1 National Fire Protection Association 1 Batterymarch Park, Quincy, MA Phone: Fax: MEMORANDUM TO: FROM: Technical Committee on Liquefied Petroleum Gases Kimberly Shea DATE: June 30, 2014 SUBJ: NFPA 58 Proposed TIA No Ballot Results According to 5.4 in the NFPA Regs, the final results show this TIA HAS NOT achieved the ¾ majority vote needed on both Question 1 (Technical Merit) and Question 2 (Emergency Nature). 30 Eligible to Vote 6 Not Returned (Belke, Bogan, Garza-Obregon, Hinske, Kastanas, Meyer) Technical Merit Emergency Nature: 13 Agree 12 Agree 10 Disagree (Fredenburg, Hoffmann, King, Mahnken, Mortimer, Osterhaus, Ribbs, Stainbrook, Wilson, Wolff-Klammer) 10 Disagree (Fredenburg, King, Mahnken, Mortimer, Osterhaus, Ribbs, Stainbrook, Wilson, Wolff-Klammer, Young) 1 Abstain (Barber) 2 Abstain (Barber, Hoffman) There are two criteria necessary to pass ballot [(1) affirmative ¾ vote and (2) simple majority] with both questions needing to pass ballot in order to recommend that the Standards Council issues this TIA. (1) In all cases, an affirmative vote of at least a simple majority of the total membership eligible to vote is required. This is the calculation for simple majority: 30 eligible 2 = = 16 (2) The number of affirmative votes needed to satisfy the ¾ requirement is: Question 1: 30 eligible - 6 not returned - 1 abstentions = = = 18 Question 2: 30 eligible 6 not returned - 2 abstentions = = 16.5 = 17 An appeal relating to a proposed Tentative Interim Amendment shall be filed 5 days after the notice of the Correlating Committee TIA ballot results are published in accordance with (c) and

2 TECHNICAL COMMITTEE LETTER BALLOT Question 1: I agree with the TECHNICAL MERITS of the Proposed TIA to revise and Table AGREE X DISAGREE* ABSTAIN* The arguments presented in the substantiation are more complex than should be allowed in the hurried consideration of a TIA. Much technical information cannot be verified in this brief review. It needs to be researched and discussed. AGREE X DISAGREE* ABSTAIN* The emergency nature cited (5.4 (e)) is not appropriate for this topic. Yes, it is an advance, but not in safeguarding property or life. _Richard Fredenburg June 20, 2014 Please return the ballot to kshea@nfpa.org no later than Thursday, June 19, 2014.

3 Shea, Kimberly From: Richard Hoffmann Sent: Tuesday, June 17, :52 PM To: Shea, Kimberly Cc: Tina Pellegrini Subject: NFPA 58 Comments - Proposed TIA Dear Kimberly Shea I have reviewed the proposed TIA and have several issues with it. 1. the alloy of choice is AA 6061, which is a good alloy. 2. the reported melting point is +1280F. This number represents the end of the melting range, where you have a puddle of aluminum on the bottom where it collected. The melting starts, for this alloy, at about 1080F. the melting would start throughout the alloy, at all low melting point constituents. 3. The use of threaded surfaces as shown in the attached photographs is not good, since aluminum is a poor "threading" alloy and galling / surface corrosion can occur, causing sealing issues on the threads. The counter to this is the mag lite flashlights, which have a good life, but the threading can be difficult. 4. The filter canister is identified as steel there will be a galvanic corrosion issue here with the aluminum being the anode, and corrosion could take place, depending on the environment the component is placed in. The question that I must ask is how long will the canister / filter housing always be steel? or will that someday switch to aluminum. Based on these comments, I cannot accept the technical merits of this proposed TIA. I have no comment on the "emergency" nature of this issue, however, I think it needs more discussion time.

5 TECHNICAL COMMITTEE LETTER BALLOT Question 1: I agree with the TECHNICAL MERITS of the Proposed TIA to revise and Table AGREE X DISAGREE* ABSTAIN* No explanation was given why higher melting point materials cannot be used for the filter heads. AGREE X DISAGREE* ABSTAIN* Why should the standard be lowered to allow use of aluminum filter heads?

This can and should be addressed during a normal cycle. AGREE XX DISAGREE* ABSTAIN* No emergency here. Frank J.

Why not forged, cast, spun aluminum. This appears to be a proprietary submittal. AGREE x DISAGREE* ABSTAIN* This issue does not meet the level emergency. The subject should be vetted at an open TC meeting. Phillip H Ribbs Phillip H Ribbs 6/11/14 1

9 TECHNICAL COMMITTEE LETTER BALLOT Question 1: I agree with the TECHNICAL MERITS of the Proposed TIA to revise and Table AGREE X DISAGREE* ABSTAIN* _The use of aluminum bodies in liquid applications especially in pipelines at bulk plants have always been restricted due to the concerns about heat from fire exposure resulting in the failure of the body and the discharge of product from the failed body making a bad situation worse. There are other materials that are currently approved for liquid applications called out in table that more than likely could be used as a body for this product such as ductile iron, steel, malleable iron and brass to name a few. AGREE X DISAGREE* ABSTAIN* _There is no potential for loss of life, exposure of the public to a hazard or negative effect on over-all industry safety if this is not acted on immediately; this is not an emergency. David Stainbrook 5/5/14 Please return the ballot to kshea@nfpa.org no later than Thursday, June 19, 2014.

11 TECHNICAL COMMITTEE LETTER BALLOT Question 1: I agree with the TECHNICAL MERITS of the Proposed TIA to revise and Table AGREE X DISAGREE* ABSTAIN* If the section is revised to include the entire LP-Gas filtration system, it would also include the housing. This proposal should be for filter heads only. Also in section the minimum melting point of 1500 degrees F would still apply to the filter heads. Section would need to be revised and balloted to add filter heads as an exception. AGREE X DISAGREE* ABSTAIN* A new proposal need to be submitted based on my comments above. Edgar Wolff-Flammer 6/17/2014 Please return the ballot to kshea@nfpa.org no later than Thursday, June 19, 2014.

13 Shea, Kimberly From: Sent: Wednesday, June 18, :03 AM To: Shea, Kimberly Subject: Re: NFPA 58 Proposed TIA Ballot Reminder - Due June 19, 2014 Dear Kimberly, I have carefully considered the proposed TIA, which I fully understand. However as an overseas member of the committee on this occasion I consider it inappropriate to vote, and therefore abstain. For the benefit of the committee members I would like to bring to their attention the following situation relating to the use of aluminium components in LPG systems. I have personal experience of problems which can occur if the LPG is from a refinery which uses caustic soda for the removal of hydrogen sulphide. Any carry over of the caustic soda, if associated with water, causes an aggressive chemical reaction leading to the early failure of any aluminium components in the system. We addressed this problem in the UK by replacing the aluminium components with matching items machined from stainless steel. We worked closely with the UK licensee for Rego on many occasions. Best regards, Don Barber Principal & Senior Partner, Enmat International.
