6.2.1 General Practices l
a.
Clearances wtll be prepared using only controlled drawings or other i
controlled documents as references. Recommended isolation points I
specified by personnel on the clearance request will, in all cases, be venfied using convolled documents.
b.
Only miniature tags will be used on control panels to prevent the I
[
obscuring of plant status indications, contmls, switches and labels.
l c.
Before a elearance is issued for a component, system or electrical circuit, all sources of energy that may cause personnel injury or i
ec uipment damage shall be isolated from the work area. For example, I
w wn isolating a puun motor, the pump suction and discharge v>Jves I
should be shut and tagged to prevent possible rotation due to fluid i
i Gow.
6.2.2 Piping Sysums Practices a.
Sysems, ponions of systems, and components that nonnally operate i.t temperatures and pressures above ambient will be vented and,if necessary for the performance of work, drained before a clearnace to work is issued. Whenever possible, an atmospheric drain and/or vent between the oc uipment to be worked and sources of pressure to the equipment shal be tagd in the open position to depressurias the equipment.a.n.d to wea==~ta= thermal expansion or.c..ontraccon.
