NFPA 13 Occupancy Hazard Classifications

Light Hazard Occupancies
- Include animal shelters, churches, clubs, and nursing homes.
- Characterized by low combustibility and minimal combustible materials.
- Suitable for spaces like offices, educational facilities, and unused attics.
- Museums and libraries (excluding large stack rooms) also fall under this category.
Ordinary Hazard (Group 1) Occupancies
- Defined by moderate combustibility with stockpiles of combustibles not exceeding 8 ft (2.4 m).
- Examples include garages, bakeries, and automotive showrooms.
- Represent moderate heat release rates in fire scenarios.
Ordinary Hazard (Group 2) Occupancies
- Higher combustibility with stockpiles not exceeding 12 ft (3.66 m) for moderate rates and 8 ft (2.4 m) for high rates of heat release.
- Covers facilities like agricultural buildings, chemical plants, and textile manufacturing.
- Characterized by moderate to substantial amounts of combustibles.
Extra Hazard (Group 1) Occupancies
- High levels of combustibility and presence of dust or lint, increasing fire risks.
- Includes areas like aircraft hangars, metal extruding, and rubber processing.
- Fires expected to develop rapidly with high heat release.
Extra Hazard (Group 2) Occupancies
- Defined by substantial amounts of flammable liquids or extensive shielding of combustibles.
- Includes operations like solvent cleaning, plastics manufacturing, and varnish dipping.
- Occupancies often face rapid evaporation and ignition risks due to high temperatures.
Significance of Classification
- Each classification informs fire protection and sprinkler design standards as per NFPA guidelines.
- Ensures appropriate safety measures are in place based on the nature of the occupancy and materials present.

This quiz covers the classifications of occupancy hazards as per NFPA 13 standards. Flashcards include various types of facilities and their corresponding hazard classifications, mainly focusing on light hazards. Test your knowledge on these important safety classifications.
