Will a Fire Extinguisher Ruin an Oven?

Typically, using a fire extinguisher won’t ruin your oven. However, you have to make sure you are using a fire extinguisher that is rated for home use and will put out the fire and not make it worse. When you are dealing with grease or oil, you have to remember that those types of fires respond differently than a combustible item would such as paper or cloth.

You are also going to want to make sure you are cleaning up any residue that has been left behind from the fire extinguisher as soon as you have the fire contained, and the oven has cooled. If you wait, you could ruin your oven.

Remember, if you are using a standard fire extinguisher versus a carbon dioxide fire extinguisher, it will leave a chemical residue on anything you have sprayed the fire extinguisher on. You will want to make sure you are cleaning that up properly and taking safety precautions while doing so.  

How to Put out an Oven Fire

If you are using your oven and a fire starts, the first thing you are going to want to do is to turn off the oven and keep the door closed! Most of the time, just by doing that, the fire will die down and ultimately go out. When you cut a fire off from any oxygen, it will kill the fire.

If that doesn’t work and you need to break out the fire extinguisher, make sure you follow the PASS technique. The Occupational Safety and Health AdministrationOpens in a new tab. (OSHA) breaks down the PASS technique with fool-proof directions to use the fire extinguisher correctly.

Grab your fire extinguisher, and follow these steps to put out the fire:

  • P – Pull out the safety pin from the fire extinguisher 
  • A – Aim the extinguisher low toward the base of the fire 
  • S – Squeeze the handle
  • S – Sweep the spray from side to side spraying all over the fire

Cleaning up After an Oven Fire

After you have successfully put out the fire in your oven, you are going to want to clean up any mess left behind. Make sure you clean up as soon as your oven has cooled enough to start cleaning, or corrosion of your appliance could occur. According to Round Rock Appliance RepairOpens in a new tab., there are steps you need to take to clean your oven after a fire properly.

Five steps for cleaning your oven after a fire:

  • The first thing you are going to want to do before you even start cleaning is to put a mask over your face and wear plastic or rubber gloves. You are cleaning up chemicals, so you want to take precautions. Chemicals can cause irritations to your skin, and you don’t want to breathe them in while cleaning, either.
  • Grab your vacuum with a hose attachment. You are going to want to use your vacuum to suck up any debris inside your oven before you start cleaning.
  • If there are spots that you couldn’t reach with your vacuum, grab your dustpan and brush and remove the rest of the debris or dry powder from those tight spots.
  • Take a sponge and wet it. You will then take the wet sponge and wipe down your oven completely. You will need to rinse your sponge several times while you are doing this step. Doing this, you should be able to remove most of the mess from using the fire extinguisher.
  • Use an oven cleanerOpens in a new tab. inside of your oven. Follow all instructions on the cleaner. Using an oven cleaner will remove any leftover debris and allow your oven to be ready to use again. Do not use the self-cleaning function on your oven if your oven has that option.

If the fire has destroyed your oven to the point where you don’t feel comfortable using it, you may need to replace your appliance.
