What about USA codes? Are not there any regulations directives etc to which we can access freely ? I think NEC might include these codes perhaps true? I wonder also what is the content of NFPA , only fire protection ? if So it would contain the parts related to fire protection true? I wonder if there is any special codes issued by the government about only this issue , Pls let me know about the codes to which I can have recourse whenever I need while planning a say hospital project...
