Public Input No. 18-NFPA 664-2014 [ Section No. 1.1.1 ]

1.1.1

Woodworking and wood processing facilities shall include, but are not limited to, wood flour plants,industrial woodworking plants, furniture plants, plywood plants, composite board plants, lumber mills, andproduction-type woodworking shops and , carpentry shops , and instructional wood-workinglaboratories that are incidental to facilities that would not otherwise fall within the purview of thisstandard.

Statement of Problem and Substantiation for Public Input

There are many accounts of fires in wood-working shops in high schools and college settings. NFPA 45 has addressed hazardous laboratories by requiring 1-hour separation between an instructional laboratory in an educational occupancy and the remainder of the facility. By including this type of use in the scope comment, 6.2.1.2 will be applicable and 1-hour separation will be required between a wood working facility in a school and the remainder of the school.

Committee Statement

Resolution: The submitter states that there are many accounts of fires in high school and college woodworkingshops. This has not been substantiated. If the recommended change was accepted as submitted itwould apply to all high school and college woodworking shops which would conflict with theprovisions of 1.1.2. The requirement of 6.2.1.2 applies to all facilities that are covered under 1.1.2.

5.1.4 Maintenance of the Design Features.

To continue meeting the performance goals and objectives of this standard, the design features required foreach hazard area shall be maintained for the life of the facility. This shall include complying with originallydocumented design assumptions and specifications. Any variation from the design shall require approval ofthe authority design professional and the authority having jurisdiction prior to actual change.


The design professional is responsible for the overall plan. It is important that the design professional agree with changes being made to the plan. A good example is the design change that occurred to the skywalk in Kansas City that collapsed, with devastating effects. In that case, a change was made to the plan that the design professional was unaware. Written permission from the design professional is needed for verification. This is similar to a proposal to NFPA 15, PI #20 to section 8.2.1.2.

Where required, draft curtains shall extend down from the roof deck finished ceiling a minimum depth of 10percent of the floor-to-ceiling height and shall fit tight tightly against the roof deck finished ceiling .


The roof deck may not be the lowest point from which a draft curtain must extend. It could be a floor deck, framed ceiling or suspended ceiling. This clarifies the issue by utilizing the term “finished ceiling”. The change from “tight” to “tightly” is editorial.

Adding the term “solid” provides clarification because some structural members, such as open web joists, that have openings and would not act as a draft curtain. The depth requirement is deleted because it is already set forth in section 6.4.3.2. There is no need to repeat it. Additionally, the depth requirement in 6.4.3.3 is worded differently than in 6.4.3.2 hence the proposed revision to 6.4.3.2.

I believe these sections are currently mis-numbered and were intended to be sub-paragraphs of 8.2.2.2.3.

Emergency Nature: As it reads currently, one could misconstrue it as requiring explosion vents on all ducts - regardless of dust concentration. In previous editions of 664, duct protection was required only when approaching the MEC. The TIA fixes an error or omission that was overlooked during the regular revision process and constitutes emergency nature in accordance with 5.3(a) of the Regulations Governing the Development of NFPA Standards.

8.2.2.4.2

Fans and blowers shall be located in one of the following locations:

(1)

(2)

(3) Upstream of the dust collector when the material being conveyed has a moisture content of less than25 percent (wet basis) and a concentration of sub-420 micron particulate (less than 25 percent of theMEC) and the duct downstream of the fan is equipped with a listed spark detection extinguishingsystem and an abort gate to divert material to a safe location

(4) Upstream of the dust collector when the material being conveyed has a moisture content of less than25 percent (wet basis) and a concentration of sub-420 micron particulate (in excess of 25 percent ofthe MEC) and the duct and dust collector are equipped with either deflagration relief venting ordeflagration suppression systems

(5) Upstream of an enclosureless dust collector, regardless of the moisture content or particulate size ofthe material being conveyed

(6) Upstream of outdoor cyclone collectors receiving knife planer shavings, when the fan and the cycloneare located outdoors and exhaust to outdoor atmosphere


The requirement of dust concentration in the duct of < 25% of MEC aready significantly lower the risk for the fan being able to ignite the submicron dust. the spark detection system is an early warning device should the fan be contributing to generate competent igniters and the standard operation of the spark detection and extinguishment system provides for safe handling of a potential developing risk. The use of the abort gate upstream of the AMS is common in the board plants due to higher risk of generating competent igniters in the upstream process and for this or similar industry segments it is a proper solution. However the requirement should not be applied to the rest of the industry with very low posibility of generating competent igniters. The spark detection and extinguishment system provides the protection.

(3) AMS with fire hazards must be equipped with a secondary detection downstream of the AMS andupstream of the abort gate.


Most incidents develop as a fire incident without entering the deflagration stage and therefore make a pressure activated protection system inefficient. The can cause flame fronts to enter occupied areas.With the combination of pre-deflagration detection and the non-deflagration concentration in the pnumatic transport system the spark detection system with detect competent igniters before they enter the AMS whre deflagration concentrations may exist. The abort gate will be in the aborted position should a deflagration incident happen.

A.3.3.14 Explosion. For the purposes of this standard, the term explosion is equivalent to the termdeflagration as identified in NFPA 68, Standard on Explosion Protection by Deflagration Venting.


The words explosion and deflagration are used interchangeably throughout the standard. (The proposed appendix language is used in NFPA 654:A3.3.8. NFPA 654 defines deflagration and explosion with the same verbiage as NFPA 654.)

A.8.2.2.2.3(1)

High-pressure conveyance lines (blowpipes) made of steel or iron pipe with Schedule 40 or greater wallthickness normally meet the strength requirement of 8.2.2.2.3 (1). Administrative controls such aslockout/tagout or inspection programs to ensure that access hatches are in place before equipment isoperated are recommended.

A.8.2.2.2.3(2)

The manufacturer of the listed explosion suppression system should be consulted to determine themaximum reduced deflagration pressure to be expected with their protection hardware. Welded steel of12-gauge minimum thickness is normally strong enough to prevent failure during an explosion, especiallyfor small ducts.

A.8.2.2.2.3( 3)

Deflagration relief vent design with relief pipes and reduced deflagration pressure guidelines are found inNFPA 68, Standard on Explosion Protection by Deflagration Venting . Welded steel of 12-gauge minimumthickness is normally strong enough to prevent failure during a deflagration, especially for small ducts.

A.8.2.2.2.3(4)

Deflagration relief vent design and reduced deflagration pressure guidelines are found in NFPA 68,Standard on Explosion Protection by Deflagration Venting . The manufacturer of the listed flame-quenchingdevice should be consulted to determine the maximum reduced deflagration pressure to be expected withtheir protection hardware.

NOTE: This public input originates from Tentative Interim Amendment 664-12-1 (Log 1119) issued by the Standards Council on March 3, 2014 and per the NFPA Regs., needs to be reconsidered by the Technical Committee for the next edition of the Document.

I believe these sections are currently mis-numbered and were intended to be sub-paragraphs of 8.2.2.2.3.

Emergency Nature: As it reads currently, one could misconstrue it as requiring explosion vents on all ducts - regardless of dust concentration. In previous editions of 664, duct protection was required only when approaching the MEC. The TIA fixes an error or omission that was overlooked during the regular revision process and constitutes emergency nature in accordance with 5.3(a) of the Regulations Governing the Development of NFPA Standards.

A.8.10.4.3

Refer to Section 3-10 Section 2.4.3 of FM 2 7 -8N, Installation of Sprinkler Systems 14, Fire Protection forChemical Plants .


FM 2-8N, Installation of Sprinkler Systems is now obsolete and has been replaced with FM 2-0, Installation Guidelines for Automatic Sprinklers. However the previous reference in section 3-10 of FM 2-8N is now only found in FM 7-14, Fire Protection for Chemical Plants. This reference is to address protection of sprinkler piping, valves and fittings against damage from explosions. It was previously referenced in both FM 2-8N and FM 7-14. However when FM 2-0 was created and FM 2-8N superseded, it was not included.

This was the previous FM 2-8N section 3-10 reference:1. Risers should be located in areas cut off by pressure resistant walls or shielded by structural columns.2. Feed and cross mains should be located away from reactors or pressure vessels insofar as it is practical (e.g., in the aisles or off to the sides of reactors or pressure vessels but never directly above this equipment).3. Generally, water supply mains to hazardous process areas should be buried, looped, and equipped with divisional valves so that any breaks due to explosion damage can be isolated.4. All piping over 2 in.(51mm) should be welded or have welded flanged fittings. Welding should conform to the ANSI standard for pressure piping, B31.1.0 Power Piping. Welded flanged fittings should conform to ANSI Standard B 16.0 Wrought Steel Buttwelding Fittings or B 16.25, Buttwelding Ends for Pipe, Valves, Flanges and Fittings. Welding should be prohibited in an occupied structur; however, welded subassemblies may be prepared outside the area and assembled (flanged) within the areas. Piping 2 in.(51mm) or smaller may be welded; otherwise, malleable iron on steel fittings of 150 lb of steam rating (300 lb W.O.G. rating)should be used. These fittings should conform to ANSI Standard B 16.3, Malleable Iron Screwed Fittings, 150 and 300 lb or B 16.5, Steel Pipe Flanges and Flanged Fittings. Note; Flexible couplings may be used in lieu of welded pipe or welded flanged fittings.5. Piping should be supported from the building or structural framework; however, outdoor piping may be attached to self-supporting process equipment.6. For processing structures located indoors or outdoors, a readily assible manual shuof valve should be provided for each system. All manual sutof valves and automatic sprinkler control valves (alarm check, deluge, etc.) should be located at least 50 ft(15.2m) from the building or structures. Where a greater than average explosion hazard exists, these valves should also be barricaded or located in a dry, readily accessible belowgrade vlave house (manhole-type entrance not acceptable). Also, see Data Sheet 7-14.

This is the reference in FM 7-14 Section 2.4.3:2.4.3.1 Locate risers in areas cut off by pressure-resistant walls or shielded by structural columns.2.4.3.2 Locate feed and cross mains away from reators or pressure vessels (eg., in the aisles or to the sides of reactors or pressure vessels, but never directly above this equipment).2.4.3.3 Bury and loop water supply mains to hazardous process areas. Provide divisional valves so any breaks due to explosion damage can be isolated.2.4.3.4 Ensure all piping over 2 in. (51mm) is welded or has welded flanged fittings. Welding should conform to the ANSI/ASME standard for pressure piping, B31.1 Power Piping. Welded flanged fittings should conform to ANSI/ASME Standard B16.9 Factory-Mde Wrought Steel Buttwelding Fittings or ANSI/ASME STandard B16.25, Buttwelding Ends. Prohibit welding in an occupied structur; however, welded subassemblies may be prepared outside the area and assembled (flanged) within the area. Piping 2 in.(51mm) or smaller may be welded; otherwise, use malleable iron-on-steel fittings of 150 lb steam rating (300 lb W.O.G. rating). These fittings should conform to ANSI/ASME Standard B16.3, Malleable Iron Threaded Fittings, 150 and 300lb; or ANSI/ASME Standard B16.5, Steel Pipe Flanges and Flanged Fittings. Do not use flexible couplings.2.4.3.5 Ensure piping is supported from the building or structural framework. However, outdoor piping may be attached to self-supporting process equipment.2.4.3.6 Provide a readily accessible manual shutoff valve for each system within the processing structure located indoors or outdoors. Locate all manual shuoff valves and automatic sprinkler control valves (alarm check, deluge, etc.) at least 50 ft(15.2m) from the building or structures.
