Battery-powered emergency lighting must be provided for Level 1 and 2 Emergency Power Supply (EPS) locations. Units that are located outdoors in enclosures that do not require walk-in access are not required to have battery-powered emergency lighting.

What would qualify as "walk-in access"? Our Generators are located outdoors in enclosures with large doors on the sides to allow for maintenance access. There are no steps or internal walkways/catwalks. My assessment is that they do not require battery-powered emergency lighting, would you agree?
