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

Page 3: Occupancy Classification Under NFPA 13 Examine the proposed facility and make recommendation on the Occupancy Classification Used to classify fuel loads

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 productsClass 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 ClassificationsAssembly, 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 existMixed occupancy: a multiple occupancy in which the

occupancies are intermingledSeparated occupancy: an occupancy in which the

occupancies are separated by a fire rated barrier as required in NFPA 5000

Page 5: Occupancy Classification Under NFPA 13 Examine the proposed facility and make recommendation on the Occupancy Classification Used to classify fuel loads

Classifying Your Occupancy Under NFPA 5000Under 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

Page 6: Occupancy Classification Under NFPA 13 Examine the proposed facility and make recommendation on the Occupancy Classification Used to classify fuel loads

Classifying Your Contents Under NFPA 5000Building contents can be classified as Low,

Ordinary, and HighHigh Hazards Contents can be classified as

Level 1 through 5All are defined in Chapter 6 of NFPA 5000Your building will be using limited amounts of

flammable liquids in closed containers in the finishing area.

NFPA 5000, Chapter 34: Protection LevelsProtection 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 OperationsNFPA 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 5000In 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 40Portions of other Chapters may be required

as cited in the Chapter 29

ConstructionType ClassificationsExamine 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 LoadsMaterial, 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 LoadsAll the forces that are variable within the

building’s normal operation cycleMoveable loadsWind 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
