Intent

Intent 1:

To limit the probability that internally illuminated exit signs will not operate properly [e.g. due to normal power failure], which could lead to the exit signs not being illuminated in an emergency situation, which could lead to exit locations not being readily identified, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
