When working on a PV system, important safety precautions should be followed including ___.

• A. All of These
• B. Using proper testing equipment rated for over 1,500 DC
• C. Employing OSHA fall protection standards
• D. Wearing appropriate PPE

Answer: (D)

Wearing appropriate PPE is the primary safety step because it provides a universal, immediate barrier against a range of hazards you’ll encounter on PV work. Electric shocks, arc flash, burns, and cuts can affect any task, so having arc-rated clothing, insulated gloves, eye/face protection, a hard hat, and other needed PPE is the baseline protection you should always have in place before starting. This aligns with standards that emphasize personal protection as a core requirement for electrical work. The other precautions are important, but they depend on the specific task or site conditions. Using testing equipment rated for the voltages you’re dealing with matters when you’re measuring or troubleshooting; fall protection standards apply only when you’re working at heights. Since PPE is applicable to nearly every job and directly reduces injury risk in all scenarios, it stands out as the essential precaution in this context.
