I remember from my misspent college summers working as an
instrumentation tech at a steel mill that one needed a special
detector to see a hydrogen flame. Those of us who worked at the
hydrogen-generating plant were warned about this. Hydrogen in
quantity is nasty stuff--we had to check our toolbelts, matches,
cigarette lighters and any steel pocket contents at the gate, lest we
would cuase a spark and ignite the stuff (the range of explosive
mixtures of H2 and O2 is very wide). I learned how blunt a
sparkproof screwdriver could get in no time at all.
Sigh ... I thought I typed *not* in their.
Cheers,
