OSHA 10 Hour Construction Program Practice Test

Most electrical safety guidelines in construction are based on which standard?

1. The International Building Code

2. The National Electric Code

3. The OSHA Standards for Workplaces

4. The ANSI Z359 Fall Protection Code

The correct answer is: The National Electric Code

The correct answer is based on the National Electric Code (NEC), which serves as a comprehensive set of guidelines specifically for electrical installations and safety in the United States. Developed by the National Fire Protection Association, the NEC outlines standards for safe electrical design, installation, and inspection to prevent hazards such as electrocution, electrical fires, and equipment malfunction. In the context of construction, following the NEC is crucial because it ensures that electrical systems are not only safe for workers but also functional and efficient. Many of the specific provisions in the code address proper grounding, wiring methods, and protection against electrical overloads, which are vital for maintaining a safe worksite. The International Building Code provides broader provisions for various aspects of building safety but is not focused specifically on electrical systems. OSHA standards are crucial for overall workplace safety but do not provide the detailed guidelines specific to electrical installations. Similarly, the ANSI Z359 Fall Protection Code is concerned with fall protection measures and does not cover electrical safety, making it irrelevant to this context. Thus, the National Electric Code stands out as the foundational standard that specifically governs electrical safety in construction settings.
