Turning the light switch off is fine if you know that no one can turn it
back on , either by having it in sight, or some kind of locking device. Even
putting a piece of tape over it with a tag to let others know you are
working on it.
I know an electrician that was going to do some work in a church. He pulled
the electrical meter out and layed it on the ground. That should have
killed all electrical power in the building. He started working and got a
big shock. He went outside and found out a man from the power company had
came by and noticed the meter on the ground , and had plugged it back in.
I thought I was clear when I wrote "as long as I have control of the
switch" and I put "it" instead of "is" when I wrote "treat everything
like it's energized, even if I know it's off". Whenever I pull a meter,
I always call the power company first as any sane person would. One of
the biggest reasons is to prevent any suspicion by the power company
that theft of power is going on. I always call them to let them know to
put a new seal on the power meter, if not, a lock will be put on the
meter and that will make it very inconvenient to do any more work
because one would have to wait for a lineman or meter reader to come by
and unlock the meter housing. Lockout tags and locking accessories are
not that expensive for safety and are mandatory in most industrial
plants. When I worked on Army Corps Of Engineers projects, there were
safety inspectors for both The Corps and my employer checking out
everything that was going on. One of my tasks was repairing power cords
that carpenters sawed in two. ^_^
