STOP-FYRE® Fire Extinguisher FAQ

Here are some of the most frequently asked questions about STOP-FYRE® fire extinguishers

STOP-FYRE® is a proprietary blend of liquefied fire suppression gases, which is a trade secret.
It is our own formula and a trade secret.

You need three things to have a fire – heat, oxygen, and a fuel source. A traditional powder extinguisher simply tries to smother the fire. STOP-FYRE® will cool it, displace the oxygen, interrupt the chemical reaction, and unless a big gust of wind comes along, it will stay at the heat source preventing re-ignition.
About 12 seconds if expelled all at once, but STOP-FYRE® should be used in short bursts.
We have customers who have units they purchased from us over 20 years ago which are still in working condition, and these units have never been serviced. We also put a No-Hassle Lifetime Guarantee on it, so if it ever leaks or breaks, we replace it. End of story.
Yes. STOP-FYRE® is a multi-shot fire extinguisher and can be used multiple times on different fires. However, AKE recommends that you refill your unit after each use because you never know how big your next fire will be.
No. STOP-FYRE® is safe on machinery, electronics, and skin.
Our Standard STOP-FYRE® is 3” in diameter, 11” tall, and has a 6” handle width.
They love it. It’s a very specific tool in their toolbox for putting out fires for when they are hidden and hard to reach. Fire departments have used STOP-FYRE® to save homes, cars, and machinery. Plus they don’t have to maintain it, worry about it, and fuss about it. See for yourself what they think.
AKE started in 1989. We have been making and selling fire extinguishers for over two decades. We’ve got tens of thousands of units that are still on farms and in homes that are in just of good of condition today as when they were bought. Our history and experience shows that we will remain in business for years to come.
You can refill your STOP-FYRE® unit for a reduced price. Please see our Get A Refill Page for details.
Price is what you pay today for your purchase. Cost is what you pay over the lifetime of owning your purchase. When compared to a traditional fire extinguisher, STOP-FYRE® has a higher price, but a lower cost. In fact, after just a little over 3 years, STOP-FYRE® is less expensive to own than dry chemical. And without all of the hassles of a traditional fire extinguisher, our customers tell us they simply wouldn’t own anything but STOP-FYRE®.
STOP-FYRE® will extinguish A, B, and C fires. Class A fires are common combustibles which leave behind an ash (e.g. wood, paper, rubbish). Class B fires are flammable liquids and gases. Class C fires are electrical. A, B, and C are the typical fires you’d encounter in your normal day-to-day farm, home, and other business operations.
Yes. We strive to anticipate whatever you might be challenged with as a customer and help you with that before you even encounter the difficulty.
Not difficult at all – twist, pull the pin out, and then fight the fire.
Our Standard STOP-FYRE® is perfect. However, just to be safe, we recommend two units for larger applications and machinery, like combines.
The only difference is that our Premium STOP-FYRE® has a gauge to satisfy inspections.
We sought to create an extinguisher that could be used in a pig barn or any other highly corrosive environment. They are made out of a very thick aluminum alloy with a special paint that won’t corrode.
The gauge measures whether there is pressure inside the canister or not. It’s important to have a gauge on a powder unit because the extinguisher would weigh the same whether it had pressure or not. However, if our extinguisher leaked, it would feel like an empty aluminum can. If there was any sort of a leak in a STOP-FYRE® extinguisher (think of a balloon with a pinhole in it), the whole canister would empty out. We put a gauge on our Premium STOP-FYRE® to satisfy an inspector who may be unfamiliar with our clean agent extinguisher.
We call it a boot. It’s there to protect the gauge from damage.
Yes, unless Fire Code requires you to keep a larger dry chemical powder unit. In that case, keep your dry chemical units to satisfy an inspection, but USE your STOP-FYRE® units when you actually have a fire. STOP-FYRE® will save you money and help you avoid the hassle from a dry chemical powder cleanup.
No fire extinguisher fumes/dust are “safe” to breathe in directly – they are made to extinguish a fire after all. You also don’t want to breathe in directly the smoke or fumes from a burning fire. Ultimately, you want your extinguisher to work instantaneously and then ventilate the area immediately. Do not use STOP-FYRE® in confined spaces less than 150 cubic feet, which is about 5 feet by 3 feet by 10 feet. Visit our See STOP-FYRE® Work Page to see how quickly STOP-FYRE® works in all kinds of circumstances.
STOP-FYRE® is a liquefied gas. It exits the extinguisher as a liquid vapor mixture and then turns back into its natural state – a gas. See for yourself how it is safe on skin, safe on electronics, and safe in a kitchen.

STOP-FYRE® won’t freeze, but according to Boyle’s Law temperature affects pressure and volume. When the temperature is lower, pressure will be lower and a more condensed volume of STOP-FYRE® will spray out. This means, in extremely cold conditions, it will take more agent to do the same job than it would normally. Likewise, in an extremely hot situation, STOP-FYRE® will spray out in more of a vapor because the pressure will be greater and the volume will be less. For best results, store STOP-FYRE® above freezing even though its effective range of use is -40 to +120 degrees. Dry chemical extinguishers and ALL pressurized canisters are affected the same way by temperature extremes, BUT other companies typically won’t tell you this fact.
No. Temperature has no long-term negative effects upon the extinguisher. See the FAQ “Will STOP-FYRE® freeze?” to understand more about short-term temperature effects. We make them in Minnesota and have thousands of customers in very cold climates that love STOP-FYRE® in part because of its range of use and durability.
The most standard fire extinguisher available today is a dry chemical powder extinguisher. It contains ammonium phosphate, which is the only multi-class powder which means it will work on A, B, and C fires.

STOP-FYRE® is in the liquefied gas extinguisher category, which is also effective on A, B, and C fires. Sodium bicarbonate powder extinguishers are typically the white ones that you see at Walmart and they are only effective on B and C class fires.In some rare cases you can find an old Halon extinguisher. These are no longer made so be cautious about buying them online unless you trust the seller because the agent may have already been used and the extinguisher refilled with something else but the label still states “Halon”.

Typical foam fire extinguishers extinguish class A fires. You can find some varieties that work on B and C fires, but the main ingredient in a foam fire extinguisher is water, so it is not advised to use them on electrical fires. CO2 fire extinguishers are very ineffective on Class A, but decent for B and C. You don’t find those very often because they are usually really heavy and awkward. Another reason you don’t find them is because of the concern over their safety. Because carbon dioxide will not liquefy no matter how much pressure is used, the operating pressure is 600 psi or more, which is quite high.

Also, the effective range is only about three feet away from the fire. Oftentimes you’ll get an electric shock, believe it or not, when you use CO2 fire extinguishers believed to be caused from buildup of static electricity. Water fire extinguishers are simply pressurized water and only effective on Class A fires. You must add antifreeze to them in cold climates because otherwise they can freeze in the wintertime and break from the water expanding during freezing.

If your insurance company offers a discount for having a fire extinguisher, you’ll get the same discount for STOP-FYRE® as you will for any other fire extinguisher. However, most insurance companies will pay for the refill of your STOP-FYRE®.
