Operational Limits Compliance

DOE-STD-1039-93

requiring that the equipment be deenergized and inoperable. Lockout/tagout is applied after

equipment has been isolated from energy and hazardous material sources by placing danger

tags, or locks and tags, on the isolation devices to ensure that energy cannot be restored.

Because lockout/tagout changes the operational status of the affected equipment,

lockout/tagout activities should be approved by the operations supervisor. All personnel

should receive training on the requirements of the facility lockout/tagout program and their

individual responsibilities under the program. All personnel must understand that operation

or manipulation of equipment under lockout/tagout control is strictly forbidden. Additional

information concerning lockout/tagout requirements is contained in DOE Order 5480.19,

Chapter IX, "Lockouts and Tagouts," and in DOE-STD-1030-96, Guide to Good Practices

for Lockouts and Tagouts.

4.4 Operational Limits Compliance

Those facilities subject to technical safety requirements must establish administrative

controls to ensure proper adherence to operational limits (also known as limiting conditions

for operation). These operational limits are usually expressed as specific conditions (e.g.,

a redundant pump is not operable) requiring specific response actions (e.g., load reduction).

The operations supervisor should direct, or be aware of, all actions that are taken in

response to the operational limit requirements or actions to mitigate adverse consequences

to the facility. All appropriate personnel should be informed of the operational limit

requirements. All personnel having responsibility for actions under operational limits should

periodically review the conditions for operation and ensure that the appropriate actions are

performed.

Facilities must document compliance with operational limits. One method is to initiate a

tracking document or file each time a designated condition is encountered. The file should

include information from logs, alignment checklists, turnover checklists, or other

documentation to indicate the initial conditions and circumstances that resulted in restricting

operations. All actions taken in response to the operational limit requirements and other
