hand, self-locking, and non-releasable with a minimum unlocking strength of no
less than 50 pounds.
(f) Repetitive
Process Machines. On repetitive process machines, such as numerical control
machines, which require power or current continuance to maintain indexing and
where repair, adjustment, testing, or setting-up operations cannot be
accomplished with the prime mover or hazardous energy source disconnected, such
operations may be performed under the following conditions:
(1) The operating station where the machine
may be activated must at all times be under the control of a qualified operator
or craftsman.
(2) All participants
must be in clear view of the operator or in positive communication with each
other.
(3) All participants must be
beyond the reach of machine elements which may move rapidly and present a
hazard to them.
(4) Where machine
configuration or size requires that the operator leave his control station to
install tools, and where machine elements exist which may move rapidly if
activated, such elements must be separately locked out by positive
means.
(5) During repair procedures
where mechanical components are being adjusted or replaced, the machine shall
be de-energized or disconnected from its power source.
NOTE: "Participant" shall mean any other person(s)
engaged in the repair, adjustment, testing, or setting up operation in addition
