Where Required?
Each model code, including the LSC, requires specific
occupancies to have exit devices based on occupant
loads related to exit doors. Table I compares these
relationships and differences between codes. Refer
to the actual code section for specific requirements.
Note: It is not uncommon for occupancies listed
in the table to be housed in buildings classified
as another occupancy, i.e. a lecture hall (assembly)
in a business occupancy used for educational purposes
at the college level.
