It is obvious from these numbers that a lot of people do more than one
thing to limit access.
A couple of people also suggested yellow/black floor tape. My experience is
that, while it is useful to have it isn't enough to stop people.
We are currently using signs and floor tape. I think that we are going to
try to use a combination of a keypad lock, plastic chain, coordination
with management and escorting workers.
I think this is a problem that we can best solve by a combination of
approaches because if we have a single technique and it fails we have no
protection at all.
Thanks Again,
