Hi and thanks for using JustAnswer.com. There will be 2 exits per floor. All areas must have direct unobstructed access to both exits. The fire stairway can be interior, or exterior. Self closing fire doors are required in stairways. The exits should be on opposing sides or ends of the building. 2 exits times 4 floors equals 8 exits.

Im sorry. I neede it explained like a math problem, ex: 100 X 200= 2000 X4= 8000 divided by ? to get the # XXXXX rooms. Can you show it to me like that?
Customer: replied 5 years ago.
I am still waiting for a resonse to my last reply. I needed the answer to my question in the form of a math answer with the calculation.
Expert:  Stephen Cutler replied 5 years ago.
The number of rooms times 2 ways out each(access requirements), plus 2 common exits each floor times 4 floors. The number of rooms are the controlling factor and are not derived from the square footage.
Expert:  Stephen Cutler replied 5 years ago.
I meant number of rooms a controlling factor, which has not been provided, and so is the sticking point in proceeding further with the calculation.

Can I get someone else to help me with my question?
Expert:  Stephen Cutler replied 5 years ago.
You sure can. It looks like this is not a firecode question, but rather some kind of homework question so I sent your question to Homework category. You might want to rephrase the question eliminating references to firecode exits.
