Questions regarding these contents should be directed to the Fire Inspections Branch at 703-246-4849 during regular office hours, Monday thru Friday, 8 a.m. to 4 p.m.

OVERVIEW

The Fire Prevention Code defines "high-piled storage area" as the area within a building which is designated, intended, proposed, or actually used for high-piled combustible storage. High-piled combustible is the storage of combustible materials in closely packed piles or combustible materials on pallets, in racks, or on shelves where the top of the storage is greater than 12 feet in height. When required by the fire code official, high-piled combustible storage also includes certain high-hazard commodities, such as Group A plastics, rubber tires, flammable liquids, idle pallets, and similar commodities where the top of the storage is greater than 6 feet in height.

Required fire protection features for high-piled combustible storage are generally determined by the storage commodity type (i.e., combination of products, packing materials, and containers) as well as the height, quantity, and method of commodity storage. A key concept in the protection of buildings containing high-piled combustible storage is ensuring the level of fire protection provided is adequate for the commodity types and storage arrangements actually in place.

 

PERMIT REQUIRED

An operational permit (i.e., Fire Prevention Code Permit) is required to use a building or a portion thereof as a high-piled storage area exceeding 500 square feet. The primary focus of this permit requirement is to ensure the required level of protection and planning (e.g., fire protection systems, portable fire extinguishers, smoke and heat vents, fire department access, evacuation plan, etc.) is adequate, code compliant, and properly maintained for a particular high-piled storage area. A Fire Prevention Code Permit (FPCP) for high-piled combustible storage will only be issued after documentation requirements have been satisfied.

HIGH-PILED STORAGE PLAN REQUIRED. In order to satisfy the requirements for a high-piled combustible storage operational permit (i.e., FPCP), a high-piled combustible storage plan must be reviewed and approved by the Fire Marshal before the operational permit will be issued.

FIVE STEP PROCESS. The following steps form the procedural framework for completing the public safety plan and site layout submittal/retrieval and for scheduling a fire marshal site inspection.

STEP 1 - PREPARE REQUIRED DOCUMENTATION

The following documentation requirements must be satisfied before a Fire Prevention Code Permit (FPCP) for high-piled combustible storage will be issued. Prior to making application for an FPCP, the high-piled combustible storage plan review application, plan review documents, and completed evacuation plan (for public accessible storage areas) must be submitted, reviewed, and approved by the Fire Marshal in PLUS. Following approval, a copy of the approved high-piled combustible storage plan and plan review application shall be maintained on the premises in an approved location, readily available for inspection by the Fire Marshal.

Plan Review Documents. In accordance with Section 3201.3 of the Fire Prevention Code, at the time of building permit application for new structures designed to accommodate high-piled storage or when requesting a change of occupancy/use (storage hazard change), and at the time of application for a high-piled combustible storage permit, plans and specifications shall be submitted for review and approval. All plans, specifications, documents, or designs for high-piled combustible storage shall bear the name and address of the author and his/her occupation.

To avoid confusion with other construction documents associated with the building, approved documentation for high-piled combustible storage is known as the High-Piled Storage Plan.

Floor Plan Specifications. Designers shall provide a scaled floor plan of the building showing locations and dimensions of all high-piled combustible storage areas and storage arrangements. Dimensional drawings are not acceptable. Scaled drawings shall be: 1/8 inch = 1 foot

Plan Review Application. A high-piled combustible storage plan review application must be submitted with the high-piled combustible storage plan review documents in PLUS

Fire Evacuation Plan. In accordance with Section 3201.4 of the Fire Prevention Code, an evacuation plan for public accessible areas and a separate set of plans indicating location and width of aisles, location of exits, exit access doors, exit signs, height of storage, and locations of hazardous materials shall be submitted at the time of permit application for review and approval. Following approval of the plans, a copy of the approved plans shall be maintained on the premises in an approved location. Mercantile shall comply with Mercantile Evacuation Planning.

 

PLAN REVIEW APPLICATION INSTRUCTIONS

The following information must be accurately provided on the plan review application:

  1. STORAGE AREA IDENTIFICATION
    • Are there multiple storage areas separated by a 1-hour fire protection rating?
    • This question is based on defining the high-piled storage area. Section 3206.3.2 allows a storage area separated by a 1-hour fire barrier be considered a separate high-piled storage area for determining the requirements in Table 3206.2. If you answer YES, clearly show the 1-hour (or greater) fire barrier wall on the plans and fill out a separate application (items 1-7 only) for each area that meets this definition.
    • Description/Name of high-piled storage area.
    • This is the name of the high-piled storage area. Where item A is YES, this will help separate the multiple high-piled storage areas. These areas should be named on the plans.
    • Aggregate Area:
    • This is the total square footage of the high-piled storage area. When calculating high-piled storage area for shelf and solid-pile storage, the actual area used for storage (not including aisles) should be determined. When calculating high-piled storage area for rack storage, the aisle width required in NFPA 13 shall be included in the total area.
    • Ceiling Height:
    • Provide the minimum and maximum ceiling height in the high-piled storage area.
    • High-Piled Storage Area Accessible to the Public?
    • This is used to determine the options allowed in Table 3206.2. If YES, a separate evacuation plan required by SFPC 3201.4 shall be prepared and submitted with this plan.
  2. COMMODITY CLASSIFICATION
    • Description of combustible materials stored: Provide a brief description of the commodities that are stored. If more space is needed, provided additional sheets.
    • Commodity classification(s) per SFPC 3203: SFPC 3203 defines each class of commodity. Provide the class of commodity that is to be stored.
    • Use of flame-retarding modifiers to change the commodity classification? SFPC 3203.1 states that the use of flame-retarding modifiers could change the commodity classification. Are you claiming to use this allowance to change the commodity classification?
    • Does the physical form of the material change the commodity classification? SFPC 3203.1 states that the change in physical form could change the commodity classification. Are you claiming to use this allowance to change the commodity classification?
    • If yes to C or D, provide documentation validating related changes in commodity classification. Provide documentation that supports the change in commodity classification. Documentation may include specifications, testing data, or other supporting documents.
    • Specify commodity class limitations in accordance with SFPC 3204. Please review SFPC 3204. The high-piled storage area is to comply with the highest commodity classification being claimed with exception. When SFPC 3204.2 applies, clearly show on the plans the locations of the higher commodity being used.
    • Amount of Group A plastics are classified as high-hazard commodity. This is a declaration that Group A plastics, if applicable, have been determined not to constitute a commodity classification of High-Hazard. (SFPC 3203.7.4)
  3. HAZARDOUS MATERIALS
    • Identify if the following hazardous materials are part of the proposed high-piled storage plan. Refer to the SFPC chapter indicated for material-specific storage limitations and/or requirements. When these hazards exist in the high-piled storage areas, other chapters also apply to the storage of these materials.

The preferred method used for storage along walls shall be a line placed at the maximum storage height. The preferred method used for open area and aisles shall be a sign with the maximum storage height posted and the bottom of the sign installed at the maximum storage height. Additional methods used shall be approved by the Fire Marshal. Specifications for all maximum storage height signage shall be clearly illustrated in the plan.

STEP 2 - SUBMIT REQUIRED DOCUMENTATION

An application for high-piled storage plan review shall be made via a Storage - High-Piled/Other record in PLUS.

Plan Review Fees. An hourly fee of $156 will be charged for the review of the high-piled combustible storage plan review documentation. Hourly fees are charged in quarter hour increments ($39), rounded to the next quarter hour. 

 

STEP 3 - Retrieve Approved Documentation

After the submitted documentation is reviewed and approved, review fees are invoiced and shall be paid for release of stamped plans.

Notice about Fire Marshal Approval. In accordance with Section 107.7 of the Fire Prevention Code, plans approved by the fire official are approved with the intent that they comply in all respects to the Fire Prevention Code. Any omissions or errors on the plan review submittals (i.e., plan review application, high-piled storage plan, and evacuation plan) do not relieve the permit applicant of complying with all applicable requirements. Generally, application for a Fire Prevention Code Permit (FPCP) may be made when approved plans are retrieved.

STEP 4 - Permit (FPCP)

In accordance with Section 3201.2 of the Fire Prevention Code (as amended by Fairfax County), a Fire Prevention Code Permit (FPCP) is required to use a building or a portion thereof as a high-piled storage area exceeding 500 square feet. The FPCP record will be created on your behalf by staff.  The permit fee will be invoiced upon processing.

Permit Notice. In accordance with Section 108.3.6 of the Fire Prevention Code, the issuance or granting of an operational permit shall not be construed to be a permit for, or an approval of, any violation of any of the provisions of this code or of any other ordinance of the jurisdiction. Permits presuming to give authority to violate or cancel the provisions of this code or other ordinances of the jurisdiction shall not be valid. The issuance of a permit based on other data shall not prevent the fire official from requiring the correction of errors in the provided documents and other data. Any addition to or alteration of approved documents shall be approved in advance by the fire official, as evidenced by the issuance of a new or amended permit.

STEP 5 - Schedule a Fire Marshal Site Inspection

In accordance with Section 108.2.2 of the Fire Prevention Code, before a new operational permit (i.e., Fire Prevention Code Permit) is approved, the fire official is authorized to inspect the receptacles, vehicles, buildings, devices, premises, storage spaces, or areas to be used to determine compliance with this code or any operational constraints required. A copy of the approved high-piled combustible storage plan and plan review application shall be maintained on the premises in an approved location, readily available for inspection by the Fire Marshal. Site inspections may be scheduled by calling 703-246-4849.
