WESTERN REGIONAL WORK GROUP ITEM 2B CODE CHANGE PROPOSAL Code: IBC 12/13 Code Sections/Tables/Figures Proposed for Revision: IBC Table 414.5.1 IFC Table 911.1 Revise IFC Table 911.1 as follows: TABLE 911.1 EXPLOSION CONTROL REQUIREMENTS EXPLOSION CONTROL METHODS MATERIAL CLASS Barricade construction Explosion (deflagration) venting or explosion (deflagration) prevention systems HAZARD CATEGORY Combustible dusts a Not Cryogenic fluids Flammable Not Explosives Flammable gas Flammable liquids Division 1.1 Division 1.2 Division 1.3 Division 1.4 Division 1.5 Division 1.6 Gaseous Liquefied IA b IB c Unclassified detonable I Not Not Not Not Not Not Not Not Not Not Organic peroxides Not Permitted Not Permitted Oxidizer liquids and solids 4 Not Permitted Pyrophoric Gases Not 4 Not Permitted Unstable (reactive) 3 Detonable Not Permitted 3 Nondetonable Not Water-reactive liquids and solids 3 Not 2 e Not SPECIAL USES Acetylene generator Not rooms Grain processing Not Liquefied petroleum gas Not distribution facilities Where explosion hazards exist d Detonation Deflagration Not Not Permitted a. Combustible dusts that are generated during manufacturing or processing. See definition of Combustible Dust in Chapter 22. b. Storage or use. c. In open use or dispensing. d. Rooms containing dispensing and use of hazardous materials when an explosive environment can occur because of the characteristics or nature of the hazardous materials or as a result of the dispensing or use process. e. A method of explosion control shall be provided when Class 2 water-reactive materials can form potentially explosive mixtures. Page 2 of 48

f. Explosion venting is not required for Group H-5 Fabrication Areas complying with Chapter 27 and the International Building Code. Also, revise IBC Table 414.5.1 as follows: [F] TABLE 414.5.1 EXPLOSION CONTROL REQUIREMENTS a,h MATERIAL CLASS Barricade construction EXPLOSION CONTROL METHODS Explosion (deflagration) venting or explosion (deflagration) prevention systems b HAZARD CATEGORY Combustible dusts c Not Cryogenic flammables Not Explosives Division 1.1 Division 1.2 Division 1.3 Division 1.4 Division 1.5 Division 1.6 Not Not Not Not Not Not Flammable gas Gaseous Not Liquefied Not Flammable liquid IA d Not IB e Not Organic peroxides U Not Permitted I Not Permitted Oxidizer liquids and solids 4 Not Permitted Pyrophoric gas Not Unstable (reactive) 4 3 Detonable 3 Nondetonable Not Not Permitted Not Permitted Water-reactive liquids and solids 3 2 g Not Not SPECIAL USES Acetylene generator room Not Grain processing Not Liquefied petroleum gasdistribution facilities Not Where explosion hazards Detonation Not Permitted exist f Deflagration Not a. See Section 414.1.3. b. See the International Fire Code. c. As generated during manufacturing or processing. d. Storage or use. e. In open use or dispensing. f. Rooms containing dispensing and use of hazardous materials when an explosive environment can occur because of the characteristics or nature of the hazardous materials or as a result of the dispensing or use process. g. A method of explosion control shall be provided when Class 2 water-reactive materials can form potentially explosive mixtures. h. Explosion venting is not required for Group H-5 Fabrication Areas complying with IBC 415.10.1 and the International Fire Code. REASON: This proposal is intended to reduce confusion in the application of explosion venting requirements to Group H-5 Occupancies. Currently, IBC and IFC require explosion Page 3 of 48

venting where MAQs are exceeded per IFC Table 5003.1.1 and IBC Table 307.1. However, fabrication areas of H-5 Occupancies are specifically allowed to exceed these quantities in accordance with IBC 415.10.1.1.1 and IFC 2704.2.2.1 due to the strict controls prescribed in for those fabrication areas. This proposal would clarify that explosion venting is not required in the fabrication areas of H-5 Occupancies. HPM storage rooms and gas rooms are also allowed to exceed the limits of Tables 2704.2.2.1 and IBC 415.10.1.1.1.Explosion venting would still potentially be required in the HPM storage rooms and gas rooms. This is currently clarified in IBC 415.10.5.5. This proposal is consistent with current construction and interpretation of explosion venting requirements, as Group H-5 fabrication areas are generally constructed without explosion venting. This proposal simply provides clarification on how the Group H5 requirements correlate with MAQs and explosion venting requirements found elsewhere in code. Page 4 of 48

WESTERN REGIONAL WORK GROUP ITEM 9 CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections Proposed for Revision: IFC 914.3 (new) IBC 403.4.4 (new), 405.6 (new) Proponent: Western RWG Add Section 914.3 to the IFC as follows: 914.3 (IBC [F] 914.3) Firefighter breathing air replenishment systems. A firefighter breathing air replenishment system shall be installed in the following buildings and structures: Exception: When approved by the Fire Chief, an alternative system or method to provide breathing air replenishment to firefighters under emergency conditions is permitted. Documentation describing the approved alternative system or method shall be maintained by the fire code official and provided to the owner. 1. High-rise buildings. 2. Underground buildings regulated by Section 405 of the International Building Code. 3. Basements consisting of three or more stories below grade. 4. Buildings with an aggregate floor area greater than 200,000 ft 2 and where any portion of the building s interior area is more than 500 feet (152 m) of travel, vertically and horizontally, from the nearest point of fire department vehicle access. 5. Underground transportation or pedestrian tunnels where any portion of the tunnel is more than 500 feet (152 m) of travel, vertically and horizontally, from the nearest point of fire department vehicle access. Add Section 403.4.4 to the IBC as follows: [F] 403.4.4 Firefighter breathing air replenishment system. A firefighter breathing air replenishment system shall be shall be provided in accordance with Section 914.3. (renumber subsequent sections ) Add Section 405.7 to the IBC as follows: [F] 405.6 Firefighter breathing air replenishment system. A firefighter breathing air replenishment system shall be shall be provided in accordance with Section 914.3. (renumber subsequent sections ) REASON: This proposal will provide a requirement to provide a method to refill firefighter breathing air bottles during an emergency. This requirement is only applicable in specific large Page 5 of 48

buildings or buildings which present an extreme difficulty in getting a fresh air supply to the firefighters fighting the fire. This proposal does not specify the method in which the breathing air is supplied. The decision as to how this is accomplished can vary from fire department to fire department. It is typically dependent on the fire department vehicles and capabilities of the fire department. Page 6 of 48

WESTERN REGIONAL WORK GROUP ITEM 23 CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections Proposed for Revision: IFC 605.11.5, 605.11.5 (new), 605.11.5.1 (new) Revise IFC Section 605.11.5 as follows: 605.11 Solar photovoltaic power systems. Solar photovoltaic power systems shall be installed in accordance with Sections 605.11.1 through 605.11.4, the International Building Code and NFPA 70. Exception: Detached, nonhabitable Group U structures including, but not limited to, parking shade structures, carports, solar trellises and similar structures shall not be subject to the requirements of Sections 605.11.1 through 605.11.4. Add Section 605.11.5 to the IFC as follows: 605.11.5 Group U structures. Solar photovoltaic power systems on detached, nonhabitable Group U structures including, but not limited to, parking shade structures, carports, solar trellises and similar structures shall comply with this section. 605.11.5.1 Main service disconnect. A main service disconnect shall be provided on each structure. A marking shall be provided adjacent to the main service disconnect in a location clearly visible from the location where the disconnect is operated that complies with 605.11.1.1 and 605.11.1.2. REASON: As written the code exempts photovoltaic systems located on detached canopies and similar structures from complying with the IBC, NFPA 70 and all requirements in section 605.11, while section 105 requires a permit to be issued for these systems. This proposal clarifies that the installation must comply with the IBC for structural and other provisions, and NFPA 70 for electrical provisions. It also requires that access be provided to the structure that is consistent with 605.11.3.3.1. It also requires each structure to be provide with a main service disconnect that is marked in accordance with section 605.11.1. Page 7 of 48

WESTERN REGIONAL WORK GROUP ITEM 41 CODE CHANGE PROPOSAL Code: IBC/IFC 12/13 Code Sections Proposed for Revision: IBC 3103.1, 3106.5 (new), IFC 3103.9 Revise IBC Section 3103.1 as follows: 3103.1 General. The provisions of Sections 3103.1 through 3103.4 shall apply to structures erected for a period of less than 180 days. Structures erected for a longer period of time shall comply with the applicable sections of this code. Tents and other membrane structures erected for a period of less than 180 days shall comply with the International Fire CodeSection 3102. Those erected for a longer period of time shall comply with applicable sections of this code. Add IBC Section 3103.5 as follows: 3103.5 Structural Design. Temporary structures shall comply with Chapter 16. Revise IFC Section 3103.9 as follows: 3103.9 Anchorage required. Tents or membrane structures and their appurtenances shall be adequately roped, braced and anchored to withstand the elements of weather and prevent against collapsing. Documentation of structural stability shall be furnished to the fire code official on request. Tents or membrane structures shall comply with the IBC Chapter 16 where any of the following conditions occur: 1. The tent or membrane structure has an occupant load exceeding 100. 2. The tent or membrane structure is a Group A, E, I or R occupancy. 3. The tent or membrane structure exceeds one story in height. REASON: Temporary structures continue to grow in size and occurrence. These structures can be seen at concerts, outdoor functions, fairs, etc. Even though the provision of temporary limits the usability of these structures to less than 180 days, their structural design still needs to be reviewed. Many of these temporary structures are multiple floors, and over 30 feet in height. As the height increases, the impact of collapse increases and typically these structures are surrounded by hundreds of people. The IBC currently regulates Temporary Structures in Section 3103. Section 3103.5 is added to include a specific reference to the structural requirements in Chapter 16. Page 8 of 48

WESTERN REGIONAL WORK GROUP ITEM 68 CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections Proposed for Revision: IFC 907.6.3, 907.6.3.1, 907.6.3.2 Proponent: Western RWG Revise IFC Section 907.6.3 as follows: 907.6.3 (IBC [F] 907.6.3) Zones. Each floor shall be zoned separately and a zone shall not exceed 22,500 square feet (2090 m 2 ). The length of any zone shall not exceed 300 feet (91 440 mm) in any direction. Exception: Automatic sprinkler system zones shall not exceed the area permitted by NFPA 13. 907.6.3.1 (IBC [F] 907.6.3.1) Zoning indicator panel. A zoning indicator panel and the associated controls shall be provided in an approved location. The visual zone indication shall lock in until the system is reset and shall not be canceled by the operation of an audible alarm-silencing switch. 907.6.3.2 (IBC [F] 907.6.3.2) High-rise buildings. In high-rise buildings, a separate zone by floor shall be provided for each of the following types of alarm-initiating devices where provided: 1. Smoke detectors. 2. Sprinkler water-flow devices. 3. Manual fire alarm boxes. 4. Other approved types of automatic fire detection devices or suppression systems. 907.6.3 (IBC [F] 907.6.3) Initiating device identification. The fire alarm system shall include a means to identify the specific initiating device address, location, device type, floor level (if applicable) and status including indication of normal, alarm, trouble and supervisory status, as appropriate. 907.6.3.1 (IBC [F] 907.6.3.1) Annunciation. The initiating device status shall be displayed at an approved on-site location. REASON: This proposal is intended to help the code official identify the status of individual initiating devices, which is readily achievable using existing fire alarm control unit technology. This will help identify problematic initiating devices and thus reduce nuisance alarms. It also will allow the fire department to more effectively respond to actual fires in premises. It also eliminates the requirements for providing zone indication of system status. initiating device status shall be displayed at an approved location at the premise, such as the fire alarm control unit, fire command center and/or zone annunciator panel. Cost Impact: The code change proposal will not increase the cost of construction. Page 9 of 48

WESTERN REGIONAL WORK GROUP ITEM 69A CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections Proposed for Revision: IFC 907.4.4 (new) Proponent: Western RWG Add new Section 907.4.4 to the IFC as follows: 907.4.4 (IBC [F] 907.4.4) Automatic Fire Sprinkler Waterflow Alarm. Where fire sprinkler waterflow alarm initiating devices are installed, the activation of the device shall occur no sooner than 30 seconds and no longer than 90 seconds after sprinkler water flow occurs that is equal to or greater than the flow from a single fire sprinkler with the smallest orifice size installed in the system. Revise IFC Section 907.4 as follows: 907.4 (IBC [F] 907.4) Initiating devices. Where manual or automatic alarm initiation is required as part of a fire alarm system, the initiating devices shall be installed in accordance with Sections 907.4.1 through 907.4.3.1 907.5. Reason: This proposal is intended to help reduce nuisance alarms. The intent is to establish a minimum time setting on waterflow devices, whereby currently NFPA 72 only has a maximum. As water distribution systems have become more dynamic over time, water systems tend to fluctuate considerably and result in more unintentional activation of water flow devices. Page 10 of 48

WESTERN REGIONAL WORK GROUP ITEM 69B CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections Proposed for Revision: IFC 907.6.6 (new), 907.6 Proponent: Western RWG Add new Section 907.6.6 to the IFC as follows: 907.6.6 (IBC [F] 907.6.6) Alarm Signal Verification. Where required by the Fire Chief, supervising station personnel shall attempt to verify an alarm signal prior to reporting them to the emergency response communications center in accordance with the following: (1) When the supervising station receives an alarm signal, the supervising station attempt to verify that the alarm signal necessitates an emergency response. (2) The supervising station verification process shall not exceed 90 seconds from the time the alarm signal is received until the time that retransmission of a verified alarm signal to the emergency response communications center is initiated. (3) Verified alarm signals shall immediately be retransmitted to the emergency response communications center and include information that the signal was verified by the protected premises as an emergency. (4) When alarm signals cannot be verified, the supervising station shall immediately retransmit the alarm to the emergency response communications center. (5) Alarm signals not verified as needing emergency response shall not be retransmitted to the emergency response communications center. (6) Alarm signals not transmitted to the emergency response communications center shall be reported to the fire department in a manner and a frequency specified by the fire department. Revise IFC Section 907.6 as follows: 907.6 (IBC [F] 907.6) Installation. A fire alarm system shall be installed in accordance with Sections 907.6.1 through 907.6.5.2 907.6.6 and NFPA 72. REASON: The intent is to allow fire departments to require verification on both commercial and residential alarm signals in order to assist in effective dispatching of resources and/or reducing nuisance alarms. Currently NFPA 72 allows verification on residential systems (but gives choice of using it to the monitoring company). This would give discretion to the AHJ, and expand use to include commercial alarms which accounts for the majority of false alarms in the U.S. Many departments have dramatically different response protocols for automatic alarm signals than for working fires, with many responding with single units or non-emergency priority compared to a full first alarm assignment for working fires or smoke showing. This would allow a brief period of time in which the supervising station would attempt to gather more information which could be critical in dispatching the correct resources and Page 11 of 48

significantly bolster response size and speed. Additionally, by checking for unintentional activations (as is commonly done in residential applications) nuisance alarms can be reduced. Page 12 of 48

WESTERN REGIONAL WORK GROUP ITEM 70 CODE CHANGE PROPOSAL Code: IFC/IRC 12/13 Code Sections Proposed for Revision: IFC 907.2.11.3 (new), 907.2.11.4 (new), IRC R314.3.1 (new), R314.3.2 (new) 1. Add Sections 907.2.11.3 and 907.2.11.4 to the IFC and renumber the remaining sections as follows: 907.2.11.3 Installation near cooking appliances. Smoke alarms shall not be installed within a 20 foot (6.1 m) horizontal distance from a stationary or fixed cooking appliance unless this would prevent placement of a smoke alarm required by other sections of the code. Exception: 1. Ionization smoke alarms with an alarm-silencing switch shall be allowed to be installed 10 feet (3 m) or more from a stationary or fixed cooking appliance. 2. Photoelectric smoke alarms shall be allowed to be installed 6 feet (1.8 m) or more from a stationary or fixed cooking appliance. 907.2.11.4 Installation near bathrooms. Smoke alarms shall not be installed within a 3 foot (0.91 m) horizontal distance from the door of a bathroom that contains a bathtub or shower unless this would prevent placement of a smoke alarm required by other sections of the code. 907.2.11.3 907.2.11.4 Interconnection. (text remains unchanged ) 2. Add Section R314.3.1 and R314.3.2 to the IRC and renumber the remaining sections as follows: R314.3.1 Installation near cooking appliances. Smoke alarms shall not be installed within a 20 foot (6.1 m) horizontal distance from a stationary or fixed cooking appliance unless this would prevent placement of a smoke alarm required by other sections of the code. Exception: 1. Ionization smoke alarms with an alarm-silencing switch shall be allowed to be installed 10 feet (3 m) or more from a stationary or fixed cooking appliance. 2. Photoelectric smoke alarms shall be allowed to be installed 6 feet (1.8 m) or more from a stationary or fixed cooking appliance. R314.3.2 Installation near bathrooms. Smoke alarms shall not be installed within a 3 foot (0.91 m) horizontal distance from the door of a bathroom that contains a bathtub or shower unless this would prevent placement of a smoke alarm required by other sections of the code. R314.3.1 R314.3.3 Alterations, repairs and additions. (text remains unchanged ) REASON: Page 13 of 48

This proposal is intended to reduce nuisance alarms attributed to locating smoke alarms in close proximity to cooking appliances and bathrooms in which steam is produced. The proposed provisions are based on the findings documented n the Task Group Report - Minimum Performance Requirements for Smoke Alarm Detection Technology - February 22, 2008, and are consistent with similar requirements included in the 2010 edition of NFPA 72. Section 907.2.11 already requires smoke alarms to be installed in accordance with NFPA 72, which theoretically describes where alarms should and should not be installed. As a convenience to the code, requirements on where smoke alarms should not be installed in proximity to cooking appliance and steam producing bathrooms will be included in this section. Page 14 of 48

WESTERN REGIONAL WORK GROUP ITEM 71 CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections Proposed for Revision: IFC 907.2.11, 907.8.3 (new) Revise IFC section 907.2.11 as follows: 907.2.11 Single- and multiple-station smoke alarms. Listed single- and multiplestation smoke alarms complying with UL 217 shall be installed and maintained in accordance with Sections 907.2.11.1 through 907.2.11.4, Section 907.8.3 and NFPA 72. Add a new IFC section 907.8.3 and renumber the remaining sections: 907.8.3 Smoke alarms. Smoke alarms shall be tested and maintained in accordance with the manufacturer s instructions. Smoke alarms that become inoperable or fail to respond to tests shall be replaced. Smoke alarms installed in one- and two-family dwellings shall be replaced after 10 years from the date of manufacture marked on the unit, or after 10 years of service if the date of manufacture is not visible. 907.8.3 907.8.4 Smoke detector sensitivity. (Text remains unchanged ) REASON: This proposal clarifies the requirements in Section 901.4 for testing and maintaining smoke alarms, and specifies when the devices need to be replaced. The proposed requirements are consistent with NFPA 72 provisions. In particular NFPA 72 requires smoke alarms installed in one- and two-family dwellings to not remain in service longer than 10 years from the date of manufacture, and UL 217 requires the date of manufacture to be marked on the smoke alarms. It is recognized that it may not always be practical for the code official to enforce the requirements for testing, maintenance and replacement of smoke alarms in residential dwelling units. However realtors and landlords often have checklists that verify that these dwellings comply with codes and other requirements, and they may be in a position to verify compliance with the proposed provisions when the units are sold or leased.

R315.2.2 Combination alarms. Combination carbon monoxide/smoke alarms shall be permitted to be used to comply with Section R314 and R315 requirements provided the units are listed in accordance with both UL 217 and UL 2034 requirements, and installed per the manufacturer s instructions and in accordance with Section R314 and R315 requirements. R315.3 R315.2 Carbon monoxide detection systems. Carbon monoxide detection systems that include carbon monoxide detectors and audible notification appliances, Page 16 of 48

installed and maintained in accordance with this section for carbon monoxide alarms and NFPA 720, shall be permitted. The carbon monoxide detectors shall be listed as complying with UL 2075. Where a household carbon monoxide detection system is installed, it shall become a permanent fixture of the occupancy, owned by the homeowner and shall be monitored by an approved supervising station. Exception: Where carbon monoxide alarms are installed meeting the requirements of Section R315.1, compliance with Section 315.2315.3 is not required. R315.4 R315.3 Where required in existing dwellings. Where work requiring a permit occurs in existing dwellings that have attached garages or in existing dwellings within which fuel fired appliances exist, carbon monoxide alarms shall be provided in accordance with Section R315.1. Revise IFC Section 908.7 as follows: 908.7 Carbon monoxide alarms. Group I or R occupancies located in a building containing a fuel-burning appliance or in a building which has an attached garage shall be equipped with single-station carbon monoxide alarms. Carbon monoxide alarms shall be installed in the following locations: 1. Outside of each separate sleeping area in the immediate vicinity of the sleeping units or bedrooms. 2. In sleeping units and bedrooms that contain a fuel-burning appliance. The carbon monoxide alarms shall be listed as complying with UL 2034 and be installed and maintained in accordance with NFPA 720 and the manufacturer s instructions. An open parking garage, as defined in Chapter 2 of the International Building Code, or an enclosed parking garage ventilated in accordance with Section 404 of the International Mechanical Code shall not be considered an attached garage. Exception: Sleeping units or dwelling units which do not themselves contain a fuel-burning appliance or have an attached garage, but which are located in a building with a fuel-burning appliance or an attached garage, need not be equipped with single-station carbon monoxide alarms provided that: 1. The sleeping unit or dwelling unit is located more than one story above or below any story which contains a fuel-burning appliance or an attached garage; 2. 1. The sleeping unit or dwelling unit is not connected by duct work or ventilation shafts to any room containing a fuel-burning appliance or to an attached garage; and 2. A carbon monoxide alarm is provided over the fuel-burning appliance that will activate an audible alarm in a constantly attended receiving station or audible to the building occupants. 3. The building is equipped with a common area carbon monoxide alarm system. A carbon monoxide alarm is provided in the common area between the attached garage and the sleeping units/dwelling units that will activate an audible alarm in a constantly attended receiving station or audible to the building occupants. Page 17 of 48

908.7.1 Carbon monoxide alarm shall comply with Section 908.7.2. Combination carbon monoxide alarms shall comply with Section 908.7.2.2. Carbon monoxide detection systems shall comply with Section 908.7.3 908.7.2 Carbon monoxide alarms. Carbon monoxide alarms shall be installed and maintained in accordance with NFPA 720, and shall be listed in accordance with UL 2034. 908.7.2.1 Power source. Carbon monoxide alarms shall receive their primary power from the building wiring when such wiring is served from a commercial source, and when primary power is interrupted, shall receive power from a battery. Wiring shall be permanent and without a disconnecting switch other than those required for overcurrent protection. Exceptions: 1. Carbon monoxide alarms shall be permitted to be battery operated when installed in buildings without commercial power. 2. When approved by the code official, units that connect to ac receptacles via power supply cords shall be allowed provided that an approved restraining means is provided to secure the cord to the receptacle. 908.7.2.2 Combination alarms. Combination carbon monoxide/smoke alarms shall be permitted to be used provided the units are listed in accordance with both UL 217 and UL 2034 requirements, and installed in accordance with Sections 908.7.2 and 907.2.11, as applicable. 908.7.3 908.7.1 Carbon monoxide detection systems. Carbon monoxide detection systems, which include carbon monoxide detectors and audible notification appliances, installed and maintained in accordance with this section Section 908.7.2 for carbon monoxide alarms and NFPA 720 shall be permitted. The carbon monoxide detectors shall be listed as complying with UL 2075. IFC Requirements for Existing Buildings Revise IFC Section 1103.9 as follow: 1103.9 Carbon monoxide alarms. Existing Group I or R occupancies located in a building containing a fuel-burning appliance or a building which has an attached garage shall be equipped with single-station carbon monoxide alarms. The carbon monoxide alarms shall be listed as complying with UL 2034, and be installed and maintained in accordance with NFPA 720 and the manufacturer s instructions. An open parking garage, as defined in the International Building Code, or an enclosed parking garage ventilated in accordance with Section 404 of the International Mechanical Code shall not be deemed to be an attached garage. Exception: Sleeping units or dwelling units which do not themselves contain a fuel-burning appliance or have an attached garage, but which are located in a building with a fuel-burning appliance or an attached garage, need not be equipped with single-station carbon monoxide alarms provided that: 1. The sleeping unit or dwelling unit is located more than one story above or below any story that contains a fuel-burning appliance or an attached garage; Page 18 of 48

21. The sleeping unit or dwelling unit is not connected by duct work or ventilation shafts to any room containing a fuel-burning appliance or to an attached garage; and 2. A carbon monoxide alarm is provided in common areas on each floor of the building that contains sleeping units. 3. The building is provided with a common area carbon monoxide alarm system. REASON: This proposal clarifies requirements for carbon monoxide detection devices in both the IRC and the IFC, as follows. 1. IRC Section R315 currently intermixes requirements for CO alarms and CO detection systems in a way that might be confusing. The proposal consolidates CO alarm requirements in Section R315.2 and the CO detection system requirements in R315.3. Section R315.1still specifies where CO detection devices are needed, with no changes. 2. New IRC Section R315.2.1 includes new requirements for CO alarm power supplies that are consistent with R314 smoke alarm power supply requirements. It also allows cord and plug connected units to be provided, as allowed in NFPA 720, when approved by the code official. 3. New IRC Section R315.2.2 addresses combination CO/smoke alarms, which are Listed and readily available. 4. Similar revisions and reformatting changes have been proposed for the IFC. 5. IFC 908.7 included exceptions on where CO detection devices were not required, but did not describe where they were required. Accordingly, where required requirements are clarified. 6. The requirements for providing carbon monoxide alarms in Group I occupancies is being eliminated due to the presence of trained staff at these facilities. Page 19 of 48

WESTERN REGIONAL WORK GROUP ITEM 80 CODE CHANGE PROPOSAL Code: IFC 12/13 Code Sections/Tables/Figures Proposed for Revision: IFC 319 (new) Add new Section 319 to the IFC as follows: SECTION 319 EXHIBITIONS AND TRADE SHOWS 319.1 General. Indoor exhibitions and trade shows are addressed in this section.

REASON: This proposal simplifies the list of criteria for security gates. The requirements in Item 6 can easily be covered in the revision to Item 7. Item 6 currently lists specific methods of locking access gates. Item 6 then becomes unnecessary so it is proposed to be deleted. The reality is that there are many other methods available which can be utilized to lock a gate. Whatever the method of locking, the need is to have the method approved. This will now be covered in the new Item 6. Page 24 of 48
