Water may be the most readily available tool for extinguishing a fire, but did you know that not all fires can be put out safely with water? In this article, we’ll explore the different types of fires and what type of fire can be put out safely with water, so you can be prepared in case of an emergency.
Water is most commonly used to extinguish fires that involve combustible materials such as wood, paper, and cloth. These types of fires are called Class A fires, and they can be safely put out by applying water to the burning material.
It’s important to note that water should not be used to extinguish fires that involve flammable liquids or gases, electrical equipment, or certain types of chemicals. These types of fires are called Class B, C, and D fires, respectively, and they require specialized fire extinguishers or other fire suppression methods.
What type of fire can be put out safely with water?
Water can be used to extinguish fires that are classified as Class A fires, which are fires that involve ordinary combustibles such as wood, paper, cloth, rubber, and some plastics.
These types of fires are typically caused by heat and can be put out by removing the heat or by cooling the burning materials. Water is an effective tool for removing heat because it has a high heat capacity, which means that it can absorb a lot of heat energy before it begins to increase in temperature.
It’s important to note that water should not be used to put out fires that are classified as Class B or C fires. Class B fires are fires that involve flammable liquids and gases, and Class C fires are fires that involve electrical equipment.
Water is not effective for putting out these types of fires and can actually make them worse. For example, using water to put out a fire involving flammable liquids or gases can cause the fire to spread, and using water to put out a fire involving electrical equipment can cause electrocution.
Other than class A fire, also some class D fire which is a fire that involves combustible metals, can be put out by the water, but only by using a special type of water, that is known as ‘Foam,’ which is a mix of water, foam concentrate, and air. The foam smothers the fire and forms a barrier that prevents oxygen from reaching the burning metal.
It’s important to always be aware of your surroundings and the potential hazards and to familiarize yourself with the appropriate methods for extinguishing different types of fires. If you are ever in a situation where you need to put out a fire, it’s important to call emergency services right away and follow their instruction.
Fires you can’t put out with water
There are several types of fires that cannot be extinguished using water. These include:
- Electrical fires: These fires are caused by electrical equipment or wiring and are best put out using a fire extinguisher specifically designed for electrical fires, such as one containing a dry powder agent.
- Flammable liquid fires: Fires caused by flammable liquids, such as gasoline or oil, are best extinguished using a fire extinguisher containing a foam or dry powder agent. Water can actually spread the fire in this case.
- Cooking oil fires: Fires caused by cooking oil, such as in a deep fryer, should never be put out with water. Instead, use a fire extinguisher specifically designed for kitchen fires, or turn off the heat source and use a lid or baking soda to smother the fire.
- Metal fires: Fires involving burning metal, such as magnesium or titanium, should not be put out with water as the reaction between water and certain metals can be violent and can cause the fire to spread.
- Class D fires: This type of fire involve combustible metals like lithium, sodium, and potassium. Due to the chemical reaction between these metals and water, using water to extinguish the fire can be dangerous and ineffective.
In general, it’s important to know the type of fire you are dealing with and use the appropriate extinguishing agent. If you’re unsure, it’s best to evacuate the area and call the fire department for assistance.
Putting out kitchen fires with water
It is not safe to put out kitchen fires with water. Water is not an effective extinguishing agent for fires caused by cooking oils or fats, such as those that can occur in a deep fryer or on a stovetop. When water is added to hot oil, it can cause the oil to splash and spread the fire, which can lead to severe burns and other injuries.
The best way to extinguish a kitchen fire is to turn off the heat source, if possible, and use a lid or baking soda to smother the fire. You can also use a fire extinguisher specifically designed for kitchen fires, which typically contains a dry powder or foam agent.
It’s also important to have a fire extinguisher in the kitchen and know how to use it properly. When using a fire extinguisher, remember the acronym “PASS,” which stands for:
- Pull the pin at the top of the extinguisher
- Aim the nozzle at the base of the fire
- Squeeze the handle to release the extinguishing agent
- Sweep the nozzle back and forth across the base of the fire
If you’re unable to extinguish the fire or if it starts to spread, evacuate the area and call the fire department immediately.
Another tip is to never leave cooking food unattended and keep flammable materials such as paper or curtains away from the stove or heat sources.
Extinguishing electrical fires with water
It is not safe to use water to extinguish electrical fires. Water conducts electricity and can cause electrical shock or even electrocution. Additionally, water can cause the electrical equipment or wiring to short circuit, which can cause the fire to spread.
To safely extinguish an electrical fire, you should use a fire extinguisher specifically designed for electrical fires, such as one containing a dry powder agent. These types of extinguishers are labeled as “Class C” fire extinguishers, and they are safe to use on electrical equipment.
The dry powder extinguishing agent works by smothering the fire, cutting off the oxygen supply, and also cooling down the equipment, and the extinguisher works by creating a barrier between the oxygen in the air and the fire, effectively smothering the flames.
If the fire is too large or you’re unable to extinguish it safely, you should evacuate the area and call the fire department immediately.
If you don’t have a fire extinguisher specifically for electrical fires, or if you are unsure of how to safely extinguish the fire, it’s best to unplug or turn off the power source if possible and evacuate the area. If the fire is too large or if you’re unable to turn off the power, call the fire department and wait for their arrival.
Therefore, it’s essential to have fire safety equipment in your workplace or home, to know their proper use, and also to have an evacuation plan in case of emergency.
Using water to extinguish fires in a fireplace or wood stove
Using water to extinguish fires in a fireplace or wood stove is not typically recommended, as it can damage the fireplace or wood stove and create a buildup of dangerous creosote in the chimney. Additionally, water can cause the fire to spread, creating a bigger and potentially more dangerous fire.
The best way to extinguish a fire in a fireplace or wood stove is to simply close the damper and the doors and let the fire die out on its own. This will prevent the fire from getting oxygen and will allow it to burn out naturally.
If you are concerned about the fire spreading, you can also place a metal fire screen in front of the fireplace or wood stove to contain the fire.
If the fire is too large or you’re unable to extinguish it safely, you should evacuate the area and call the fire department immediately.
A good practice to avoid fires in your fireplace is regular cleaning and maintenance of the chimney and also making sure you have the proper type of wood; dry and seasoned woods burn cleaner, slower and hotter, which can decrease the amount of creosote buildup, if you burn wet or green wood creosote can buildup and the chimney could catch fire.
It’s also important to not overload your wood stove or fireplace and to always use a metal grate to elevate the wood off the ground and to allow air to circulate underneath, preventing the wood from smoldering.
Dousing car fires with water
Using water to extinguish a car fire is generally not recommended. Water can cause damage to the electrical components of a car and may not effectively extinguish the fire. Additionally, water can also cause a short circuit in the electrical system and could cause the fire to spread.
The best way to extinguish a car fire is to use a fire extinguisher specifically designed for vehicle fires, such as one containing a dry powder agent.
These types of extinguishers are labeled as “Class B” fire extinguishers, and they are safe to use on flammable liquids such as gasoline and oil. The dry powder extinguishing agent works by smothering the fire, cutting off the oxygen supply, and also by cooling down the equipment.
If you don’t have a fire extinguisher or if you’re unable to safely extinguish the fire, the best course of action is to evacuate the area and call the fire department immediately.
If you’re driving and your car catches fire, you should pull over to a safe location, turn off the engine, and get out of the car as quickly as possible. If possible, you should then use a fire extinguisher to put out the fire or call the fire department and wait for their arrival.
It’s important to have fire extinguishers in your vehicle and have knowledge of how to use them. In addition to this, it’s good to know that maintaining your car in good condition, regular check-ups and tune-ups, and checking for oil or fuel leaks are critical, especially for older cars.
Putting out fires in waste bins or trash cans with water
