10.9.2.2.2 DESIGN AND CONSTRUCTION

During design, special consideration should be given to installing interlocks and protective barriers.

Signs warning of the hazards should be posted to help prevent unsuspecting personnel from being

injured.

10.9.2.2.3 OPERATION AND MAINTENANCE

Appropriate safety procedures and training should be part of the process to qualify personnel. The

procedures should describe the methods used to promote safe work practices relating to work on

energized circuits in accordance with Sect. 2.1.2, "Considerations for Working on Energized

Systems and Equipment", Sect. 2.13, "Work Practices", and 29 CFR 1910.331-335.
