Final answer:
There should be two exits from a mezzanine if the occupant load is 50 or more, or if the mezzanine exceeds 2,000 square feet.
Step-by-step explanation:
In accordance with building codes, a mezzanine typically requires two exits when certain conditions are met. The International Building Code (IBC) states that two exits are required for mezzanines with an occupant load of 50 or more, or when the mezzanine level exceeds 2,000 square feet. This requirement ensures that there are enough means of egress to safely evacuate people in case of an emergency.
For example, if a mezzanine has an occupant load of 70, it would require two exits. However, if it has an occupant load of 30, only one exit would be required.
