"Ken Sandyeggo" wrote in message looked around and
found that when my passenger placed her purse on the
floor next to her right foot, it pushed against the handle and shut
off the fuel to the header. The lever is so far tucked out of site,
hardly anyone ever uses it, or even knows about it, and I never
noticed that it wasn't safety-wired, which actually it shouldn't be in
case you need to shut off the fuel to the header. I safety-wired it
when we got back anyway. It flips off much too easily and there's no
way anyone could reach it in flight anyway.

If it can't be reached during flight, this might be a moot point, but for
what it's worth:

When I was C-141 mechanic in the Air Force Reserves years ago, we would
safety wire things like the battery box lid with copper safety wire
(couldn't tell you the gage, but it was thinner than normal safety wire).
The idea was that the copper wire could be broken with with human strength
in flight if the need arose.
