    Acetylene explosion

    Saw pictures of a different one in school when a leaking tank was allowed to fill up a van and a remote was used to unlock the door...incredible damage to nearby homes.

    Always close the valve when finished. He probably had it rolling around in there too.

    I irritated a senior installer once by closing my valve when I was done outside and carted the rig inside. I don't trust the torch knobs for any length of time and keep the valve wrench poised to be slapped off in an instant.

    You should always turn the tank valve off when finished and then turn on the knobs on the torch handle to bleed the oxygen and acetylene pressure in the hoses and on the back side of the diaphragms in the regulators. Always.

    Back in the day when I was a product engineer at Carrier I fired a line supervisor for repeatedly ignoring my instructions to turn the bottle off.

    Acetylene, when mixed with even small amounts of oxygen is one of the most volatile substances on earth. It also is one of the hottest flames known at around 5500F.
    The picture in my avatar is of the Houston Ship Channel and was taken from my backyard. I like to sit outside and slap mosquitos while watching countless supertankers, barges and cargo ships of every shape and size carry all sorts of deadly toxins to and fro. It's really beautiful at times.....just don't eat the three eyed fish....

    Yikes...I thought it was around 1900*. Anyway, I'll never forget getting dinged on my first semester final in school for not closing down the rig properly.

    I turn it off in between welds for many reasons.

    When working with Acetylene You need to know the "no no's", Ya know.
    Same with O2.
    And these gasses are not regulated.
    Not that I want them to be.
    Never argue with a crazy man.

    Any one heard of "redtek"? Its the HC (R12a) replacement for R134a . "Redtek" is not acetylene but its a hydrocarbon and it will fuel a fire. I wonder would happen if a vehicle charge with "redtek" had an evaporator leak , and someone press the remote to open the car?

    Nothing.

    R-143a's replacement, HFO-1234yf is a flammable gas and has been proven to not be ignitable under even the most abnormal conditions.

    Redtek is perfectly safe, look it up.
