B. LOTO at Circuit Breaker Service Panel
LOTO may also be implemented at a facility’s circuit breaker service panel. This method
should be used for hard-wired equipment or devices that cannot be otherwise unplugged
or turned off with a lockable switch. Note, all circuit breakers must be properly marked
with the machine/device that they power (see Figure A-3). Follow the steps below.
1. Turn off main power to the machine pair by switching the system controller main
power switch to OFF.
2. Turn off the service panel circuit breaker that powers the machine pair.
3. Place a circuit breaker lockout over the appropriate circuit breaker. Lock the circuit
breaker lockout using a padlock and secure a lock tag through the padlock shackle.
See Figure A-4. Alternatively, a padlock may be used to lock the service panel door.
Lock the door using a padlock and secure a lock tag through the padlock shackle. See
Figure A-5. In either case, the lock tag must be labeled with the name of the operator
implementing the LOTO.

4. If more than one operator will be working on the machine(s), each operator must
place a padlock and lock tag on the lockout device. Additional padlocks can be
locked directly through the circuit breaker lockout (if the lockout has multiple lock
holes) or can be used in combination with a multi-hole lockout hasp.
5. TEST. Verify that the machine pair is de-energized by switching the system
controller main power switch to ON. Wait 10 seconds. If the system controller
display remains off (blank) and there are no signs of machine activation (e.g. beeping,
clicking, LEDs on, etc.), the machine pair is de-energized. Otherwise, LOTO has not
been implemented correctly. Repeat Steps 1-4 to ensure LOTO is implemented
