Related Public Inputs for This Document Related Input Public Input No. 4-NFPA [Chapter C] Relationship Submitter Full Name: Aaron Adamczyk Organization: [ Not Specified ] Submittal Date: Fri Jun 20 00:30:29 EDT 2014 Resolution: The committee appreciates the submitters intention with this public input. Updating the edition dates for NFPA documents, however, is typically a staff or an editorial function. In this case, several of the edition dates are in error and do not reflect what will be the most recent edition of the document when 655 is published.

3 Public Input No. 9-NFPA [ Section No ] * Where lightning protection is provided, it shall be installed in accordance with NFPA 780, Standard for the Installation of Lightning Protection Systems. The proposed annex text provides the user of the standard with information on the source of risk assessment procedures which may be used to determine when lightning protection should be provided. Submitter Full Name: Mark Morgan Organization: East Coast Lightning Equipment Affilliation: On behalf of NFPA 780 References Task Group Submittal Date: Tue Dec 30 17:24:56 EST 2014 Resolution: FR-4-NFPA Statement: The proposed annex text provides the user of the standard with information on the source of risk assessment procedures which may be used to determine when lightning protection should be provided. See attached word file for annex text from PI-10

4 Public Input No. 6-NFPA [ Section No. 5.5 ] 5.5 Fire Fighting Protection for covered liquid sulfur storage tanks, pits, and trenches shall be by one of the following means: (1) Inert gas system in accordance with NFPA 69, Standard on Explosion Prevention Systems (2) * Steam extinguishing system capable of delivering a minimum of 2.5 lb/min (1.13 kg/min) of steam per 100 ft 3 (2.83 m 3 ) of volume Rapid (3.)* Rapid sealing of the enclosure to exclude air. For sulfur tanks and sulfur pits the use of a steam rate of 1.0 lb/min (0.45 kg/min) of steam per 100 ft 3 (2.83 m 3 ) of total tank or pit volume is expected to develop a positive pressure in the enclosure thereby sealing the sulfur tank or sulfur pit preventing air ingress and extinguishing the fire Snuffing Steam and Sealing Steam Precautions The vent systems on enclosed sulfur tanks and sulfur pits must be designed to allow the required snuffing steam rate or sealing steam rate to vent without over pressuring the enclosure. The vent systems must also be designed for proper operation during normal operation Water Extinguishing Precautions Liquid sulfur stored in open containers shall be permitted to be extinguished with a fine water spray Use of high-pressure hose streams shall be avoided The quantity of water used shall be kept to a minimum Dry Chemical Extinguishers. Where sulfur is being heated by a combustible heat transfer fluid, dry chemical extinguishers complying with NFPA 17, Standard for Dry Chemical Extinguishing Systems, shall be provided. The NFPA 655 snuffing steam rate is so large that it creates issues with overpressureing sulfur tanks and sulfur pits. We have written a paper called M olten Sulfur Fire Sealing Steam Requirements to address the problemsfound, present our analysis of the issues and propose a sealing steam rate that we want NFPA 655 to consider Submitter Full Name: ALAN MOSHER Organization: Black & Veatch

5 Submittal Date: Fri Dec 19 18:07:32 EST 2014 Resolution: FR-5-NFPA Statement: This first revision is in response to PI -6 and PI -7. The committee added annex material to (3) to address the submitter's concerns about over pressurization by steam extinguishing systems in (2). This gives the user additional guidance on how to implement the option presented in (3). The committee added additional information in from PI-6 on snuffing steam and sealing seam precautions with modifications to the language to make it enforceable. The annex material from PI-7 has also been added to this first revision, with some minor modifications by the technical committee.

6 Public Input No. 5-NFPA [ Section No ] Dry Chemical Portable Fire Extinguishers. Where sulfur is being heated by a combustible heat transfer fluid, dry chemical extinguishers complying with NFPA 17, Standard for Dry Chemical Extinguishing Systems, water mist extinguishers rated 2-A:C, shall be provided. Dry chemical extinguishers can disrupt a sulfur pile and cause the dust to become airborne, which can explode on contact with an ignition source such as a spark or flame. Water mist extinguishers deliver a fine spray which ensures that sulfur dust clouds are not created. Water mist is also the most satisfactory extinguishing agent for bulk stores. Submitter Full Name: Jennifer Boyle Organization: Mark Conroy, Brooks Equipment Affilliation: Fire Equipment Manufacturers Association (FEMA) Submittal Date: Wed Dec 10 10:05:04 EST 2014 Resolution: The technical committee does not agree with the proposed change. The current requirement is for the use of a dry chemical system, not portable extinguishers. The committee feels that portable extinguishers would be less protective than a fire protection system. In addition, the submitter has not provided any documentation of their claim that dry chemical systems present a hazard. The submitter is encouraged to submit a public comment at the second draft phase that would provide additional documentation of the hazard.

7 Public Input No. 10-NFPA [ New Section after A ] A NFPA 780, Annex L.6 and IEC provide methods for assessments to determine the need for lightning protection. The proposed annex text provides the user of the standard with information on the source of risk assessment procedures which may be used to determine when lightning protection should be provided Submitter Full Name: Mark Morgan Organization: East Coast Lightning Equipment Affilliation: On behalf of NFPA 780 References Task Group Submittal Date: Tue Dec 30 17:26:36 EST 2014 Resolution: See FR-4 for new annex material addressing this public input.

8 Public Input No. 7-NFPA [ Section No. A.5.5.1(2) ] A.5.5.1(2) The steam should preferably be introduced near the surface of the molten sulfur. See NFPA 86, Standard for Ovens and Furnaces, Section F.3. A.5.5.1(3) For enclosed sulfur tanks or sulfur pits with air sweep systems, the sealing steam should be fed into the enclosure very near the air inlets. As the sealing steam vents backwards through the air inlets the sealing steam will quickly stop air ingress to the fire. Sealing steam should be fed into the sulfur tank or sulfur pit for a minimum of 15 minutes or until the temperature has returned to near normal. For further information and good engineering practice regarding sealing steam see Molten Sulfur Fire Sealing Steam Requirements. This is additional information for 6-NFPA System is not letting me link the input forms together. Submitter Full Name: ALAN MOSHER Organization: Black & Veatch Submittal Date: Fri Dec 19 18:23:43 EST 2014 Resolution: See FR-5 for incorporation of this proposed annex material.
