We have a long corridor and I check in NFPA 101, the travel distance to exit from corridor shall be 30 mtrs also there is a chance of the movement of Fire & Smoke.
We have given additional exit door to come up with the problem with the travel distace. But, to limit the smoke or Fire movement we have to provide the Doors in the corridor. I cannot find the in NFPA the Fire Rating of the door. I check NFPA 101 and 80. does any one have any suggestion
