    Leak detector is not the same has soapy water. If you go to Highside
    Chemicals web page and then check the GAS LEAK DETECTOR
    http://www.highsidechem.com/pdfs/gasleak.pdf

    You will see that it is not just soap and water. It has agents added
    to be fluorescent and also to modify it's viscosity as well as it's
    low temperature behavior. Therefore their warning in reference oxygen
    equipment may be justifiable. However to leap from taking a chemical
    product and extending it to "all leak detecting solutions are
    dangerous around oxygen would be like taking the warning about nitric
    acid and saying it is dangerous to use Vinegar on my French fries,
    because both are acids.
