2 Overview NFPA Substantive Changes TIAs 2017 Edition

3 NFPA Substantive Changes

4 Bulk and Industrial Plants Bulk Plant. A facility that stores LP-Gas in containers of more than 4000 gal water capacity prior to further distribution as a liquid for use at other facilities * Industrial Plant. A facility that stores LP-Gas in containers of more than 4000 gal water capacity for use at the facility or to distribute vapor to other facilities.

5 Bulk and Industrial Plants Bulk Plant and Industrial Plant are modified to eliminate confusion in applying container appurtenance and site security requirements. A Industrial plant includes all facilities that use gas on site, including plants, farms, engine fueling stations, schools, hotels, and other locations. Container appurtenances now determined only by container size, not application. i gal wc and less Greater than 4000 gal wc

6 Cathodic Protection of Piping Underground steel piping larger than 1 in. nominal must be protected by cathodic protection system Cathodic protection optional for piping 1 in. and smaller South Carolina incident Liquid id piping i failure due to corrosion One fatality Aboveground piping constructed of corrosion-resistant resistant material, painted or otherwise protected

7 Tank Heaters New definition added, requirements expanded Tank Heater (Indirect and Direct Types). A device used to apply heat either directly to a portion of the container surface in contact t with LP-Gas liquid id or indirectly by circulating LP-Gas liquid from the container to the device and then back to the container Direct Gas-Fired Tank Heater. A gas-fired device that applies heat directly to the container surface in contact with LP-Gas liquid.

8 Tank Heaters Tank heaters must be approved for the application Tank heaters must be marked with rated input and maximum vaporizing capacity Manufacturer s instructions must clearly indicate use for heating LP-Gas containers Limit it control (unchanged) Electric immersion heaters must automatically shut off if liquid level falls below top of heater Direct gas-fired tank heaters must be removable for tank inspection

9 Tank Heaters Direct gas-fired tank heaters for outdoor, aboveground use only No direct flame impingement on the container Automatic safety shutoff (with manual reset) to stop flow of gas to the heater if the pilot flame is extinguished On containers greater than 1000 gal wc, automatic safety shutoff to stop flow of gas if container becomes empty of liquid

10 LP-Gas Pumps New equipment design requirements Design Pressure. The maximum pressure at which the equipment or system is designed to operate. New and specify equipment design pressure for pump and bypass valve based on maximum differential pressure produced by the pump Installation requirements unchanged

11 Facility Hose a hose permanently installed for the purpose of unloading product from CTMVs in nonmetered service into a bulk plant or industrial plant (formerly 6.18) facility hose or the facility shall be equipped with an emergency discharge control system that t will shut down the flow of LP-Gas caused by complete separation of the facility hose within 20 seconds without the need for human intervention Derived from DOT regs (49 CFR 173) for hose installed on some CTMVs

12 Concrete Pad New definition A foundation consisting of solid concrete or masonry blocks, a placed concrete slab, or a poured concrete foundation. Previously undefined Definition addresses enforcement problems related to (G)

13 Vehicular Barrier Protection Previous language was not consistent Protection against vehicular impact Protect where vehicle traffic expected Protect against physical damage Wide range of interpretations t ti for acceptable protection methods and scenarios New definition and annex material intend to clarify

14 Vehicular Barrier Protection ti * A system or method to provide physical protection for LP-Gas storage areas or installations from vehicular incursion.

15 A There are numerous effective means to provide protection for LP-gas installations from impact by motor vehicles. The system or method selected depends on local conditions with regard to the kinds of traffic that can be reasonably expected and the environment surrounding the location. Examples of such protection include, but are not limited to, the following: (1) Guard rails (2) Steel bollards (3) Raised sidewalks (minimum i of 6 in. in height) h (4) Fencing (5) Ditches (6) Berms (not to exceed 50 percent of the container perimeter) (7) Jersey barriers (8) Parking bumpers (minimum of 6 in. in height) (9) Fencing/gates

16 Vehicular Barrier Protection Requirements made consistent: Underground or mounded containers Liquid dispensers Cylinder exchange cabinets also added prescriptive requirements Concrete-filled steel guard posts Spaced not more than 4 ft apart Set at least 3 ft deep in concrete footing At least 3 ft tall At least 3 ft away from container

17 Leak Check and Pressure Test New requirements added to ensure that outside piping is tested for pressure containment and leakage. Definitions iti and requirements substantially ti extracted from NFPA Leak Check. An operation performed on a gas piping system to verify that the system does not leak Pressure Test. An operation performed to verify the gastight integrity of gas piping following its installation ti or modification.

18 Pressure Test 6.14 After installation or modification Pressure test at normal operating pressure LP-Gas is permitted to be used as the test medium NOTE: NFPA 54 does NOT allow LP-Gas to be used in the pressure test Where branches are installed, only the branch must be pressure tested Where NFPA 54 applies, use NFPA 54

19 Leak Check 6.15 Vapor systems operating at 20 psig or less only Immediately after gas is introduced to a new system or following an interruption in service Sample method Annex L Where NFPA 54 applies, use NFPA 54 Where leakage is indicated, fuel supply must be shutoff until necessary repairs are made

20 Small ASME Tank Location PRV on ASME container less than 125 gal wc cannot discharge in or beneath a building Subject of Successful Appeal (previously 6.3.7) restored which permits only cylinders to be installed under buildings w/ 50% perimeter open to atmosphere New requirement explicit on installation of small ASME containers

21 Automated Cylinder Exchange New requirements section 8.6 Must comply with requirements of 8.4 and 8.5 Electrical equipment inside storage cabinet must be Class I, Div 2. Does not impact electrical l classification of equipment installed near the exchange cabinet Cabinets designed to allow cylinder storage in upright position only

22 Unattended Facilities Facilities that are not attended Remote locations No personnel stationed on site Internal valves and emergency shutoff valves must be closed except when facility is in use Containers used for supplying a process or system exempted Vehicle fuel dispenser locations exempted

23 Miscellaneous Combustible materials shall not accumulate or be stored within 10 ft of a container. Long dry grass or weeds deleted d liquid inlet piping shall be designed to prevent debris from impeding the action of valves Fire extinguisher having a 40-B:C or 80-B:C rating and a minimum capacity of 18 lb dry chemical Consistent with NFPA 10 Distance from storage determined by rating

24 TIAs from 2011 Edition Now permanent parts of the code 4.4 Qualification of Personnel Cathodic Protection of Underground and Mounded Tanks 52111(C (Container construction) ti (I) (Installation) (Periodic testing)

25 Tentative Interim Amendments Issued With the Code

26 Testing ESVs Testing of Emergency Shutoff Valves Committee finalized language in ROC Concern that ROC language could be interpreted to mean that non-mandatory ESVs must be tested TIA added language to clarify that only the required ESVs specified in NFPA 58 must be tested

27 Stationary Engines Chapter 11 scope modified to address only vehicle engine applications Containers for stationary engines relocated to 6.26

28 Tentative Interim Amendments Issued Subsequent to the Code

29 Valves & Appurtenances Restructured Existing (A) and (B) combined into one paragraph (A). Deleted existing (C) so that all containers 4000 gal wc and less are equipped the same regardless of application Existing (D) becomes (B). Existing (D)(3) now applies only to containers greater than 125 gal wc.

30 Valves & Appurtenances Table delete column for gal wc now applies only to containers over 4000 gal wc Existing deleted in its entirety Result renumbered as Chapter 11 updated to reflect new structure and correct cross-references references
