True or False: For an existing electrical system, no safety-related design concepts can be implemented to eliminate or mitigate electrical hazards.

True or False: For an existing electrical system, no safety-related design concepts can be implemented to eliminate or mitigate electrical hazards.

• A. True
• B. False
• C. Only with a major overhaul
• D. Not specified

Answer: (B)

Even after an installation is in place, you can reduce or eliminate electrical hazards by applying safety-focused design concepts through retrofits and upgrades. Implementing safety controls isn’t limited to new systems; you can modify an existing setup to lower risk. Examples include enclosing or guarding exposed energized parts, adding barriers, improving grounding and fault protection (such as GFCIs/AFCIs or improved overcurrent protection), updating wiring, and using interlocks. Administrative measures like safer work procedures and training—along with proper labeling and lockout/tagout—also help mitigate hazards. This aligns with the hierarchy of controls: aim to eliminate or engineer out hazards first, then use administrative controls, and reserve PPE for remaining risk. These changes can be done without a complete overhaul, making it clear that safety-related design concepts are applicable to existing systems.
