What is Water Fire Extinguisher used for? How Does Water Extinguisher Work – This article is going to give you information with respect to Water Fire Extinguishers. In this article, you will get to know each and every kind of detail. this article will be helpful to you. So, read this article fully.
What is Water Fire Extinguisher used for?
Water fire extinguishers are used to extinguish fires caused by combustible materials, such as wood, paper, and fabric. They work by removing the heat energy that is necessary for combustion to occur, thereby cooling the fire and extinguishing the flames.
Water extinguishers are also known as “water pressure extinguishers” or “water hose reel extinguishers”. They contain water under pressure and when the nozzle is activated, the water is released as a powerful stream that can be directed at the base of the fire. This cools the fire, removing the heat energy that is necessary for combustion to occur and extinguishing the flames.
It is important to note that water extinguishers should only be used on Class A fires, which are fires caused by combustible materials, and not on fires caused by flammable liquids or electrical equipment as they may cause more damage. Additionally, they are not recommended for use on fires in enclosed spaces as they can cause a buildup of steam and increase the risk of injury.
How Does Water Extinguisher Work?
A water extinguisher works by using high pressure to spray water on a fire, which cools down the fire and starves it of oxygen. This type of extinguisher is primarily used to extinguish fires that involve ordinary combustibles such as wood, paper, and cloth. It is not effective on fires caused by flammable liquids or gases, or on electrical fires. Water extinguishers have a label with a green triangle with the letter “W” in it.
A water extinguisher typically has a cylindrical body filled with water and pressurized gas, such as air or nitrogen. The pressurized gas is used to force the water out of the extinguisher through a nozzle, creating a high-pressure stream of water. The stream of water is directed at the base of the fire, where it cools down the fire and removes the heat energy that is fueling it. This causes the fire to die down and eventually go out.
Water extinguishers are relatively simple and inexpensive, and they are easy to use. However, they have some drawbacks. For example, they can cause damage to electrical equipment, and they can create a lot of water damage if used indoors. Additionally, they are not very effective on deep-seated fires, such as fires that have spread to the walls or ceiling of a room.
Overall, water extinguishers are a good choice for fires that involve ordinary combustibles, such as wood, paper, and cloth. They are not recommended for use on fires caused by flammable liquids or gases, or on electrical fires. If you’re not sure what type of fire extinguisher to use, it’s always best to consult a professional.
What Colour is Water Fire Extinguisher?
Water-type fire extinguishers are typically red in colour. According to international standards, ISO 7010, red is the colour used for fire-fighting equipment and fire-extinguisher symbol. This colour code applies to all types of fire extinguishers, including water types. This helps to easily identify the type of extinguisher and the type of fire it is suitable for in an emergency situation.
Pros of Water Fire Extinguishers
- Affordable: Water extinguishers are relatively inexpensive and easy to maintain. They do not require any special training or certification to operate and they can be refilled with water after each use.
- Easy to use: Water extinguishers are simple to operate and require no special training or certification.
- Quick response: Water extinguishers can be used quickly, making them an ideal solution for emergency situations where time is of the essence.
- Portable and lightweight: Water extinguishers are small, lightweight and easy to store, making them ideal for use in both residential and commercial settings.
- Safe: Water extinguishers are designed to be used by anyone, regardless of their level of training or experience.
Cons of Water Fire Extinguishers
- Limited use: Water extinguishers are intended for use on Class A fires (fires caused by combustible materials) only, and not on fires caused by flammable liquids or electrical equipment as they may cause more damage.
- Limited coverage: Water extinguishers release a limited amount of water, so they may not be able to put out large fires or cover a wide area.
- Not recommended for use in enclosed spaces: Water extinguishers are not recommended for use on fires in enclosed spaces as they can cause a buildup of steam and increase the risk of injury.
- May cause damage to sensitive equipment: Water extinguishers may cause damage to electronic and other sensitive equipment.
- Not effective in all types of fires: Water extinguishers may not be effective in putting out fires caused by certain types of materials, such as cooking oils or chemicals.
