In NFPA 70E 130.2(2) it states that and Electrically Safety Work Condition must be established if "The employee interacts with equipment where conductors or circuit parts are not exposed but an increased likelihood of injury from an exposure to an arc flash hazard exists."
What is meant by the phrase "increased likelihood of injury"?
- Should this phrase be interpreted as - (1) an arc flash has occurred, what conditions would cause an increased likelihood of injury (e.g. confined space, fall from working at heights, flammable chemicals in area, proximity to other exposed energized parts, in traffic corridor, long emergency response time, unguarded spinning machinery in area...)?
- Or should this be interpreted to mean (2) look at NFPA 70E Table 130.5(C) to see if an arc flash has a "likelihood of occurrence"?
I read it as what I list above after (1), but this post - How to determine if electrical work is justified to be performed while energized - seems to interpret it as what I list above after (2).
