I am doing a remodel in a fairly small commercial building. My question is what are the requirements for any type of night lights, meaning any lights that need to stay on all the time in any certain locations,if any. The building will have a capacity of about 100 people. What NFPA code book should i reference to find the answer and have handy to use in the future. Also for a flourescent light using an emergency ballast, would a black light(bulb) be sufficient? again where can i find answers to these questions in the future, as opposed to calling the fire inspector on every question? thanks so much, justin
