Trapped Gasoline Using the principal of liquid adhesion, we used colored water to illustrate how the small holes in the FMD’s walls are designed to trap gasoline. Just like rainwater is trapped in a screen, liquid adhesion causes around 5 grams of gasoline to be left behind in the hundreds of holes in the bottom and sides of the FMD. As a flame or spark gets closer to the holes filled with gasoline, the trapped fuel causes an noncombustible atmosphere within the FMD cup. This is a very effective barrier and prevents the flame from advancing into the interior of the can. |

This is an example to show our FMD is designed to allow gasoline to flow normally both into and out of the can. This garden hose flows between 8-9 gallons per minute. This is about what a normal gasoline pump puts out at full flow. You can see the FMD was designed to maximize its flow characteristics. |

This animation explains the science behind our FMD. |

Testing of FMD conducted at Oklahoma State University (inside shots) and Eastern Kentucky University (outside shots). Both sets of tests used 100 to 300ml of weathered gasoline (@75% of original mass) over an open flame to test for jetting and/or internal combustion. The test @ 50 seconds was taken to full conclusion. The last test @ 1:30 had a nozzle on but with zip ties holding the valve open. It too went to conclusion and burned a hole in the plastic can without evidence of internal combustion. In all testing, no jetting or internal combustion was present when the FMD was installed. DO NOT TRY THIS AT HOME! EXTREMELY DANGEROUS! These tests were conducted by professionals in controlled environments. The tests were meant to simulate a dangerous example of portable fuel can misuse. We do not guarantee the performance of this FMD. We only show these example videos of testing we have performed. Always follow all warnings and cautions on No Spill fuel cans and use common sense when using our fuel cans. |

Flame Arrestors Metal fuel safety cans have a small cup made of steel screen called a flame arrestor. Flame arrestors stop flames or sparks using an entirely different principal. It stops a flame’s progression into the interior of the fuel can by thermal quenching. Thermal quenching lowers the temperature of the flame by absorbing and dispersing its heat so it can’t progress through the screen as seen in the video. Flame arrestor quenching technology can be found in many applications and has been around since the early 1900's. It is an entirely different approach than C2R. Why not use a flame arrestor in a plastic fuel can? The possibility of static electricity. While it is a low probability, static electricity may be generated by pumping gas quickly through a metal screen if conditions are right. The screens can be grounded properly with a metal safety can. They cannot be grounded properly if in a typical plastic fuel can. |

Flame Arrestors do not control mixture inside To demonstrate flame arrestors used in safety cans work differently from the C2R FMD design, we wet both of them in gasoline and attempt to ignite the atmosphere inside them. Both metal flame arrestors ignite almost immediately as the fuel to air mixture inside them is combustible. This does not mean they are ineffective, they simply work in a different way (quenching) to stop a flame or spark from advancing into the interior of a can. (Please see video above.) |
