You hit upon something that is very dangerous to any that runs a large
coil
in their garage. The greatest danger is that if a spark strikes a wall,
travels thru the wall seeking a ground source such as a wire, the
dissipated
energy within the wall construction materials may not lead to an immediate
fire which can be detected and extinguished. The greatest danger is the
smoldering of construction materials which continues to smolder and
eventually breaks out into a fire a few hours after you have retired for
the
evening.
You could simple string a grid of 12 inch spacing of enameled magnet wire
(sand off the enamel) at intervals along an adjacent wall such that any
errant sparks will strike the grounded magnet wire grid and not go into
your
wall where it could cause a fire hours later. A 1/2 of a dozen wires in
nearby areas gives the spark a definite ground attachment point and will
prevent fires from forming as you snooze. Of course, this does not always
occur but it only has to happen once to give you a real bad hair day.
An example I can recall from recent memory is in the photos in Dan
McCauley's book on soild state resonance transformers. The sparks
striking
the wall could have been seeking grounds in construction materials which
could several hours later burst into a large house fire. Again, this did
not occur, but it's like driving on bald tires. A blowout (or flameup)
only
has to happen once to give you a bad day. This is an extreme example of
exactly what NOT to do under any circumstances. Use ground wires on the
interior surface of the wall or do it outside ---- NEVER INSIDE YOUR
HOME! If you insurance company ever saw a photo of this occuring you
could
be cancelled immediately!
Safety first and happy coiling!
