What is the purpose of the flash protection boundary in NFPA 70 Live Work?

To determine appropriate escape routes
To determine when PPE is required
To limit access to hazardous areas
To define work hours for electricians

The correct answer is: To determine when PPE is required

The purpose of the flash protection boundary as outlined in NFPA 70, particularly regarding live work, is fundamentally tied to safety practices in electrical work. This boundary defines the distance from an energized electrical source within which individuals are at risk of injury from an electrical arc flash. By establishing this boundary, it helps determine when personal protective equipment (PPE) is necessary. When workers are within this boundary, they must wear appropriate PPE to protect against potential arc flash hazards. Thus, understanding where this boundary lies directly informs the necessity of wearing specified levels of PPE to ensure safety, making this answer relevant to the operational practices and safety protocols that workers must follow in live electrical environments. The other options, while they touch on important aspects of workplace safety, do not relate directly to the specific function of the flash protection boundary in NFPA 70. Escape routes, restricting access, and defining work hours are all important for various safety considerations but do not pertain to the immediate electrical hazard assessments that the flash protection boundary provides.
