Regulation Information  Safety–Related Work Practices
            Protection of Employees
            The employer must not permit an employee to work near any part of an 
            electric power circuit that the employee could contact in the course 
            of work, unless the employee is protected against shock by 
            deenergizing the circuit and grounding it or by guarding it 
            effectively by insulation or other means.
            Where the exact location of underground electric powerlines is 
            unknown, employees using jack hammers or hand tools which may 
            contact a line must be provided with insulated protective gloves.
            Even before work is begun, the employer must determine by inquiry, 
            observation, or instruments where any part of an exposed or 
            concealed energized electric power circuit is located. This is 
            necessary because a person, tool or machine could come into physical 
            or electrical contact with the electric power circuit.
            The employer is required to advise employees of the location of such 
            lines, the hazards involved, and protective measures to be taken as 
            well as to post and maintain proper warning signs.
            Passageways and Open Spaces
            The employer must provide barriers or other means of guarding to 
            ensure that workspace for electrical equipment will not be used as a 
            passageway during the time when energized parts of electrical 
            equipment are exposed. Walkways and similar working spaces must be 
            kept clear of electric cords.
            Other standards cover load ratings, fuses, cords, and cables.
            Lockout and Tagging of Circuits
            Tags must be placed on controls that are to be deactivated during 
            the course of work on energized or deenergized equipment or 
            circuits. Equipment or circuits that are deenergized must be 
            rendered inoperative and have tags attached at all points where such 
            equipment or circuits can be energized.
