3. Review of Agenda. Chair Hirschler reviewed the agenda and indicated the primary purpose of this meeting was to act on all proposals for NFPA 557.

4. Approval of Minutes. The minutes of the October 6, 2009 meeting were approved

with no modifications. 5. Review of Revision Cycle Information. Ms. Collette gave the Technical Committee

Meeting Introduction presentation and reviewed the Fall 2011 revision cycle information for NFPA 557 (See Page 4).

6. Preparation of NFPA 557 ROP. All public proposals included in the agenda

package were addressed and committee proposals were generated. See NFPA 557 letter ballots and the Fall 2011 Report on Proposals (ROP) for committee actions on these proposals. As this is the first edition of the document, the committee fully reviewed the current draft of NFPA 557 and made additional editorial and technical changes that will be reflected in the ROP draft.

7. Other Business. The committee formed a task group consisting of M. Hirschler, C.

Beyler, D. Bueche, and E. Buc to review the ROP draft of NFPA 557 and identify issues to be addressed by or at the ROC meeting. Ms. Collette will serve as a liaison to this task group.

Ms. Collette also reviewed briefly the revision cycle for NFPA 555 which has entered into the Annual 2012 revision cycle (See Page 5). Due to the revision history of this document, the committee agreed that a meeting via conference call would be most appropriate. The ROP meeting for NFPA 555 has been scheduled for Wednesday, January 19, 2011 from 1:00 to 4:00 EST.

Report on Comments – November 2011 NFPA 557_______________________________________________________________________________________________557- Log #39

_______________________________________________________________________________________________David Fuller, Millville, MA

557-4Reconsider Proposal 557-4 Log #2 and return entire document to committee.

This draft standard is not complete and, in its present form, has numerous flaws. A small error in theproposed methodology can have an enormous impact on building fire performance (putting lives and property at risk).There has been no testing carried out in support the proposed methodology and the theoretical support cited is verylimited. The proposed methodology does not take into consideration many of the major variables that define firescenarios in buildings. The proposed methodology for determining the fire load needs to be extensively evaluatedthrough additional peer reviews and several rounds of public commenting before this standard should be released.The concept of using fire frequency and structural collapse probability functions to achieve an undefined Risk Objective

(Section 6.2.3) is fundamentally flawed. The use of fire frequency (Section 6.2.3) has no relevance in a fire loadcalculation. In order to design the desired building fire performance, the presence of a fire has to be assumed. If no fireis present, no fire protection would be needed.Designing to the statistically relevant fire frequency and combustible loading by definition means you are knowingly

putting a certain (hopefully small) percentage of lives and property at risk, however there are no requirements tocalculate or report these assumptions such that designers, owners, users and AHJ’s can take this into account in theirwork.A fire load calculation should be based solely on the maximum anticipated energy release from combustibles expected

to be in the building and/or compartment. This methodology should also take into consideration unexpected conditionsthat may increase the fire load beyond what would be normally expected (ref. Station Night Club Fire). This standard aswritten fails to accomplish this.It is my opinion that this standard needs to be carefully reviewed by recognized fire protection industry experts and

testing carried out to validate the methodology in order to address the above concerns.Finally – relying on the Building Owner and the AHJ to monitor the established maximum building fire load and

continue to document it every 5 years (Section 8.6) is impractical. AHJ’s do not have the resources to enforce this nor isit likely that most have the specialized knowledge to properly evaluate the submitted analysis. This would establish anunenforceable and dangerous condition.

_______________________________________________________________________________________________Justin B. Biller, Roanoke County Office of Building Safety

557-8NFPA’s BCDC asks the Technical Committee to Accept in Principle the proposal as revised:

Documentation shall be prepared by an analyst. The analyst shall have a working knowledge ofapplicable building and fire regulations, be competent in the application of scientific and engineering principles relatedfire hazards, risks and understand the impact of fire and effluents on buildings and structures. The engineering analysisand production of technical drawings and calculations shall be prepared by a registered design professional whererequired by statutes of the jurisdiction in which the construction site is located.

Engineering Analysis Documentation. The production of technical drawings and calculations shall be prepared ina manner consistent with the suggestions presented in the SFPE Engineering Guide to Performance-Based FireProtection, and shall contain sufficient information for the AHJ to determine compliance with the design parameters.Add the SFPE Engineering Guide to Chapter 2, Referenced Publications.

Note: This comment was developed by the proponent as a member of NFPA’s Building CodeDevelopment Committee (BCDC) with the committee's endorsement.This comment asks for accept in principle. The change is that references to Registered Design Professional have

been removed. Note for example that NFPA 25 Section 4.1.1.2 states: “Inspection, testing, and maintenance shall beperformed by personnel who have developed competence through training and experience.” Clearly NFPA standardsdo provide minimum requirements for the users of the code to be competent. This comment does not utilizecompetency as outlined in NFPA’s building code.

557-7NFPA’s BCDC asks the Technical Committee to Accept the original proposal.

Note: This comment was developed by the proponent as a member of NFPA’s Building CodeDevelopment Committee (BCDC) with the committee's endorsement.This standard appears to only provide measurements in metric SI units. The original proposal was simply to address

that this standard was only presented in metric SI units, in accordance with the Manual of Style section 4.1. To beconsistent with other NFPA documents, such as NFPA 5000, the system of measurement should be identified, seeNFPA 5000, Section 1.6.2.

557-11NFPA’s BCDC asks the Technical Committee to Accept in Principle the proposal as acted on by

the Technical Committee but revising section 5.1.2.3 as follows:Prior to a change in use or occupancy, the building owner shall evaluate the fire load for in the new use or

occupancy.Note: This comment was developed by the proponent as a member of NFPA’s Building Code

Development Committee (BCDC) with the committee's endorsement.The BCDC agrees with committee member Mr. Koffel’s negative comment is correct. The “use” of a particular

occupancy can change without changing the occupancy classification and still change the fire load and risk to thefacility. The charging statement should include changes in occupancy and changes in use of the occupancy. Webelieve this is the intent of Mr. Boverman’s proposal.

the Technical Committee but revising section 5.1.2.4 as follows:Revise committee action as follows:

Note: This comment was developed by the proponent as a member of NFPA’s Building CodeDevelopment Committee (BCDC) with the committee's endorsement.The BCDC agrees with committee member Mr. Koffel’s negative comment is correct. The “use” of a particular

occupancy can change without changing the occupancy classification and still change the fire load and risk to thefacility. The charging statement should include changes in occupancy and changes in use of the occupancy. Webelieve this is the intent of Mr. Boverman’s proposal.

In the absence of specific information for an item, for cellulosic materials without a wood structure, it shall beacceptable to use a value of 17 MJ as the heat of combustion. In the absence of specific information for an item, forother materials of unknown composition or known not to have been fire retarded, it shall be acceptable to determine thefire load for that item by multiplying the mass of the item by a heat of combustion of 40 MJ/kg.Omit Section 7.5.4.

15 MJ/kg is not a conservative heat of combustion for general fire retarded materials, 40 MJ/kg isappropriate for both retarded and unretarded materials. In point of fact, it is not possible to identify FR materials during asurvey anyway.See for example “The Effectss of FR Agents on Polymer Performance” by V. Babrauskas in .

Heats of Combustion of FR materials range up to 35 MJ/kg,while non FR materials range up to 38 MJ/kg. 40 MJ/kg isthe correct bounding value for both FR and non FR.. If there is specific information on the material, then the publishedheat of combustion can be used per 7.5.1.

In the absence of specific information for an item, for products materials known to exhibit superior fireperformance to that of a standard non fire retarded material, for example as demonstrated by compliance with one of thestandard fire tests shown in the following sections, be fire retarded as demonstrated by standard fire tests as required bythe applicable code, it shall be acceptable to use a value of 15 MJ/kg as the heat of combustion.7.5.4.1 It is the responsibility of the user of section 7.5.4 to demonstrate that any product to which this section is

applied has complied with the corresponding fire test requirement.7.5.4.2* Products that have complied with the fire tests required by NFPA 90A, Standard for the Installation of

Air-Conditioning and Ventilating Systems, or by the applicable mechanical code, for use exposed in plenums shall bepermitted to use a value of 15 MJ/kg as the heat of combustion.7.5.4.3* Upholstered furniture or mattresses that have complied with the fire tests required for such products by

Chapter 10 of NFPA 101, Life Safety Code, or by the applicable fire code, and have done so without the use of barriers,shall be permitted to use a value of 15 MJ/kg as the heat of combustion.7.5.4.4* Electrical or optical fiber wires and cables that have complied with the fire tests required for use in risers

(vertical runs in a shaft or from floor to floor) or in plenums (ducts, plenums, and other spaces used for environmentalair) as required by the National Electrical Code, NFPA 70, shall be permitted to use a value of 15 MJ/kg as the heat ofcombustion.7.5.4.5* Materials or products that have complied with the requirements of limited combustible materials in accordance

with NFPA 101, Life Safety Code, shall be permitted to use a value of 8.141 MJ/kg as the heat of combustion.7.5.4.6* Wood products that comply with the requirements of the applicable building code or fire code for classification

as fire retardant treated wood products shall be permitted to use a value of 10 MJ/kg as the heat of combustion.A.7.5.4 It is important to point out that the simple addition of a small amount of fire retardants to a material is

insufficient to cause the material or product to exhibit a significant change in heat release or effective heat ofcombustion. It is also essential to note that, while some plastics can exhibit heats of combustion of up to 40 MJ/kg,adequately fire retarded materials or materials with inherently improved fire performance, have been shown to exhibitheats of combustion as low as 6-8 MJ/kg. However, it is compliance with the regulatory fire test that is the availableinformation and not data on heats of combustion. It should also be pointed out that the emission of smoke or of toxic orcorrosive products, although important in terms of fire hazard assessment, is not relevant to the calculations to be madein this standard.A.7.5.4.2 NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, requires that the

following materials or products exposed to the airflow in plenums comply with certain the indicated fire tests.Electrical wires and cables and optical fiber cables must be listed as having a maximum peak optical density of 0.50 orless, an average optical density of 0.15 or less, and a maximum flame spread distance of 1.5 m (5 ft) or less whentested in accordance with NFPA 262,

557-27NFPA’s BCDC asks the Technical Committee to Accept in Principle the proposal as follows:

Revise the proposed section as follows:Building codes such as NFPA 5000, Building Construction and Safety Code, and standards like ASCE/SEI 7,

Minimum Design Loads for Buildings and Structures, make reference to determining fire loads for structural evaluation,which include provisions for developing performance based analysis based on fire protection engineering criteria. Inaddition performance based design procedures stipulated in NFPA 5000, NFPA 101 and other performance codes alsorely on design fires for analysis. This standard will provide analytical procedures to establish the fire load requirementsthat will be used as a design tool in determining the overall fire performance of building elements under loadingconditions.

Note: This comment was developed by the proponent as a member of NFPA’s Building CodeDevelopment Committee (BCDC) with the committee's endorsement.This annex material will assist the design professional to understand the application of this standard. This comment

takes into consideration the Committee Statement regarding the second sentence of the original proposal, which wastoo limiting.
