RuptureSeal RuptureSeal RuptureSeal

How It Started

  • Glenn Cox, the inventor of the RuptureSeal™ is a former Canadian Police Officer and Volunteer Firefighter who responded to a tanker accident leaking diesel fuel.
  • The police or fire department had nothing to stop the leak and watched helplessly while the tanker kept spilling diesel fuel.
  • The department of environment arrived 1.5 hours later and plugged the leak with putty and a piece of plywood that was propped in place with a shovel.
  • 15 years later he realized that leak sealing technology had not advanced since this accident.
  • He invented the RuptureSeal™ to meet the specific needs of the first responders.


Why Use RuptureSeal™  

Fuel and Chemical Leaks are causing serious damage each year to the environment.

IN THE UNITED STATES there are more than 70 spills reported on an average day. When oil spills occur, plants and animals will be contaminated and some will be unable to survive.
US Dept. Environmental Protection.


Companies are spending billions of dollars each year, cleaning up spills.

Oil spill clean up costs as high as $200/ litre.


Even small leaks cost thousands of dollars in clean up, not to mention the environmental penalties imposed by the courts.

In Alberta, CN received a $600,000 penalty, to be paid to the Wildlife Rehabilitation Society of Edmonton. In British Columbia, CN received a penalty of $400,000, which includes a fine of $50,000 and an order to pay $350,000 for projects in the Squamish River watershed.    *Environment Canada.




BURLINGTON, Ont. - A fuel trailer has rolled over in Burlington, Ont., and police say some of the leaked fuel may have entered a nearby creek. Halton Region police say the driver suffered minor injuries when the truck rolled over at about 8:30 p.m. Monday on Harvester Road near Century Drive. Police say there was a "significant fuel spill" from the tanker, which carried gasoline and diesel fuel, and some may have leaked into nearby Sheldon Creek. Area residents and their pets are advised to avoid the waterway until the extent of the spill is fully assessed.

Police say containment efforts are still underway.


MOLASSES TANK RUPTURE - August 9, 2011  

A giant, sticky mess from a 15-tonne molasses tank in Charlottetown was stopped last week when a local inventor brought his new product to the rescue.

Agro Co-op in Charlottetown did not notice the leak in the tank, which is used to store molasses for animal feed, until it was too late. It began oozing out of three small holes shortly after a fill up last Wednesday afternoon.

"It wouldn't stop leaking. It just kept coming out, coming out, coming out, and it was making a mess," Justin Skinner of Agro Co-op told CBC News Monday. "Our first initial thought was that we could weld the tank," said office manager Colleen Dean. "But with molasses being able to heat up it wasn't an option."

The RS2 is designed to plug leaks in a variety of applications. (CBC) Dean's husband had heard of a local company that might have a solution, and she called Glen Cox, president of Zengo Inc. in Stratford. Cox had invented a plug meant mainly to stop leaks in oil tanks. Molasses spills were not in the design specs, but he is still experimenting with the product and thought it was worth a try. Cox arrived at Agro Co-op a few minutes after getting the call. "After a minute of showing Justin how the product worked, and how to install it, the molasses had been turned off," said Dean. "It was amazing."

The RS2 is meant to be a temporary solution, and once the molasses level in the tank drops below the leaks, Agro Co-op will be able to weld them shut permanently.


HONOLULU HARBOR - September 12, 2013  

A massive spill of thick molasses has turned Honolulu Harbor into a watery wasteland where thousands of fish have been suffocated -- a disaster that officials say Mother Nature will have to clean up.

"There's nothing alive there at all," diver Roger White told NBC affiliate KHNL after making a seven-minute video of dead sea life blanketing the bottom of the harbor.

"Everything is dead. They're all dead and they're all just lying across the bottom -- hundreds and hundreds, thousands."

A pipeline running from storage tanks to ships spewed up to 233,000 gallons of molasses - enough to fill one-third of an Olympic-size pool - into the water on Monday.

The shipping company, Matson Navigation, said the leak was repaired on Tuesday, but there's nothing it can do to clean up the mess. Gary Gill of the state Health Department said officials were advised "to let nature take its course."

"Unlike with an oil spill, it's a sugar product so it will dissipate on its own," Matson spokesman Jeff Hull told NBC News on Thursday. "There's not an active cleanup."

The thick substance swamping the harbor and turning the water brown has already wreaked havoc with marine life. Crews have collected 2,000 dead fish but expect to haul out many more in the weeks to come, officials said.

"The molasses is not toxic but it's heavier than water so it's spreading around on the sea floor, displacing the oxygen-rich water down there, and the fish are suffocating," said Keith Korsmeyer, a professor of biology at Hawaii Pacific University. He said the sugar in the molasses helps bacteria to breed, and the resulting blooms also sap the water of oxygen. The disruption to the delicate ecosystem could doom coral reefs in the harbor, said Eric Vetter, a professor of oceanography at Hawaii Pacific.

The die-off also could lure predators like sharks, barracuda and eels to the harbor and neighboring Keehi Lagoon, experts warned.

"This is the worst environmental damage to sea life that I have come across, and it's fair to say this is a biggie, if not the biggest that we've had to confront in the state of Hawaii," Gill told KHNL.





April 2000: 800 Gallons Leak from a Dairy Near Somerset, England.

Wildlife was put at risk when 3,000 litres of milk was spilled into Galmington stream in Trull, Taunton, on Wednesday afternoon. Ben Woodhouse of the Environment Agency said:

"The problem is that microbes in the water work on decomposing the milk, which takes the oxygen out of the water causing the fish to die. But so far we have not found any dead fish. We think that, because it is quite cold at the moment, the microbes are fairly dormant."

The milk is thought to have come from a waste lagoon at a farm. - Western Daily Press

July 2002: 5,000 Gallons Near Staffordshire, England.

Fire crews are trying to stop the spillage of a tanker-load of milk from polluting wildlife in a Staffordshire lake. Firefighters spent the day pumping milk out into nearby fields and building dams to prevent it from flowing into the lake. David Thomas of the Environment Agency said: "Milk is a highly polluting substance." Some 50,000 fish are in danger if the milk enters the reservoir, which is a popular beauty spot and recreational boating lake. - BBC News



WINE SPILLS FROM TANKS - August 16, 2013  

Wineries at Riverlands Industrial Estate and Cloudy Bay Industrial Estate, south of Blenheim have sustained damage, but to what extent is unclear.

South Pacific Cellars winery manager Graeme Paul said all staff were safe, but a wine cellar and several tanks of wine had sustained "significant damage".

"There are tanks everywhere," he said.

"Several tanks have ruptured and there is some wine loss."

The building was too dangerous to enter, and he had sent staff home for the night, he said. 'It's pretty dodgy in there." The volume of wine lost was unknown.

Saint Clair Family Estate senior winemaker Hamish Clark said one of their 300,000 litre tanks holding 2013 sauvignon blanc had ruptured. They had managed to save most of the wine by pumping it into spare tanks, but the loss of wine would probably be in the ''thousands of litres'', he said.

STATIC AND THE FIRE TRIANGLE - Letter dated April 18, 2012 from technical risk services - Bruce Gilder, president

In order for a fire to occur, the fire triangle as it is known in the fire protection community must be complete.

The fire triangle is composed of fuel, oxygen and heat. All of these elements must be present for a fire to occur.

In the process of insertion of a RuptureSeal™ product into a rupture of say a vehicle's gas tank, the fuel is definitely present.

Since the insertion is into a stream of liquid (albeit flammable/combustible) oxygen would not normally be present.

Even though there could be metal to metal contact (The RuptureSeal™ pin & metal tank being sealed), a spark (defined as a small glowing particle typically caused by a non-continuous arc of electricity) would have to be the source of the heat element to complete the heat triangle.

In my opinion, since the RS-2 is inserted into the actual stream of liquid that is escaping from a tank, the oxygen component of the Fire Triangle should not be present. Also the heat component (typically a spark) would also not exist unless the heat came from an external source.


  • As with all potentially hazardous materials, necessary precautions must be followed to assure the safety of the user.
  • This may include ancillary equipment, personal protective equipment, training and constant monitoring of leak after deployment of unit.
  • The RuptureSeal™ unit should never be considered a permanent solution to a leak or rupture.
  • Refer to manufacturers MSDS for complete information regarding handling, clean-up and proper disposal of all hazardous materials.


* Had little to no effect on the components of the unit.
** Had partial effect on the components, reducing units holding time.
*** Had severe reaction with unit, holding time greatly reduced, use not recommended.

  • Performance of the RuptureSeal™ products on acid leaks will vary dependent on the type and strength of the acid involved. Generally, acids with a pKa value similar to acetic acid (4.75) (pH 3.4) should be safe to use with the RuptureSeal products.
  • The sealing time capabilities of the unit will be reduced with stronger acids. If it is necessary to increase sealing times beyond the products capability.
  • It is recommended that you have multiple RuptureSeal kits on hand and replace as time dictates until the leak can be fully contained..


  • RuptureSeal™ products are now being used by Armour Transport, Atlantic Pacific, Trucking, Transocean, CN and CP Rail, Halifax Airport, PEI and NS Dept. of Environment, and Several fire departments around the world.
  • These are just a few of the companies that have successfully used our product.

Dear: Glenn
RE: RuptureSeal

I just wanted to send you a note about your product. Our crews and I have used the RuptureSeal out in the field on several occasions and on countless training exercises. We have always had great success with the product and have rolled it out to our transport division and they now carry the "kit" on each unit.

We have had the occasion to use the RuptureSeal in various situations involving different products and have always had the same feedback "this sure beats the other products". We now share the RuptureSeal with our partners and clients as a best practice.

I have pictures available of your product in action if you need or want them please let me know.

Yours truly,

John M. Stull

"A vehicle inbound to the airport was struck by something on the undercarriage, rupturing the fuel tank. As the vehicle slowed down and approached the airport, it became apparent it had sustained a serious leak. Our Fireman responded, got under the van and installed the RuptureSeal, stopping the discharge immediately. We were amazed at how well it worked and will definitely keep the product on all our trucks."

Gordon Duke,
Director of Operations
Halifax Stanfield International Airport

"The RuptureSeal system uses a unique approach to seal holes in fuel tanks or other structures. As a response contractor for fuel truck accidents and for marine spills I immediately saw the potential for this device to be used effectively in our industry. This device offers several advantages over existing methods, including improved safety for responder personnel."

Robert Starkes,
Manager - ECRC Atlantic Region www.ecrc.ca

Accuworx is an emergency response and hazmat contractor. Accuworx was deployed to a release of mixed liquid goods from drums and totes. The liquids varied from acids to bases. The release was due to vandalism. Accuworx vacuumed up the liquid and deployed 3 different sized RuptureSeals to totes that would allow for collection of product latter on in the project. The product is very easy to deploy and training for staff minimal.

Testimonial from Donald Lamarche,
Deputy of Occupational Health, Safety and Environment, QC, Canada.

This happened a little over a year ago, when one of our barrels was pierced by a piece of equipment, and back then, we had absolutely no way of stopping such a leak, so we had to use a manual pump to transfer the liquid from the pierced barrel into a new one. Fortunately it was not a dangerous product, or else I cannot imagine what the consequences could have been, had we been dealing with a hydrocarbon or any other flammable substance.

Every week I receive an email focusing on health and safety and this one spiked my interest and curiosity; there was an ad for a product that had just been on the popular TV show "Dragon's Den" that was intended to do just that, stop leaks quickly. I directly went to take a look at the demonstration video and see who I could buy this product from, to realize it had been on the market for quite some time already. I bought a 3 unit kit of a product called "The RuptureSeal'" (see photo below).

Now, we are definitely ready to avoid these types of accidents and prevent any major leaks from happening. I recommend this product to all companies who wish to be proactive in preserving the environment.
