Public Input No. 6-NFPA 655-2014 [ Section No. 5.5 ]

5.5 Fire Fighting.

5.5.1

Protection for covered liquid sulfur storage tanks, pits, and trenches shall be by one of thefollowing means:

(1) Inert gas system in accordance with NFPA 69, Standard on Explosion PreventionSystems

(2)

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 pitvolume is expected to develop a positive pressure in the enclosure thereby sealing the sulfurtank or sulfur pit preventing air ingress and extinguishing the fire.

5.5.2 Snuffing Steam and Sealing Steam Precautions

5.5.2.1 The vent systems on enclosed sulfur tanks and sulfur pits must be designed to allowthe required snuffing steam rate or sealing steam rate to vent without over pressuring theenclosure. The vent systems must also be designed for proper operation during normaloperation.

5.5.3 Water Extinguishing Precautions.

5.5. 2 3 .1

Liquid sulfur stored in open containers shall be permitted to be extinguished with a fine waterspray.

5.5. 2 3 .2

Use of high-pressure hose streams shall be avoided.

5.5. 2 3 .3

The quantity of water used shall be kept to a minimum.

5.5. 3 4 Dry Chemical Extinguishers.

Where sulfur is being heated by a combustible heat transfer fluid, dry chemical extinguisherscomplying 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

Committee Statement


Statement: This first revision is in response to PI -6 and PI -7. The committee added annex materialto 5.5.1 (3) to address the submitter's concerns about over pressurization by steamextinguishing systems in 5.5.1 (2). This gives the user additional guidance on how toimplement the option presented in 5.5.1 (3). The committee added additional informationin 5.5.2 from PI-6 on snuffing steam and sealing seam precautions with modifications tothe language to make it enforceable. The annex material from PI-7 has also been addedto this first revision, with some minor modifications by the technical committee.

Public Input No. 5-NFPA 655-2014 [ Section No. 5.5.3 ]

5.5.3 Dry Chemical Portable Fire Extinguishers.

Where sulfur is being heated by a combustible heat transfer fluid, dry chemical extinguisherscomplying with NFPA 17, Standard for Dry Chemical Extinguishing Systems , water mistextinguishers 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.

Committee Statement

Resolution: The technical committee does not agree with the proposed change. The currentrequirement is for the use of a dry chemical system, not portable extinguishers. Thecommittee feels that portable extinguishers would be less protective than a fire protectionsystem. In addition, the submitter has not provided any documentation of their claim thatdry chemical systems present a hazard. The submitter is encouraged to submit a publiccomment at the second draft phase that would provide additional documentation of thehazard.

Public Input No. 7-NFPA 655-2014 [ 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 fedinto the enclosure very near the air inlets. As the sealing steam vents backwards through theair inlets the sealing steam will quickly stop air ingress to the fire. Sealing steam should be fedinto the sulfur tank or sulfur pit for a minimum of 15 minutes or until the temperature hasreturned to near normal. For further information and good engineering practice regardingsealing steam see Molten Sulfur Fire Sealing Steam Requirements.

Date: May 4, 2015

Subject: NFPA 655 First Draft TC Revised FINAL Ballot Results (F2016)

According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot.

30 Members Eligible to Vote 2 Members Not Returned (S. Greeson, T. Scherpa) 27 Members Voted Affirmative on All Revisions (4 w/ comment: L. Floyd, S. Rodgers, M. Runyon, E.

Ural) 1 Member Voted Negative on one or more Revisions (E. Ural) 0 Members Abstained on one or more Revisions The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of the vote for each first revision.

There are two criteria necessary for each first revision to pass ballot: (1) simple majority and (2) affirmative 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 : 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.

Terraview seems to show 4.2.5.3.1 adjustment for threshold layer criterion as "Deleted". This is notconsistent with the layer criterion option, since this adjustment is needed. I believe this is a Terraviewerror and was never a committee intent. No where else to write this comment - Equation B.2a alsoappears "Deleted" in Terraview. Again, this is not the committee intent and it makes no sense to haveExample 1 without the conclusion of that example.

This first revision is in response to PI -6 and PI -7. The committee added annex materialto 5.5.1 (3) to address the submitter's concerns about over pressurization by steamextinguishing systems in 5.5.1 (2). This gives the user additional guidance on how toimplement the option presented in 5.5.1 (3). The committee added additional informationin 5.5.2 from PI-6 on snuffing steam and sealing seam precautions with modifications tothe language to make it enforceable. The annex material from PI-7 has also been addedto this first revision, with some minor modifications by the technical committee.
