Instrumentation, Controls and Support Equipment for SACs

DOE-STD-1186-2004

Specific AC are implemented using detailed administrative procedures, training of personnel,

and uniquely identifiable tags.

DOE O 5480.19 provides the following specific guidance on the use of Locks and Tags:

"Locks and Tags should be used on those components that require special

administrative control for safety or other reasons. Locks and Tags provide some

security that a component will be operated only by authorized facility personnel

performing required evolutions in a controlled fashion. Additionally, Locks and Tags

should alert the operator of the importance of the component and remind him/her that

special controls over repositioning are to be maintained. In this respect, all personnel

should receive training regarding their responsibilities concerning the manipulation of

locked or tagged controls."

A Tagout program meeting the guidelines in DOE O 5480.19 includes the placement of a

Tagout device on an energy-isolating device, in accordance with an established procedure, to

indicate that the energy-operating device and the equipment being controlled many not be

operated until the Tagout device is removed. Similarly, a Lockout program meeting the

guidelines in DOE O 5480.19 includes the placement of a Lockout device (e.g., a lock, or hasp

with a lock in place) on an energy isolating device in accordance with an established procedure

ensuring that the energy-isolating device and the equipment being controlled cannot be

operated until the Lockout device is removed. An effective Lockout/Tagout program should be

developed by each facility and should include detailed administrative procedures, training of

personnel, and uniquely identifiable tags. The program should also exercise appropriate control

over Lockout/Tagout preparation, approval, placement, and removal; provide for adequate

documentation; and be consistent with the requirements of 29 CFR 1910.

3.3

Instrumentation, Controls and Support Equipment for SACs

Operators often must rely on effective instrumentation and controls and support equipment to

implement SACs. For this reason, instrumentation and controls and equipment that support an

SAC should meet performance requirements consistent with the importance of the safety

function of the Specific AC.
