2. Lock-out / Tag-out (LO/TO). Purpose:To protect workers from the release of hazardous energy, and;To guard against the accidental start-up of equipment during service and maintenance.. 3. Energy Sources. Typical sources of energy that may need to be isolated, locked and tagged out include:Electrical (electric motors, batteries)Hydraulic (e.g. pressurized fluids in hoses/pipes)Pneumatic (e.g. pressurized air in hoses/pipes)Mechanical (e.g. gravity systems, or spring energy)Chemical (30021

8. 8 Testing a motor driven piece of equipment is done by bumping the start/stop switch to determine if motor is still energized. Whenever isolation block valve can not be locked out for some reason or if in the case of a block valve that is passing and it requires isolation at another point further back in the system personnel must ensure that any clean up of the equipment that is required done from the new point of isolation.

15. 15 Tags (cont’d) Design of Tags: Tags are to be standard across facility and different in design from other types of tags used for other purposes. Tags must be made of a suitable weather proof & when applicable heat resistant material. Tags should be written in a language understood by the workforce or may be bilingual. Tags should be filled out using a permanent marker. Must identify who put the tag, the date installed, the equipment isolated and the reason it is being isolated. Tags may be color coded to identify the discipline installing it. (e.g. Yellow Operations, blue Maintenance and red Electrical or Instrument Technicians)
