Public Comment No. 3-NFPA 110-2017 [ Section No. 5.2.1 [Excluding any Sub-Sections]
]
Energy converters shall consist only of rotating equipment as indicated in 5.2.4, or fuel cells as described inNFPA 852, Standard for Installation of Stationary Fuel Cell Power Systems .
Statement of Problem and Substantiation for Public Comment
Summary: To address the coordination of NFPA-70, NFPA-99 and NFPA-110, NFPA-110 should be changed to permit fuel cells as source of emergency power provided specific conditions are met.
Originally Proposed Changes to the Code:The following proposed changes were submitted by Walt Vernon during the public comment period on NFPA-110 as one way to permit fuel cells as a source of emergency power in NFPA-110 (Public Input #62 and Public Input #61 respectively):1. Change 5.2.1 to read: “Energy converters shall consist only of rotating equipment as indicated in 5.2.4, or fuel cells as described in NFPA 852, Standard for Installation of Stationary Fuel Cell Power Systems.
2. Additions to section 5.4 as follows: 5.4.1 Because Fuel Cells cannot come up to rated load within a reasonable time,
5.4.1.1. Fuel cell installations must consist of N+1 units operating in parallel, and continuously supplying power to the Emergency System.
5.4.1.2 Fuel cell installations shall have a normal utility supply available in case of total system failure. And
5.4.1.3 Fuel cell installations shall include a connection for portable diesel generator to supply the legally required life safety loads.
These changes were submitted to ensure coordination with NFPA-99 and NFPA-70 both of which permit the use of fuel cells for emergency power.
Committees initial Response:
The NFPA110 committee rejected these changes indicating that “currently fuel cells do not meet all of the performance requirements of NFPA 110.”
New Comment:The committee response in resolving PI 61 was that “fuel cells do not meet the requirements of Section 5.4.” The response to PI 62 was that “currently fuel cells do not meet all of the performance requirements of NFPA 110.” That is exactly what these proposals are trying to address and that resolution statement given by the committee on PI 61 and PI 62 do not address why the committee decided to reject this submittal.
We therefore suggest that the following be added to the text as section 5.4.1:5.4.1 Fuel cells shall be considered to meet the requirement of 5.4 where all of the following conditions are met: (1) Fuel cell installations consist of N+1 units operating in parallel, and continuously supplying power to the Emergency System. (2) Fuel cell installations have a normal utility supply available in case of total system failure. (3) Fuel cell installations include a connection for portable diesel generator to supply the legally required life safety loads.Additionally, section 5.2.1 should be modified as originally suggested, namely: Energy converters shall consist only of rotating equipment as indicated in 5.2.4 or fuel cells as described in NFPA 853, Standard for Installation of Stationary Fuel Cell Power Systems.

It does not appear the committee addressed the fact that fuel cells are already permitted as emergency power sources in other NFPA documents. The committee should further consider the change to ensure proper coordination between all NFPA codes.
Walt Vernon chaired the electrical systems committee for NFPA-99 at the time fuel cells were introduced for inclusion as a source of emergency power for health care facilities. He has indicated he would be happy to work with the NFPA-110 committee to ensure the NFPA-110 is appropriately changed to include fuel cells.
NFPA-99 has jurisdiction over healthcare:NFPA-99 was intended to have jurisdiction over healthcare facilities. Section 1.3.1 indicates that “This code shall apply to all health care facilities other than home care and veterinary care.” Section 1.2 states that “the purpose of this code is to provide minimum requirements for the installation, inspection, testing, maintenance, performance, and safe practices for facilities, material, equipment, and appliances, including other hazards associated with the primary hazards.”Furthermore, section 2.1 (2) notes “where the requirements of a referenced code or standard differ from the requirements of this code, the requirements of this code shall govern.” NFPA-110 is a referenced standard.
NFPA 99 explicitly recognizes use of fuel cells for emergency powerSection 6.4.1.1.7 permits fuel cell systems to serve as the alternate source for all or part of an essential electrical system under certain conditions. The National Electrical Code (NFPA-70) explicitly recognizes the use of fuel cells for emergency powerNFPA70 Already recognizes Fuel Cells as a source of power for emergency systems. Sections 700.12E speaks to this specifically: 700.12E“(E) Fuel Cell System. Fuel cell systems used as a source of power for emergency systems shall be of suitable rating and capacity to supply and maintain the total load for not less than 2 hours of full-demand operation.Installation of a fuel cell system shall meet the requirements of Parts II through VIII of Article 692.Where a single fuel cell system serves as the normal supply for the building or group of buildings concerned, it shall not serve as the sole source of power for the emergency standby system.”
As well, NFPA-70 section 701.12F speak specifically to fuel cell use for legally required standby systems:701.12F:“(F) Fuel Cell System. Fuel cell systems used as a source of power for legally required standby systems shall be of suitable rating and capacity to supply and maintain the total load for not less than 2 hours of full-demand operation.Installation of a fuel cell system shall meet the requirements of Parts II through VIII of Article 692.Where a single fuel cell system serves as the normal supply for the building or group of buildings concerned, it shall not serve as the sole source of power for the legally required standby system.”
Therefore, for coordination, changes should be made to NFPA-110:To ensure coordination of the NFPA documents, NFPA-110 should be changed to permit fuel cells as source of emergency power.The technical details of such a change can be deliberated to address concerns. However, NFPA-110 should recognize fuel cells as a source of emergency power, given that they are already explicitly permitted as a source of emergency power for healthcare facilities under the jurisdiction of NFPA-99 and are explicitly permitted more generally under NFPA-70.

Section 1.3.1 indicates that “This code shall apply to all health care facilities other than home care and veterinary care.” Section 1.2 states that “the purpose of this code is to provide minimum requirements for the installation, inspection, testing, maintenance, performance, and safe practices for facilities, material, equipment, and appliances, including other hazards associated with the primary hazards.”Furthermore, section 2.1 (2) notes “where the requirements of a referenced code or standard differ from the requirements of this code, the requirements of this code shall govern.” NFPA-110 is a referenced standard.
NFPA 99 explicitly recognizes use of fuel cells for emergency power:Section 6.4.1.1.7 permits fuel cell systems to serve as the alternate source for all or part of an essential electrical system under certain conditions.
The National Electrical Code (NFPA-70) explicitly recognizes the use of fuel cells for emergency powerNFPA70 Already recognizes Fuel Cells as a source of power for emergency systems. Sections 700.12E speaks to this specifically:
700.12E:“(E) Fuel Cell System. Fuel cell systems used as a source of power for emergency systems shall be of suitable rating and capacity to supply and maintain the total load for not less than 2 hours of full-demand operation.Installation of a fuel cell system shall meet the requirements of Parts II through VIII of Article 692.Where a single fuel cell system serves as the normal supply for the building or group of buildings concerned, it shall not serve as the sole source of power for the emergency standby system.”
As well, NFPA-70 section 701.12F speak specifically to fuel cell use for legally required standby systems:701.12F:“(F) Fuel Cell System. Fuel cell systems used as a source of power for legally required standby systems shall be of suitable rating and capacity to supply and maintain the total load for not less than 2 hours of full-demand operation.Installation of a fuel cell system shall meet the requirements of Parts II through VIII of Article 692.Where a single fuel cell system serves as the normal supply for the building or group of buildings concerned, it shall not serve as the sole source of power for the legally required standby system.”
Therefore, for coordination, changes should be made to NFPA-110To ensure coordination of the NFPA documents, NFPA-110 should be changed to permit fuel cells as source of emergency power.The technical details of such a change can be deliberated to address concerns. However, NFPA-110 should recognize fuel cells as a source of emergency power, given that they are already explicitly permitted as a source of emergency power for healthcare facilities under the jurisdiction of NFPA-99 and are explicitly permitted more generally under NFPA-70.

(4) The generator set or charger The charger shall be permanently marked with the following:
(5) Allowable range of battery unit capacity that can be recharged within the time requirements ofTable 5.6.4.2
(6) Nominal output current and voltage
(7) Sufficient battery-type data to allow replacement batteries to be obtained
(8) The battery charger output and performance shall be compatible with the batteries furnished.
(9) Battery chargers used in Level 1 systems shall include temperature compensation for charge rate.
Statement of Problem and Substantiation for Public Comment
Article 5.6.4.7 is speaking to static automatic battery chargers (not prime mover driven chargers), as prefaced in 5.6.4.6. So, we should strike "generator set or" from (4), as it doesn't make sense.

The intent of the submitters PI was to make this more flexible, as many modern digital generator controls have HMI membrane panels that include the switch function. The intent was not to insert the word "mechanical" ahead of the word "switch". Don't think we should require a step backwards with technology.

5.6.5.6 *
All installations shall be provided with at least one remote tamperproof emergency stop switch locatedoutside the room housing the prime mover, where so installed, or elsewhere on the premises where theprime mover is located outside the building.
5.6.5.6.1
The remote manual stop station shall be labeled.
The remote stop should be an option not a mandatory component. I suggest the language in 5.6.5.6 bechanged from "All installations shall be provided with at least one remote tamperproof emergency stopswitch" to "All installation should be proided with at least one remote tamperproof emergenc stop switch"
I don't think it is imperitive in Level 1 applications to have this device installed. The specific operatingprocedure for each facility should dictate the need to incorporate the use of the remote switch. I have 30+years of oerational experience working for hospitals in the Engineering Department, I have yet to see aprocedure in place and staff training on the use of the remote stop switch. I have reached out to numerousmembers of the NFPA 110 committee for feedback on policies or procedures in place at other facilities, Ihave yet to receive any correspondance back with an active procedure that has been implemented. We takethe generation of emergency power very seriously here in NYC area, which is why we commit continuousmanpower for the observation and data collection of the emergency generator while in operation.
I would have difficult time putting together an operational procedure for staff to follow for the implementationof the remote stop switch. We all strive to provide our staff the proper training, tools, education andoperatonal strategy for all of our equipment and systems, yet all my peers I've spoken to have yet to addressthe operational strategy for the remote stop switch for Level 1 applcations.
I would be happy to expound further on the topic and entertain any thought processess to safely implementthe use of the switch that would never jeopardize LIFE SAFETY in our hospital.
Please feel free to contact me if you would like to have further dialogue on the topic.

Public Comment No. 10-NFPA 110-2017 [ Section No. 7.9.13 ]
7.9.13
Automatically actuated valves shall not be permitted in the fuel oil supply or fuel oil return lines for Level 1emergency power supply systems when the fuel supply is directly connected to the prime mover .
7.9.13.1*
Automatically actuated valves shall be permitted in the fuel oil supply or fuel oil return lines between a dayfuel tank and the main fuel tank for Level 1 emergency power supply systems.
A.7.9.13.1
The fuel supply is also a fire risk to the building and the occupants of that building. The main fuel tankprovides fuel for extended use of the emergency power system or to multiple emergency generators. Ifthere is an issue with the fuel delivery system to the day fuel tank, a large quantity of fuel can be fed intothe generator room. This fuel will feed a growing fire in the generator room and can escape the roomcreating a liquid fire hazard in an occupancy not designed for that type of fire hazard.
Statement of Problem and Substantiation for Public Comment
The reliability and availability of the direct fuel supply to a Level 1 emergency power supply system is critical. A properly sized day fuel tank will ensure the emergency power is available when needed.
A properly designed fuel/fire detection system interlocked to an automatically actuated valve between the main fuel tank and day fuel tank will help keep any potential spill and/or fire in the emergency generator room and limit the exposure to the main occupancy of the building. With an alarm system, personnel at the facility could respond to any potential false alarm and restore the main fuel supply to the day fuel tank long before the day fuel tank is exhausted. The provision of an automatic shut-off valve in the fuel supply lines between the main fuel tank and day fuel tank will not negatively impact the availability or reliability of the fuel supply to the generator.
The concern of a fuel exposure to the main occupancy of a building is real. There are upsets in the generator room that can lead to fuel from the main tank being pumped into the generator room and also escape the room. To date FM Global has had a couple of incident reported that involved fuel escaping the generator room. In one case the fuel entered a hospital. These events have not resulted in a fire but a liquid fuel fire in any occupancy that is not specifically designed for that exposure can be devastating to the occupancy.

Public Comment No. 13-NFPA 110-2017 [ Section No. 8.3.7 ]
8.3.7*
A fuel quality test shall be performed at least annually using appropriate ASTM standards.
Please see my additions and changes to the current 8.3.7* below as there is much confusion in theindustry due to the broadness of the testing recommendations and information. It would be my privilege toassist in the upcoming editions pertaining to this Chapter and Section.
8.3.7***
A fuel quality test shall be performed no less than annually using appropriate test methods approved underASTM D 975, Standard Specifications for Diesel Fuel Oils, to indicate fuel can be stored for a minimum of1 year without degradation. Not all approved testing under D 975 specifications shall be required, but aminimum testing of Bacteria/Fungi ASTM D6469, Water & Sediment ASTM D2709 and other foreignmaterials shall be performed as where there is a separation of water from the diesel fuel, microbialcontamination can occur. For fuels being stored for periods longer than 12 months, the diesel fuel shallalso be tested for ignition quality and performance by testing for a minimum of Cetane Index ASTMD4737 approved under ASTM D 975 standards.
Additional tests chosen should be recommended on several factors including but not limited to thefollowing:
1) Geographical location and climate in which diesel fuel is being stored. Climates where thetemperature does not get below freezing should not require the testing of the diesel fuels cold weatherproperties such as cloud point, pour point, and cold filter plug point.
2) The environment in which the fuel stored. See points referenced in Annex A 7.9.1.2 which suggestthat fuel degradation accelerates in tanks subjected to temperature variations as it can lead to thepresence of water and where there is a separation of diesel fuel and water microorganisms and fungi cangrow and contaminate the fuel supply which can lead to general or pitting corrosion of steel tanks andcomponents, possibly resulting in filter plugging, operational issues or a hydrocarbon release to theenvironment.
3) The material of the tank in which the fuel stored. See points referenced in Annex A 7.9.3.1 that states"Copper can promote fuel degradation and can produce mercaptide gels. Zinc coatings can react withwater or organic acids in the fuel to form gels that rapidly plug filters.” Tanks with copper and zinc materialcould recommend having Copper Corrosion testing performed by methods approved under ASTM D 975specifications.
4) ASTM D 975 specification allows biodiesel concentrations up to 5% (B5) in diesel fuel with noseparate labeling required at the pump. It is recommended to test for % Biodiesel Concentration ASTMD7371 in a fuel supply being stored for a minimum of 6 months as biodiesel blends are comprised oforganic substances which accelerate the degradation of fuel if not properly treated. Acceleration is greaterwith any presence of microbiological growth and could possibly lead to sludge like substances within thefuel supply leading to clogged filters and operational issues.
5) All diesel fuel tanks filled after 2014, when the ULSD diesel fuel was made required for all NRLMengines and equipment, it is recommended to test for the Sulfur Content ASTM D2622 to ensure allstored fuels meet the current USLD requirement which reduced Sulfur Content to 15ppm.
Additional documentation suggested to be added from the NFPA 25 - Standard for the Inspection, Testing,and Maintenance of Water-Based Fire Protection Systems—2017 Edition is as follows:
1) If diesel fuel is found to be deficient in the testing required in 8.3.7, the fuel shall be reconditioned orreplaced, the supply tank shall be cleaned internally, and the engine fuel filter(s) shall be changed.
2) After the restoration of the fuel and tank, the fuel shall be retested every 6 months until experienceindicates the fuel can be stored for a minimum of 1 year without degradation beyond that allowed in abovechapters.

As a provider of diesel fuel testing predominately within the power generation industry, I believe the clarification and guidelines within the fuel quality testing requirements would eliminate much confusion and inconsistency nationwide, particularly when it comes to critical and emergency power operations. As a member of several associations and hundreds of customers, I have experienced that lack of guidance and education is largest and most consistent challenge in the field not only at the service level but especially at the end user level. In addition, it would certainly assist other regulatory firms that reference the NFPA110 regulations in understanding what to look for when enforcing the requirements within their jurisdiction.
