Transcript Module 2 Case Study - Indiana University of Pennsylvania

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

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
