The only extinguishing agent is contained within the length of the tube itself, that’s not enough volume. Like any decnet fire extinguisher, you need capacity.  The bigger the better.  With no additional agent reservoir, thats a few seconds of discharge at best, totally dependant on the size of the failure in the tube?  So think something like, phfffft , , , , , , and done.  It might extinguish a small fuel fire, in a small space for a second or two, but it has not cooled the heat sources inherent within an engine bay and if the fuel is still leaking, re-ignition will be a reality.

 

Then directionality and spray pattern become issues, (as will the cable ties)  OK, the tube fails and releases the agent, what’s to say it is actually directed at the fire and not spraying it against the firewall?  Again, this might work (extinguish) within an air tight space, but the air-cooled engine bay is fairly well ventilated, we hope.

 

A quick check of the web site and itmakes no mention what the “clean agent” is, so it’s hard to predict what might actually happen.  And the web site makes no mention of any product testing, certification or listed by any independent 3rd parties testing labs within this country, or any others from what I can tell?

 

And, no demonstration videos of it working, wonder why?

bin55 points out some veeery valid questions...What is it??...a simplistic tube with something in it valued at well over 200 dollars!!!

 

Hummm?

 

I'll bet there are a dozen chemical knowledgeable members on this forum that could duplicate this primitive 'extinguisher' for less than 30 dollars...including a two color confidence inspiring instruction sheet.

Scott:

 

I would imagine that their website is designed with sales generation in mind. I looked at the videos on the Blazecut website.

 

That said, an independent, third party, test or evaluation would be beneficial.I am certain there are testing labs for fire suppression systems just like there are for electronics, etc. (Underwriters Laboratories for instance.) For me, two guys who want to sell this thing to me   setting fire to old truck in a junkyard isn't quite the standard I'd accept.

 

I wouldn't buy this thing without that independent testing and trust that my car was safe. Note there is no sign of a guarantee or indication that they really back this thing up. It is what they don't say or advertise that makes me wary.

 

I'd be much more likely to invest in a tried and true system, though probably considerably more costly, than toss out $200.00 plus because this thing is popular in Europe so the seller says. I don't have any interest in any company that sells fire suppression systems so I don't have an axe to grind.

 

I also don't have an interest in buying a product that seems "iffy" in it's ability to protect my car, at best.

 

Only my opinion and virtually worthless to anybody but me.

Hopefully, no one would seriously consider purchasing an unproven unit such as this.  This "extinguisher" is probably legal to sell ony in instances where an extinguisher is not required.  Note that extinguishers in the US are tested, rated, and qualified by ANSI (American National Standards Institute), UL (Underwriters Laboratory), and NFPA (National Fire Protection Association).  That's how we get extinguisher ratings, such as ABCD, I, II, etc. that tell the consumer what type and size of fire this unit is made for.  

 

This extinguisher contains no rating and claims that its flammability is what makes it effective, since it will melt at the hottest spot of the fire.  In addition, there is no inspection gauge that indicates the level of "clean agent" present.  This is the worst kind of subterfuge, since the buyer will now think that he is protected.  Avoid at all costs, but I'm sure you guys already knew that.  If you want adequate fire protection, spend a few bucks on an approved system or extinguisher, develop an adequate maintenance and inspection program, and hope you never need the extinguisher. 

Bob:

 

I mounted it on the firewall, so the nozzles (one at each end of the canister) are right above the carbs, as I understand that's where most fires begin.  I got the idea after seeing Henry install it in some of his cars.

 

It's item 50-1025, 26.25 inches, for a Porsche 911.  I realize it's overkill for my car, but better to be safe than sorry.  They aren't cheap, but it's good insurance.

 

 

Tom Blankinship has also installed one in his Speedster.  Halon seems to be the best/cleanest fire suppression agent, although I trust I will never have to use. it. 

The site had an MSDS. The agent is Hexafluoropropane a liquified gas.  The byproduct of combustion is Hydrogen fluoride which is (according to Wickipedia):


"Hydrogen fluoride is a highly dangerous gas, forming corrosive and penetrating hydrofluoric acid upon contact with tissue. The gas can also cause blindness by rapid destruction of the corneas."  Then a little dab of H2O and....

" Aqueous hydrofluoric acid is a contact-poison with the potential for deep, initially painless burns and ensuing tissue death. By interfering with body calcium metabolism, the concentrated acid may also cause systemic toxicity and eventual cardiac arrest and fatality, after contact with as little as 160 cm2 (25 square inches) of skin."

Hi Guys-

 

I am the seller of this system.  You all raise a lot of good questions in this thread and I will do my best to answer them for you.

 

The Agent is Hexaflourapropane otherwise known as DuPont FE-36.  There is an inherent risk with any sort of chemical, period.  I would not place this in a passenger compartment.  FE-36 is the replacement for Halon, and Safecraft uses Halon 1301/1211 or FE-36 in their systems.  From DuPont-

 

"DuPont™ FE-36™ is proving to be the standard in-kind replacement for Halon 1211 in portable fire extinguishers. DuPont™ FE-36™ has comparable performance and efficiency to Halon 1211, lower toxicity, as well as zero ozone depletion potential. In a portable fire extinguisher, DuPont™ FE-36™ is discharged as a stream of gas and liquid droplets that penetrate into the fire area, ceasing the combustion process through heat absorption and a chemical interaction."

 

There is a gauge on one end of the tube.  There are pictures of the gauge in the listing.  Same as what was said Bob 2004 IM stated, as long as it is in the green you are good.  It will only "go bad" if you develop a leak in the system somehow.

 

The zip ties are rated at a higher temp then the tube.  If the zip ties are a concern for you, There is no reason you could not use an alternative mounting method, but it is not needed.  Eventually a zip tie will fail, sure, after what, 5, 10 years?  That is acceptable maintenance interval for me.

 

The Blazecut website does have video's of the product working, Bim55.  In my opinion they are not that great of quality videos, so I made my own.  I finished it yesterday and have now posted it as well.

 

Re-ignition is always a concern for a fire like this.  I have Blazecut installed in my bus and also carry a fire extinguisher in the cab.  The only way to be 100% safe is to not drive your car, which isn't an option for me!

 

MangoSmoothie-  I am interested in what you got for $60.  Please give us details!  If you have a system like this available for $60 I will buy a bunch.

 

I would not put this on the same level as a safecraft system.  Safecraft is designed for race cars.  I consider this the "homeowner" version.  It is a great, simple system that you can install in a few minutes for extra piece of mind.  For people with classics or original condition vehicles you can install this without drilling holes and fairly discretely which I know is important to a lot of folks with pristine engine bays.  

 

I will find out what certifications the product carries and update this post.

 

If you have any other questions, don't be afraid to email me through the site or directly at sameshirt@gmail.com.  I think it is a great product.

Ditto here.  Had I not invested a goodly sum in my Safecraft unit, I might consider this.  Although, as said above, a second extinguisher in the passenger compartment is a necessity.

Respect for jumping into the middle of the hornets nest.

 

my fire suppression system:

i only made one. for me. 

Thanks guys.  It is a new type of system for the US, so I know there will be lots of questions.  I'll do my best to answer them.  We all love our vehicles and do the best we can to protect them.

 

MangoSmoothie, that is a great DIY system you put together.  Being handy is worth its weight in gold.  I hope you never have to use it.  Is your 356 Mango Green?  My 61 Mango bus is part of my family.

 

JOGR,

 

You may have the best of intentions, but your business model is backwards.  Most folks would research the product they are selling first, including finding out if it is approved by the relevant authorities, then offer it for sale.  Seems like you have offered it for sale, and now will try to see if it's approved.  Kind of like selling tires then going to DOT to see if they are even rated.

Jim-

 

I'll have to disagree with you on that.  I am not marketing this to race cars or any sort of regulated activities that have stringent quidelines for product approval and use.  I can tell you do not like this product, and that is fine.  But I do want to address your claims so that there is no misinformation.

If you watch my video, I would consider that proven.  In situations where a fire extinguisher is required, say in a race setting, you would want to familiarize yourself with those regulations and buy an appropriate unit.  SFI-approved is what you would need in that scenario.  Blazecut is not SFI approved and I am not marketing the product towards that demographic.  I am unsure what you mean by the rest of that, as a fire extinguisher is not required in your engine bay to drive around on the street...  and that is exactly what this is for..  So I think you are making a "dig" on the product, but that is what it is for.  

 

FWIW, I am looking at the Safecraft site, and reading about the RS series, which is their least expensive option.  Some are SFI certified, some are not.  The metal cylinder is DOT approved.  That is the only mention of certification and testing I can find on their site.

Blazecut is ABC rated.  There absolutely is an inspection gauge and it is pictured on the samba listing and on my website and on blazecut.com.  I am wondering how well you looked at the info, or why exactly you are so against it.  Every "automatic" fire extinguisher product relies on heat to activate, whether it is a safety pin that melts away or this tube that melts.  In my opinion this is a benefit.  You can route the tube through the danger spots and the fire will be extinguished with a large discharge focused directly at the hottest part of the fire, before the entire engine bay is engulfed in flames.  The "Clean Agent" is FE-36.  Subterfuge is a strong word and frankly it offends me.

I have researched this product first, but certifications are not required for the applications in my target market, therefore that info was not important to me.  I wouldn't compare this to a tires DOT certification, i think that is a long reach and not a fair comparison.

 

You do not have to have a fire extinguisher in your engine bay.  You don't have to have one at all.  I have driven my bus for years without a Blazecut and everything has been fine.  If you want to install something like this, I would research the options available and pick something that you are comfortable with and can afford.  I did, and am very happy with Blazecut and am proud to be able to offer it other hobbyists and collector car owners.

 

Thanks for the interest and questions.

Thanks for the interest and questions. 

Wow.  I like this concept.

 

A few more questions come to mind. 

 

How suseptable to "false positives" is this hose.  Is there any way the hot ambient temperature could trip it?  Friction from vibrations in engine compartment wearing thru?

 

Seems a bit long for our engine compartments?

 

Otherwise, I am tempted...

Hi JOGR,

 

I am not against your prouduct if it is approved.  You state thata it it ABC rated, but I see no proof of that, nor do I see any mention of it in your ads.  You also seem to state that you are not concerned about approval, since you are selling it to users who don't require an extinguisher that is rated.  To me, that's the same as saying that the life preserver I am selling is fine, trust me, even though it is unrated, since you don't really need an approved life preserver in your case. 

 

If your device is approved by NFPA or UL, where is the approval sticker mounted?  I didn't see one in your material.  If it itsn't approved, why not?  I am not attacking you personally, but if you are selling an unpermitted device, you are placing your customers at risk.  Underwriters Labratory does an excellent job of rating all types of devices, and weeding out those that fall short of the safety standards needed.  I would think that you would proudly display your UL certification.

No, "use case" comes into play.

 

To quote "Empi" which I am sure we have in all of our Speedsters in some form:  EMPI® does not warranty the legality of its products, which do not comply with Local, State, or Federal Laws. We recommend that you check local regulations prior to ordering or installation. -or- Not for highway use. For off-road use only. :-)

 

The above product is simply not approved by certain organizations.  UL, etc.  Just like the FDA when it comes to "Supplements" in you local Organic food store. ;-)

 

I agree with Kelly's rational and legitimate skepticism...Why is the question of NFPA or UL certification being skirted?

 

But I approach the efficacy of this product from a dollars and cents perspective

 

What is the cost/value of open heart surgery if it will save you life?...Whatever the traffic will bear, of course.

 

What is the value of an item fabricated at a cost of 40 or 50 dollars (at most) if it will prevent your car from melting?...$225? Hummm! Is this what the traffic will bear?

 

Since there's no comforting certification of this questionable product, then Take a closer look at Mango's innovating solution...and your pocket book!!!

Hi Ronin, melting point for the hose is 120*C or 248*F.  I know it is hard to tell without holding it in your hands, but the tube is very tough, it is resilient and as long as it is secured and not allowed to wiggle around up against something sharp it is nothing to worry about.  It is 6' long and contains 1lb of FE36.  It is perfect for smaller engine bays.  There is a ton of empty space in a bus engine bay and you can see how well it extinguishes in the video.  In a beetle, or your 356's, I would just install it as a spiral or double back on itself if space is an issue.  You would not want anything shorter as the length determines how much chemical is available.  Blazecut offers a 12' tube as well, Which i will have on the next order, but I believe is overkill (for the uses I have previously stated, of course, bigger couldn't hurt).

 

 

Jim-

Blazecut is not UL listed.  The ABC rating came from my inquiry to Blazecut earlier in the day.  I have suggested to Blazecut that they submit it to UL, because it would help ease the fears of some people.  I suggested this even before I was turned on to this thread.  

 

I guess it is just your analogies and terminology that I have a problem with.  It could be like the life jacket I guess, except I would say here is this life jacket, look over there at it working on that guy in the water.  It is a new type of life jacket, it is not listed as a floatation device yet, but man does it work great and the price is right.  You don't have to buy it...  Look it over and see what you think.  

 

This is the first time the product has been available in the US.  Blazecut is located in the Czech Republic and has not sought UL approval, as it is not required.  

 

I also think the term "unpermitted" is misleading.  Unpermitted for what?  I already stated what this device is for and there is "no permit required" so to speak.  How am I placing my customers at risk?  If you think using this is risky, I would suggest you do not buy one.  I wanted to see exactly how these work, and to be able to confidently sell these to my fellow enthusiasts, which is why I went through the trouble of creating the video I posted earlier.  For me, and lots of other people, seeing is believing, and in this case, you will just have to trust me, the product, and your own eyes.  If you choose not too, that is your choice and that is fine.

 

Todd-  

This product is not against the law.

 

I don't really have anything else to add.  I am grateful for the interest and it is my hope that some vehicles will be saved by this device that would have been lost if it were not installed.

 

If you have more questions please email me.

 

One last thing, I am all for DIY solutions and I think Mango Smoothie's solution kicks ass.  I really do.  But to be fair, and compare apples to apples, on his website he stated $80 for initial parts, then he bought a second extinguisher for testing purposes, which is it was the same as the first one is another $32, and two fancy T bolt clamps at $6 each.  That is $124.  What do you value your time at?  How long did it take to fabricate and install?  Do you want to drill holes in your car?  Do you want something automatic or that you have to pull the handle for?  Like I said, I have a lot of respect for his solution and I do think it is great, but it wasn't 40, 50, or even $60.
