One night back in 1972, our company’s founders were attending a neighborhood block party when they overheard someone talking about a recent grease fire. The neighbor stated, “I got distracted and left the stove on. Sure, I had a fire extinguisher and baking soda in the fridge. But since I wasn’t in the kitchen to use them, neither did me any good!”  Hearing this story became a revelation, and launched the design of the simple, automatic fire suppressor that is today known as StoveTop FireStop.

Providing simple, automatic cooking fire suppression to people is something we take very seriously. StoveTop FireStop has protected individuals and families from the deadly effects of cooking fires since 1972, and we want to do the same for you and your family.

Originally founded in 1963 by Bob and Della Williams, the company now known as WilliamsRDM has a knack for solving complex problems with simple solutions.

  • “StoveTop FireStop Automatic Fire Extinguisher is a unique device and I was amazed at its simplicity. I am personally glad to see such an item available to all homes and businesses where range hoods are used. It is easy to see why you are excited about this amazing product and I recommend it for all home use. StoveTop FireStop should become as common as the smoke detector.”

  • “…Call came in from complainant reporting that her stove was on fire. Responded within a few seconds and found smoke detectors in building sounding and smoke in apartment…. The complainant had run outside…I entered the unit with a [hand-held] extinguisher and saw lingering smoke from the stove, which was still turned on…. It was apparent that a StoveTop FireStop automatic fire extinguisher had opened up and put out the flames on the rear left burner.”

  • “I am a fire inspector in Grand Rapids, Michigan. In 2009, I did some research on your product with a apartment complex owner who had suffered losses from both fire and fires extinguished by his buildings’ automatic sprinkler system. During this time, though I was directed by my supervisor to refrain from endorsing an unlisted product, I was supportive of their (your product’s) use.

    I have recently been informed that one of your Venthood canisters extinguished a grease fire at that very apartment complex. Extinguished so well if fact, that there was no fire department response.

    My recent promotion to Chief Fire Inspector allows me to be a vocal proponent of your product. That incident, allows me to be very vocal. If I can be of any assistance, please let me know. The apartment complex in question is located in the City if Grand Rapids, Michigan. Bayberry Pointe Apartments (616) 791-1948.”

  • “We recently completed an implementation the Venthood version of StoveTop Firestop across one of our large and geographically diverse insured’s with remarkable results. The average kitchen fire claim plummeted from $33k to less than $5k. Also key to our success was the role that Tri-Core played with co-marketing, distribution and other logistics. For us, this product has saved units and lives.”

  • “In the fall of 2011, Federal Management made the decision to install fire suppression canisters in hood vents of all apartment units at Riverside Village. Although it was a costly undertaking, we felt that the possible prevention of fire caused by stove outweighed the initial cost.

    Over the weekend, a resident of our community was able to avoid a potentially dangerous grease fire on her stove when the suppression canisters extinguished the flames. We are grateful that no one was injured and the apartment suffered only minor damages.

    If you ever have questions from property managers or owners as to if they are worth the price of installation, please feel free to pass on my information for referral.”

Has StoveTop FireStop saved your Property
from Fire Damage?



How do I keep my StoveTop FireStop working?

A: StoveTop FireStop products require neither maintenance, inspections, nor repairs during their six year effective life. In the event of grease build-up, gently wipe off accumulated grease using a damp cloth. Be sure that no liquids come in contact with the fuse or the label.

What if StoveTop FireStop activates while I’m cooking?

A: StoveTop FireStop will only activate when the fuse comes in direct, sustained contact with a flame. You do not have to worry about false activations from typical cooking heat, steam, or smoke.

I’ve never heard of StoveTop FireStop. Is it a proven product?

A: Yes, in fact, StoveTop FireStop, is North America’s leading automatic indoor residential fire suppressor. Since 1972, StoveTop FireStop has successfully suppressed cooktop grease fires. Additionally, StoveTop FireStop has been independently tested, and is recommended by fire departments, property owners, and insurance providers across the United States, Canada, and the UK.

I’m concerned about the appearance of StoveTop FireStop over my stove; won’t it look funny?

A: The design of a traditional vent hood will usually hide (from across a room) properly installed StoveTop FireStop units. The StoveTop FireStop Microhood will be visible underneath the microwave. Because of this, we offer the Microhood in white and black so it will blend in with typical kitchen appliance color schemes. We also have a line of decorative covers available through our distributors or online here.

I already have a sprinkler system; why would I want StoveTop FireStop?

A: The StoveTop FireStop is an important supplement to sprinklers, which also effectively suppress fires, but may cause significant water damage when discharged. StoveTop FireStop can suppress a stovetop fire before it spreads and before it triggers the sprinklers, preventing larger fires and the collateral damage of sprinkler systems.

What if our vent hood is non-magnetic?

A: If magnets will not adhere to the venthood unit above the stovetop, but the distance between the stovetop and vent hood is within the specified range of 27-35 inches, order our alternative-fastener mounting kit here.

What if the Microhood covers the stove light when mounted?

A: To work correctly, StoveTop FireStop Microhood should be mounted over the front and back burners of a typical 4-burner stove. In a few microwave models, this places the unit directly under the lighting kit. This does not change the effectiveness of the Microhood and will not burn the plastic, but it may cause a slight melting or warping of the plastic if the light is left on for a long time. Therefore, if your stove light will be obstructed by the unit, please remove the light bulbs before completing the StoveTop FireStop Microhood installation.

Can I use StoveTop FireStop with a gas stove?

A: StoveTop FireStop has been successfully tested on electric and gas stovetops and can also be used on induction as well as ceramic / glass-top ranges. StoveTop FireStop products must be installed and used as described in our installation instructions for maximum effectiveness.

Our products are non-pressurized and are designed to release (sift) dry powder onto the fire via gravity. In most unattended cooking fires, the pan or skillet that catches fire is covering the burner, or heat source, below it. Thus, StoveTop FireStop’s fire-suppressing powder only falls into the pan and the exposed surface areas of the stove. The pan itself typically prevents the powder from directly reaching and extinguishing the burner. Since every fire is unique, it could be possible that under certain circumstances, a gas burner could be extinguished by our product. We have sold millions of StoveTop FireStop units over the years and have not had any customers bring such an example to our attention.

It should be noted that our products do not shut off the stove. StoveTop FireStop makes a loud “pop” noise which alerts the occupant that our product has activated. Regardless of the type of stovetop, we suggest that the occupant turn off the stove, if it is safe to do so, after our device has deployed to prevent the fire from re-igniting.

How do I know whether my StoveTop FireStop units have exceeded their effective life?

A: StoveTop FireStop units have a six year effective life In order to ensure that our products are as effective as possible in suppressing cooking fires, we do not support the use of StoveTop FireStop products beyond their stated six-year effective life. If your units have exceeded the “replace before” date, it is important that you remove and/or replace the existing units now.

Why does my StoveTop FireStop have a 6 year effective life?

A: Based on the the research we conducted during the development of our STFS Plus product and on some proprietary changes to our fire suppressant powder, we now certify the effective life of all new StoveTop FireStop products one additional year (6 years from manufacturing date).

Does StoveTop FireStop have a return/refund policy?

Yes. Please click on the link to our STFS Return Policy for more details.

Will this product work for other applications such as putting out chimney fires, Christmas tree fires, or automobile engine fires?

A: No. StoveTop FireStop is strictly designed and tested for indoor residential stovetop grease fires only.

Is StoveTop FireStop UL Listed?

A: The short answer is, “No, we don’t have our UL certification yet, but it’s not from a lack of trying. And that doesn’t mean we’ve failed any tests; UL simply hasn’t been able to find a Standard to test StoveTop FireStop to!” The bottom line is: our product is unique. So unique, in fact, that no matter how much the engineers at UL like it (and they do really like it!), they simply don’t have a standard on the books that StoveTop FireStop fits into. It’s not a traditional, portable fire extinguisher. It’s not a liquid based, pressurized commercial system. It’s not a Halon or other synthetic “dry liquid” system. At the end of the day, our product conforms to “elements of UL 300A, 199, 711 and 1254,” but none of them completely. We’ve been selling StoveTop FireStop to both the US Government and its many agencies and to the private sector (all across the U.S., Japan and Canada) since 1972. We have confidence that eventually we’ll get this resolved, but for now, we will just have to refer you to the attached document and keep our fingers crossed on UL.
