The arc flash boundary is related to minimizing exposure to arc flash hazards. This statement is:

Explanation:
The arc flash boundary exists to limit how much energy a person could be exposed to if an arc flash occurs. It is set at the distance where incident energy reaches a level that could cause significant injury, typically 1.2 cal/cm², which is associated with the potential for a second-degree burn. This boundary directly supports minimizing exposure because it tells you when you must wear appropriate PPE and when access should be restricted or controlled. In other words, staying outside the boundary reduces the likelihood of reaching harmful exposure, while entering it triggers protective measures to keep people safe.
