This is a sad, sad, sad deal . R.I.P.
Racing by it's nature has danger but i.m.o. spray is something that should have never been allowed in the gate . I known this sounds monday morning quarterbackish but I've felt this way for a long time.
Not a safety issue.....the same goes for delay boxes...if the guy guy sitting next to you does not have one you aint gonna have to buy one . The NOS and box people sponsor races so that's the way it'll go i.m.o.

An unfortunate accident, thoughts & prayers go out to the family.

In my opinion there shouldn't be any more problem using a compressed nitrous bottle in a race car than there is using any other compressed gas bottle in a work shop, or a compressed oxygen bottle for someone with a respiratory breathing problem in their home/work. I feel heating these bottles (no matter the method) is the actual problem, especially the composite bottles.



Went looking for other bottle accidents & found this that happened in 2009, another thought to be caused from micro fractures from repeatedly heating the bottle over & over......

If there is no bottle to heat.........there will be no issue.......no matter what it is made of.

Composite bottles have the same problem as composite driveshafts, you just never know when they are going to fail unless you x-ray the part.

But even without a nitrous bottle a lot of race cars still have a high pressure compressed gas bottle of some sort that could also possibly fail such as a CO2 bottle or the fire system bottle(s).

They should just outlaw heating the bottles period. Then the risk is the same for nitrous bottles as it is for the CO2 & fire bottles.

I do not see the need for CO2..........but I do not think they are heated.
Fire bottles seem to be a fuel car/dragster thing .......which I will not address......I have no knowledge of the weird stuff.

A lot of bracket cars use CO2 bottles for the throttle stops & timed air shifters.

And if someone is using a Bruno/Lenco trans setup, a CO2 bottle powers the trans brake in the Bruno Drive & can also power the shifter air pods on the Lenco trans.

As far as the fire bottles go, most any fast door car class that uses a power adder (blower, nitrous, or turbo) has to have a fire bottle/system. And even without a power adder, the Pro Stocks have to have a fire system.

It was just an unlucky incident. May God bless him and his family.

I ran nitrous for years with no troubles but I did see a truck totaled one time in a Whataburger parking lot when a guy left his full bottles in the cab on a 105 degree day. As far as nitrous safety is concerned, I am fine with having it at the track but the heating should be better regulated an they should have to be re-certified. I have two pressurized bottles in the cab with me, CO2 and fire system, and I used to ride with a nitrous bottle passenger and have never feared for my life because of any of those.

The worst dragstrip accident I have ever seen resulted in a death also and that was when a fellow racer was airing up a tire on his Peterbilt toterhome. The sidewall let go and killed him instantly.

Let's just let this one go and pray for his family.

Standing in the staging lanes & seeing a guy break out the propane torch will make you cringe & look for a place to duck even before he starts heating anything. The biggest WTF moment comes when you realize it's like 97 to 100 degrees in the lanes & some guys still reach for the torch. Rolling Eyes

Sad thing to see.

Here's my problem with bottle heaters: The intent of a bottle heater is to raise the temp of the N2O INSIDE to a desired pressure. So they heat the OUTSIDE of the bottle in order to induction heat the N2O inside. Due to thermal losses, this requires the bottle to be be raised to a much higher temp than the nitrous itself needs to be at to raise the pressure. What I think they should do is manufacture bottles with a heating element manufactured INSIDE the bottle and heat the N2O DIRECTLY without subjecting the bottle itself to all those thermal cycles.

I was talking to our local track owner last night. He is a friend of the family. He said that the bottle was dropped and knocked the valve off. That was when all Hell broke loose. He said that the bottle shot off like a missle. Crying or Very sad

I personally dont know what happened, this is just what was told to me.

Actually, the principle is not "thermal losses" - you're on the right track though - it has to do with temperature differential.

Speaking generally, to heat a medium to a desired temperature like 80 degrees from 40 degrees, if you apply an 80 degree heat source, the medium will start to go up in temperature quickly at first, and the ramp-up will diminish as the temperature differential gets smaller. Applying a 120 degree heat source until the 80 degree setpoint would maintain a greater differential throughout the heating cycle, thus reducing the heat time. This is the case with purpose-built bottle heaters. I'd consider the water bath setup the guys on the site have posted about to be the best, as it's the most uniform way to apply heat to a bottle.

In the case of these idiots who use torches, the heat is highly localized - which is the cause of the stress which weakens the bottle itself. Yeah, the differential is there, but again highly localized (think: World Trade Center structure failure Crying or Very sad ).
