Water Type Fire Extinguisher Full Specifications A water type fire extinguisher is one of the most widely used and effective tools for suppressing fires, particularly Class A fires. These fires involve ordinary combustibles like wood, paper, and textiles. This article outlines the specifications, features, and applications of water fire extinguishers. It will help you understand their importance and how to use them properly in emergencies.

What is a Water Type Fire Extinguisher?

A water fire extinguisher uses water as the primary agent to extinguish fires. When discharged, water cools the burning material, lowering the temperature below its combustion point and putting out the fire. Water extinguishers are especially effective against Class A fires, which involve solid combustibles like paper, wood, fabric, and plastic. However, they are unsuitable for Class B (flammable liquids) and Class C (electrical) fires.

Water Type Fire Extinguisher Specifications

Here is a breakdown of the key specifications for water fire extinguishers:

1. Capacity

Water extinguishers typically come in the following sizes:

• 2L, 4L, 6L, and 9L.
• The 9L model is the most common for residential and office use. Smaller units, such as the 2L, are ideal for areas with low fire risk or limited space.

2. Discharge Time

• A 9L water extinguisher typically discharges for 30 to 60 seconds.
• Smaller units, like the 2L, discharge for 20 to 30 seconds.

3. Discharge Range

• The discharge range for water extinguishers is typically between 6 to 9 meters (about 20 to 30 feet). This varies depending on the extinguisher’s size and nozzle design.

4. Operating Pressure

• Most water fire extinguishers operate at 10 to 12 bar of pressure at 15°C. This ensures the water is released with enough force to effectively suppress the fire.

5. Temperature Range

• Water extinguishers are most effective in temperatures ranging from -5°C to 60°C.
• It’s crucial to store these extinguishers in areas that don’t drop below freezing, as water can freeze and damage the extinguisher.

6. Material

• Water extinguishers are made from high-quality steel, ensuring durability and resistance to rust.
• The discharge nozzle and hose are made from materials like brass or aluminum for reliable operation.

7. Fire Class

Water extinguishers are designed for Class A fires, including:

• Wood, paper, textiles, plastics, and other solid combustibles.
• They should never be used on Class B (flammable liquids) or Class C (electrical) fires.

8. Maintenance and Service

Regular inspection and maintenance are essential to keep water extinguishers in proper working condition. Inspections should be performed every 6 to 12 months and should include:

• Checking the pressure gauge.
• Ensuring there are no leaks.
• Verifying the nozzle is free of blockages.

Features of Water Type Fire Extinguishers

1. Easy to Use

Water extinguishers are simple to operate, making them ideal for both homes and offices. The procedure is straightforward: pull the pin, aim at the base of the fire, and squeeze the handle to discharge the water.

2. Effective Against Solid Combustibles

Water extinguishers are particularly effective against Class A fires. Water works by cooling the burning material, quickly reducing the heat and extinguishing the fire.

3. Low Cost

Compared to other fire extinguishers like CO2 or foam, water extinguishers are affordable. They offer an economical solution for handling common fire hazards.

4. Minimal Residue

Water extinguishers leave minimal residue, making cleanup easy. This is important in environments such as homes, offices, and workplaces where quick restoration is necessary.

5. Environmentally Friendly

Since water is a natural and non-toxic substance, water extinguishers are safe for the environment and for the people who use them.

Advantages of Water Type Fire Extinguishers

1. Cost-Effective: Water fire extinguishers are one of the most affordable fire safety tools, making them an excellent choice for many settings.
2. Simple Operation: These extinguishers are easy to use, even for individuals with minimal fire safety training.
3. Widely Available: You can find water extinguishers in most retail stores, making them easily accessible for homeowners and businesses alike.
4. Ideal for Class A Fires: Water extinguishers provide excellent protection against Class A fires, which are common in residential, office, and industrial environments.
5. Low Environmental Impact: Water does not release harmful chemicals, making these extinguishers an eco-friendly choice.

Applications of Water Type Fire Extinguishers

1. Residential Use

Water extinguishers are ideal for homes where fires involving ordinary combustibles like paper, wood, and textiles are most likely. You will often find them in kitchens, living rooms, and garages.

2. Offices

In office settings, water extinguishers are effective against fires caused by paper and cardboard. A 9L unit is ideal for most office environments.

3. Warehouses and Storage Facilities

Water extinguishers work well in warehouses that store paper products, textiles, or wooden materials. However, they should not be used in areas with flammable liquids or electrical equipment.

4. Schools and Educational Institutions

Water extinguishers are commonly used in schools because they effectively handle fires involving books, papers, and classroom furniture—all typical Class A materials.

How to Use a Water Type Fire Extinguisher

1. Pull the Pin: Remove the safety pin from the handle to unlock the extinguisher.
2. Aim at the Base: Point the nozzle at the base of the fire. This is the most effective spot to target for extinguishing the flames.
3. Squeeze the Handle: Apply pressure to the handle to release the water. Keep a steady flow while maintaining focus on the base of the fire.
4. Sweep Side to Side: Move the nozzle from side to side to cover the entire area of the fire and ensure complete suppression.
5. Stay at a Safe Distance: Maintain a distance of 1 to 2 meters from the fire to ensure your safety.

Conclusion

Water Type Fire Extinguisher Full Specifications Water type fire extinguishers are affordable, easy to use, and effective for Class A fires. Their wide range of applications, from residential to industrial settings, makes them an essential part of fire safety. By understanding their specifications, features, and maintenance requirements, you can ensure proper fire protection for your property, family, and employees.
