Fires can happen unexpectedly, and knowing how to put them out can make all the difference. Whether it's a small kitchen fire or a bigger blaze, acting fast is the key. In this guide, we’ll explain the steps for putting out different types of fires, including grease and electrical fires. 

How to Put Out Class A Fires

Class A fires are the most common type of fire. They can happen anywhere, so you have to be careful. Find out more about Class A fires and how to put them out below. 

What is a Class A Fire?

A Class A fire is the most common. It occurs when everyday materials catch fire. These materials include wood, paper, fabric, and plastic. You’ll find these items in homes, offices, vehicles, and outdoors. For example, a Class A fire breaks out if a candle tips over a stack of magazines.

Class A fires can start easily and spread quickly, especially when there are many fire hazards around. They’re also dangerous because they can fill a room with smoke or spread through your house fast. 

Class A fires can happen anywhere―in your living room, in the kitchen, or even outside if the weather is dry. For instance, dry grass or leaves can catch fire quickly if a cigarette or spark lands on them. Find out more about Class A fires here.  

What Is a Class A Fire Extinguisher?

A Class A fire extinguisher puts out fires caused by solid materials like wood, paper, fabric, plastic, and rubber. They’re mostly filled with water, though some have additives to improve their effectiveness. For example, some may contain antifreeze to keep the water from freezing in cold temperatures. 

Class A fire extinguishers work by cooling down the fire and removing heat from the flames. This stops the fire from spreading. They’re usually marked with a green triangle with an "A" inside it. Find out more about Class A fire extinguishers here.  

How to Put Out a Class A Fire

Here’s how to put out a Class A fire:

1. Stay Calm

Panicking can cloud your judgment. Take a moment to assess the situation. If the fire is small and contained, you can try putting it out. If it’s spreading quickly or you don’t feel safe, evacuate and call for help.

2. Use the Right Tools

You can use a fire blanket, spray, or extinguisher to put out a Class A fire. 

A fire blanket is made of fire-resistant materials. Plus, it’s easy to use. Simply unfold the blanket and place it over the fire. Doing this cuts off the oxygen and quickly puts the fire out. 

You can also use a fire spray to put out Class A fires. It’s light, non-toxic, and easy to use. Simply aim the nozzle at the base of the fire and spray side to side until the fire is out.

If you have a Class A fire extinguisher and prefer using it, do so. Stand at a safe distance and follow the PASS fire extinguisher method: pull the pin, aim at the base of the fire, squeeze the handle, and sweep side to side.

3. Check for Hot Spots 

Check for any hot spots after the fire dies. It could reignite, so make sure everything is fully cool before leaving.

4. Call for Help 

If the fire is uncontrollable or you’re not confident about putting it out, evacuate and call the fire department. 

How to Put Out Class B Fires

Class B fires are more difficult to put out than other fire types. Find out more about Class B fires and how to put them out below.

What is a Class B Fire?

Class B fires are fires caused by flammable liquids and gases like gasoline, alcohol, paint, propane, and butane. These types of fires are more dangerous because the liquid can spread quickly, making the fire harder to control. While not that common, they can happen in homes, garages, or workshops. For example, a gasoline leak from a lawnmower can ignite a Class B fire. 

The main danger of Class B fires is how fast they spread. Once a fire starts, it can escalate, especially if there’s a lot of flammable liquid and gases nearby. These fires can also release toxic fumes. Common causes include spills, leaks, and improper storage.

The risk is higher in industrial settings because the fire might explode. Always store flammable liquids properly, keep them away from heat, and ventilate areas to reduce the risk of a Class B fire. Find out how to store flammable liquids and gases here. 

What Is a Class B Fire Extinguisher?

A Class B fire extinguisher puts out fires caused by flammable liquids and gases. These fires are tricky because liquids and gases can spread fire quickly. Using the wrong extinguisher, like a water-based one, can make the fire worse, so it’s important to use a Class B fire extinguisher. 

Class B extinguishers come in different types, such as foam, carbon dioxide, and powder. Foam extinguishers work best for flammable liquid fires because the foam creates a barrier and prevents it from reigniting. Carbon dioxide extinguishers displace the oxygen the fire needs to burn, while powder extinguishers coat the fuel to block oxygen and cool the flames. Find out more about Class B fire extinguishers here. 

How to Put Out a Class B Fire

Here’s how to put out a Class B fire:

1. Stay Calm

First, take a deep breath. Stay calm and assess the fire. Is it small and contained? Do you feel confident putting it out? If yes, continue with the steps below. If not, evacuate and call the authorities right away.

2. Use the Right Tools

Use a fire blanket, spray, or extinguisher to put out the fire. If you’re using a fire blanket, make sure the fire is small. If it’s too big or intense, use other tools. If you have a fire spray, aim it at the base of the fire and spray from side to side. The same steps apply to a fire extinguisher.

3. Watch Out for Reignition

Don’t walk away even if the fire is out. Check the area for any hot spots that could reignite. Make sure everything is completely cool before leaving.

4. Evacuate if Needed

If you don’t have the right tools or if the fire is spreading quickly, evacuate. Then, call 911 and tell them your location.

How to Put Out Class C Fires

Class C fires are tricky because they involve electrical equipment. Find out more about Class C fires and how to put them out below.

What is a Class C Fire?

A Class C fire is caused by electrical equipment. These fires happen when electrical devices, wiring, or circuits catch fire while connected to a live power source. As long as the electricity is running, the fire will continue burning. 

Class C fires can start anywhere with electrical equipment, including homes, offices, and even outdoor settings. They’re tricky because wires are usually hidden behind walls and ceilings. As a result, you might not notice the fire until it’s already spreading. Find out what an electrical fire smells like here. 

What makes Class C fires more dangerous is you can’t put them out with water or water-based extinguishers. Water conducts electricity, so it can shock you. That’s why it’s crucial to use the right tools, like electrical fire extinguishers, sprays, and blankets.

Common causes of Class C fires include faulty wiring, overloaded outlets, malfunctioning appliances, and heating devices. So, always check your wiring and avoid overloading outlets. Find out more about Class C fires here. 

What Is a Class C Fire Extinguisher?

A Class C fire extinguisher puts out electrical fires. Class C extinguishers use different materials to fight such fires, including carbon dioxide (CO2), powder, or water mist. CO2 is popular because it doesn't leave a mess. Since it's just air, it also won’t damage electronics. 

On the other hand, powder extinguishers work by coating the fire and cutting off the oxygen, while water mist fire extinguishers use deionized water. Deionized water doesn’t conduct electricity, so it’s safe to use on electrical fires. Never use regular water to put out an electrical fire because it can shock you. Find out more about Class C fire extinguishers here. 

How to Put Out a Class C Fire

Here’s how to put out a Class C fire:

1. Stay Calm

Panic can cloud your judgment and make things worse. Assess the situation first. If the fire is small, follow the steps below. If not, evacuate immediately.

2. Turn Off the Power

Turn off the power supply if possible. Cutting off the electricity helps stop the fire from burning. But only do this if it’s safe. 

3. Use the Right Tools

You can use a fire blanket, the Dry Stop Fire Spray, Vapor Clean Fire Spray, or an electrical fire extinguisher. If you’re using a fire blanket, carefully put it over the fire. If you’re using a fire extinguisher or spray, aim at the base of the fire and sweep from side to side.

4. Check for Hot Spots

Keep an eye on the fire after putting it out. Fires can reignite, so look for any signs of it coming back. Use your fire tools again if needed.

5. Call the Fire Department

Call the fire department if the fire is getting worse or you feel unsafe putting it out. It’s better to be safe and let the experts check it out.

How to Put Out Class D Fires

Class D fires are dangerous because metals burn intensely. Find out more about Class  D fires and how to put them out below.

What is a Class D Fire?

Class D fires involve combustible metals like magnesium, aluminum, lithium, sodium, and potassium. They differ from regular fires because the metals involved can react in dangerous ways. They can burn at extremely high temperatures, explode, or even react violently with water or air. Plus, metal fires usually happen in industrial settings like factories, foundries, welding shops, or recycling centers. They’re often caused by metal shavings, dust, or molten metal. 

Class D fires are dangerous because they’re harder to control. They don’t behave like normal fires, so using the wrong firefighting method—like water—can make things worse. These fires can also cause serious injuries and financial damage, especially in workplaces that rely on metal processing. Find out more about Class D fires here. 

What Is a Class D Fire Extinguisher?

A Class D fire extinguisher is specially made to put out metal fires, which burn at extremely high temperatures. These metals include lithium, magnesium, aluminum, and sodium, among others. Unlike regular fire extinguishers, Class D fire extinguishers use dry powder to smother the fire. They also prevent dangerous reactions between the burning metal and oxygen.

The powder inside is usually a mix of substances like sodium chloride or graphite. When sprayed on a metal fire, the powder forms a barrier that prevents oxygen from fueling the fire. It’s important to note that these extinguishers are only effective on metal fires and shouldn’t be used on other fire types.

Class D fire extinguishers are marked with a yellow star symbol and a "D" inside, so you can easily identify them. If you work in environments with combustible metals, having them is a must. Find out more about Class D fire extinguishers here. 

How to Put Out a Class D Fire

Here’s how to put out a Class D fire:

1. Stay Calm

Don’t panic. Take a deep breath and assess the situation. If the fire is small and manageable, you can try putting it out. If it’s spreading fast, evacuate and call the authorities.

2. Identify the Metal

Find out which metal is burning if possible. Magnesium, sodium, and other reactive metals act differently in a fire. Knowing the type helps you use the right tools.

3. Use the Right Tools

You can use a fire blanket or fire spray if the fire is small. To do this, simply cover the fire with the blanket or aim the spray at the base of the fire and sweep side to side. For medium fires, use a Class D fire extinguisher. Stand about 10 feet away and follow the PASS (Pull, Aim, Squeeze, Sweep) method. 

4. Never Use Water

Don’t pour water on a Class D fire.  It can make things worse, especially with reactive metals like sodium.

5. Monitor for Reignition

Closely watch the area even after the fire goes out. Class D fires can reignite, so stay alert and ready.

6. Evacuate if Needed

If the fire gets too big or you don’t have the right tools, evacuate right away. Call the fire department once you’re safe.

How to Put Out Class K Fires

Class K fires are dangerous because they involve oils or fats that get hot quickly. Water also makes the situation worse by splattering the oil and spreading the flames. Find out more about Class K fires and how to put them out below. 

What is a Class K Fire?

Class K fires are also known as grease fires. They happen when cooking oils, fats, or grease catch fire. These fires are common in kitchens—both at home and in restaurants or food trucks. The fire starts when the oil gets too hot and ignites, often due to unattended cooking or overheating.

Class K fires are dangerous because they spread quickly and can cause serious injuries. You should never use water to put out a grease fire because it makes it worse. Instead, you should use a fire blanket, fire spray, or Class K fire extinguisher when a grease fire breaks out in your kitchen. Find out more about Class K fires here. 

What Is a Class K Fire Extinguisher?

A Class K fire extinguisher puts out fires caused by cooking oil, fat, or grease. They’re common in kitchens, especially when deep frying.

Class K extinguishers work by spraying a fine mist of chemicals that react with the burning oil. This creates a soapy layer on top of the fire. It then cools down and stops the fire from reigniting. The chemicals are usually potassium-based, and they’re effective even when the fire involves appliances like stoves or ovens.

In addition, Class K fire extinguishers are marked with a black hexagon with a “K" in it. If you're cooking with oil or fat, it’s a good idea to have them nearby. Find out more about Class K fire extinguishers here.  

How to Put Out a Class K Fire

Here’s how to put out a Class K fire:

1. Stay Calm

Take a deep breath. Panicking won’t help. Is the fire small? Do you feel confident about handling it? If yes, keep going. If not, evacuate and call the fire department.

2. Turn Off the Heat Source

Turn off the heat source if it’s safe. Doing this helps stop the fire from getting worse.

3. Use the Right Tools

Contrary to popular belief, fire blankets work on grease fires. Simply cover the fire with the tool, especially if it’s in a pot or pan. Doing this cuts off oxygen and puts out the fire. If you don’t have a blanket, use a fire spray. Aim at the base of the fire and spray side to side until the flames go out. You can also use a Class K fire extinguisher if you prefer it. 

4. Don’t Use Water

Never pour water on a grease fire. It can splatter the oil, spread the flames, and cause an explosion.

5. Evacuate If Needed

Leave your house if the fire is too big or out of control. Follow the RACE protocol if possible. Once you’re safe, call the fire authorities immediately. 

How to Put Out Stove Fires

Stoves use high heat, which can ignite flammable items like paper towels, dishcloths, and grease. Here’s a simple guide on how to put out a stove fire: 

1. Turn Off the Heat

Turn off the heat first. Doing this prevents the fire from getting worse. If you have enough time, put on fire protection gloves to avoid injuries.

2. Don’t Move the Pot or Pan

Avoid moving the pan or pot. If you do, you might spill hot oil and make the fire worse.

3. Use a Fire Blanket or Fire Spray

The best tools for a stove fire are fire blankets and sprays. Extra large fire blankets smother the fire by cutting off the oxygen. Meanwhile, fire sprays work by cooling down the fire. Both are safer than fire extinguishers because they don’t leave toxic residue in your kitchen. 

4. Let It Cool Down

If you’re using a fire blanket, leave it on until everything cools down. Watch out for hot spots that can reignite as well. 

5. Use a Fire Extinguisher as a Last Resort

If all else fails, grab a kitchen fire extinguisher. We recommend using it only if you’ve exhausted the tools above. Fire extinguishers leave toxic residue, which is bad for the place where you prepare food.

How to Put Out Pit Fires

Fire pits can be dangerous because they involve open flames, which can easily spread to nearby things like grass, leaves, and wood. Fire pits can also cause burns or permanent injuries. Here’s how to put out a fire pit safely:

1. Stop Adding Fuel

First, stop adding any more fuel to the fire. Fuel sustains the fire, so removing it from the equation helps put it out faster. 

2. Use Water

Spray water on the flames if you have a hose. Keep a safe distance to avoid burns. Then, stir the contents with a shovel or stick to make sure everything gets wet.

3. Use Sand or Dirt

If you don't have water, scoop sand or dirt and pour it into the fire pit. Then, stir it into the ashes and embers to fully put out the fire.

4. Use a Fire Spray or Extinguisher

You can also use a fire spray or fire extinguisher. Just aim at the base of the fire and spray back and forth until the flames die. 

5. Use a Snuffer

If you have a snuffer, place it on top of the fire pit to cut off the oxygen and put out the fire. Let it sit for about 30 minutes to completely extinguish the fire. 

6. Let the Fire Die Naturally

You can also let the fire burn out on its own. But make sure it’s completely out before leaving. You should also keep an eye out for hot spots that might reignite.

How to Put Out Oven Fires

High temperatures inside your oven can make the fire grow quickly, especially if there are flammable items like grease, food debris, or oven mitts nearby. Here’s how to put out oven fires properly:

1. Don’t Open the Oven

Fire needs oxygen to grow, and opening the door could make it worse. Keep the door closed and let the fire burn out if possible.

2. Turn Everything Off

Switch off the oven and any nearby appliances to prevent the fire from spreading.

3. Use the Right Tools

Don’t use water. Oven fires are usually caused by grease, and water can make it worse. Use a fire extinguisher or fire spray designed for grease fires instead. 

4. Open the Windows

Open the windows once the fire is under control or if it burns out on its own. Doing this helps clear out the smoke. 

5. Call 911 

If the fire doesn't go out or the flames are too big, evacuate immediately. Then, call the fire department and stay outside until help arrives.

How to Put Out Chimney Fires

Knowing how to put out chimney fires helps keep you and your loved ones safe. Plus, they can quickly spread to other parts of your house.  If not extinguished properly, these fires can damage the chimney structure, weaken the roof, and more. Here’s how to put out chimney fires:

1. Call the Fire Department

It’s almost impossible to put out a chimney fire on your own. So, call the fire department first. They can handle things from there.

2. Try to Put Out the Fire

If it’s just a small flare-up and you feel safe, use a fire extinguisher, toss some sand, or pour water on the fire.

3. Close Vents and Dampers

Close all the vents and dampers if you have a stove chimney. Doing this cuts off oxygen and helps slow down the fire.

4. Get Everyone Out

Get everyone out of the house if the fire is getting bigger and spreading quickly. Don’t waste time grabbing your belongings. Get outside and stay there until the authorities arrive. 

5. Don’t Go Back Inside

Once you're out, stay out. You might be tempted to check things, but don’t. Remember, chimney fires can escalate fast. Always prioritize your safety, and don’t re-enter your house for any reason. 

How to Put Out Garage Fires

According to the US Fire Administration, garages have more fire risks than other areas of the house. They’re also filled with fire hazards such as gasoline, electrical tools, and wood. Here’s how to put out garage fires:

1. Identify the Type of Fire

Figure out what caused the fire. Is it wood, grease, chemicals, or an electrical tool? Knowing this helps you pick the right tools to put it out. 

2. Don’t Use Water on Electrical Fires

Pouring water on an electrical fire can electrocute you. Avoid using water unless you’ve cut the power first.

3. Use the Right Tool

Grab the appropriate fire prevention tool. Use a fire blanket or Class C fire extinguisher to put out electrical fires. On the other hand, use a Class B fire extinguisher if the fire is caused by a flammable liquid or gas. 

4. Evacuate if Needed

Get out of your house if the fire keeps growing or if you feel unsafe. Stick to your fire evacuation plan and help those who have difficulty moving. 

5. Call the Authorities

Call the fire department once you’re safe. They’re trained to handle fires, so let them take over.

Fire Extinguisher Alternatives

While fire extinguishers help a lot, they can be expensive, heavy, and hard to store. They might also contain toxic chemicals and leave a mess that’s hard to clean up. 

A fire spray is an easy-to-use, lightweight, and affordable alternative to Class A fire extinguishers. Prepared Hero’s fire spray is also biodegradable and non-toxic. Unlike a fire extinguisher, you can safely use it around your family and pets. 

Here’s a table summarizing the differences between Prepared Hero’s fire spray and a regular fire extinguisher:

Another alternative is a fire blanket, which depletes the fire’s oxygen supply. By doing this, it puts out small Class A fires in seconds. It also doesn’t leave a mess because it simply covers the fire.

Unlike fire extinguishers, Prepared Hero’s fire blanket doesn’t expire. You can reuse it as many times as you want as long as it’s not damaged. Plus, you can use it to save someone on fire. 

Here’s a table summarizing the differences between Prepared Hero’s fire blanket and a regular fire extinguisher:
