I removed this post because it was going against forum rule.

When I was in Iraq the first time, in 2003 -2004, one of our missions was to protect a propane plant that had nearly 300,000 trucks a day come and fill their little propane bottles with propane. I remember the Iraqi's that were filling the bottles with propane lighting up as they were filling bottles. I was never impressed with the ignorance. Propane is highly flammable, and can combust with the slightest ignition source. I think it is very imature to use such a gas to purge with. I am sorry if this seems like an attack but it is not encouraged here on the forums to use propane to purge anything. I do not recommend purging with propane and I highly discourage it.

lol, I work with the stuff and can say you have no idea what your talking about, but what ever. I am staying nutral and all I am commenting is on the gas its self.

The chances of just a light cigeret igniting it isn't all that great, usualy you need open flame or an arc, I'd be more concerned about static then a lit cigeret.

You need a rather perticuler mix to get an explosion any thing higher it burns with a wave front, any thing less nothing happens.

PLEASE STOP spreading MYTHS about it. Scare tactics using myths is counter productive to safety.

Flammability range in air is 2.2 to 9.5 % and amout of chemical energy is massive and there are many scenarios of what can go wrong............ that I,m sure your not even aware about.

It is violated forum policy not to talk about purging with flammables .

everyone was warned by runmc.

you buy a regulator & small bottle to hold nitrogen,if you must you can find a cheap one on ebay.

You spend thousands on your PC rig but can't afford another 100.00 for your safety and that of your family.:mad:

I tired of hearing funds as a excuse:nono: ,as many spend thousands on their rigs plus usually much more for advanced air or water cooling before they move to phase.:fact: then they want to getto every thing,even safety equiptment.

Every hobby has a cost,so find the money or wait till you can afford to build a safe rig. Thats my opinion.;)

I know dam well what can go wrong, we ran the sims of pipe ruptures and how to deal with them. I say whats needed, not what isn't, the tanks had their own safety systems and thus we didn't need to be concerned with them to a degree other then general maintanance. Fear tactics are an idiotic way to sway people away from doing some thing, Honesty is the best way, as when they learn the BS you been spreading they will trust nothing of what you say.

No I did not violate forum policy, I did NOT recomend it, I did not even totch on the issue, I just asked he keep things within reality. Nothing more, try reading the post next time.

Nitrogen; Argon; Helium; Or even CO2 how ever not as good of an option as the other gases will work well.

There are better reasons to not sujest using R-290 as a purging gas, one being is that it contains moisture and under heat sulfer traces can form acids, this would be a far more valide reason to recomend against it. If we are concidering legalities then you all better stop this site now as making units un-lisanced is indeed illegal, lets keep things in perspective!

Yes you did xeon :you said:

"PLEASE STOP spreading MYTHS about it. Scare tactics using myths is counter productive to safety".

They are not myths, R290 is not even allowed to be used as a refrigerant in the USA as OSHA & government regulating agencies deems it to dangerous.


please post the book??????? that teaches you to test 300+++ liter systems with a blow torch or lighter.:stick:

So USA is behind on allot it is commenly used in Erupe, and if things keep going good in Canada as well. And in the US it is used in stationary systems as a part for mixed refrigerants.

What I am talking about is the over hyped dangers of it, can it be dangerus yes, not in the way you are painting it, this infact makes it even more dangerous should thees guys ever enter a shop where they have to use it. That is feild reality that teaches that, no book.

You never use flammable gases with home made ghetto solutions,whether its the gas stove or grill or your propane torch or something else.

ONLY equipment approved for its safe use should be used, and used following all the safety guidlines.Period end of story.

The rest of your post don't justify me wasting my time to reply too.

[Xeon th MG Pony]

Where did I say other wise? You still haven't figured out how to read posts I see, so this explains a lot.

[Sneil]

sorry for mentioning propane, didnt know it was against forum policy now. I dont come here that often. sorry for bringing it up.

[runmc]

Sorry for all the edits guys but I felt it was necessary.

We do not allow the discussion of purging with flammable gases in these forums. Since it is not a posted rule there will be no official warnings. It is also against forum rules to flame other members. That is a posted rule. Please keep discussions in a friendly tone.

When did it become a myth that propane can explode?

[m411b]

Sneil, I apoligize for the attack. I did not intend for it to seem as one.
I didn't expect this thread to turn into an argument either.

[Xeon th MG Pony]

It can thats not the myth it is how easy people try and make it sound, there are many events that have to be just right to pull off it exploading, IE raging incompitance by the opperator and horrorendus failures of maintanance and such, In other words the ones that manage it we call natural selection.

When people over hype some thing it can lead to the oppisite of the desired goal. While filling tanks the leakages of the hydrocarbon are so low it would be hard to get a constant flame let alone any thing ells, still a bad idea just becuase it is a fuel but not dangerous providing the rest of the system is maintained (Only high risk facter is when he disconnects the feuling line from the tank). IE Smoking around any fuel is stupid due to the risk that a pipe could rupture or come loos how ever under normal situations that risk is very low and idealy non existant.

Frankly nothing ever should be "ghetto" that is un-acceptable type of workman ship when dealing with any pressure related device, cheap by all means but "ghetto" implies well beyond substanderd.

ALL hydrocarbons carry risk with them, how ever are not dangerous, just the people handling them are dangerous just as electricity or a motor vehicle. The pressure thees systems opperate is a much greater risk for people making thees systems due to some learning to braze and such. I feel fare to little is mentioned about the dangers of high pressur.

Any Case I apologise to you for jacking your thread.

[ak_47_boy]

Purging with flammable gasses is not dangerous unless:
1. It is in the perfect mixure in large volume & in a container.
2. You are tripping on various substances.

If you have p*****nfobia buy yourself a paintball co2 tank and a fitting, it will cost about $50.

It works every time :D
