NFPA 18A Public Comment

Public Comment No. 20-NFPA 18A-2015 [ Global Input ]

I support the development of Class C Fire test Methods. Test should consider the use of agents in

extinguishers, municipal applications and arc suppression for energized electrical fires.


As technology evolves and the demand for power grows; the absence of viable agents for the suppression of class C fires presents an unreasonable risk to life, property and our infrastructure. The lack of safe and effective agents leaves the fire services with no means of an offensive attack for suppression much less a defensive attack to protect exposures. The ability to have agents tested and listed will ensure that fire services and brigades have the best possible solution to these low frequency high hazard incidents. We cannot hope for success; we must prepare for it.

Chapter 8 Class C Fire Test Methods

8.1 General.

Water additive solutions for Class C fires shall be tested and listed in accordance with one ormore of the following test procedures:

Conductivity test

8.1 General


(1) Extinguisher test

(2) Manual Operations test

(3) Arcing Conductor test

8.2 Extinguisher Test

8.2.1 The safe use of water additives in extinguishers to mitigate or suppress a Class Cfire shall be evaluated through the following test method. The test and setup has beeninformed by ANSI / UL 711 requiring a test voltage of 100kV AC to be applied at 48” whichis the minimum approach distance for hazard as defined by OSHA 1910.269 Table R-7found below in Exhibit 8.2.1.a

Exhibit 8.2.1.a

Additional Proposed Changes

File Name Description Approved

OSHA_Table_R.pdf

As technology evolves and the demand for power grows, the absence of viable agents for the suppression of Class C fires presents an unreasonable risk to life and property. The lack of safe and effective agents leaves fire and utility services with no means of an offensive attack, not to mention a defensive attack. Further, waiting for utility response ties up fire resources because these volatile incidents cannot be managed without their support. The fire services need the ability to resolve these large volume weather driven events and return to fire duty.

I strongly support the development of Class C Fire test methods. Tests should consider the use of agents in extinguishers,

Class C Fire Test Methods

8.

1 1 General .

Water additive solutions for Class C fires shall be tested and listed in accordancewith one or more of the following test procedures

:


.





8.2.1 The safe use of water additives in extinguishers to mitigate or suppress a Class C fireshall be evaluated through the following test method. The test and setup has been informed byANSI / UL 711 requiring a test voltage of 100kV AC to be applied at 36” which is the minimumapproach distance for contact hazard as defined by OSHA 1910.269 Table R-7 found below inExhibit 8.2.1.a

Exhibit 8.2.1.a

8.2.3 The pass/fail criterion shall be a maximum measured leakage current below 500uA at36”. As informed by NFPA 70E Standards for Electrical Safety in the Workplace (effects ofcurrent of the human body - 1 mA is the perception threshold level so a leakage half of thatvalue to pass the test is required)

8.2.4 Water additives shall be evaluated for viscosity and surface tension values to determineif the agent pooling will be sufficiently large enough to expand beyond the standoff distancewhich could pose the risk of electrocution. If it is found the agent cannot spread beyond thestandoff distance as stated in the instructions the agent shall not be subjected to theconductivity test required by NFPA 10.

8.2.5 The water additive solution shall be prepared at the manufacturer’s minimum andmaximum recommended concentrations.

8.2.6 Use of these extinguishers should be limited to trained fire fighters, such as fire servicesmeeting the qualifications of NFPA 1001, private brigades who are NFPA 1081 qualified, andElectrically Qualified Workers 1910.332 (b)(3), as defined by OSHA.

8.3 Manual Operations Test

8.3.1 This section of code addresses the ability of water additive solutions to be evaluated foruse in manual firefighting operations to suppress Class C fires or on fires impinged by “Live”electrical sources.

8.3.2 The agent shall be tested with application and mixing hardware specified by the

manufacturer and under the worst case application conditions, including consolidated streamand maximum flow rate.

8.3.3 The test apparatus shall be configured and the agent prepared for application per themanufacturers written instructions

8.3.4 Tests shall be conducted using a solution of water additive made with the concentrate,as received, in fresh water and at the concentration specified by the manufacturer. Wateradditive solutions made with synthetic seawater may also be tested, if such usage is specifiedby the manufacturer.

8.3.5 Tests shall be conducted only when the ambient temperature is above 5°C (40°F) andin still air. If tested outdoors, wind speeds shall be less that 5 miles/hour (8 km/hour).

8.3.6 Testing shall be conducted similarly to UL 711, Rating and Fire Testing of FireExtinguishers , section 9,but scaled for manual firefighting operations using AC or DC.

8.3.7 The 12 inch by 12 inch target shall be replaced with a 138 kV disconnect switch such asused in an electrical substation or other appropriate target for the category voltage. Illustrationbelow is a typical electrical substation disconnect switch.

Exhibit 8.3.7.a

138Kv substation Disconnect switch

8.3.8 The disconnect switch shall be located at the top of the bus bar and energized using apower supply that is capable of supplying the desired test voltage while the insulators isolatethe bus bar from ground.

8.3.9 Disconnect switches designed for target voltages above 138kV, such as 345kV and500kV, are ideal since their designs consider insulation from a ground reference via theinsulators.

8.3.10 A wire shall be inserted into the nozzle to ensure contact is made with the stream ofsolution being tested. The wire shall be attached to ground through a circuit containing twomultimeters in series, The two multimeters shall be set, one each, to read current in milliampsand microamps. The current measurements are to be recorded during each test, afterstabilization of the readings.

Exhibit 8.3.10.a

18a-Section_8_Oct-25.docx


Problem Statement: Currently, NFPA 18a only considers Class A & B fires while Class C fires remain low frequency high hazard incidents. The NFPA fails to support the fire services & utilities with viable agents capable of being used safely and effectively in an electrical environment. In the absence of formal support from NFPA localized R&D work with Con Edison and the FDNY has yielded the solutions provided to you herein. • Extinguishers: Currently, the extinguishers that have a Class C listing can be used in a Class C environment but cannot extinguish a Class C fire. We need to open the door with testing for agents that can suppress an energized fire. In addition, Class A and Class B listings are scalable while Class C is not. We are proposing a Professional Class C rating for use by the fire services, brigades and electrically qualified OSHA workers. We are looking at the use of extinguishers to manage a problem before it becomes an emergency. This can prove to have significant effect in the aircraft and maritime industry. • Manual Suppression: the municipal fire services are tasked with the preservation of life and property. However they remain white knuckled at electrical fires hoping for a favorable outcome because there is no direction in terms of what agents are safe for mitigation/suppression. Due to the lack of viable agents, the fire services cannot even assume a defensive role safely which places substations and power plants at risk from collateral. These incidents can result in large blackouts compromising public safety and the integrity of the electrical infrastructure. . • Arc Suppression: From burning wires to manhole fires these incidents present a significant risk to the general public. These events are mostly weather driven and exceed the staffing capacity of the utility to provide support in a timely manner. Testing will provide the fire services with agents to mitigate the effects of these situations. These weather driven incidents can quickly consume the resources of even the largest fire departments leaving few members available for fire duty thus putting the public at risk.

Public Comment No. 16-NFPA 18A-2015 [ Chapter 8 [Title Only] ]


Class C fire test methods need to be developed. These test methods should consider the use ofagents in extinguishers, applications for municipal operations such as manhole fires, transformerfires (both underground and pole transformers, and arc suppression for these energized electricalfires.


Changes in technology and the demand for power demonstrates the need for viable agents for the suppression of class C fires. Without these new Class C suppression agents there is an increased risk to the first responder, utility worker and the public. This is an unreasonable risk to life, property and our infrastructure. The lack of safe and effective agents inhibits the fire services from initiating an offensive attack for suppression on the source as well as protecting exposures. It is vital to have these new agents tested and listed so the municipal fire services and fire brigades can have the best possible tools to mitigate these hazardous incidents.

Chapter 8

.1 Class C Fire Test Methods

8.1 General .

Water additive solutions for Class C fires shall be tested and listed in accordance with one ormore of the following test procedures

:


.





8.2.1 The safe use of water additives in extinguishers to mitigate or suppress a Class C fireshall be evaluated through the following test method. The test and setup has been informed byANSI / UL 711 requiring a test voltage of 100kV AC to be applied at 36” which is the minimumapproach distance for contact hazard as defined by OSHA 1910.269 Table R-7 found below inExhibit 8.2.1.a

Exhibit 8.2.1.a

8.2.3 The pass/fail criterion shall be a maximum measured leakage current below 500uA at36”. As informed by NFPA 70E Standards for Electrical Safety in the Workplace (effects ofcurrent of the human body - 1 mA is the perception threshold level so a leakage half of thatvalue to pass the test is required)

8.2.4 Water additives shall be evaluated for viscosity and surface tension values to determine ifthe agent pooling will be sufficiently large enough to expand beyond the standoff distancewhich could pose the risk of electrocution. If it is found the agent cannot spread beyond thestandoff distance as stated in the instructions the agent shall not be subjected to theconductivity test required by NFPA 10.

8.2.5 The water additive solution shall be prepared at the manufacturer’s minimum andmaximum recommended concentrations.

8.2.6 Use of these extinguishers should be limited to trained fire fighters, such as fire servicesmeeting the qualifications of NFPA 1001, private brigades who are NFPA 1081 qualified, andElectrically Qualified Workers 1910.332 (b)(3), as defined by OSHA.

18a-Section_8_Oct-25.docx Text with images and tables


The development of Class C Fire test Methods need to be expanded on beyond NFPA 10. Class A and B fires range in size, type and procedure to suit applications however class C is currently only applicable to extinguishers for all to use. Test should consider the use of agents in extinguishers, fixed system applications, and manual operation for both municipal applications, utility personal who face arc suppression for down wires, transformer fires, manhole fires and the protection of other electrical systems. As technology evolves and the demand for power grows; the absence of testing and certification for viable agents for the suppression of Class C fires presents an unreasonable risk to life and property. Without the standardized testing process, certification and recognition by NFPA will make it difficult for professionals to determine a suitable agent. The lack of safe and effective agents leaves the fire services with no means of an offensive attack much less a defensive attack. Waiting for utility response ties up fires resources because these volatile incidents cannot be managed without their support. The fire services need the ability to resolve these large volume weather driven events and return to fire duty.
