Hazardous Energy Control Program
1. Application of Lockout Control
Each department chair/director/manager shall be responsible for developing
written lockout procedures for the machines and equipment under their control
or ownership, which require such procedures. The written procedure shall meet all of the
requirements of MIOSHA Part 85 c(4)(ii).
Cord and plug connected electrical
equipment, for which exposure to the hazards of unexpected energization or startup
to the equipment is controlled by the unplugging of the equipment from the energy
source, is exempt from the written procedure requirement provided that the unplugged
cord is under the exclusive control (the plug must be within sight or three feet
of the employee at all times during the work) of the employee(s) conducting the
service or maintenance activities. A written procedure is also not required when a
piece of equipment has only a single source of energy which can be readily identified
and isolated provided that: when locked out with a single locking device, the equipment
will be completely de-energized and deactivated, the lockout device is in the exclusive
control of the authorized employee performing the work, the work does not create a hazard
for other employees, and MTU has had no accidents involving unexpected energization or
activation of the equipment.
- Preparation for Shutdown - Personal safety locks and keys will be kept by
each individual operator, mechanic, electrician. Supervisors will also have their
own locks and keys. Authorized employees shall review the written lockout procedure
to have complete understanding of the type(s) and magnitude of the energy, the
hazards of the energy to be controlled, and the methods or means to control the
- Notification of Employees - Affected employees shall be notified by the authorized
employees that the machine or equipment is going to be locked out.
- Machine or Equipment Shutdown - The machine or equipment shall be turned
off or shut down using the energy control procedures established for the machine
- Machine or Equipment Isolation - All energy isolating controls that are needed
to control the energy of the machine or equipment shall be physically located
and operated in such a manner as to isolate the machine or equipment from the
energy sources (e.g., steam, pneumatic, hydraulic). A Zero Energy State must be
proven. If the valves do not permit the use of a standard lockout, another method
such as wire cable and lock can be used. When gravity is a source of hazardous energy
the affected component must be physically blocked to isolate the hazard.
- Lockout Device Application - The multiple lock adapter and lock shall be
affixed in such a manner as to hold the energy isolation devices in a safe or
- Notification of Affected Personnel - Affected employees shall be notified
by the authorized employees that the machine or equipment is locked out. In addition
to verbal notification, a sign indicating a power lockout condition will be placed
near the machine/equipment controls.
- Verification of Isolation - Prior to starting work on a machine or equipment
that has been locked out, each authorized employee involved shall verify that
the isolation and de-energization of the machine or equipment have been accomplished
by testing the effectiveness of the lockout by attempting to cycle the machine
or start the equipment at the motor control center panel or start/stop switch.
Each authorized employee will notify other authorized and affected personnel in
the area that they are going to attempt to cycle the machine or equipment prior
to doing so and shall ensure that personnel are free and clear of the machine
or equipment prior to operating the controls.
If the controls activate the machine or equipment or cause any machine or equipment
movement, each authorized employee will begin again at step A, Preparation for
If there is the possibility of re-accumulation of stored energy to a hazardous
level, verification or isolation shall be continued until the servicing or maintenance
is completed, or until the possibility of re-accumulation no longer exists. Stored
or potential energy will be relieved, restrained, or otherwise made safe.
- Begin Work Activity - Work activity will begin once each authorized employee
involved has verified that the current control of hazardous energy sources has
