Occupancy Classification Under
NFPA 13
Examine the proposed facility and make recommendation on
the Occupancy Classification
Used to classify fuel loads and fire severity associated with
building operations
Light Hazard
Ordinary Hazards Group 1 and Group 2
Extra Hazard Group 1 and Group 2
Commodity Classifications Under
NFPA 13
The commodity classification is important in sprinkler system
design.
Adjustments are made to sprinkler system water demands to
ensure it can put out a fire involving the stored commodities.
Examine the proposed facility and make recommendation on
the Commodity Classification
Defines potential fire severity based upon the type, amount, and
arrangement of commodities
Commodity Classifications Under
NFPA 13
Class I: noncombustibles packaged directly on wooden pallets, single layer
cartons, or shrink wrapped
Class II: noncombustibles packaged
in slatted wooden crates,
corrugated cartons
Class III: wood, paper, natural fiber products
Class IV: Group A or Group B plastics
See the Commodity Classification document for definitions
NFPA 5000 Occupancy
Classifications
To classify a building under NFPA 5000:
Chapter 6 provides definitions of the different Occupancy Classifications
Assembly, Educational, Industrial, etc.
In addition to the occupancy classification, a facility can be further classified as:
Multiple occupancy: a building in which 2 or more classes of occupancies
exist
Mixed occupancy: a multiple occupancy in which the occupancies are
intermingled
Separated occupancy: an occupancy in which the occupancies are separated
by a fire rated barrier as required in NFPA 5000
Classifying Your Occupancy Under
NFPA 5000
Under NFPA 5000, the definition of an Industrial Occupancy
is an occupancy in which products are manufactured, or in
which processing, mixing, … or repair operations are
conducted.
Industrial Occupancies must meet Chapter 29 of the NFPA
5000 standards
Classifying Your Contents Under
NFPA 5000
Building contents can be classified as Low, Ordinary, and
High
High Hazards Contents can be classified as Level 1 through 5
All are defined in Chapter 6 of NFPA 5000
Your building will be using limited amounts of flammable liquids in closed
containers in the finishing area.
NFPA 5000, Chapter 34: Protection
Levels
Protection Levels 1 thru 5
If the quantities of hazardous contents exceeds the maximum
allowable quantities (MAQ’s) under the Code, then the building
construction must meet additional construction/protection
requirements
For example, if a quantities of Level 1 High Hazardous Contents
exceeds the maximum allowable quantity, then the facility must
meet Protection Level 1 requirements
Same for other Contents Classifications (Level 2 – 5)
If you don’t exceed MAQ’s, then follow Ordinary Hazard
requirements
Special Operations
NFPA 5000 identifies 66 special operations which require
additional building construction requirements from NFPA
standards outside of NFPA 5000.
For example, a special operation would be a spray booth which would fall
under NFPA 33: Standard for Spray Application Using Flammable and
Combustible Materials.
Using Chapter 29 of NFPA 5000
In addition to the requirements in Chapter 29, an industrial
occupancy must also meet the requirements of:
Chapter 7, 8, 13, 14, 31, 35, 36, 37, 38, 39, and 40
Portions of other Chapters may be required as cited in the
Chapter 29
ConstructionType Classifications
Examine the proposed facility and make a recommendation
on the following:
Construction Type Classification (NFPA 220 and NFPA 5000)
Type I: (Formerly Fire Resistive)
Type II: (Formerly Non-combustible)
Type III: (Formerly Ordinary Construction)
Type IV: (Formerly Heavy Timber)
Type V: (Formerly Wood Frame)
Mixed Construction
Dead Loads
Material, equipment, or components that are relatively
constant throughout the structure's life
Walls, floors, roofs, ceilings, stairways, built-in partitions,
finishes, cladding and other similarly incorporated
architectural and structural items, and fixed services
equipment
Live Loads
All the forces that are variable within the building’s normal
operation cycle
Moveable loads
Wind load
Snow load
Rain load
Earthquake load
Flood load
Case Study 2
Following NFPA 13, selection of the NFPA Building Type Classification (Provided in
Module)
Following NFPA 13, determination of Occupancy Classification and Commodity
Classifications (Provided in Module)
Following NFPA 5000, determination of Occupancy Classification and Contents
Classifications (Include Construction Type, Fire Ratings, Maximum stories, maximum
square footage)
Your facility will not exceed the maximum allowable quantities
In your case study, provide one example of each which could be expected for a building
of the type in the case study:
Live Loads, Dead Loads, Impact Loads, Static Loads, Axial Loads, Eccentric Loads
Selection of building materials for exterior, including foundation, structural supports,
exterior walls and roof
Must be selected according to your building type classification
