Our design is composed of occupancy sensors in large Locker rooms of a manufacturing plant but they apparently may not be enough to comply with the credit requirements.

We suggested to the client to add on/off switches to each locker room. As the lockers are large spaces (3250sf) the Client is afraid one employee could turn off the light leaving someone else in the dark: this does not comply with their safety policy.
Could you advise if we can make a case and stick with occupancy sensors?
