Occupancy Classifications and Loads
Determined by the way that the building or space is to be used
Address different hazardous situations or risk factors associated with each type of use
The projected occupant load is the most influential component in determining the occupancy classification.
Is considered to be the number of people that is assumed to safely occupy a space or building.
Interdependent and should be considered at the beginning of a project.
166
Occupancy Types

Determining Occupant Loads
Sets the number of occupants for which you must provide adequate exiting from a space or building.
Determined for each space or building by either using a given load factor, or by establishing a desired number of occupants.
These methods determine the number of people that must be used to be using the corridors, stairs, and exits in the event of a fire.
Based on the relationship between the size and use of the space or building
The code establishes a minimum level of safety by assigning a predetermined amount called the LOAD FACTOR; the amount of area or square feet required for each occupant based on:
1.Occupancy Classification
2.Specific use of the space
170
Accessory use area is
A space or room that is used in conjunction with the main occupancy, but does not exceed 10% of the floor area of the main occupancy
171
Incidental use area is:
An area that is incidental to the main occupancy and has the same classification as the nearest main occupancy but, by code, must be separated by a fire barrier
172
Combustible:
material that will ignite and burn
