The EE/EL maintenance job guides [-2JG-( )-( ) T.O.s] SHOULD expliciity state safety requirements for each task.
NOTE: most F-15 circuit breakers [CBs] are push-on (reset) and tripped-out (off) [push/pull style]. In this case the CBs are typically "collared" , IE: secured with a tye-wrap around the tripped-out pole, to prevent accidental reset [pushed-back-in]... without breaking the tye-wrap. I believe USAF maintenance regs also describe safety procedures in terms of actions required by mechanics, such as: when to disconnect/tag batteries, use of "warning signs"; and annotating aircraft records with specific actions taken thqat leave it in a "red X or red diagonal" status.
