6.1.1 Lockout / Tagout (LOTO) Instructions
NOTICE
The equipment
must be locked
out for most
procedures in
this chapter.
All energy sources for equipment on which work will be performed and on which injury could occur
due to unexpected energization, startup or release of stored energy shall be deactivated. This
includes opening electrical circuits, closing and bleeding pressurized hydraulics and pneumatics,
blocking springs or counterweights and discharging capacitors (for example).
1. LOTO indicates that the energy source is Locked Out and that an Authorized Employee is
actively working on the machine, equipment, process, or circuit. LOTO is limited to one shift or
the amount of time the person is actively working on the system. If the job is not finished and
the system is not ready to be put back in use, the authorized person shall apply the Transition

must be followed:
a. Prepare for shutdown.

c. Isolate machine or equipment.
d. Apply lockout and tagout device.

3. Temporary removal of LOTO and re-energization of a machine or equipment may be
performed when power is needed for testing or positioning. When testing you must:
a. Ensure the machine is operationally intact.
b. Notify all Authorized or Affected Employees who are working on the equipment or
are in the area that the equipment is going to be tested and to move to a safe area.
c. Verify controls are in the "off" position.
d. Remove LOTO Locks and tags.
