Which Subpart of the CFR applies to the construction of electric power transmission and distribution lines and equipment?

The correct answer is Subpart V, which specifically addresses the safety requirements for the construction and maintenance of electric power transmission and distribution lines and related equipment. This subpart outlines the guidelines and standards that must be followed to ensure the safe installation and operation of these electrical systems. It focuses on mitigating hazards associated with electric power lines and ensures that workers are protected while performing tasks related to the construction and maintenance of such infrastructure.

Subparts C and J cover other areas of occupational safety and health, such as general safety and de-energization requirements, but they do not specifically address the electrical transmission and distribution systems in the same detailed manner as Subpart V. Subpart A deals with general provisions and does not cover the specific requirements for electric power transmission and distribution. Therefore, Subpart V is the most relevant and comprehensive section regarding the safety of electric power construction activities.
