7. The committee also reviewed the work of the Additive Manufacturing and theReorganization task groups (see below for action items and updates).

8. The Committee is considering adding annex material related to discussion of FMPresentation on inadequacy of current calculations for deflagration venting in NFPA68 for combustible metals depending upon multiple variables.

9. The committee set up a task group to review MEC in dust collection and pneumaticconveying. Questions are: 1) What is appropriate safety factor? 2) Should wereference another source for data? Members are: Sam Rodgers, Jack Osborn, GregCreswell, Greg Super, Brad Burridge, Scott Davis.

10. Reviewed Additive Manufacturing Chapter: Tom Christman to write annex materialprior to second draft meeting concerning bonding/grounding for AM 2.1.2

11. The committee will consider adding a definition for LOC (limiting oxygenconcentration) in Chapter 3.

12. Tom Christman to share generic combustible metals training he has developed withthe Technical Committee.

13. Sam Rogers presented proposed changes to revisit NFPA 68 6.1.2.3*, A.6.1.2.3, andTable A.1.1.3 in the second draft. Mark Drake will contact Laura Moreno, staffliaison for NFPA 68 about the proposed second revisions.

484_CCN_9.pdf 484_CC Note 9

Statement of Problem and Substantiation for Public Comment

The correlating committee requests that the 484 technical committee clearly designate which sections of the standard are meant to be retroactive. Each chapter should designate clearly at the beginning which sections are retroactive. It should also be clearly designated in chapter 1 which sections of the standard are retroactive. Note that the correlating committee is making the same request to the 652 technical committee, and will be addressing this issue with the other standards as well. The goal is to consistently identify retroactive provisions in all of the dust standards.

Type your content here .Create new section 12.2.5 and associated Annex paragraph

12.2.5* Nanoparticle Production by Thermal Spray Pyrolysis

A documented hazard analysis shall be conducted to determine appropriate effective fireand explosion protection measures for combustible metal nanoparticle thermal spraypyrolysis production processes and equipment including the materials coated by thenanoparticles. These measures shall account for possible pyrophoric reactions of thenanoparticles and coating upon suddenly being introduced to an air atmosphere.

Annex Paragraph A.12.2.5 Metallic nanostructured coatings of various materialsincluding paperboard, aluminum foil, and other metals can now be produced by thermalspray pyrolysis processes. One example of this is described in the paper by Makela etal., Aerosol Science and Technology, v. 45, 2011.


Thermal spray nanoparticle coating processes are becoming more common and should be addressed in this section of Chapter 12 along with the other nanoparticle production processes.

11.4.9.4* Dust collection systems for hot metallic nanoparticles shall be inerted unlesscombustibility testing of nanoparticle dust samples demonstrate that the particles are notpyrophoric.

A.11.4.9.4 Hot metallic nanoparticles can be present in welding fumes and dusts produced inadditive manufacturing processes. When these processes involve reactive metals, thenanoparticulate dust cn be pyrophoric.


The new chapter on nanoparticles only covers powders. Potentially pyrophoric metal nanoparticles can also be present in dust from hot reactive metal operations.

The TC should establish if the word "consequential" refers to the consequence of a fire/deflagration in which case the concern is within scope, or "consequential" is not associated with a fire/deflagration event but has anadverse impact, in which case it is outside the document scope.

Public Comment No. 2-NFPA 484-2017 [ Section No. 1.1.6.2 ]

1.1.6.2*

Metal-containing mixtures that also contain combustible nonmetal dusts shall be permitted tobe excluded from this standard and protected according to NFPA 652 and NFPA 654 or otherNFPA industry- or commodity-specific standard, if by testing it is established that the mixturemeets all of the following criteria:

(1) It has been demonstrated that mixture fires can be controlled safely and effectively withClass ABC fire-extinguishing agents.

(2) It has been demonstrated that mixture fires can be controlled safely and effectively withwater.

(3) The material is not a UN Class 4.3 solid as tested using UN Class 4.3 water reactivity testmethods.

(4) It has been demonstrated that the volume resistivity is greater than 1 M ohm-m.

(5) It is not a metal/metal-oxide mixture (e.g., thermite).





The correlating committee requests that the 484 technical committee provide annex material to support the criteria in item (4). It also requests that the 484 technical committee provide annex material to provide guidance to users on how to evaluate items (1) and (2).

Neither definition is consistent with the rules in the English language that have been used for centuries regarding the creation of new words. the fact that predecessors were ignorant of the English language should not justifyperpetuating such ignorance. An explosion is a rupture of an enclosure due to pressure from a deflagration. Therefore, "explosible" means capable of rupturing due to the pressure from a deflagration.

3.3.26* Flash Fire.

A fire that spreads by means of a flame front rapidly through a diffuse fuel, such as dust, gas,or the vapors of an ignitible liquid, without the production of damaging pressure. [921, 2017]





The correlating committee asks that the 484 TC consider this definition with regards to the comments on the ballot, particularly with regard to the term "diffuse fuel". Note that this same suggestion will be made to the 652 TC regarding this definition. It is suggested that the definition in 484 and the other dust documents align with and extract from 652.

9.5.9

Combustible metal dust picked up by a dry fixed vacuum cleaning system shall be dischargedinto a container or collector located outside the building. Wet collector systems shall be inaccordance with 11.4.12.


As written the requirement is somewhat ambiguous regarding wet versus dry collectors. Section 11.4.12 implies that wet collectors are allowed inside the building, as venting is required to terminate outside. 11.4.12.2.2 also requires the ducting to be as short as possible, which implies that the desire is to get the dust into the collector as quickly as possible.
