Study Notes
Building Code Fundamentals
- The fundamental consideration for the building code is to provide a safe environment for occupants.
- Occupancy groups are determined by the use of a facility, and each group has specific requirements for allowable area and height of a building, means of egress, and type of construction.
Occupancy Classification
- The ultimate judge of occupancy classification is the building official.
- Facilities are assigned to an occupancy group based on the use of the facility.
- Atypical occupancies are classified based on the predominant use of the facility.
- Uses are separated in the building code into different occupancy groups, each with specific requirements.
Control Areas
- The control area concept is used to separate hazardous occupancies from non-hazardous occupancies.
- The primary consideration for establishing control areas is the hazard level of the occupancy.
- Control areas must be separated from one another by fire-resistant construction.
- The control area concept reinforces the importance of separating hazardous occupancies from non-hazardous occupancies.
Specific Occupancy Groups
- Group B occupancies include offices, mercantile establishments, and food-processing facilities.
- Group E occupancies include educational facilities for six or more people up to the 12th grade.
- Group F occupancies include factories and warehouses, with F-1 being moderate-hazard and F-2 being low-hazard.
- Group H occupancies include high-hazard facilities, with H-1 through H-4 being classified based on the nature of the use and the quantity and nature of hazardous materials.
Other Key Concepts
- Maximum allowable quantities (MAQ) pertain to occupancy classification related to quantities and do not waive compliance with other code provisions.
- Chapter 4 must be read in concert with other chapters to determine all applicable code requirements for separation of control areas.
- Religious classrooms and auditoriums that are accessory to churches and have fewer than 50 occupants are considered A-3 occupancies.
