Lock Out/Tag Out

In the first place locking out the run button is a NO-NO  - Locking out the control circuit is NOT AN ACCEPTABLE METHOD.

MUST DEENERGIZE AND ISOLATE THE POWER CIRCUIT BY LOCKING OUT THE BRANCH CIRCUIT MAIN DISCONNECT SWITCH OR CIRCUIT BREAKER IN THE OFF POSITION. (If there is a disconnect sw. by the machine to facilitate maintenance work, it can be used to lock out)

EACH INDIVIDUAL WORKING ON THE MACHINE/DEVICE SHALL PUT HIS OWN LOCK.

DOUBLE CHECK THAT THE UNIT IS indeed deenergized before starting work.

Notes:
Check written LOTO procedure of the facility where work is being done, but one can always insist on and use one's  won lock.

Refer to NFPA 70 (NEC), NFPA 70E etc.

All technicians working with m/c and devices that utilize Kinetic and/or Potential energy (Electrical, Mechanical, Hydraulic, Pneumatic, spring energy etc )must be familiar with the equip. and study how to completely isolate all energy from that equipment they are working on.

Working on energized devices is a different ball game altogether, and not addressed here.

Thanks, Whaldas, this all makes sense. These procedures would certainly have prevented the problem addressed in this posting.
