The design area is a theoretical area of the building representing the worst case area where a fire could occur.After determining the hazard classification, a design area and density can be determined by referencing tables in NFPA 13 Increasing density in millimeters per minute per square meter Increasing area in square feet Increasing area in square meter Increasing density in gallons per minute per square foot.NFPA 13FIGURE 11.2.3.1.1 Density/Area Curves Manufactured home or modular building assemblies (where finished enclosure is present and has combustible interiors).Textile picking, opening, blending, garnetting, or carding, combining of cotton, synthetics, wool shoddy, or burlap Įxtra Hazard Occupancies (Group 2) A.5.4.2 Extra hazard occupancies (Group 2) include occupancies having uses and conditions similar to the following:.Rubber reclaiming, compounding, drying, milling, vulcanizing.Plywood and particle board manufacturing.Aircraft hangars (except as governed by NFPA 409, Standard on Aircraft Hangars).Racetrack stable/kennel areas, including those stable/kennel areas, barns, and associated buildings at state, county, and local fairgrounds Įxtra Hazard Occupancies (Group 1) A.5.4.1 Extra hazard occupancies (Group 1) include occupancies having uses and conditions similar to the following:.Where utilized for storage, exterior loading docks and all interior loading docks should be protected based upon the actual occupancy, the materials handled on the dock, as if the materials were actually stored in that configuration. Exterior loading docks only utilized for loading and unloading should be classified as OH2.

Ordinary Hazard Occupancies (Group 2) A.5.3.2 Ordinary hazard occupancies (Group 2) include occupancies having uses and conditions similar to the following: Glass and glass products manufacturing.Dairy products manufacturing and processing.Ordinary Hazard Occupancy (Group 1) A.5.3.1 Ordinary hazard occupancies (Group 1) include occupancies having uses and conditions similar to the following:

Theaters and auditoriums, excluding stages and prosceniums.

Similarly, library stack areas, which are more akin to shelf storage or record storage, as defined in NFPA 232, Standard for the Protection of Records, should be considered to be ordinary hazard occupancies. can be considered to be light hazard occupancies. Typical library bookshelves of approximately 8 ft in height, containing books stored vertically on end, held in place in close association with each other, with aisles wider than 30 in.

It is not the committee’s intent to automatically equate library bookshelves with ordinary hazard occupancies or with library stacks.

Hospitals, including animal hospitals and veterinary facilities.

Eaves and overhangs, if of combustible construction with no combustibles beneath.

Usually buildings are classified as light hazard, ordinary hazard group 1, ordinary hazard group 2, extra hazard group 1, or extra hazard group 2.

First, the building use and building contents are analyzed to determine the level of fire hazard.

Most sprinkler systems installed today are designed using an area and density approach.
