Egress Lighting

[Little Bill]

Does a small church, less than 100 people, require Egress and emergency lighting?

Can EM lights be on a circuit with something else?

Also, does it need exit signs?

 

[Little Bill]

Another question..........
If the exist signs also have EM lighting, will that suffice for EM lighting?

This is really a local fire marshal call, but I have yet to see a public space where exit lights aren't required at all egress doors. Whether the EM lights on the exits will suffice depends on the square footage of the rooms covered. Bathrooms and hallways usually need at least one EM light.

Also, the exit and EM lights should be on the local lighting circuit. There are exceptions when multiple circuits serve a space

You go to the adopted building code for that project and look for the section for mean of egress illumination and see if your occupancy group applies.
For example, Churches are usually Occupancy Group A3. You can look at the IBC Section 1008 for mean of egress illumination and exits signs in IBC Section 1013.
To makes head or tails of the Exception in 1008 for Aisle Accessways, you will need to look at Chapter 2 for definitions and see what "aisle accessways" mean, then definition of "exit access".

The readers digest answer is, that egress lighting is required and could be part of an exit sign, but isn't needed throughout the facility.

Egress lighting is required throughout the facility with a few exceptions, but emergency egress lighting is not required everywhere. Emergency egress lighting is typically required where two or more exits are required (typically 50 occupants), or where otherwise specifically required by a code such as the IBC or NFPA 101.
