When are exit lights required?

When are exit lights required?

When are exit lights required?

(OP)
Are exit lights required for a data closet in an existing industrial occupancy?  The data closet will not normally be occupied  - actually it will only be accessed when someone needs to work on a rack mounted component which is seldom in this case.

RE: When are exit lights required?

Questions:

1) What is the area of the closet?
2) Is this in the US? If so the International Building Code (IBC) is most likely the applicable code.

I'm assuming that since it is a closet, the requirement for exit illumination in the IBC are probably not applicable. IBC section 1006.1 does require exit illumination in the means of egress. If it's a closet, its not a part of the egress path and illumination is not required.

If your speaking to exit signs IBC section 1011.1, exception 1 does not require them when the room only requires one exit or exit access opening.

RE: When are exit lights required?

It also depends how big is the "closet"? If it is a large room with lots of equipmnet in it making "aisles", some AHJ may deem an exit light necessary. Normally it will not be required.
