1.6 PHILOSOPHY

Our work to verify the pump capacity and head are sufficient to supply the site and meet the minimum requirement by NFPA or not.

The calculation is three stage:

o To check the given capacity and head of the pump with the remotest area of the Operation Area.

o To check the given capacity and head of the pump with the remotest landing valve.

Sequence of hydraulic calculations:

o Sprinkler and fire hose cabinet:

Inside Hose stream allow will be 100 gpm (as per item Table 11.2.3.1.2 Hose Stream Allowance and Water Supply Duration Requirements for Hydraulically Calculated Systems page 13-123, NFPA 13, 2013 Edition).

Determine the remotest operation area which located in the Roof floor (mechanical room) of work shop building.

Determine the hazard of the operation area (Ordinary Hazard as per item A.5.5 page 13-266 NFPA 13-2013 Edition).

Default K Factor of sprinkler will be 5.65 gpm/psi^ (Selected for Light Hazard).

Minimum Desired Density will be 0.1 gpm/ft (as per item 11.2.3 page 13-122 NFPA 13-2013 Edition).

Sprinkler system type will be wet system.

Max area per sprinkler will be 130 ft (as per Table 8.6.2.2.1(a) Protection Areas and Maximum Spacing of Standard Pendent and Upright Spray Sprinklers for Ordinary Hazard page 13-35 NFPA13, 2013Edition).

9 of 50






The number of calculated sprinklers will be 11 sprinklers (as per FIGURE A.23.4.4 Example of Determining the Number of Sprinklers to be calculated. page 13-395 NFPA 13, 2013 Edition) )(this number of sprinkler may be increase according to architectural drawing to cover selected area from Density/area curve)

Design area will be 1500 ft (as per item 11.2.3 page 13-122 NFPA 13-2013 Edition, Find attached file).

Area per sprinkler will be 13.77949 ft * 942.8.9 ft = 136 ft. Total Sprinkler to Calculate = 1500 / 136 = 11 sprinklers. Number of sprinklers on branch line = (1.2 1500)/14 = 3

sprinklers. o Landing Valve Calculation:

Class of hose is I (as per item 7.3.2 Class I Systems page 14-18 NFPA 14, 2013 Edition).

Residual Pressure for Class I will be 100 psi (6.9 par) (as per item 7.8.1 Minimum Design Pressure for Hydraulically Designed Systems page 14-19 NFPA 14, 2013 Edition).

Flow will be 250 gpm (as per item 7.10.1.2 Hydraulic Calculation Requirements page 14-20 NFPA 14, 2013 Edition).

Calculated K-Factor Will be as per formula (K=Q/P) where Q is Flow of the landing valve (250 gpm) and P is the Pressure (100 PSI) So the K=250100 = 25 (as per item 23.4.2.5 K-Factor Formula page 13-236 NFPA13, 2013 Edition).

Type Of hydraulic calculation methods:

o Demand Mode (I need to put the minimum residual pressure at remotest area, if Sprinkler will be 15 PSI as per Table 11.2.2.1 Water Supply Requirements for Pipe Schedule Sprinkler Systems page 13-122 NFPA13, 2013 Edition) and minimum density as per item 11.2.3 page 13-122 NFPA 13-2013 Edition).

o Supply Mode (if we have given Flow and Pressure)

A.4.4 Biocides and other chemicals that are approved andused for the prevention and mitigation of MIC and that do notadversely affect the fire-fighting properties of the water or theperformance of the fire sprinkler system components are notprohibited.

A.4.6 Non-system components can adversely affect the opera-tion and longevity of the fire sprinkler system.Objects connectedto the sprinkler system can displace sprinkler systempiping, caus-ing obstruction to the spray pattern of sprinklers, delay the acti-vation of a sprinkler, or cause chemical compatibility problemsthat can cause the failure of sprinkler system components.

A.5.1 Occupancy examples in the listings as shown in thevarious hazard classifications are intended to represent thenorm for those occupancy types. Unusual or abnormal fuelloadings or combustible characteristics and susceptibility forchanges in these characteristics, for a particular occupancy,are considerations that should be weighed in the selection andclassification.

The light hazard classification is intended to encompassresidential occupancies; however, this is not intended to pre-clude the use of listed residential sprinklers in residential oc-cupancies or residential portions of other occupancies.

A.5.2 Light hazard occupancies include occupancies havinguses and conditions similar to the following:

(1) Animal shelters(2) Churches(3) Clubs(4) Eaves and overhangs, if of combustible construction with

no combustibles beneath(5) Educational(6) Hospitals, including animal hospitals and veterinary fa-

cilities(7) Institutional(8) Kennels(9) Libraries, except large stack rooms

(10) Museums(11) Nursing or convalescent homes(12) Offices, including data processing(13) Residential(14) Restaurant seating areas(15) Theaters and auditoriums, excluding stages and prosce-

niums(16) Unused attics

Note that it is not the committees intent to automaticallyequate library bookshelves with ordinary hazard occupancies orwith library stacks. Typical library bookshelves of approximately8 ft (2.4 m) in height, containing books stored vertically on end,held in place in close association with each other, with aisleswider than 30 in. (762 mm) can be considered to be light hazardoccupancies. Similarly, library stack areas, which aremore akin toshelf storage or record storage, as defined in NFPA 232, shouldbe considered to be ordinary hazard occupancies.

A.5.3 For purposes of these definitions, Class I, Class II, ClassIII, and Class IV commodities would be considered to havemoderate rates of heat release, while Group A plastics wouldbe considered to have high rates of heat release. Stockpiles areconsidered to include display merchandise (mercantile) andarrangements of combustibles ancillary to operations withinthe occupancy as opposed to dedicated storage areas wherethe fire loading is generally more severe.A.5.3.1 Ordinary hazard (Group 1) occupancies include oc-cupancies having uses and conditions similar to the following:(1) Automobile parking and showrooms(2) Bakeries(3) Beverage manufacturing(4) Canneries(5) Dairy products manufacturing and processing(6) Electronic plants(7) Glass and glass products manufacturing(8) Laundries(9) Restaurant service areasA.5.3.2 Ordinary hazard (Group 2) occupancies include oc-cupancies having uses and conditions similar to the following:(1) Agricultural facilities(2) Barns and stables(3) Cereal mills(4) Chemical plants ordinary(5) Confectionery products(6) Distilleries(7) Dry cleaners(8) Exterior loading docks (Note that exterior loading docks

only used for loading and unloading of ordinary combus-tibles should be classified as OH2. For the handling offlammable and combustible liquids, hazardous materi-als, or where utilized for storage, exterior loading docksand all interior loading docks should be protected basedupon the actual occupancy and the materials handledon the dock, as if the materials were actually stored inthat configuration.)

(9) Feed mills(10) Horse stables(11) Leather goods manufacturing(12) Libraries large stack room areas(13) Machine shops(14) Metal working(15) Mercantile(16) Paper and pulp mills(17) Paper process plants(18) Piers and wharves(19) Plastics fabrication, including blow molding, extruding,

A.5.4.2 Extra hazard (Group 2) occupancies include occu-pancies having uses and conditions similar to the following:

(1) Asphalt saturating(2) Flammable liquids spraying(3) Flow coating(4) Manufactured home or modular building assemblies

(where finished enclosure is present and has combus-tible interiors)

(5) Open oil quenching(6) Plastics manufacturing(7) Solvent cleaning(8) Varnish and paint dipping

A.5.5 Other NFPA standards contain design criteria for firecontrol or fire suppression (see Section 5.5 and Chapter 2). Whilethese can form the basis of design criteria, this standard de-scribes the methods of design, installation, fabrication, calcu-lation, and evaluation of water supplies that should be used forthe specific design of the system.

Other NFPA standards contain sprinkler system design cri-teria for fire control or suppression of specific hazards. Thisinformation has been either referenced or copied into Chap-ter 22 using NFPAs extract policy.

A.5.6 Specification of the type, amount, and arrangement ofcombustibles for any commodity classification is essentially anattempt to define the potential fire severity, based on its burningcharacteristics, so the fire can be successfully controlled by theprescribed sprinkler protection for the commodity class. In ac-tual storage situations, however, many storage arrays do not fitprecisely into one of the fundamental classifications; therefore,the user needs to make judgments after comparing each classifi-cation to the existing storage conditions. Storage arrays consist ofthousands of products, whichmake it impossible to specify all theacceptable variations for any class. As an alternative, a variety ofcommon products are classified in this annex based on judg-ment, loss experience, and fire test results.

Table A.5.6 provides examples of commodities not ad-dressed by the classifications in Section 5.6.

Table A.5.6.3 is an alphabetized list of commodities withcorresponding classifications.

Table A.5.6.3.1 through Table A.5.6.3.4 and Table A.5.6.4.1provide examples of commodities within a specific class.

A.5.6.1.1 Commodity classification is governed by the typesand amounts of materials (e.g., metal, paper, wood, plastics)that are a part of a product and its primary packaging. How-ever, in a storage or warehousing situation, classification is alsoaffected by such factors as the primary storage or shippingcontainer material, the amount of air space, and the location
