National Fire Protection Association 1 Batterymarch Park, Quincy, MA 02169-7471 Phone: 617-770-3000 Fax: 617-770-0700 www.nfpa.org MEMORANDUM To: From: NFPA Technical Committee on Handling and Conveying of Dusts, Vapors, and Gases Colleen Kelly, Administrator Technical Projects Date: September 16, 2015 Subject: NFPA 654 Second Draft TC FINAL Ballot Results (A2016) According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot. 29 Members Eligible to Vote 4 Not Returned (Chastain, Cholin, Ebadat, Holcomb) 18 Affirmative on All Revisions (with comment; Febo Jr., Kirby, Reza, Rodgers, Runyon, Taylor, Ural, Walters ) 6 Negative on one or more Revisions (Febo Jr., Frank, Rodgers, Stevenson, Ural, Walters) 1 Abstentions on one or more Revisions (Reza) The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of the vote for each second revision. There are two criteria necessary for each second revision to pass ballot: (1) simple majority and (2) affirmative 2 / 3 vote. The mock examples below show how the calculations are determined. (1) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes are required to pass ballot. (Sample calculation: 20 members eligible to vote 2 = 10 + 1 = 11) (2) Example for Affirmative 2 / 3 : Assuming there are 20 vote eligible committee members and 1 member did not return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample calculation: 20 members eligble to vote 1 not returned 2 abstentions = 17 x 0.66 = 11.22 = 12 ) As always please feel free to contact me if you have any questions.

Second Revision No. 8-NFPA 654-2015 [ New Section after 1.4.3 ] 1.5 Conflicts. 1.5.1 Where a requirement specified in this industry-specific standard differs from a requirement specified in NFPA 652, the requirement in this standard shall be permitted to be used. 1.5.2 Where a requirement specified in this standard specifically prohibits a requirement specified in NFPA 652, the prohibition in this standard shall apply.

This is being added to provide clarity to the user of the document as to how 654 and 652 will interact. Note that the TC changed the term "shall be permitted" in 1.4.2 to "apply". If a provision in 652 is prohibited in 654, the TC believes that the prohibition must apply.

Scherpa, Thomas C. Stevenson, Bill Sutton, Jeffery W. Taylor, Robert D. Thomas, Tony L. Affirmative with Comment Rodgers, Samuel A. While I see this as a step in the correct direction, it is not far enough. Only when 654 provides an equivalent or higher degree of safety than 652 should it be permitted to use the requirement in 654. I agree with Walt that we have done nothing to create a minimum floor until the equivalent or higher degree of safety is mandated. Runyon, Mark L. Agree Ural, Erdem A. This was a change requested by the correlating committee. I was glad when the Standards Council announced restructuring of the dust standards with a fundamentals standard and the formation of a new correlating committee. I thought all dust standards were going to be equally good. I am sad to see the original intent derailed. I sometimes wonder why the correlating committee always votes unanimously on all ballot items, even when the recommendation is to weaken a good standard. I believe it will be helpful for NFPA management to encourage difference in opinions while appointing committee members and setting committee culture. Walters, Michael I agree with Erdem's comment. Also the statements in SR-8 are not as clear as they should be. It refers to 654 as an industry specific standard which it is not. Negative with Comment Frank, Walter L. I still disagree with the concepts outlined in this proposed revision. NFPA 652 was intended to establish the requirements common to all types of dust and all occupancies. While there may be situations where it is valid to waive the requirements of 652, there should be a process for doing so that is more rigorous than "We chose to do so." Exceptions from 652 should be the exception rather than the rule. This revision creates a hole big enough to drive a dump truck through. of 75 9/16/2015 4:29 PM

Although the requirement to perform a dust hazard analysis has been in NFPA 654 for several revision cycles, there are facilities that were constructed prior to the requirement. These facilities will need to conduct a Dust Hazard Analysis per Chapter 7 of NFPA 652. The committee 7 of 75 9/16/2015 4:29 PM
8 of 75 9/16/2015 4:29 PM added these requirements and specified the phase-in period for those facilities that will be newly subject to this requirement to be five years, versus the three years in NFPA 652.

Affirmative with Comment Runyon, Mark L. Agree- Phase in period extension makes sense. Taylor, Robert D. Prefer consistency with NFPA 652 in that there is a three year window to conform with DHA's. While understanding the burden for multi-facility businesses to implement, extending time to complete also increases the likelihood that it will drop from the radar screen as people and business priorities change. If additional time is needed, a variance from the AHJ can be sought. Negative with Comment
Febo, Jr., Henry L. I see no need for extending the implementation of DHA beyond the 3 years specified in 652. This is not a new requirement as PHA of dust hazards appeared in the last 2 editions of 654. Where it is truly impossible to complete, an AHJ exemption could be requested. Frank, Walter L. Three years provided sufficient time to determine whether an area is so dirty that it posed inappropriate levels of risk to facility personnel. Extension of this deadline to 5 years vs 3 is unwarranted. Rodgers, Samuel A. Extension of this deadline to perform a DHA to 5 years from 3 years is unwarranted as NFPA 654 has required similar assessments of all changes for multiple cycles. The exemption for modifications smaller than 25% of the original cost is not justifiable, in general, as this does not relate to the degree of hazard presented by the change. Ural, Erdem A. The new 4.2 language is unacceptable because it will: 1) Give facilities a dangerous exemption from the requirement of performing dust hazard analysis (DHA) until 2021, and 2) Give another dangerous DHA exemption for modifications smaller than 25% of the original cost. Such exemptions may be justifiable, case by case, for certain operations and for small businesses. I am worried that the proposed language will lead to numerous preventable worker injuries and worker deaths. It appears, certain companies and trade associations may think it is cheaper to weaken the Standards by sending their lawyers, lobbyists, and consultants to the committee meetings than to make their workplaces safer. NFPA 654 is a technical committee. I recommend that the NFPA Board of Directors and the Standards Council implement measures to circumvent this problem. Walters, Michael I agree with Walter Frank and Erdem Ural's opposition to this. As a minimum the requirement should agree with the 3 years in 652 for consistency purposes. Also, where did the 25% cost basis for a change. 4.2.1.3 should be omitted. 9 of 75 9/16/2015 4:29 PM
