Dear Applicant:

Please be advised that we have made a general review of the drawings, calculations, and equipment data for the proposed Fire Suppression System, based on the submittal package received for the above referenced project.  This review is governed by the Official Manual of the Office of State Fire Marshal, which contains the adopted laws, codes, rules, and regulations of this office.  This review, in no way, shall permit and/or authorize any omissions or deviations from the specific requirements of the Official Manual.  Requirements cited in this review do not relieve the licensed fire suppression system designer and the Professional Of Record, when required by LA RS 37, from complying with all the requirements contained in the Official Manual.  Subsequent to our general review of the submittal package, we have determined that the drawings, calculations, and equipment data appear to satisfactorily comply with the adopted laws, codes, rules and regulations of the State Fire Marshal, subject to the following requirements and review qualifications:

NOTE:  THE COMMENTS LISTED BELOW IDENTIFY APPARENT DEFICIENCIES DETECTED IN OUR REVIEW OF THE DOCUMENTS SUBMITTED.

1.	20: 1-4  Complete plans shall provide detailed information regarding the pump, driver, controller, power supply, fittings, suction and discharge connections and water supply conditions.  This item is deficient in that the drawings do not indicate provision of the following:

	a)  20: 2-5.1  Provide a pressure gauge, connected near the discharge casting, in accordance with this section.

	b)  20: 2-6.1  Each pump(s) shall have an automatic relief valve listed for the fire pump service, installed on the discharge side of the pump before the discharge check valve, and arranged for discharge to a drain.  Minimum size of the automatic relief valve shall be 3/4 in. for pumps with a rated capacity not exceeding 2500 gpm.  
	
2.	13: 4.1 and 8.1.1    A building, where protected by an automatic sprinkler system installation, shall be provided with sprinklers in all areas except where specific sections of this standard permit the omission of sprinklers. This item is deficient in that the pump enclosure, which is in a sprinklered building, is not provided with a sprinkler. 

______________________________________________________________________________________

NOTE:  THE FOLLOWING COMMENTS IDENTIFY ISSUES FOR INFORMATIONAL AND CAUTIONARY PURPOSES OR ISSUES THAT COULD NOT BE VERIFIED IN THE SUBMITTED DOCUMENTS.

3.	This fire protection system review is limited to the original plan review scope as per State Fire Marshal letter P0285396. 

4.	This review applies to the riser(s), piping lay-out and sprinkler head locations, for compliance with NFPA 13, 2002 edition, as shown on the drawings for the above referenced project.  NFPA 25, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems is a requirement of this office and shall be adhered to. 

5.	This review applies to the fire pump, for compliance with NFPA 20 Fire Pumps, 1999 edition, as shown on the drawings for the above referenced project.  NFPA 25, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems is a requirement of this office and shall be adhered to. 

6.	This review is based on a project supplied by:

	a)  A city water supply of 55 psi static and 28 psi residual, flowing 805 gpm; test indicated as performed by Insul-Tech, on February 11, 2005, at 8:00 AM.

	b)  A new fire pump rated at 100 psi at 500 gpm; having a "net" contribution of approximately 110 psi at churn and 87 psi, flowing 750 gpm.

	c)  An estimated pump total discharge of 109 psi at churn and 136 psi residual, flowing 572 gpm. 
	
7.	The system, at the West end of the building, was calculated as an ordinary hazard (Group 2) occupancy class.  The calculations indicate the following system demand, as submitted:

	a)  572 gpm at 38 psi at the pump outlet (base of riser),  572 gpm at - 58.3 psi  at the pump inlet , and 822 gpm at - 49.7 psi at the source, adjusted to 25 psi, to allow minimum 16 psi suction pressure at the pump inlet, and indicating 102 psi "margin".

	b)  The system demand was based on a density of 0.35 gpm/sq.ft. over a 1560 sq.ft. design area.

	c)  The system demand includes the discharge of, "K"=8.0, standard spray sprinklers having protection areas of 100 sq. ft. each and allows 250 gpm outside hose flow at the city connection.

	d)  The calculations include 3.0 psi residual pressure loss, based on installation of the following backflow preventer: Manufacturer: Ames, Type: Double Check, Model Number: 2000SS, Size:  8 inch, located in the private main. 
	
8.	13: 14.4.4.5 The calculations for the system grid are based on the following pipe:  6 inch riser and feed main,  6 inch near main,  4 inch far main and 2 1/2 inch grid lines, all of Schedule Ten pipe.

9.	13: 5.3.2 and 12.1  Due to the ordinary hazard (Group 2) basis of design, this review does not apply to:

	a)  Storage of any commodity to more than 12 ft. high.

	b)  Storage of Class IV commodities on racks to more than 10 ft. high. (See 5.6.3.4 and Table A-5.6.3.4 for examples.)

	c)  Storage of Group A plastics exceeding the limits defined as Miscellaneous Storage in 3.3.15 or to more than 5 ft. high. (See 5.6.4.1 and Table A-5.6.4.1 for examples.)

	d)  Storage of rubber tires exceeding the limits defined as Miscellaneous Tire Storage in 3.11.4 or, in any arrangement, to more than 5 ft. high or to more than 2000 sq. ft. total area.

	e)  Storage or display of flammable and combustible liquids beyond limitations described in NFPA 30, Chapter 4.

	f)  Storage or display of Level II or Level III aerosols beyond limitations described in NFPA 30B, Chapter 5.

	g)  Storage of wooden pallets exceeding more than 6 ft. in height or plastic pallets exceeding more than 4 ft. in height; in fixed single row racks.

	h)  Extra Hazard uses, such as:  Combustible hydraulic fluid use areas, Die casting, Metal extruding, using flammable liquids having flash points below 100°F, Rubber reclaiming, compounding, drying, milling, vulcanizing, Flammable liquids spraying, Flow coating, Open oil quenching, Plastics processing, Solvent cleaning, or Varnish and paint dipping. (See 13: 5.4)

	i)  Special Occupancy Hazards, not specifically indicated on the reviewed drawings. (See 13: 5.5 and Chapter 13)
