safety pin).
- A – Aim (point the hose towards the fire base).
- S – Squeeze (Press the handle).
- S – Sweep (Move the spray right and left until the fire goes out).
Sixth: The importance of fire extinguisher maintenance.
Having a fire extinguisher without maintenance can render it ineffective in the event of a fire; therefore, regular maintenance is essential in safety systems. Maintenance objectives:
– Make sure the fire extinguisher is ready.
- Maintaining internal pressure.
– Detecting leaks and malfunctions.
– Compliance with the requirements of the Civil Defense.
Seventh: Types of fire extinguisher maintenance
1. The monthly check-up includes:
– Make sure the fire extinguisher is in its place.
– Check the blood pressure gauge.
– Checking the safety of the hose.
- Check for rust or damage.
– Check that the safety pin is intact.
2. Annual maintenance includes:
- Unload and inspect the fire extinguisher.
- Refilling if necessary.
- Checking the valve and internal parts.
– Pressure test.
– Place the maintenance sticker.
3. Hydrostatic test:
Every few years, depending on the type of fire extinguisher, it is checked to ensure the cylinder can withstand the pressure.
Eighth: Signs that indicate the fire extinguisher needs maintenance:
– A decrease in blood pressure.
- The presence of rust or cracks.
- Damaged Hose.
– The nozzle is blocked.
– Expiration date.
– Loss of the safety pin.
Ninth: Common mistakes in using fire extinguishers
- Using the wrong type of fire extinguisher, such as using water on an electrical fire.
- Lack of employee training; many people do not know the correct way to use it.
Neglecting regular maintenance may lead to the fire extinguisher failing during an emergency.
Fire extinguishers should be placed in inappropriate locations that are clearly visible and easily accessible.
Tenth: Important fire safety tips:
– Training employees on how to use fire extinguishers.
- Conduct a monthly check-up.
– Installation of fire alarm systems.
– Ensure that fire extinguishers are easily accessible.
- Use the appropriate fire extinguisher for each hazard.
- Do not use the fire extinguisher after its expiry date.
Conclusion:
Fire extinguishers are the first line of defense against fires, and choosing the right type along with adhering to periodic maintenance greatly contributes to protecting lives and property and reducing losses.
Whether you are a homeowner, business owner, or factory owner, investing in safety systems and fire-fighting equipment is not a secondary option, but an essential necessity to ensure a safe environment that complies with safety and civil defense requirements.
