Report on Proposals – June 2014 NFPA 5000_______________________________________________________________________________________________5000- Log #265 BLD-BLC

_______________________________________________________________________________________________Jeffrey M. Hugo, National Fire Sprinkler Association, Inc.

Add a new section to read:Every building shall have a water supply available to the premises that is capable of producing the

required fire flow as calculated in accordance with NFPA 1 for the required duration as determined by NFPA 1.Builders and developers need to provide sufficient water for fighting a fire at the buildings that they

construct. The fire department should not be responsible for bringing water with them to fight a fire. In rural communitieswithout public mains and hydrants, stored water needs to be available to fight fires. In communities with water utilitiesand fire hydrants, sufficiently sized mains need to be placed in service to provide reasonable fire flow. Section 18.4 ofNFPA 1 provides a method for determining the required fire flow and duration for all properties. This procedure needs tobe followed and implemented when a building is being constructed and the beginning of Chapter 7 brings the issue tothe beginning of the design.

_______________________________________________________________________________________________5000- Log #93 BLD-BLC

_______________________________________________________________________________________________Marcelo M. Hirschler, GBH International

Add text to read as follows:7.1.4.3* . A listed wood product impregnated with chemical by a pressure process or

other means during manufacture, which complies with the requirements of ASTM E2786.ASTM has now issued a test method, ASTM E2768, which contains the three requirements discussed

in this section, namely that a product be tested in accordance with ASTM E84 or UL 723, and exhibit a flame spreadindex of 25 or less, show no evidence of significant progressive combustion when the test is continued for 30 minutes(i.e. an additional 20-minute period over the standard ASTM E84 duration of 10 minutes) and that the flame front notprogress more than 101/2 feet (3200 mm) beyond the centerline of the burners at any time during the test. This changereplaces the lengthy information about requirements with a reference to the standard.The NFPA Manual of Style does not allow requirements in definitions. Therefore this change places the requirementsinto a new section in Chapter 7, immediately following the requirements for noncombustible material and limitedcombustible material.

_______________________________________________________________________________________________Scott J. Harrison, Marioff Inc.

Revise text to read as follows: When buildings are protected throughout with an approved automatic sprinkler system that is installed in

accordance with NFPA 13, ; NFPA 13D,, or NFPA 13R,

, or an approvedautomatic water mist system installed in accordance with NFPA 750, ,the distance shall be permitted to be increased to 450 ft (137 m). [ 18.2.3.2.2.1]

Water Mist systems have been approved and installed in many sprinkler applications globally for over15 yrs. They have been listed by national and internationally recognized testing laboratories such as: (OrdinaryHazard Group 1 occupancies), (Light Hazard occupancies, Computer Rooms, Subfloors, Special Hazard Machinery& spaces), (Light Hazard Occupancies, Combustion Turbines, Machinery Spaces),(Light Hazard, Ord Haz Grp I,II parking garages & III selected occupancies, Cable Tunnels), (Light Hazard,Ord Haz Grp I, Combustion Turbines) and other agencies. These listings and installations have demonstratedequivalent fire protection to the authority having jurisdiction (AHJ). The addition of the proposed text will provide theAHJ a clear option to accept water mist systems as an equivalent system to an approved automatic sprinkler systemthereby allowing construction alternatives without having to prove equivalency or be considered an alternativeextinguishing system.

_______________________________________________________________________________________________5000- Log #256 BLD-BLC

_______________________________________________________________________________________________Dennis L. Pitts, American Wood Council

Revise to read:Type IV (2HH) construction shall be that type in which fire walls, exterior walls, and

interior bearing walls and structural elements that are portions of such walls are of approved noncombustible orlimited-combustible materials except as allowed for exterior walls in 7.2.5.6.7. Other interior structural elements, arches,floors, and roofs shall be of solid or laminated wood or cross-laminated timber without concealed spaces and shallcomply with the allowable dimensions of 7.2.5.5.

Cross-laminated timber (CLT) is a new technology developed in Europe. It is generally analogous tolarge section members currently associated with heavy timber in the current code. Its fire performance is most like thatof glued-laminated beams, or glu-lams, in traditional Type IV (2HH) (heavy timber) construction. Therefore it isproposed that the CLT be included in Type IV (2HH). To properly accomplish this, several proposals are beingsubmitted to add a definition of CLT, add a consensus-developed product standard and then modify the text of Type IV(2HH) to accommodate CLT.More information on the cross-laminated timber product can be found at our website, www.AWC.org.


Page 24 of 53



Revise to read:All dimensions in 7.2.5.5 for solid sawn members shall be considered nominal. The net finished dimensions of

glued-laminated members shall be equivalent to the nominal dimensions of solid sawn timbers. Cross-laminated timberdimensions shall be actual dimensions.

Cross-laminated timber (CLT) is a new technology developed in Europe. It is generally analogous tolarge section members currently associated with heavy timber in the current code. Its fire performance is most like thatof glued-laminated beams, or glu-lams, in traditional Type IV (heavy timber) construction. Therefore it is proposed thatthe CLT be included in Type IV (2HH). To properly accomplish this, this proposal adds a definition of CLT, adds aconsensus-developed product standard and then modifies the text of Type IV (2HH) to accommodate CLT.This proposal is intended to clarify dimensions for solid sawn and glued-laminated timbers. CLT timbers are added.

Revise to read:Floors shall be constructed of spline without concealed spaces and shall be permitted to be of the

Individual timbers shall be fastened to one another. Cross-laminated timbers shall be permitted tobe connected to walls without shrinkage gaps provided dimensional changes are considered in design.

Cross-laminated timber (CLT) is a new technology developed in Europe. It is generally analogous tolarge section members currently associated with heavy timber in the current code. Its fire performance is most like thatof glued-laminated beams, or glu-lams, in traditional Type IV (heavy timber) construction. Therefore it is proposed thatthe CLT be included in Type IV (2HH). To properly accomplish this, this proposal adds a definition of CLT, adds aconsensus-developed product standard and then modifies the text of Type IV (2HH) to accommodate CLT.CLT floors are slightly different than HT so it is put into a separate subparagraph with its own requirements. Among

the differences is thickness (CLT=4 inches; HT=3 inches topped with a sheathing).

The NFPA BLD-BLC committee had organized

a task group with the goal to review and provide

recommendations in regard to the disposition of

Section 7.2.3.2.14 “Ceiling Cavity Plenums and

Raised Plenums.” The subgroup has reviewed

the assignment and is recommending the

following for consideration.

The subgroup recommends that the extracted

NFPA 90A provisions be deleted from Chapter

7 without substitution, and the addition of

language in Chapter 50 be incorporated as part

of our recommendation.

Why?

If we look at NFPA 90A-2012 edition the

subgroup finds that provisions of that standard

represent 19 pages of requirements (Pages 4

through 23) whereas, Chapter 7 contains

approximately 3 pages of extracted text from

NFPA 90A. The question then becomes “Is it

necessary to extract this quantity of text versus

having the user of NFPA 5000 referring to the

entire document?” The subgroup would submit

no since reading NFPA 90A does not represent a

substantial impact to the user.

Is there a need to extract?

The subgroup would recommend no there is not.

The provisions which were originally extracted

appear to have text which has a greater

relationship with NFPA 90A than they do with

NFPA 5000 Chapter 7. While portions of the

extracted text do contain construction and fire

related text, the subgroup recommends that the

above proposal would be more appropriate since

NFPA 90A is recognized as the standard for the

installation of air-conditioning and ventilating

systems.

Is there a need to have NFPA 90A language

in NFPA 5000?

The subgroup would recommend no there is not.

investigated and assigned a fire resistance rating of 1 hour or more, the assembly shall meet the

requirements of 5.3.3. [90A:4.3.11.2.5]

(I) Materials within a ceiling cavity plenum exposed to the airflow shall be noncombustible or comply

cables tested in accordance with NFPA 262, Standard Method of Test for Flame Travel and Smoke of

Wires and Cables for Use in Air-Handling Spaces, are required.

(2) Pneumatic tubing for control systems shall be listed as having a maximum peak optical density

of 0.5 or less, an average optical density of 0.15 or less, and a maximum flame spread distance of 5 ft

(1.5 m) or less when tested in accordance with ANSI/UL 1820, Standard for Safety Fire Test of

Pneumatic Tubing for Flame and Smoke Characteristics. [90A:4.3.11.2.6.2]

(3) Nonmetallic fire sprinkler piping shall be listed as having a maximum peak optical density of

0.5 or less, an average optical density of 0.15 or less, and a maximum flame spread distance of 5 ft (1.5

m) or less when tested in accordance with ANSI/UL 1887, Standard for Safety Fire Test of Plastic

Sprinkler Pipe for Visible Flame and Smoke Characteristics. [90A:4.3.11.2.6.3]

in accordance with UL 2043, Standard for Safety Fire Test for Heat and Visible Smoke Release for

Discrete Products and Their Accessories Installed in Air-Handling Spaces. [90A:4.3.11.2.6.5]

(6) Supplementary materials for air distribution systems shall be permitted when complying with

the provisions of 4.3.3. [90A:4.3.11.2.6.6]

(8) Air ducts complying with 4.3.1.2 and air connectors complying with 4.3.2 shall be permitted.

[90A:4.3.11.2.6.8]

(9) Materials that, in the form in which they are used, have a potential heat value not exceeding

3500 Btu/lb (8141 kJ/kg), where tested in accordance with NFPA 259, Standard Test Method for

Potential Heat of Building Materials, and include either of the following:

As noted in the paragraph above, the subgroup

did not find sufficient cause to suggest that there

was enough language in the extracted language

from NFPA 90A to adequately support that

NFPA 5000 be the preferred location. Further,

the subgroup questioned the impact of this

extraction considering the other relationships in

NFPA 90A with the language that was originally

extracted.

What about NFPA 90A Section 1.3

Application?

Section 1.3 applies to spaces greater than 708

m3 (25,000 ft2), for building construction Types

III, IV and V greater than 3 stories regardless of

volume, buildings and spaces not covered by

other applicable NFPA standards, and occupants

and processes not covered by NFPA standards.

On the other hand NFPA 5000 did not include

those parameters for the applications of

plenums. As a result, the subgroup recommends

that the intent of NFPA continue in spirit with

this proposal with the introduction of the second

sentence in the proposal.

Is the simple reference to NFPA 90A too

broad?

If the BLD committee believes that the proposal

is too broad in its applications, and that as a

result the proposal looses the original intent of

the extracted provisions from NFPA 90A into

Chapter 7 of NFPA 5000, the following might

be considered an a compromise.
