    Not really just touch oil. To have a fire or explosion you need
    3 things: Fuel  the wax or oil Oxidizer  air or much much better
    oxygen or some other oxidizer such	as Oxygen, Chlorine or
    Flourine, stong peroxides   etc Ignition source this is usualy
    thought to be fire or a spark but other things such as friction,
    compression impacts etc can also start things going. 

    People are used to living in a world where the usual oxidizer is
    from air with an oxygen content of 21% you experiences are
    limited to that type exposure . If the oxidizer purity increases
    the ignition source rewquired and the intensity of the reaction
    increase very rapidly. A little boost in the oxygen concentration
    of air by only a couple percent makes a fire that melts most
    everything including refactories if not properly considered. The
    rate of increase is almost unbelieveable. 

    The rule of no fuels with oxygen is not somebodies dream. It is
    based on many bad incidents. Oxygen is tricky- you can get away
    with doing the wrong thing some of the time then bang you have an
    explosion or fire. Trust me I have seen and investigatedmany
    incidents of misuse. Jesse
