9-1-00 Design Requirements
The following design requirements apply to all fire protection systems. The engineering goals and objectives are to provide uniformity of design; combine the best overall economy with suitability of design; and be compatible with all other building systems. Provision shall be made for the addition of future expansion as determined by the NIH on a project-by-project basis.
Fire protection design shall follow the National Fire Protection Association (NFPA) National Fire Codes (NFC), International Fire Code (IFC), and the International Building Code (IBC), unless specifically altered or amended in this document. NFPA-5000 Building Construction and Safety Code is not utilized. When a conflict between the various code requirements exists, the most stringent/conservative standard shall apply. All portions of the NFPA NFC shall be followed including appendices, recommended practices, interim amendments, and formal interpretations. The A/E shall interpret only NFPA NFC use of the “should” as “shall” (i.e., must be followed) at all times. Any departure from NFPA NFC or IBC requirements must be clearly delineated in the A/E’s “Fire Protection Engineering Analysis,” if required (see requirement noted below), or other project correspondence, along with justification of the departure.
A. Authority Having Jurisdiction:
The NIH Division of the Fire Marshal (DFM) is the AHJ defined in the NFPA and IFC requirements
9-1-10 Design Guidance
A. Type of Construction:
The construction type selected shall, at minimum, meet the lowest classification required by the IBC for the proposed occupancy, based on occupancy, building height, building area, and other factors, as identified in the IBC. NIH fire hazard classification for laboratory areas is considered Class “B” per NFPA 45 definitions.
B. Occupancy Classification:
Occupancy classification shall be per NFPA101 LSC. Laboratories and adjunct areas are classified as “Industrial”; animal holding facilities are classified as “Storage.”
C. Fire-Resistant Materials and Construction:
All laboratory corridor walls shall have a minimum one hour fire rating. All one hour fire-rated partitions shall have 45 minute opening protection. Each vision panel shall not exceed 0.84sq m (9 sq ft). Open storage in the laboratories is not permitted, on a horizontal plane, within 0.46 m (18 in.) of the sprinkler deflectors (as measured vertically from the bottom of the sprinkler deflector to the horizontal plane). Enclosed perimeter storage (i.e., within cabinets) to the underside of the ceiling is permitted. In areas that also have a pressure differential at the ceiling, which can affect the operation characteristics of the concealed heads, the gasketed concealed heads shall be specifically listed for use in ceilings with pressure differentials.
D. Flammable Storage Cabinets:
A flammable storage cabinet (FSC) constructed of metal shall be provided in each laboratory. Additional FSC’s shall be provided per NFPA 45 requirements. The exterior of all FSC’s shall be appropriately signed. The FSC shall be located as remotely as possible from the exit doors of the laboratory and shall not be installed beneath fume hoods. FSC’s shall not be located in corridors. The integrity of the FSC shall not be compromised by its mounting method. The FSC shall not be vented.
9-1-20 Design Information
The A/E shall use and comply with the design and safety guidelines, and references listed below, and other safety guidelines received from the NIH Project Officer or as required by the program. The A/E shall utilize the latest editions of reference design and safety guidelines available at the time of the design contract award.
• National Fire Codes, all volumes, National Fire Protection Association (NFPA), 1 Batterymarch Park, Quincy, MA 02269-9101, with the exception of NFPA-5000 Building Construction and Safety Code.
• The International Building Code (IBC)
• The International Building Code and the International Plumbing Code: International Code Council, Inc., and Building Officials and Code Administrators (BOCA) International, Inc.: 4051 West Flossmoor Road, Country Club Hills, IL 60477-5795.
9-1-30 Design Document Requirements
A. Listed Equipment and Valves:
All fire protection devices, equipment, and materials shall be listed for the intended use. “Listed” is defined as equipment and materials that are identified in the Factory Mutual Research (FM) Approval Guide and/or the various directories of Underwriters Laboratories (UL). Testing by another nationally recognized laboratory may be approved by DFM on a case-by-case basis.
B. Fire Protection Submission Guidelines:
The A/E shall provide language in the contract documents to reference the use of the “Fire Protection Submission Guidelines” for all fire protection system(s) in government owned facilities. This manual contains the requirements for design and construction submissions as well as construction submittals and inspections.
C. Fire Hydrants
Construction contract drawings shall show the locations of all hydrants that are intended to protect a new or renovated facility.
• Hydrant and standard thrust block details shall be provided.
D. Fire Alarms
Documents shall include system reprogramming, modification of graphic interfaces, and up-dating of system as-built drawings.
E. Self Luminous Signs
Project specifications shall include a reporting requirement to immediately contact DRS (301) 496-5774 or 911, from an in-house campus phone, to report damaged or broken signs and to receive removal instructions and procedures.
