Which OSHA electrical-safety standards apply to HVAC technicians working on energized equipment?

• A. OSHA 29 CFR 1910 electrical safety-related work practices; lockout/tagout per 29 CFR 1910.147; use proper test instruments and clearances.
• B. OSHA 29 CFR 1926 safety standards for construction.
• C. NFPA 70 electrical code alone.
• D. OSHA 29 CFR 1910.1200 hazard communication requirements only.

Answer: (D)

The key idea is understanding which OSHA rules govern how you work safely around live electrical parts and how you control energy sources. For HVAC technicians handling energized equipment, the relevant standards cover electrical-safety-related work practices and energy isolation. This includes the OSHA provisions that specify how to perform tasks near exposed energized parts and the lockout/tagout requirements that ensure circuits are de-energized before servicing. It also includes guidance on using the right test instruments and maintaining proper clearances to avoid contact with live components. NFPA 70 (the electrical code) is a wiring standard, not an OSHA rule by itself, and hazard communication focuses on chemical hazards rather than electrical hazards. Construction standards apply primarily to construction sites, not routine industrial maintenance. So, the standards that apply are OSHA’s electrical safety-related work practices along with lockout/tagout and the proper use of test instruments and clearances.
