Basement. A story of a building or a structure having one-half or more of its height below ground level on any side and to which access for emergency incident mitigation purposes is unduly restricted. ( 30B, 007) This definition is the preferred definition from the NFPA Glossary of Terms. Changing the secondary definition to the preferred definition complies with the Glossary of Terms Project. Replace the current definition of "basement" in 3.3. with the following: "3.3. Basement. For the purposes of this code, a story of a building or structure having one-half or more of its height below ground level and to which access for fire-fighting purposes is restricted. [30:008]" The word "unduly" in the preferred definition is nebulous and, within the context of, the definition extracted from NFPA 30 is more accurate. The key issue relative to is safe access to and evacuation from the basement area by emergency responders during an emergency. 3

5 30A-8 Log #CP7 Add an extract identifier at the end of the definition to read: "[30, 008]" This definition is extracted from NFPA 30 and should be identified as such. 30A-9 Log #CP9 Revise to read: "3.3.9* Liquid. Any material that () has a fluidity greater than that of 300 penetration asphalt when tested in accordance with ASTM D 5, Standard Method of Test for Penetration of Bituminous Materials or () is a viscous substance for which a specific melting point cannot be determined but that is determined to be a liquid in accordance with ASTM D 4359, Standard Test for Determining Whether a Material is a Liquid or a Solid.

Any liquid that has a closed-cup flash point at or above 00 F (37.8 C), as determined by the test procedures and apparatus set forth in Section of NFPA 30, Flammable and Combustible Liquids Code. Combustible liquids shall be classified in accordance with [30, 008] (No change to Annex text.) Combustible liquids shall be classified in accordance with the following: () Class II Liquid Any liquid that has a flash point at or above 00 F (37.8 C) and below 40 F (60 C) () Class III Liquid Any liquid that has a flash point at or above 40 F (60 C) (a) Class IIIA Liquid Any liquid that has a flash point at or above 40 F (60 C), but below 00 F (93 C) (b) Class IIIB Liquid Any liquid that has a flash point at or above 00 F (93 C).

Any liquid that has a closed-cup flash point below 00 F (37.8 C), as determined by the test procedures and apparatus set forth in Section of NFPA 30, Flammable and Combustible Liquids Code, and a Reid vapor pressure that does not exceed an absolute pressure of 40 psi (76 kpa) at 00 F (37.8 C), as determined by ASTM D 33, Standard Method of Test for Vapor Pressure of Petroleum Products (Reid Method) [30, 008] Flammable liquids shall be classified in accordance with [30, 008] A Flammable Liquid. For the purposes of this code, a material with a Reid Vapor Pressure greater than 068 mm Hg absolute (40 psia) is considered to be a gas and is, therefore, not within the scope of. See NFPA 58, Liquefied Petroleum Gas Code. See Annex B for information about typical liquids found at motor fuel dispensing facilities Flammable liquids shall be classified in accordance with the following: () Class IA Liquid Any liquid that has a flash point below 73 F (.8 C) and a boiling point below 00 F (37.8 C) () Class IB Liquid Any liquid that has a flash point below 73 F (.8 C) and a boiling point at or above 00 F (37.8 C) (3) Class IC Liquid Any liquid that has a flash point at or above 73 F (.8 C), but below 00 F (37.8 C).

Flammable liquids are classified according to Section.7. This amendment essentially relocates to Chapter 3 definitions that appear in Section.7 in the current edition of. Definitions belong in Chapter 3, not the administrative chapter of the code. The text has been further amended by extracting the appropriate liquid classification information from NFPA 30. 4

6 30A-0 Log #CP0 Add an extract identifier to the end of this definition to read: "[30, 008]" This definition is extracted from NFPA 30 and should be identified as such. 30A- Log #CP Delete this definition. The term "portable tank" is not used in the. 30A- Log #CP Change the following references to NFPA 30, as indicated: In 4..4, replace " " with ".3.". In 4.3., replace "Chapters through 3 and 7" with "Chapters and 3". In 4.3., replace "Chapters through 3 and 7" with "Chapters and ". In , replace "..7." with ".7. and Section.". In , replace "5.3" with "7.8.". In , replace ".3.4" with ".3.4". In , replace "4.3..." with "Section.4". In 4.3.4(), replace "[30,.0.]" with "[30, 008]". Correction of errors in referencing text from NFPA A-3 Log #CP0 Revise to read: "Tanks storing liquid motor fuels Class I and Class II liquids at an individual site shall be limited to a maximum individual capacity of 45,400 L (,000 gal) and aggregate capacity of 8,700 L (48,000 gal) unless such tanks are installed in vaults complying with 4.3.3, in which case the maximum individual capacity shall be permitted to be 57,000 L (5,000 gal). This amendment allows the use of alternative liquid fuels that are Class III liquids. 5

7 30A-4 Log #CP Revise to read: "The provisions of this subsection shall not prohibit the dispensing of liquid motor fuels Class I and Class II liquids in the open from..... " (The remainder of the paragraph is unchanged.) This amendment allows the use of alternative liquid fuels that are Class III liquids. 30A-5 Log #CP3 Revise to read: "Vaults Each vault shall be provided with an approved vapor and liquid detection system that is and equipped with on-site audible and visual warning devices with battery back-up. [30, 008:5.5.] This requirement was taken from NFPA 30, but reworded slightly. It is more appropriate to extract the text verbatim. 30A-6 Log #3 Alex Ralston, Petcon, Inc. Revise text as follows: All openings shall be located above the maximum liquid level (for horizontal tanks). Large vertical tanks located at service stations and fleet fueling sites are 0-30 ft. high. It is not practical to fill these tanks from the top or to have manways located on the roof. These large tanks are typically filled at the bottom of the tank and the manway is located near the ground for access to the floor of the tank. Also, define openings. Do you mean any fitting or are you referring to manways? This proposal is not sufficiently specific to identify which vertical tanks are to be exempted: those that are located in a diked area or those that are the secondary containment-type and are NOT situated in a diked area. Other issues include the number and types of connections and tank capacity. The submitter is encouraged to submit an appropriate comment during the public review period. 30A-7 Log #CP4 Change title of section to read: "Corrosion Protection Control". Revise the annex by adding the following sentence at the end: " Other means of internal corrosion protection include protective coatings and linings and cathodic protection." The changes proposed correlate with NFPA 30 from on which the requirement is based. 6

8 30A-8 Log #CP5 Revise to read: "5.6. Vent piping shall meet the requirements of Section , 7.8.., , and of NFPA 30, Flammable and Combustible Liquids Code. [30, 008:5.5.]" It is more appropriate to reference the entirety of Section 7.8 to ensure that none of the vent piping provisions in NFPA 30 are overlooked or ignored. 30A-9 Log #CP Add a new 6..3 to read: "6..3 Fuel-dispensing systems, including dispensers, hoses, nozzles, breakaway fittings, swivels, flexible connectors, dispenser emergency shutoff valves, vapor recovery systems and pumps that are used for alcohol blended motor fuels shall be listed or approved for the specific purpose." This language is necessary to address existing equipment being used in more than 00 existing motor fuel dispensing facilities that dispense E85 fuel (85 percent ethanol / 5 percent gasoline). This amendment also anticipates the Environmental Protection Agency decision now pending to approve the use of alcohol-blended fuels with ethanol concentrations above 0 percent but below 85 percent. 7

9 30A-0 Log #5 Eddie Phillips, Southern Regional Fire Code Development Committee Add new sections and renumber the remaining sections as follows:. Flammable and combustible liquid fuel dispensing equipment, leak detection equipment and secondary containment equipment shall be inspected as required by the AHJ to verify that it is in proper working order and is not subject to leakage or spills. A Qualified Person shall inspect the fuel-dispensing equipment that is located outside the cabinet of the dispenser unit. All the hanging hardware and the exterior of the dispenser shall be included in this route inspection to include the nozzle, hose, breakaway valve, swivel, impact protection, and required signage. The frequency of the inspection shall be determined by the AHJ and shall be documented to show needed maintenance and corrective action. All inspection reports shall be available for review by the code official upon request. (add PEI/RP Inspection Forms from appendix B- through B-3.) A Qualified Person shall inspect the fuel-dispensing equipment that is located inside the dispenser cabinet. The interior of the fuel-dispenser cabinet shall be inspected for signs of leaks, damage, corrosion, or weathering. The frequency of the inspection shall be determined by the AHJ and shall be documented to show needed maintenance and corrective action. All inspection reports shall be available for review by the AHJ upon request. (add PEI/RP Inspection Forms from appendix B-4 through B-5.) The AHJ is authorized to require damaged or unsafe dispensing equipment, leak detection, or secondary containment equipment and to be repaired or serviced in an approved manner. This includes equipment that shows signs of physical damage, internal and external corrosion, brittleness, aging, undo wear and tear, or other damage. When maintenance to dispensing devices is necessary and such maintenance is capable of causing accidental release or ignition of liquid, the following precautions shall be taken before such maintenance is begun: () Only persons knowledgeable in performing the required maintenance shall perform the work. () All electrical power to the dispensing devices, to the pump serving the dispensing devices, and to all associated control circuits shall be shut off at the main electrical disconnect panel. (3) The emergency shutoff valve at the dispenser, if installed, shall be closed. (4) All vehicular traffic and unauthorized persons shall be prevented from coming within 6 m (0 ft) of the dispensing device. This proposal provides basic provisions for the inspection, repair, and servicing of flammable and combustible liquid dispensing system equipment, which are not currently covered in. The need for these requirements has been brought to light due to concerns with potential leakage of E85 dispensing system components, and with reported leakages from other fuel containment system components. Proposed new regulations to part authorizes the fire official to require inspection of equipment on a periodic basis, and identifies that the inspection is to verify the equipment is in proper working order and isn t leaking. The frequency and nature of the inspections is up to the discretion of the fire code official. A Qualified Person shall conduct all inspections. The PEI defines who a qualified person is, but in some locations, state and local laws and rules will define who a qualified person is under the adoption regulation. This is designed to be similar to NFPA 58 for LP gas regulations. This person is someone that has been trained to identify hazardous condition and problems, but may not be trained to the level needed to conduct maintenance as required in The annex notes provide copies of the PEI checklists that can be used as a guide for local official to monitor the inspection of the equipment to a nationally recognized association. If needed the checklists can be modified to stay within the scope of and referenced standards. Additionally, this proposed regulation authorizes the fire code official to require damaged or leaking equipment to be serviced or repaired in an approved manner. Together the new proposed provisions work well with the other requirements under maintenance. In a perfect world, having a comprehensive set of requirements covering the inspection and testing of motor vehicle fuel containment and dispensing system components, similar to requirements in place for fire alarm systems, would be the best way to cover this issue. However, since these requirements are not in place, these provisions provide some 8

10 basic requirements that may eventually lead to a more complete treatment of this area. Add a new to incorporate the existing text to read as follows: "6.3.6 Inspections. Dispensing equipment shall be periodically inspected by a person who is knowledgeable in the operation of the equipment to verify that it is in proper working order and is not leaking Exterior Inspection* A visual inspection of the fuel-dispenser and its associated hanging hardware shall be conducted. Hanging hardware shall include the following dispenser components that may be present: the hose nozzle valve, hose, breakaway valve, and hose swivel. Inspections shall be conducted at least weekly and shall be documented. Documentation shall be available for review by the authority having jurisdiction upon request. A Useful forms for documentation are presented in PEI/RP500-05, Recommended Practices for Inspection and Maintenance of Motor Fuel Dispensing Equipment and are available at Internal Dispenser Cabinet Inspection*. An inspection of the fuel-dispensing equipment that is located inside the dispenser cabinet shall be conducted. The interior of the fuel-dispenser cabinet shall be inspected for signs of leaks, damage, corrosion, or weathering, with particular attention to the sump area and joints and castings of fluid handling components. The inspection shall be conducted at least monthly and shall be documented. Documentation shall be available for review by the authority having jurisdiction upon request. A See A Maintenance. When maintenance to dispensing devices is necessary and such maintenance is capable of causing accidental release or ignition of liquid, the following precautions shall be taken before such maintenance is begun: () Only persons knowledgeable in performing the required maintenance shall perform the work. () All electrical power to the dispensing devices, to the pump serving the dispensing devices, and to all associated control circuits shall be shut off at the main electrical disconnect panel. (3) The emergency shutoff valve at the dispenser, if installed, shall be closed. (4) All vehicular traffic and unauthorized persons shall be prevented from coming within 6 m (0 ft) of the dispensing device. This revised version of the submitter's proposal has been simplified and inspection intervals have been added. 30A- Log # Charles A. Sunderhaus, OPW Fueling Components Add the following paragraph: 6.6.x Aftermarket devices such as message/advertising covers shall not be added to the fuel dispensing nozzles. Problem: These large devices affect the sensitivity of the nozzle on impact with the ground. The use of these devices may cause spills and/or injuries. Fuel dispensing nozzles must be listed, part of the requirements for listing in UL84 is the impact testing where the nozzle valve must close on impact with the ground. Add a new to read: "Any modification of the dispensing nozzle shall be listed or approved by the manufacturer of the nozzle." The submitter's proposed language would prohibit any modification at all, even one that is proved to be safe and to not interfere with the proper functioning of the dispensing nozzle. The Technical Committee's version will allow such modification. 9

11 30A- Log #CP3 Revise 6.6. to read: "6.6. An automatic-closing-type hose nozzle valve, with a latch-open device and, listed in accordance with UL 84, Standard for Valves for Flammable Fluids, with or without latch-open device, shall be provided on island-type dispensing devices used to dispense Class I or Class II liquids. This modification reflects the Technical Committee's action taken on Subsection 6.6. during the prior document revision cycle; i.e., it corrects a long-standing error. 30A-3 Log #0 Charles A. Sunderhaus, OPW Fueling Components Revise text as follows: 6.6. At any installation where the normal flow of product may be stopped other than by the hose nozzle valve, the system shall include listed equipment with a feature that causes or requires the closing of the hose nozzle valve before product flow can be resumed or before the hose nozzle valve can be replaced in its normal position in the dispenser. The vast majority of the dispensers/systems are credit card readers or pay-at-the-pump features and meet this clause. The problem is that nozzles without this device are still being installed on these dispensers causing injuries and spills because the nozzles are returned to the dispenser in the open position. I propose to require one type of nozzle on all dispensers to eliminate confusion. Revise 6.6. to read: "6.6.* At any installation where an automatic closing-type dispensing nozzle is used, the nozzle valve the normal flow of product may be stopped other than by the hose nozzle valve, the system shall include listed equipment with a feature that causes or requires the closing of the hose nozzle valve before product flow can be resumed or before the hose nozzle valve can be replaced in its normal position in the dispenser. This revision to 6.6. ensures that the requirement applies to any situation where an automatic closing-type dispensing nozzle is used. 30A-4 Log #CP5 Revise to read: "6.6.4 Dispensing nozzles used at marine motor fuel dispensing facilities shall be of the listed automatic-closing-type hose nozzle valve without a latch-open device." This revised wording correlates with 6.6., as amended in Proposal 30A- (Log #CP3). 0

12 30A-5 Log #4 Jon Nisja, Northcentral Regional Fire Code Development Committee Revise text to read as follows: Fuel dispensing systems shall be provided with one or more clearly identified emergency shutoff devices or electrical disconnects. Each such disconnect shall be identified by an approved sign stating EMERGENCY PUMP SHUTOFF in in. (50 mm) red capital letters. Such devices or disconnects shall be installed in approved locations but not less than 6 m (0 ft) or more than 30 m (00 ft) from the fuel dispensing devices that they serve. Emergency shutoff devices or electrical disconnects shall disconnect power to all dispensing devices; to all remote pumps serving the dispensing devices; to all associated power, control, and signal circuits; and to all other electrical equipment in the hazardous (classified) locations surrounding the fuel dispensing devices. When more than one emergency shutoff device or electrical disconnect is provided, all devices shall be interconnected. Resetting from an emergency shutoff condition shall require manual intervention and the manner of resetting shall be approved by the authority having jurisdiction. Exception: Intrinsically safe electrical equipment need not meet this requirement. The proposed text is from.5.3. There is no specific guidance on the size of the sign. The text is consistent with current text within and provides specific requirements on the size of the letters on the sign. needed. The submitter has not presented evidence that specific guidance for the sign or its size is 30A-6 Log #6 Jon Nisja, Northcentral Regional Fire Code Development Committee Add a new 6.7. to read: Revise to read: Emergency Electrical Disconnect devices shall be located in an approved location and labeled with an approved sign stating EMERGENCY FUEL SHUTOFF. Shut-offs should be labeled as to their operation so they can be identified by attendants and/or patrons that may be required to use them. The location of these devices should be placed in a readily accessible location outside the building for use in an emergency. The location should be approved by the AHJ. approved location Section 6.7 already requires the device to be "clearly identified" and to be located in an

13 30A-7 Log #4 Jon Nisja, Northcentral Regional Fire Code Development Committee Revise text to read as follows: The occupancy classification of a motor fuel dispensing facility that is located inside a building or structure shall be a low general hazard industrial occupancy as defined in NFPA 0, Life Safety Code. NFPA 0 does not use the term low hazard industrial occupancy. Revise 7.3. to read: "7.3. Occupancy Classification. The occupancy classification of a motor fuel dispensing facility that is located inside a building or structure shall be a special purpose low hazard industrial occupancy as defined in NFPA 0, Life Safety Code." already characterizes motor fuel dispensing facilities as "special purpose industrial" occupancies, for purposes of applying the egress requirements of NFPA 0. The risk addressed by 7.3. is commensurate. 30A-8 Log #9 Jon Nisja, Northcentral Regional Fire Code Development Committee Revise text to read as follows: Fixed Fire Protection. Automatic sprinkler protection installed in accordance with the requirements of NFPA 3, Standard for the Installation of Sprinkler Systems, shall be provided in major repair garages, as herein defined, when any of the following conditions exist: () The building housing the major repair garage is two or more stories levels in height, including basements, and the aggregate area of all levels combined exceeds,000 ft any one of the floors exceeds 930 m (0,000 ft ). () The major repair garage is one story and exceeds 5 m (,000 ft ). (3) The major repair garage is servicing vehicles parked in the basement of the building. Subsection should clarify that the requirement applies to the entire building; the entire building does not have to be used as a repair garage to utilize this requirement. The current language of section would allow a large area without sprinkler protection. (Example: 3 story building, 9,000 ft per floor would not require sprinkler protection.) The submitter has provided no justification or fire incident data to support this amendment. Also, the threshold areas now in are identical to those in the model building codes. The Technical Committee notes that the submitter has submitted two different proposals on 7.4.6, each with different criteria. See Proposal 30A-9 (Log #7).

14 30A-9 Log #7 Jon Nisja, Northcentral Regional Fire Code Development Committee Revise text to read as follows: Automatic sprinkler protection installed in accordance with the requirements of NFPA 3,, shall be provided in major repair garages, as herein defined, when any of the following conditions exist: () The major repair garage is two or more stories in height, including basements, and any one of the floors exceeds 930 m (0,000 5,000 ft ). () The major repair garage is one story and exceeds 5 m (,000 5,000 ft ). (3) The major repair garage is servicing vehicles parked in the basement of the building. Repair garages typical handle, store, and use flammable and combustible liquids at or below their flashpoints. The sprinkler thresholds for requiring automatic fire sprinklers should be lowered to 5,000 square feet. This would contain fires in repair garages and permit occupants to escape from below grade pits or areas with greater safety. The submitter has provided no justification or fire incident data to support this amendment. Also, the threshold areas now in are identical to those in the model building codes. The Technical Committee notes that the submitter has submitted two different proposals on 7.4.6, each with different criteria. See Proposal 30A-8 (Log #9). 30A-30 Log #CP9 Revise to read: "Where major repairs are conducted on the fuel systems of CNG-fueled vehicles or LNG-fueled vehicles, open flame heaters or heating equipment with exposed surfaces having a temperature in excess of 399 C (750 F) shall not be permitted in areas subject to ignitible concentrations of gas. This change clarifies the intent of this requirement. The Technical Committee has determined that this proposed amendment should be directed for action to the Task Group charged with developing amendments to Chapter, as this amendment should also address gaseous and liquid hydrogen fuels. As currently proposed, it is not complete. 3

15 30A-3 Log # Thomas P. Hammerberg, Automatic Fire Alarm Association, Bruce Fraser, Shane M. Clary Revise the accepted text and add a new 7.7.3: The circuits required by 7.7. shall be required to be monitored for integrity in accordance with NFPA 7. Renumber the existing to Due to the nature of this type of system, the circuits required by need to be monitored for integrity so that if there is a fault on the circuit wiring, a trouble signal will be generated at the protected premises. Add a new to read: " The circuits of the detection system required by shall be monitored for integrity in accordance with NFPA 7." This accomplishes the submitters intent without rearranging the current text. 4

16 30A-3 Log # Thomas P. Hammerberg, Automatic Fire Alarm Association, Bruce Fraser, Shane M. Clary Revise the accepted text and add a new 7.7.4: This system shall be electrically supervised by the building's fire alarm system, where present. It shall be a supervisory signal. Renumber the existing as required. This system needs to be electrically supervised by the building's fire alarm system. The proposed text does not require that fire alarm system be installed for this purpose, but if one is present, the Gas Detection System needs to be supervised. The Gas Detection System may be in another part of the protected premises. The action taken on Proposal 30A-3 (Log #) accomplishes the intent of this proposal. 5

17 30A-33 Log #CP7 Revise Section 8.3 to read as follows: "8.3 Installation in Classified Locations Where Class I liquids are stored, handled, or dispensed, electrical wiring and electrical utilization equipment shall be designed and installed in accordance with the requirements for Class I, Division or Division classified locations, as set forth in Table 8.3. and in NFPA 70, National Electrical Code. Exception: The storage, handling, and dispensing of methyl alcohol based windshield washer fluids shall not cause an area to be designated as a hazardous (classified) location. 8.3.* Table 8.3. shall be used to delineate and classify areas for the purposes of installing electrical wiring and electrical utilization equipment where Class I liquids are stored, handled, or dispensed. (See also Figure 8.3..) A designated classified area, as specified in Table 8.3., shall not extend beyond a floor, wall, roof, or other solid partition that has no openings The area classifications given in Table 8.3. shall be based on the premise that the installation meets the applicable requirements of this code in all respects. Should this not be the case, the authority having jurisdiction shall be permitted to determine the extent of the classified area All electrical wiring and electrical utilization equipment that is integral with the dispensing hose or dispensing nozzle shall be approved for use in Class I, Division classified locations Where Class I liquids are stored, handled, or dispensed, electrical wiring and electrical utilization equipment shall be designed and installed in accordance with the requirements for Class I, Division or Division classified locations, as set forth in Table 8.3. and in NFPA 70, National Electrical Code. Exception: The storage, handling, and dispensing of methyl alcohol based windshield washer fluids shall not cause an area to be designated as a hazardous (classified) location." Rest of text remains unchanged. This revision clarifies and emphasizes that Table 8.3. applies only to Class I liquids. 6

18 30A-34 Log #3 Marshall A. Klein, Marshall A. Klein & Associates, Inc. The purpose of this Tentative Interim Amendment is two-fold: it is intended to extend the utility of Table 8.3., which specifies the extent of hazardous (classified) locations in motor fuel dispensing facilities and automotive repair garages, by incorporating the (European) Zone system of designating hazardous (classified) locations and the allowable wiring methods and electrical utilization devices that can be used in them. It is also intended that this be done in a timely fashion, so that this revised table can be proposed for incorporation, as extracted text, into the 0 edition of the (NEC). This latter will be accomplished by means of a public comment to be submitted by the Technical Committee on Automotive and Marine Service Stations to its existing proposal to the NEC. The Technical Committee on Automotive and Marine Service Stations has revised Table 8.3. by adding a new column in which the proper Zone designations are given. Since is used internationally, the Technical Committee considers it important that provide accurate and compatible information in this regard. This will assist users when specifying equipment and devices in the international market. The addition of the Zone designations to Table 8.3. has been done in a manner to correlate with Article 505 of the NEC. The Technical Committee has also taken the opportunity to reorganize and simplify the Table so that it is easier to understand and interpret. For example, the descriptions of Extent of Classified Area have been editorially revised so that they use the same grammatical terminology. The Technical Committee has added several additional footnotes to the Table to further clarify the entries in the table, their application, and their relationship to NEC Articles 5 and 54. The Technical Committee on Automotive and Marine Service Stations considers it imperative that there be no inconsistencies between Table 8.3. of and Table 54.3(B)() of the NEC. The latter is extracted from the 008 edition of. Because the NEC is in the Annual 00 revision cycle and is in the Annual 0 revision cycle, the Technical Committee must process this change as a TIA. Otherwise, the revisions to Table 8.3. cannot be incorporated into the NEC until the 04 edition of that Code. It is the opinion of the Technical Committee that this meets the criterion of 5.(b) of the. The Technical Committee also believes that this TIA meets the criterion of 5.(e) of the by recognizing the use of the Zone concept in motor fuel dispensing facilities and repair garages. The Technical Committee notes that this has already been accomplished in other related documents, such as NFPA 30,, and NFPA 33,.

(b) ***Insert 30A_L_Figure8.3.(b) here*** The existing figure 8.3. does not cover all types of dispensers. Above ground tank with a dispenser is a common use in United States. There is a misinterpretation of the classified areas. This new figure will help resolve that problem. The proposed classification scheme conflicts with the criteria in Table 8.3. for aboveground tanks.
