Study Notes

Occupancy Classification

Classifications assigned to structures, based on intended use to ensure safety and code compliance.
Divided into categories reflecting risk levels and specific usage scenarios.

Occupant Load

Total number of individuals allowed to occupy a building at any given time.

Risk Factors and Hazards

Influenced by the number of occupants, their mobility, alertness, familiarity, and potential fire spread.

Assembly Occupancy

Spaces designed for gatherings (over 50 individuals).
Features include low lighting, limited awareness, and risk of panic.

Specific Assembly Occupancies

A-1: Theaters (motion picture, concerts, etc.) with fixed seating and low lighting.
A-2: Food venues (restaurants, nightclubs) with dynamic furniture layouts and late hours.
A-3: Worship and recreation spaces (museums, gymnasiums) that account for moderate loads.
A-4: Venues for indoor sporting events (arenas, rinks) with defined seating.
A-5: Outdoor venues for activities (stadiums, amusement parks).

Business and Educational Occupancies

Business: Facilities for business transactions (banks, offices, post offices).
Educational: Buildings for educational purposes up to 12th grade; capacities between 6-500.

Specialized Occupancies

Factory: Spaces for product manufacturing and assembly (e.g., textiles, machinery).
Hazardous: Facilities dealing with hazardous materials (e.g., fuel plants, ammunition storage).
Institutional: Care facilities for occupants requiring supervision (e.g., hospitals, jails).

Types of Institutional Occupancies

I-1: Supervised care facilities (e.g., group homes) with around-the-clock supervision.
I-2: Health care facilities (e.g., nursing homes) requiring surveillance for vulnerable individuals.
I-3: Detainment facilities requiring monitoring for safety and security.
I-4: Daycare facilities providing temporary care.

Residential Occupancies

General classification for buildings providing sleeping accommodations.
Specific types include:
- R-1: Transient residences (hotels, motels) for less than 30 days.
- R-2: Multi-dwelling units (apartments, dormitories).
- R-3: Permanent residences (single-family homes).
- R-4: Assisted living facilities catering to a limited number of residents.

Storage Occupancy

Structures used for storing various products with minimal occupancy.
Examples include warehouses and cold storage facilities.

Utility and Miscellaneous Occupancy

Non-standard buildings not fitting other categories (e.g., barns, parking garages, mobile homes).

Mixed Occupancy Types

Buildings such as hotels or malls may encompass multiple occupancy classifications.

Load Factor

Calculation based on occupant load and floor area to determine maximum allowable occupants.

Construction Types

Five categories determined by fire-resistive capabilities:
- Type I: Fire-resistive materials (steel, concrete).
- Type II: Non-combustible materials but allows some combustion.
- Type III: Mix of combustible and non-combustible materials.
- Type IV: Heavy timber structures.
- Type V: Wood structures, including residential buildings.

Fire Safety Elements

Fire Wall: Constructed to limit fire spread, extending from foundation to roof.
Horizontal Assemblies: Serve as fire barriers extending horizontally between walls.
