SECTION 12

CONTROL OF HAZARDOUS ENERGY
(LOCKOUT/TAGOUT)
12.A GENERAL

12.A.01 Before an employee performs any servicing or
maintenance on a system where the unexpected energizing, start
up, or release of kinetic or stored energy could occur and cause
injury or damage, the system shall be isolated in accordance with
the requirements of this Section. Personnel and resources shall
not be considered protected until hazardous energy control
procedures have been implemented. > USACE employees shall
comply with ER 385-1-31.

12.A.02 Coordination.

a. All control activities shall be coordinated with and approved
by the GDA.

b. When Contractors are planning the use of hazardous
energy control procedures, they shall submit their hazardous
energy control plan to the GDA for acceptance. Implementation
of hazardous energy control procedures shall not be initiated
until the hazardous energy control plan has been accepted by
the GDA. > See 12.A.07

c. The GDA and the Contractor designated authority shall fully
coordinate their control activities with one another throughout
the planning and implementation of these activities. Each shall
inform the other of their energy control procedures, ensure that
their own personnel understand and comply with rules and
restrictions of their procedures, and ensure that their employees
affected by the hazardous energy control activity are notified
when the procedural steps outlined in the hazardous energy
control plan are to be initiated.

12.A.03 A preparatory inspection with the GDA and Contractor
personnel shall be conducted to ensure that all affected employees
understand the energy hazards and the procedures for their control.

a. When energy control procedures affect both USACE and
Contractor(s), all USACE and Contractor affected employees
will participate in the preparatory inspection.

b. The preparatory meeting shall be documented. The time
and date of the meeting, the subject matter discussed, and the
name of all employees in attendance shall be recorded.

12.A.04 Lockout and tagout shall be performed only by authorized
employees.

12.A.05 All employees affected by the lockout or tagout shall be
notified, before and upon completion of, the application and
removal of lockout or tagout devices.

12.A.06 Lockout and tagout devices.

a. Systems with energy isolating devices that are capable of
being locked out shall use locking devices to control hazardous
energy unless the GDA or the Contractor designated authority
has demonstrated and documented all of the following:

(1) The use of locking devices would entail burdens that
exceed any advantage to the use of lockout over the use of
tagout devices,

(2) The use of tagout devices will provide full personnel
protection (as defined in Appendix Q), and

(3) All affected employees can and will be informed that
tagout is being used in lieu of lockout.
EM 385-1-1

251
b. If an energy isolating device is not capable of being locked
out, the hazardous energy control procedures shall use tagout
providing full personnel protection, as follows:

(1) All tagout requirements of this regulation and of the
hazardous energy control procedures shall be complied with;

(2) The tagout device shall be attached to the same
location, if possible, that the lockout device would have been
attached. If this is not possible then the tag shall be
attached as close as safely possible to the device and in a
position that will be immediately obvious to anyone
attempting to operate the device; and

(3) Additional means (e.g., placement of the tag in a manner
that inhibits operation of the energy isolating device, removal
of an isolating circuit mechanism, blocking of a control
switch, opening of an extra disconnecting device, removal of
a valve handle to reduce the likelihood of inadvertent
energization, etc.) shall be employed to provide a level of
protection commensurate to that provided by a lockout
device.

12.A.07 Hazardous energy control plan.

a. Hazardous energy control procedures shall be developed in
a hazardous energy control plan.

b. The plan shall clearly and specifically outline the scope,
purpose, authorization, rules, and techniques to be used for the
control of hazardous energy, including, but not limited to, the
following:

(1) A statement of the intended use of the procedure;

(2) Means of coordinating and communicating hazardous
energy control activities;
EM 385-1-1

252
(3) Procedural steps and responsibilities for shutting down,
isolating, blocking, and securing systems to control
hazardous energy;

(4) Procedural steps and responsibilities for the placement,
removal, and transfer of lockout and tagout devices;

(5) Procedural steps and responsibilities for placing and
tagging, and moving or removing and untagging, protective
grounds;

(6) Requirements for testing the system to verify the
effectiveness of isolation and lockout and tagout devices;

(7) A description of any emergencies that may occur during
system lockout or tagout and procedures for safely
responding to those emergencies;

(8) Requirements when authority for removal of hazardous
energy control devices must be transferred from the
authorized employee to another individual, and the names of
the individuals qualified for receiving such transfer; and

(9) The means to enforce compliance with the procedures.

12.B TRAINING

12.B.01 Training shall be provided to ensure tha t the purpose and
function of the hazardous energy control procedures are
understood by employees and that employees possess the
knowledge and skills required for the safe application, usage, and
removal of energy controls.

a. Each authorized employee sha ll receive training in the
recognition of hazardous energy sources, the type and
magnitude of energy available in the workplace, and the
methods and means for energy isolation and control.

253
b. Each affected employee shall be instructed in the purpose
and use of the energy control procedures.

c. All incidental personnel shall be informed of the procedures
and prohibitions relating to restarting or reenergizing systems
which are locked or tagged out.

d. When tagout systems are used, employees shall be trained
in the limitations of tags.

12.B.02 Employees shall be retrained in hazardous energy control
procedures whenever:

a. There is a change in their job assignments, a change in
systems or processes that present a new energy control hazard,
or a change in energy control procedures; or

b. Periodic inspection reveals, or there is reason to suspect the
presence of, inadequacies in or deviations from the employee's
knowledge or use of energy control procedures.

12.B.03 The supervisor shall certify and document all training and
retraining. Certification shall contain such information as the
names of employees trained; the time, date, and location of
training; the name of the trainer, etc.


12.C PERIODIC INSPECTIONS

12.C.01 Daily inspections shall be conducted to ensure that all
requirements of the hazardous energy control procedures are being
followed.

12.C.02 Inspections shall be documented and shall specify the
system (location) where the energy control procedures were
inspected, the date of the inspection, the names of employees
performing and included in the inspections, and any deficiencies in
complying with the hazardous energy control procedures.
