TECO® FireBag® Thermal Activated Fire Safety Shutoffs
Natural gas is delivered to customers at high pressure, making the gas service regulator a critical safety component in the delivery network. This device safeguards customers and their premises by controlling the immense energy that could flow through the service. However, these regulators installed above ground are highly vulnerable to numerous hazards, especially fire. Constructed primarily of aluminum, plastic, and rubber, gas regulators and meters fail under the heat of a fire. When they fail, they release high pressure gas, fueling dangerous fires. The Fire Solutions Group LLC recently conducted live testing of gas meter sets in simulated structure fire conditions at the York County Fire Academy in Pennsylvania. The results were telling. In every test, the regulator and meter failed, releasing high volumes of gas at significant velocity.
As shown, these gas fed fires are powerful and highly dangerous for responders. The shutoff valve often located at the gas riser near the meter, becomes inaccessible during a fire. Consequently, the fire continues to burn until the utility company intervenes, which could take well over an hour. The solution: the Teco FireBag Thermally activated Shutoffs – TAS. FireBag Thermally activated shutoffs are essential safety devices used globally in fuel systems. Designed to automatically close during high temperature events, the thermally activated shutoff device prevents gas from venting into fires by shutting off the supply before regulator failure occurs.
Installed upstream of the gas regulator, the FireBag thermally activated shutoff provides a reliable means to protect property and public safety, while creating a safer environment for emergency personnel to manage fires and evacuations. The FireBag thermally activated shutoff device utilizes a fusible metal alloy, spring, and plug mechanism. When exposed to fire, the fusible alloy triggers the plug forming a gas-tight seal. This simple, maintenance-free solution requires no power, actuators, or external heat detectors, relying solely on heat exposure to activate. Once triggered, the FireBag TAS remains closed, requiring replacement before the gas supply can resume. FireBag thermally activated shutoffs are suitable for both indoor and outdoor installations, whether for single or multiple meter setups. It is most effective when installed upstream of the regulator or indoors just inside the building wall, protecting regulators and meter sets. The simple installation of a FireBag can prevent costly hazardous situations. While we cannot control when a fire might occur, we can control its impact. A FireBag thermally activated shutoff device ensures that escaping gas does not intensify the fire.
Silver Springs, MD: Large, high-pressure gas fed the fire, halting rescue efforts for one hour – the time it took for the gas company to respond and shut off gas system.
Speaker 1: Breaking news, a massive fire in Maryland, taking down an apartment complex. Firefighters rushing to save survivors. More than two dozen people taken to the hospital.
Speaker 2: The fire was enormous and the heat was so intense. I was probably about, I’d say a 100 to 150 feet away, and you could just feel the heat. It was almost like you were standing in front of an oven with the door open.
Speaker 3: At that time, the firefighters and the medics had their hands full fighting the fire and getting everyone away from the scene – doing that part of their job. So I could see up and down his leg. He had second degree burns. It’s tough to treat burns, so I just did what I could for him.
Speaker 4: You know, for that situation had to be very desperate in order for a parent to drop their child out of a burning building.
Speaker 5: Yeah. Do you mind hanging onto this kid so I can get my car over here?
Speaker 6: I got it. And then I could put him in some cool.
Speaker 7: I think because of the complexity of it and the scale, scope, and size of what we were looking at, it was just basically muscle memory, to be honest with you. Just getting these people out of this hazardous environment and getting them safe, and then ensuring that there’s not other people that, or in there as well.
CA Congressperson Laura Friedman Testimony on CA Wildfires
Florida Congressman Daniel Webster, Chairman of House Transportation and Infrastructure Subcommittee On Railroads, Pipelines, And Hazardous Materials
Ms. Freeman, you’re recognized.
CA Congressperson Laura Friedman:
Thank you, chair Webster and ranking member Titus, and for the witnesses for coming here today. Unfortunately, California is no stranger to natural gas transmission pipeline disasters. Fifteen years ago, of course, we had the explosion in the San Bruno neighborhood in Northern California where several people were killed, and 47 million standard cubic feet of natural gas was released. I believe eight people were killed, and about 38 homes were destroyed, and we all still grieve for them in California.
And closer to home for me in Los Angeles, thousands of people are still suffering health impacts because of the leak at CIO Canyon. So the question is, are we now safer since San Bruno and have we put into place everything we need to keep our community safe? And I believe the answer is no, because the last two years have been the deadliest two year period for pipeline since the San Bruno explosion. In the past two years alone,
Thirty people have tragically lost their lives due to pipeline safety incidents. I hope to work with the subcommittee – with everyone on the subcommittee – to develop robust standards to prevent these disasters from occurring. Now, LA has a high number of liquid and natural gas pipelines through very densely populated areas, including in my district in Glendale and Burbank, Los Angeles, and Pasadena. During the LA fires, we saw a lot of ignitions happening at the homes that were impacted by fire because the gas pipelines, the natural gas in the homes was on fire. Now, I toured the Eaton Canyon area one and two and three days after the fire, and those plumes of natural gas flames came up from thousands and thousands of homes. In fact, there were victims walking around their former homes looking to collect their personal items, trying to navigate around seven, eight-foot tall walls of flame in their houses because those natural gas pipelines were still on and they were still on fire.
And I saw ignitions two days later happening because of winds pushing those flames around. So my question for Mr. Taylor is what did your members, what steps did they take during those fires to minimize that kind of incident? And why were those, should those have still been, those ignitions still been happening two, three days after the fire? How do we make sure that we don’t have the public walking through these burn areas through their homes while they have to navigate around very intense flame plumes. I don’t even know what to call them – coming out of their former homes.
OH Congressman David J. Taylor:
Yeah, so thank you, Congressman Congresswoman. The, that specific type of fire and that specific type of instance would be tied more towards the distribution system. And so again, from a transmission side, we could potentially isolate, don’t know the specific details of all the situation there and how that gas is being fed to that exact location and the areas you’re speaking of. But that would be more of a distribution type focus, distribution type question on how they could potentially isolate those areas.
CA Congressperson Laura Friedman:
And just so that you have it in your head, we’re talking thousands of homes an entire more than one neighborhood, so not just one house at a time, but you had entire neighborhoods that were impacted by this. Mr. Taylor, as you know better than me, fire valves are inexpensive spring-loaded valves that are designed to melt before the pipeline fails, sealing the pipeline and preventing natural gas from fueling fires in these kinds of incidents. Why is it important to install fire valves in gas distribution pipelines, especially for communities like we have in Los Angeles that are fire prone and earthquake prone? Just disaster prone in general?
OH Congreeman David J. Taylor:
I don’t know if you’re asking me or Mr. Caram, but whoever.
CA Congressperson Laura Friedman:
Yeah. So again, from our standpoint, that would be more distribution focused. We wouldn’t have that type of application for transmission pipelines, but it would make sense for distribution. I’ll let Mr. Karen answer the question though as well.
Chairman Webster:
Yeah. Thank you for that question. And I’m so sorry about the devastation in your district and around your state. And yes, what you’re talking about is on the distribution systems, which are the service lines that go into each home and building. And you can install these fire valves on service lines very easily, and they have a low melting point polymer that holds the valve open. And when they’re exposed to heat, that polymer melts and the valve automatically closes because we see in times of emergency, it’s often difficult and it takes time to shut off the valves around a system, on a distribution system. And so these would, in the case of a fire, whether it be a home fire that started in the kitchen and spread, or if it’s something more widespread like a wildfire through a community, these could mitigate the extra damage caused by the gas service to the homes.
CA Congressperson Laura Friedman:
Thank you both for your free answers. And I yield back.
Palisades Wildfire Gas Supply on Fire
Matt Gutman's account of fast-moving blazes in Palisades CA wildfire.
This is obviously a state of emergency here in Southern California. The worst winds here in over
a decade. I want you to hear something — that hissing sound just happened a few seconds ago. It’s gas, I think a pipe that is exploded in that house behind us that just burst into flame within the past 5 or 6 minutes. Hundreds of homes in Pacific Palisades, the epicenter of the worst fires, have burned, including much of the downtown area. And I want you to notice how the embers are being cast by this fire being blown down range by this — I don’t know this point, 20 – 30 mph wind and that is causing additional fires. This is completely out of control at this point. Firefighters cannot get a grip on this fire. The wind is set to persist for many hours — even until tomorrow morning, so it’s not going to get any better. We don’t know of any fatalities or injuries just yet but I just want to give you the scope. It’s absolutely apocalyptic and there’s no amount of resources that can stop this at this point. George, I know, this became very personal for you. I’ve been in the palace a you can just see that house going completely up behind us. I’ve been here many, many times. My aunt lives here and when I drove up this morning it was completely unrecognizable. I couldn’t even orient myself. She lost her house; a cousin lost his house. Driving home yesterday I encountered a fire. It’s not about me it’s about — what about 10 million people living in LA county are experiencing right now — which is that terror of not knowing where that next fire is going to erupt. And if your family is going to be in the crosshairs of this. So I did what so many people have done overnight, which is yesterday afternoon, telling my wife and kids — everybody get a go bag ready to go. We have to be ready to leave this hous at a moment’s notice. Fortunately for us we did not, but that is the kind of terror that millions of people are undergoing right now in LA county. You can just see how much worse this is getting moment by moment here.
Bill Caram, Pipeline Safety Trust's Exec. Dir., Advocates for thermal fire safety gas shutoffs
Chair Webster:
Mr. Caram, you’re recognized for five minutes.
Mr. Bill Caram:
Thank you. Good morning, Chair Webster, Ranking Member Titus, Ranking Member Larson, and members of the subcommittee. Thank you for inviting me to speak today on the vital subject of pipeline safety. My name is Bill Caram and I’m the executive director of the Pipeline Safety Trust. Pipeline Safety Trust was founded after the 1999 Olympic pipeline tragedy in Bellingham, Washington. An entirely preventable failure spilled gasoline into a beautiful salmon stream in the heart of our community, which ignited and killed three boys. The US Justice Department was so appalled at the operations of the pipeline company and the lax oversight from the federal government that they asked the courts to set aside money from the settlement to create the Pipeline Safety Trust as a national watchdog on the pipeline industry and its regulators.
I look forward to the day when I can tell you that there have been no fatalities since the last time I testified, but today is not that day. The last two years have been the deadliest two year period for pipelines in nearly 15 years, since the two-year period that included the devastating PG&E pipeline explosion in San Bruno, California, widely considered a low point for pipeline safety. I warn you that my message is largely the same as my previous opportunities to testify before the subcommittee, and that’s because the state of pipeline safety is largely the same. We continue to languish with consistent poor performance, with a significant incident almost every day and 30 people killed over the last two years.
In December, the NTSB held a board meeting to discuss the 2023 UGI Utilities pipeline failure in West Reading, Pennsylvania, that killed seven people and injured 11. The failed piece of pipeline infrastructure was made from Aldyl A plastic. PHMSA has known these Aldyl A components are prone to failure for decades.
The NTSB is also investigating an Enbridge pipeline failure that occurred in November, in South Jordan, Utah, that killed a 15-year-old child. The preliminary report finds that the failed pipeline was also Aldyl A. Atmos Energy, a large gas distribution pipeline operator in the Southeast, has had a string of deadly failures with troublingly common patterns. An NTSB investigation of a 2018 home explosion, that took the life of a 12-year-old girl while she practiced her cheerleading routine, found that the failed pipeline was part of an under-maintained system full of leaks that had led to fires in neighboring homes in the preceding days. Neighbors had complained repeatedly about the smell of gas. Atmos didn’t find any leaks they deemed to be hazardous before the home exploded. Then just last year in Jackson, Mississippi, a pipeline fueled home explosion killed the 82-year-old wife of a community pastor. An NTSB preliminary report found that the failed pipeline was part of an undermaintained system full of leaks that led to another home explosion in the following days. Neighbors had complained repeatedly about the smell of gas. Atmos didn’t find any leaks they deemed to be hazardous before the home exploded.
Again, if I’m repeating myself, it’s because operators are repeating their mistakes that kill people. While everyone on today’s panel supports the goal of zero incidents, unfortunately, we have a long way to go. I commend this subcommittee for working together on pipeline safety legislation over the last two years. The bill this subcommittee passed has some good provisions. Increasing civil penalties is a step in the right direction. When we try to chart penalties levied on operators against their quarterly earnings, we often can’t even visualize the penalty. It’s such a tiny percentage of earnings. So giving PHMSA more enforcement authority, albeit small in this case, is moving in the right direction.
Additionally, increasing authorized resources to PHMSA and state programs is another move in the right direction. Not only has the agency been chronically underfunded, but the additional miles of jurisdictional pipe, and the potential build out of carbon dioxide and hydrogen pipelines, demand an increase in resources from Congress. Thank you for answering that call. However, given the continued lack of progress on pipeline safety, we need more. There are many provisions in this bill that won’t contribute to safety progress. Additionally, there are common sense practical safety initiatives that would make a real impact on safety, such as fire shutoff valves. These devices can mitigate the damage caused by a house fire that could be made worse by the presence of gas service. The valve automatically closes when exposed to heat, preventing natural gas from adding literal fuel to the fire. These devices are inexpensive, require no ongoing maintenance, and can be easily installed on service lines.
As you discuss how to move forward on authorizing PHMSA’s pipeline safety program and make improvements to the law, I implore you to think of the empty seats at dinner tables across the country because of pipeline failures. I’ve been with families who have lost loved ones recently. I’ve been with families who lost loved ones over 25 years ago, and I can tell you the pain never goes away. Please give PHMSA the authority and the resources it needs to meet its responsibility to the American people. Thank you.
Gas Lines still blazing at homes destroyed by wildfires in the Los Angeles area.
Modesto Firefighters Risk Their Lives Fighting Gas Fed Fire
We received a call this morning at 1:01 AM for a fire in the area of 9th and J Street. Caller believed an apartment was on fire. We arrived in four minutes and found a high pressure gas line that was feeding a business in the alley between 9th and 10th off of J Street was well involved in fire and it was a gas-fed fire. Crews were able to push the fire back enough to where they were able to shut the gas off and that eliminated the fire being fed. We were able to force entry into several of the businesses and limit the extension, very minor extension into the businesses. This fire had a tremendous potential to be a very large fire in the block area. PG&E is going to have to come in, dig up the high pressure line before they can change the meter out.
We’ve still got a minor leak, and that’s obviously a big concern of ours right now.
Crew:
Truck one to check for extension on the interior of the building. They’re entering off the J Street side, which is the Alpha side.Copy J Street Alpha side of this truck.
Actually quite a bit of smoke in a restaurant off of J street.
Confirming the restaurant off of 10th Street.
Hey, firm. No fire. A lot of smoke.
Copy that. I got engine four coming to you now.
Hey, Chief, engine five. We’re on 10th of J right now.
Copy engine five. Go ahead and bring PPEs come to the command post at 9th and J.
ABC News' Coverage of Deadliest NYC Fire
Paula:
Now to that deadly four alarm fire claiming at least 12 lives here in New York, including a one-year-old child. You’re looking live over the scene right now. This was the worst fire the city has seen in 25 years, more than 170 firefighters responding to the blaze in the Bronx and ABC’s Eva Pilgrim is at the scene with the very latest on the investigation. Good morning to you, Eva.
Eva Pilgrim:
Good morning, Paula. Those fire victims forced out into this bitter cold weather. Many of them without coats, without shoes, firefighters fighting this fire this morning. They are going through the building now doing their search and recovery process. Those firefighters got here in three minutes, but for many inside, that was not fast enough.
170 firefighters rushing to battle the deadliest fire in New York City in more than 25 years.
We have a scene here in which 12 people have died and four are fighting for their lives.
Eva Pilgrim:
CPR performed as victim after victim removed on gurneys.
Based on the information we have now, this will rank as one of the worst losses of life to a fire in many, many years.
Eva Pilgrim:
The blaze began at 6:30 PM when thick black smokes swept through the five-story building. Inside these apartments, an apocalyptic scene. Parents screaming for help, children crying, so many unable to get out.
This is the worst fire tragedy we have seen in this city in at least a quarter century.
Eva Pilgrim:
The only thing not destroyed, the building’s exterior. At least three dead from the same family.
Burned. They were burned. Even little kids in the stretchers burned. It’s crazy.
Eva Pilgrim:
In one apartment, a mother found in a bathtub clutching her baby, both deceased.
I came out through the window.
You came out to the window?
Yeah, there was smoke everywhere already.
Eva Pilgrim:
This resident managed to reach the fire escape, leaving his phone and wallet, able to grab just a blanket. He was better off than many here who were forced to flee their homes with no coats or shoes. The Red Cross rushing to provide warmth to the stunned survivors.
No word this morning on the cause of this fire. One of the things investigators will be looking at is why this fire grew so quickly. They are looking now at the possibility that the fire burned into a natural gas line, fueling these flames. Dan.
Dan:
A lot of questions. Just a horrifying story, Eva. Thank you very much.
How & where TECO FireBag thermally activated gas shutoffs are installed
According to the National Fire Protection Association, U.S. municipal fire departments responded to an estimated average of 51,600 fires per year involving ignition of flammable gas as the type of material first ignited, including 20,260 fires per year in or at homes and 31,340 fires per year in or at other properties. These fires caused estimated losses of 168 civilian deaths per year, 1,029 civilian injuries per year, and $644 million per year in direct property damage. A leak or a break was a factor contributing to ignition for 22% of home structure fires starting with flammable gas and for 28% of non-home structure fires starting with flammable gas.
In addition, local fire departments respond to an average of 340 natural gas or LP gas leaks per day with no ignition. Although gas leaks are much more common than gas ignitions, they can be precursors to devastating events. To combat this growing trend of events, TECO® SRL, together with TECO® Americas, has created the FireBag®, a thermally-activated gas safety shutoff. The FireBag, when exposed to fire, will automatically trigger releasing a plug to stop the flow of gas from feeding the fire. This limits the severity and fuel load of the fire event. Significant safety improvements are achieved without the need for expensive actuators, electrical power heat detectors, or fire detectors.
In the following video, we will see how FireBag activates to stop the flow of gas. In this demonstration held in Pennsylvania, we will see the FireBag in action as it closes, stopping the flow of gas and resulting fire. The FireBag thermal activated shutoff consists of a zinc-plated steel fitting containing a fusible metal alloy and spring, which, when exposed to fire, releases a plug producing a metal-to-metal seat, creating a tight seal. The fusible alloys are a reliable technology also used in many fire sprinklers. Manufactured to DIN 3586 standards, the FireBag can withstand 1,697 degrees Fahrenheit for 60 minutes, allowing time for first responders to reach the dwelling and turn the gas supply off from the curb.
Since the FireBag is a passive device and only triggers in a fire situation, it is maintenance free and requires no regular inspections. No fire or heat detectors are required to automatically intercept the gas flow. After activation, the FireBag is replaced and the gas flow can then be turned back on. The FireBag can be installed at various locations upstream of the gas meter and designed for use on indoor or outdoor, single meter and multimeter installations, with pressure ratings ranging from inches water column to 150 PSIG.
FireBags come in various sizes, ranging from three-quarter inch to two inches. If you listen closely, you can hear the activation of the FireBag and see the fire extinguish as the fuel source has been shut off. With the FireBag installed, a reliable method to protect property and the public from flammable gas fires is achieved. A safer environment to extinguish the fire is obtained for emergency personnel, and natural gas utilities and propane companies now can provide evidence of a positive gas shutoff when fire occurs, fulfilling an obligation to the public to demonstrate best efforts in creating a safe method for the delivery of flammable gas.
That is why in Europe, thermal gas shutoff devices have been required in homes since the ’90s. The FireBag currently protects millions of homes worldwide and over 100,000 in North America alone. For more information or to purchase the FireBag, please contact TECO Americas at 908-488-0909, by email at inquiry@tecoamericas.com, or visit tecoamericas.com.

The FireBag has been protecting life, property and first responders worldwide, with over 10 million installations and over 100,000 installations in the U.S.
Introducing the FireBag from Teco Americas. The simple design of the Teco FireBag thermally-activated gas shutoff valve allows it to be installed easily in line in any natural gas or propane line. Gas flows through the FireBag during normal operation. When the temperature limit is reached, the FireBag triggers and closes, immediately stopping the flow of gas. Once triggered, the fire bag will remain closed and must be replaced. For ease of installation on existing meter applications, there is a meter bar kit that includes the FireBag itself to attach to the meter inlet, and a companion coupling that goes on the meter outlet. The meter is then simply reattached to the meter bar as it was before.
For installation on a single meter, there are three different options to choose from. On the service riser, upstream of the meter bar, or using the meter bar kit. For installation on a manifold with multiple meters, there are also three different options, on the inlet of the manifold or used as a coupling between manifolds, inline on the individual taps to each meter, or using a meter bar kit on each meter. FireBag valves are made of zinc-plated steel and can withstand 1500 degrees Fahrenheit for 90 minutes. They’re available in sizes from one half inch to two inch NPT, and can easily be used on smaller lines using a simple coupling. Models that include a shutoff ball valve are also available. Maintenance free for its entire life. The Teco FireBag provides a simple and effective way to protect lives and property from damage caused by fire getting fed by natural gas or propane lines.
