ABSTRACT
Energy sources should be isolated in a safe manner by locking them out, tagging them and testing the isolated energy source. The energy lockout, tag, and tryout procedures should be applicable for safely isolating all energy sources such as electrical, stored electrical, other stored energy, hydraulic, pneumatic, thermal, process gases, fluids, chemical, and mechanical sources of energy. The standard should cover all hazardous sources of energy, irrespective of the type and/or voltage. Energy sources include the following: distribution power lines, control and operation panels in power plants, switches, disconnects, cables, feeders, circuits, water pressure, air pressure, other stored energy, gravity, etc., and associated equipment and devices which are sources of stored energy. Managers, supervisors, and contractors are responsible for ensuring that suitably trained persons carry out inspections of lifting equipment at scheduled intervals and that the results are recorded on the relevant checklist.
