IFS has over the years been asked by thousands of people in all 50 states for an easily accessible and easy to use guide that helps explain their Code Compliance issues concerning FR Decorations, Interior Finishes, and Thermal Barrier Applications.
With the combined efforts of many in-house and outside resources, this resource is intended for use by personnel and administrators of areas of public assembly and occupancy classifications to maintain and improve life safety conditions for the benefit of residents and employees. This document is intended to provide information to facilities, but it is not necessarily fully inclusive of all details of LSC 2000 or other NFPA Standards. Determinations of compliance with Life Safety Code regulations are made at the time of survey.
Federal, State and Municipal Building Codes all have maintenance clauses pertaining to the flame retardancy of decorative materials and interior finishes when used in areas of assembly or egress. Many have established on-going maintenance cycles, protocol and recertification programs for fire-retardant materials whose cycles vary in length of time. Any flame retardant or resistant item that has had its fire resistant coating removed or has had a flammable coating (including, but not limited to airborne dust and flammable paints) applied or adhered to its surface, will have negated its flammability rating and must be, at that point, MAINTAINED to certify its original flame retardant condition.
New construction and retrofits of existing facilities are also required to meet the current codes established. Certificates of Flameproofing Conformance are provided for items that meet applicable Code Standards. When Certificates of Flameproofing Conformance expire, the liabilities of the flame retardancy of those treated items are no longer the responsibility of the company originally issuing the certificate.
ICC Chapter 8 Interior Finishes, Decorative Materials and Furnishings -
NFPA 703 and Life Safety Code 101 for Interior Finishes clearly states that "Interior Finishes in areas of Public Assembly shall meet the required Fire Codes for that Occupancy and that the Fire Retardant properties on treated items be Maintained or Renewed as per Manufacturer's Instructions and under the service conditions of actual use, using only approved flame retardant coatings."
In 2010 the Center for Medicaid (CMS) issued a Corrective Memorandum entitled "Interior Finish Documentation Requirements for Multiple Providers."
- Clarifies Policy on Interior Finish -- this memorandum clarifies policy regarding existing interior finish for fire safety purposes.
- No Requirement to Document Flame Spread Rating -- existing interior finish materials.
- Documentation of Flame Spread Rating Required -- only for newly installed interior finish materials.
The memo states that… “Generally these finishes are renewed on a regular basis when the facility updates and refreshes its interior and can obtain the needed documentation at that time.” You can read the full text
Fire-retardant coatings. The required flame spread or smoke-developed classification of surfaces shall be permitted to be achieved by application of approved fire-retardant coatings, paints or solutions to surfaces having a flame spread rating exceeding that permitted. Such applications shall comply with NFPA 703 and the required fire-retardant properties shall be maintained or renewed in accordance with the manufacturer's instructions.
Wall and ceiling finish requirements. Interior wall and ceiling finish shall have a flame spread index not greater than that specified in Table 806.3 for the group and location designated. Interior wall and ceiling finish materials, other than textiles, tested in accordance with NFPA 286 and meeting the acceptable criteria of Section 806.2.1.1, shall be permitted to be used where a Class A classification in accordance with ASTM E84 is required.

Decorative Materials IFC Chapter 8, NFPA Life Safety Code Chapter 8 -
Curtains, draperies, hangings and other decorative materials suspended from walls or ceilings shall be certified meet the flame spread criteria of NFPA 701 or shall be non-combustible.
Inherently Fire Retarded Fabrics
Buyers and Fire Inspectors should be aware of two (2) categories of Inherently Flame Retardant textiles. Those whose flammability performance is based upon Additives (FRT) at the processing stages and those textiles which are Inherently Fire Resistant such as Kevlar, Nomex and Asbestos. Both are often marketed as Inherently Flame Retardant (IFR).
Unless Inherently Flame Retardant Fabrics are Truly Kevlar, Nomex or Asbestos in origin, fabrics labeled Inherently Flame Retardant could lose their Fire Resistance due to aging, humidity, laundering or airborne dust. Many older (FRT) IFR’s will not pass simple flammability field tests that are indicative of Flame Resistance.
Ref: www.dupont.com (regarding Inherently Flame Resistant Fabrics)
“These materials are made flame-resistant by the application of flame-retardant chemicals. A chemical additive in the fiber or treatment on the fabric is used to provide some level of flame retardancy”,
“FR-treated garments may be damaged by chlorine bleach with hard water, or exposure to oxidizing chemicals in the workplace”, “exposure to oxidizing could, over time, compromise the flame-resistant properties of garments made with FR-treated fabrics.”
Ref: www.iweiss.com (regarding Inherently Flame Resistant Fabric)
“IFR Fabrics are manufactured from polyester yarns to meet NFPA 701 testing protocol without any additional treatment. These fabrics are expected to retain their IFR properties for the life of the material, however, THIS CANNOT BE GUARANTEED. Conditions of use including time, humidity, excessive dust or dirt etc. may adversely affect the flame retardant capabilities. A yearly field test to verify the status is strongly recommended.”
“These fabrics are expected to retain their IFR properties for the life of the material. However, it should be understood that IFR does not mean permanently flame proofed. Ambient conditions, cleaning practices, excessive dust build up, etc., can affect the fabric's flammability characteristics. This is true of synthetic IFR fabric or any other cellulose constructed and chemically treated fabric. Proper care, cleaning, and periodic testing can maintain the proper characteristics.”
Ref: www.dazian.com regarding Inherently Flame Resistant Fabrics)
“A Flame Retardant additive is added to the fiber to give the fabric Permanent Flame Resistance. A topical finish is often added in fabric dyeing and finishing insuring in fabric formation the FR properties are maintained. Although there may be no degradation from washing or dry cleaning, the same factors of environment, use of added components and further processing may compromise its flame resistance. Retesting every few years and re-flameproofing may still be required.”

Furnishings IFC Chapter 8, NFPA Life Safety Code Chapter 8 -
Upholstered furniture and mattresses must meet the flammability criteria as established by ASTM E 1537 or California Technical Bulletin 133 (Mattresses are required to meet California Technical Bulletin 129) The Cal Tech 133 is the prescribed test method for furniture flammability requirement in areas of public occupancy.
California Technical Bulletin 117 is a mandatory standard for residential upholstered furniture. The furniture fabric covering is not tested for flammability. However, there are thousands of public occupancies that contain upholstered furnishings that only meet the Cal Tech 117 test requirements.
To correct this oversight can be used to flame retard the fabric.
IN I-1, I-2 and R-4 OCCUPANCIES
The ICC Building Code Chapter 5 General Building Heights and Areas is the driver of assembly ratings for areas of incidental use and accessory areas in conjunction with Chapter 3. From requirements can be linked to for the specified type of occupancy.
As an example, if an R-4 has a change in the ambulatory occupancy and becomes classified as an I-2 the fire codes can change dramatically overnight ( ). If there is an accessible basement that is used for storage this area becomes classified as an Incidental Use area or an accessory area depending on the square feet of the area and is now a separate fire area of the structure.
This area for storage is now classified as an S-1 (Moderate Hazard) or S-2 (Low Hazard) depending on the materials stored ( ). The entire structure is now a mixed use non-separated occupancy. Chapter 5 Section 508.3.1 assists in determining if this is an Incidental or Accessory area. Chapter 3 breaks down the classification process of an S-1 and S-2.
Chapter 5 section 508 Tables 508.2 and 508.3.3 can be used to determine the floor, floor/ceiling assembly hourly requirements required for this type of mixed use occupancy. The use of these tables will help to determine if a sprinkler system or hourly rated assembly is required or if both are required.
There are additional sections of the Code that deal with the type of construction, size of the area below grade, number of exits to the exterior of the structure and distances to these exits that are referenced from Chapter 5 that are also used to complete the determination of the type of assembly needed. Chapter 5 is a good index starting point to determine your needs for Code Compliance in all occupancies.

Code Compliance History - the NFPA and the formation of the ICC
Since the early 1900s, US Fire Code Regulations were regionalized within the US through ICBO, BOCA and SBCCI. In 1994 these regional sections merged to form the to create a coordinated uniformity in national building codes.
In 1997 the first edition of the International Building Code (IBC) was published by the ICC. Most States have adopted the ICC Codes or parts thereof that address Fire Code, Residential Code, Existing Building Code, and other areas. Many states and municipalities also use the NFPA 101 Life Safety Code for Fire Code Requirements. These codes establish minimum requirements based on occupancy classification.
originally worked in conjunction with ICC to establish standard requirements for the IBC and other ICC Codes including the International Fire Code. Repeated failures and disputes between the two organizations over the minimum requirements to be adopted led the NFPA to withdraw from any further collective efforts of writing the IFC or other codes published by the ICC.
The IFC and NFPA 101 Life Safety Code can often times be difficult to combine as occupancy classifications and requirements can differ between the two organizations and can lead to interpretation conflicts when combining the two together.
