ALTERNATIVE CONCEPTS

This appendix chapter provides consideration of the following alternatives: (1) exterior sprinkler systems,
(2) alternative water supply systems for exposure protection, (3) Class A foam systems, (4) enhanced exterior fire protection, (5) sheltering in place, and (6) building location.

Exterior sprinkler systems. Currently, there is no nationally accepted standard for the design and installation of exterior fire sprinkler systems. Interior sprinkler systems are regulated by nationally recognized standards that have specific requirements. However, exterior sprinkler systems lack such

uniformity. What is generally proposed is a type of sprinkler system, placed on the roofs or eaves of a building, whose primary purpose is to wet down the roof. These types of systems can be activated either manually or automatically. However, the contemporary thought on exterior sprinkler systems is that if the roof classification is of sufficient fire resistance, exterior sprinklers are of little or no value.
Another option and alternative with exterior sprinklers is to use them to improve the relative humidity and fuel moisture in the defensible space. In this case, the exterior sprinkler is not used to protect the structure as much as it attempts to alter the fuel situation. However, studies do not support the idea that merely spraying water into the air in the immediate vicinity of a rapidly advancing wildland-urban fire does much good. Clearly, irrigation systems that keep plants healthy and fire-resistive plants that resist convection and radiated heat can accomplish the same purpose.

Alternative water supply systems for exposure protection. Pools and spas are often offered as an alternative water source for fire departments. These water sources must be accessible open for
access and reliable to be of any use by fire protection forces. Accessibility means that the fire department must be able to withdraw the water without having to go through extraordinary measures such as knocking down fences or having to set up drafting situations. Designs have been created to put liquid- or gas-fueled pumps or gravity valves on pools and spas to allow fire departments to access these water systems. A key vulnerability to the use of these alternative water systems is loss of electrical power.
When the reliability of a water system depends on external power sources, it cannot be relied upon by fire fighters to be available in a worstcase scenario.

Class A foam systems. A new and emerging technology is the concept of Class A foam devices. These are devices that allow a homeowner to literally coat the exterior of their house with a thick layer of foam that prevents the penetration of embers and radiant heat to the structure. There is no nationally recognized standard for Class A foam technology; however, experiments in various wildland fire agencies seem to advocate foaming houses in advance of fire and flame fronts. To be accepted by the code official, the Class A foam system should pass rigorous scrutiny with regard to the manner and needs in which it is activated, the ways and means in which it is properly maintained, and a ways and means to test the system for its operational readiness during hiatus between emergencies.

Enhanced exterior fire protection. This alternative method would increase the degree of fire resistance on the exterior of a building. This is most often an alternative recommended as a retroactive application when individual properties cannot achieve adequate defensible space on the exterior of a building.
Normally, fire resistance and building scenarios are concerned with containing a fire. Fire-resistance ratings within building design infers resistance to a fire for the specified time to compartmentalize the building's interior.
To improve fire resistance on the exterior of the structure, the primary emphasis is on preventing intrusion into the building. This means protection of apertures and openings that may or may not be required to have any degree of fire resistance by accepted building codes. The option that is available here is for individuals to provide coverage in the form of shutters or closures to these areas, which, along with maintenance of perimeter-free combustibles, can often prevent intrusion.
There are obvious limitations to this alternative. First and foremost is the means of adequately evaluating the proposed fire resistance of any given assembly. Testing techniques to determine fire resistance for such objects as drywall and other forms of construction may not be applicable to exterior application. Nonetheless, code officials should determine the utility of a specific fire resistance proposal by extrapolating conservatively.

Shelter in place. Developments in the wildland-urban interface may be designed to allow occupants to "Shelter in Place." Use of this design alternative should include ignitionresistant construction, access, water supply, automatic sprinkler systems, provisions for and maintenance of defensible space, and a Fire Protection Plan.
A Fire Protection Plan describes ways to minimize the fire problems created by a specific project or development. The purpose for the Fire Protection Plan is to reduce the burden and impact of the project or development on the community's fire protection delivery system. The plan may utilize components of land use, building construction, vegetation management and other design techniques and technologies. It should include specific mitigation measures consistent with the unique problems resulting from the

location, topography, geology, flammable vegetation and climate of the proposed site. The plan shall be consistent with this code, and approved by the fire code official. The cost of preparation and review is to be borne by the project or development proponent.

Building location. The location of a new building within lot lines should be considered as it relates to topography and fire behavior. Buildings located in natural chimneys, such as narrow canyons and saddles, are especially fire prone because winds are funneled into these areas and eddies are created. Buildings located on narrow ridges without setbacks may be subjected to increased flame and convective heat exposure from a fire advancing from below. Stone or masonry walls can act as heat shields and deflect the flames. Swimming pools and rated or noncombustible decks and patios can be used to create a setback, decreasing the exposure to the structure. Attic and under floor vents, picture windows and sliding glass doors should not face possible corridors due to the increased risk of flame or ember penetration.

2015 International Mechanical Code

[F] 513.12.4 Automatic control. Where complete automatic control is required or used, the automatic control sequences shall be initiated from an appropriately zoned automatic sprinkler system complying with Section 903.3.1.1 of the International Fire Code, from manual controls that are readily accessible to with access by the fire department, and any smoke detectors required by engineering analysis.

Reason: Coordination with P84-15 which replaced the term 'accessibility' with the clarification of providing access for repair or replacement or open to a location or fire department access. The term 'accessible' is defined in the IBC and relates to elements and facilities that serve or have special accommodations for persons with mobility impairments. The IPC and IMC use the term "Access (to)" or "Ready Access" – see below. This will clarify that the provisions are for access for repair, not accessibility for persons with disabilities.
[M]ACCESS (TO). That which enables a device, appliance or equipment to be reached by ready access or by a means that first requires the removal or movement of a panel, door or similar obstruction [see also "Ready access (to)"].
[M]READY ACCESS (TO). That which enables a device, appliance or equipment to be directly reached, without requiring the removal or movement of any panel, door or similar obstruction [see "Access (to)"].
This proposal is submitted by the ICC Fire Code Action Committee (FCAC). The FCAC was established by the ICC Board of Directors to pursue opportunities to improve and enhance assigned International Codes with regard to fire safety and hazardous materials in new and existing buildings and facilities and the protection of life and property in wildland urban interface areas. In 2014 and 2015 the Fire-CAC has held 5 open meetings. In addition, there were numerous conference calls, Regional Work Group and Task Group meetings for the current code development cycle, which included members of the committees as well as any interested parties, to discuss and debate the proposed changes. Related documentation and reports are posted on the FCAC website
at: FCAC
Cost Impact: Will not increase the cost of construction
This is a change in terminology for clarity and will have not technical changes to the codes.

Report of Committee Action Hearings

Committee Action:	Disapproved
Committee Reason: This proposal was preferred over F1-16 however there were concerns with how certain sections were addressing the replacement of the term accessible. In particular Sections 106.3 and 605.12 were noted. This proposal needs a more careful review of each section for specific wording to meet the intent.

Assembly Action:	None

ALTERNATIVE CONCEPTS

This appendix chapter provides consideration of the following alternatives: (1) exterior sprinkler systems, (2) alternative water supply systems for exposure protection, (3) Class A foam systems, (4) enhanced exterior fire protection, (5) sheltering in place, and (6) building location.

Exterior sprinkler systems. Currently, there is no nationally accepted standard for the design and installation of exterior fire sprinkler systems. Interior sprinkler systems are regulated by nationally recognized standards that have specific requirements. However, exterior sprinkler systems lack such uniformity. What is generally proposed is a type of sprinkler system, placed on the roofs or eaves of a building, whose primary purpose is to wet down the roof. These types of systems can be activated either manually or automatically. However, the contemporary thought on exterior sprinkler systems is that if the roof classification is of sufficient fire resistance, exterior sprinklers are of little or no value.

Another option and alternative with exterior sprinklers is to use them to improve the relative humidity and fuel moisture in the defensible space. In this case, the exterior sprinkler is not used to protect the structure as much as it attempts to alter the fuel situation. However, studies do not support the idea that merely spraying water into the air in the immediate vicinity of a rapidly advancing wildland-urban fire does much good. Clearly, irrigation systems that keep plants healthy and fire-resistive plants that resist convection and radiated heat can accomplish the same purpose.

Alternative water supply systems for exposure protection. Pools and spas are often offered as an alternative water source for fire departments. These water sources must be open for provided with access and reliable to be of any use by fire protection forces. Accessibility means that the fire department must be able to withdraw the water without having to go through extraordinary measures such as knocking down fences or having to set up drafting situations. Designs have been created to put liquid- or gas- fueled pumps or gravity valves on pools and spas to allow fire departments to access these water systems. A key vulnerability to the use of these alternative water systems is loss of electrical power. When the reliability of a water system depends on external power sources, it cannot be relied upon by fire fighters to be available in a worstcase scenario.

Class A foam systems. A new and emerging technology is the concept of Class A foam devices. These are devices that allow a homeowner to literally coat the exterior of their house with a thick layer of foam that prevents the penetration of embers and radiant heat to the structure. There is no nationally recognized standard for Class A foam technology; however, experiments in various wildland fire agencies seem to advocate foaming houses in advance of fire and flame fronts. To be accepted by the code official, the Class A foam system should pass rigorous scrutiny with regard to the manner and needs in which it is activated, the ways and means in which it is properly maintained, and a ways and means to test the system for its operational readiness during hiatus between emergencies.

Enhanced exterior fire protection. This alternative method would increase the degree of fire resistance on the exterior of a building. This is most often an alternative recommended as a retroactive application when individual properties cannot achieve adequate defensible space on the exterior of a building. Normally, fire resistance and building scenarios are concerned with containing a fire. Fire-resistance ratings within building design infers resistance to a fire for the specified time to compartmentalize the building's interior.
To improve fire resistance on the exterior of the structure, the primary emphasis is on preventing intrusion into the building.
This means protection of apertures and openings that may or may not be required to have any degree of fire resistance by accepted building codes. The option that is available here is for individuals to provide coverage in the form of shutters or closures to these areas, which, along with maintenance of perimeter-free combustibles, can often prevent intrusion.
There are obvious limitations to this alternative. First and foremost is the means of adequately evaluating the proposed fire resistance of any given assembly. Testing techniques to determine fire resistance for such objects as drywall and other forms of construction may not be applicable to exterior application. Nonetheless, code officials should determine the utility of a specific fire resistance proposal by extrapolating conservatively.

Shelter in place. Developments in the wildland-urban interface may be designed to allow occupants to "Shelter in Place." Use of this design alternative should include ignitionresistant construction, access, water supply, automatic sprinkler systems, provisions for and maintenance of defensible space, and a Fire Protection Plan.
A Fire Protection Plan describes ways to minimize the fire problems created by a specific project or development. The purpose for the Fire Protection Plan is to reduce the burden and impact of the project or development on the community's fire protection delivery system. The plan may utilize components of land use, building construction, vegetation management and other design techniques and technologies. It should include specific mitigation measures consistent with the unique problems resulting from the location, topography, geology, flammable vegetation and climate of the proposed site. The plan shall be consistent with this code, and approved by the fire code official. The cost of preparation and review is to be borne by the project or development proponent.

Building location. The location of a new building within lot lines should be considered as it relates to topography and fire behavior. Buildings located in natural chimneys, such as narrow canyons and saddles, are especially fire prone because winds are funneled into these areas and eddies are created. Buildings located on narrow ridges without setbacks may be subjected to increased flame and convective heat exposure from a fire advancing from below. Stone or masonry walls can act as heat shields and deflect the flames. Swimming pools and rated or noncombustible decks and patios can be used to create a setback, decreasing the exposure to the structure. Attic and under floor vents, picture windows and sliding glass doors should not face possible corridors due to the increased risk of flame or ember penetration.

2015 International Mechanical Code

513.12.4 Automatic control. Where complete automatic control is required or used, the automatic control sequences shall be initiated from an appropriately zoned automatic sprinkler system complying with Section 903.3.1.1 of the International Fire Code, from manual controls provided with ready access by the fire department, and any smoke detectors required by engineering analysis.

Commenter's Reason: This Public Comment responds to two issues raised and the CAH in Louisville.
First, when comparing the approach between F1 and F12, the approach taken by F12 was preferred at the CAH. So this Public Comment takes the approach of using the terms "access to" and ready access" when referring to the ability to use or access controls or components. The term 'accessible' is defined in the IBC and relates to elements and facilities that serve or have special accommodations for persons with mobility impairments. The terms "access to" and "ready access" are used in the IPC and IMC. Those definitions are proposed to be included here.

[M]ACCESS (TO). That which enables a device, appliance or equipment to be reached by ready access or by a means that first requires the removal or movement of a panel, door or similar obstruction [see also "Ready access (to)".

[M]READY ACCESS (TO). That which enables a device, appliance or equipment to be directly reached, without requiring the removal or movement of any panel, door or similar obstruction [see "Access (to)"].

Second, issues were raised regarding the actual wording proposed for the various sections throughout the codes. This Public Comment has reviewed each occurrence and made revisions as needed. The items shown in the Public Comment are revisions to the original proposal. Revisions from the original proposal which were found to be satisfactory are listed at the end of this reason statement.
Additionally, other code change proposals were heard at the Committee Action Hearing in Louisville that affected some of the sections contained in this Public Comment. The following sections contain modifications based on the CAH actions so that it is clear how the revised wording herein will fit with the other proposals.

Hydrogen-generating and refueling operations. Hydrogen-generating and refueling appliances shall be installed and located in accordance with their listing and the manufacturer's
instructions. Ventilation Exhaust ventilation shall be required in accordance with Section 703.1.1, 703.1.2 or 703.1.3 in public garages, private garages, repair garages, automotive motor fuel-dispensing facilities and parking garages that contain hydrogen-generating appliances or refueling systems in accordance with NFPA 2. For the purpose of this section, rooms or spaces that are not part of the living space of a dwelling unit and that communicate directly with a private garage through openings shall be considered to be part of the private garage.

Delete without substitution:

Natural ventilation. Indoor locations intended for hydrogen-generating or refueling operations shall be limited to a maximum floor area of 850 square feet (79 m2) and shall communicate with the outdoors in accordance with Sections 703.1.1.1 and 703.1.1.2. The maximum rated output capacity of hydrogen generating appliances shall not exceed 4 standard cubic feet per minute (0.00189 m3/s) of hydrogen for each 250 square feet (23.2 m2) of floor area in such spaces. The minimum cross-sectional dimension of air openings shall be 3 inches (76 mm). Where ducts are used, they shall be of the same cross-sectional area as the free area of the openings to which they connect. In such locations, equipment and appliances having an ignition source shall be located such that the source of ignition is not within 12 inches (305 mm) of the ceiling.

Two openings. Two permanent openings shall be provided within the garage. The upper opening shall be located entirely within 12 inches (305 mm) of the ceiling of the garage. The lower opening shall be located entirely within 12 inches (305 mm) of the floor of the garage. Both openings shall be provided in the same exterior wall.

If the design and free area are not known, it shall be assumed that wood louvers will have 25- percent free area and metal louvers and grilles will have 75-percent free area. Louvers and grilles shall be fixed in the open position.

Mechanical ventilation. Indoor locations intended for hydrogen-generating or refueling operations shall be ventilated in accordance with Section 502.16 of the International Mechanical Code. In such locations, equipment and appliances having an ignition source shall be located such that the source of ignition is below the mechanical ventilation outlet(s).

Specially engineered installations. As an alternative to the provisions of Sections 703.1.1 and 703.1.2, the necessary supply of air for ventilation and dilution of flammable gases shall be provided by an approved engineered system.

Reference standards type: This is an update to reference standard(s) already in the ICC Code Books
Add new standard(s) as follows:

IMC and IFGC
NFPA 2-2016 Hydrogen Technologies Code

Reason: This proposal is a comprehensive fix of the exhaust ventilation requirements for repair garages for hydrogen fueled vehicles and for exhaust ventilation requirements for the installation hydrogen-generating and refueling operations. The primary goal was consistency and correlation between the requirements found within the IFC, the IMC and the IFGC along with tighter correlation with the requirements of NFPA 2. (A special note: Currently the hydrogen exhaust requirements are blended with the requirements for other lighter than air fuels; this proposal separates those technical requirements with no technical change other than for hydrogen.)

Section 2311.7 of the fire code has been modified to separate the requirements for hydrogen fueled vehicles from other lighter than air fueled vehicles. A new Section 2311.7.1 has been added to direct the code user to NFPA 2 for hydrogen fueled vehicle repair garages.
All of the requirements for exhaust of repair garages for hydrogen fuel vehicles is covered in NFPA 2 where the IFC already directs the user for the overwhelming majority of the hydrogen as a fuel construction and operation requirements regulated by the fire code. In addition, the air exhaust rate is different in NFPA 2 for hydrogen and this proposal would point the user to the correct exhaust rate.
The exception language in 2311.7.2 (new numbering) was modified to match existing verbiage found in the IMC.
The word exhaust was added to or replaced references to ventilation throughout 2311.7 to correlate with the type of system being required in accordance with Chapter 5 Exhaust in the IMC.
The IMC correlating language found in Section 502.16 has been modified to match the scoping language found within the IFC as to types of fuels covered. The technical language has been aligned to pick up earlier changes to the IFC over several cycles as well as the new modifications proposed to separate out hydrogen fueled vehicles and point to NFPA 2 for those facilities.
Section 304.5 of the IMC, the correlating Section 703.1 of the IFGC address exhaust ventilation for occupancies with Hydrogen- generating and refueling appliances. The language has been modified to delete the three subsections and point the user to NFPA 2 where the requirements are covered. Eliminating the language provides clarification and eliminates a conflict within the mechanical code, Option 1 was natural ventilation with very specific requirements; Option 2 was mechanical exhaust which points to Section
502.16 of the mechanical code which again provided for a natural ventilation exception with no specific requirements. Option 3 was for a specialty engineered system with no parameters, as a result a designer would default to NFPA 2 for guidance.
By deleting the three options and pointing the user to NFPA 2 the correct requirements are provided including a natural ventilation option along with the other comprehensive portions of NFPA 2 that apply to this specialized type of installation.
The provisions NFPA 2 - related to the issues addressed in this proposal are found in Section 6.17 of NFPA 2-2016. A link to the NFPA website where free access is provided to the standard is as follows: NFPA 2

Cost Impact: Will not increase the cost of construction
This proposal will reduce the cost of installation by eliminating an internal conflict within the IMC, by correlating all of the ICC codes dealing with this topic, and by providing for tighter correlation with NFPA 2 which the I-Codes already refer to for these types of installations.
