The OSHA standards for construction and operation of electric utility systems are found in:

• A. Construction Industry Standard 1926 Subpart V
• B. OSHA's General Industry Standard 1910 Subpart R
• C. 29 CFR 1910 Subpart Q
• D. Construction Industry Standard 1900 Subpart A

Answer: (A)

The main concept is that electrical safety for construction work on electric utility systems is covered by the construction-specific OSHA standard, not the general industry rules. The correct rule is the Construction Industry Standard that corresponds to 1926 Subpart V, which is the part of OSHA’s construction regulations dedicated to electrical safety for power transmission and distribution work. This section focuses on the hazards you encounter when building, maintaining, or operating electric utility systems, including high-voltage work, live-line procedures, required training for qualified persons, personal protective equipment, guarding and clearance requirements, and procedures for de-energizing and testing circuits in a construction setting.

This is the best fit because it directly applies to construction activities on electric utility systems, whereas the other options pertain to different parts of OSHA regulations (such as general industry electrical requirements or topics outside the construction context), which do not govern construction-specific electrical safety for utility work.
