Which of the following is NOT an element of an Arc Flash Label?

An Arc Flash Label typically provides essential information regarding the potential hazards associated with electrical equipment, critical for ensuring safety during maintenance work. Among the elements commonly found on such labels are Incident Energy, PPE Recommendation, and Arc Flash Boundary, each serving a vital role in communicating the risks and required safety measures.

Incident Energy quantifies the energy available in an arc flash event, allowing workers to understand the severity of potential exposure. The PPE Recommendation indicates the appropriate personal protective equipment required to safeguard against electrical hazards, helping to ensure that personnel are properly equipped when working near energized equipment. The Arc Flash Boundary defines the distance from the potential arc flash source within which a worker could be exposed to dangerous energy levels, further guiding safe practices.

While the structure type may be relevant in other contexts, it is not a standard component of an Arc Flash Label. Labels focus specifically on the electrical hazard and safety requirements, rather than the physical characteristics of the construction or structure housing the equipment. Thus, selecting "Structure Type" as not being an element of an Arc Flash Label makes sense in the context of what information these labels are designed to convey.
