NFPA 58-2014 Substantive Changes

Bulk and Industrial Plantsf G 3.3.10 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 atprior to further distribution as a liquid for use at other facilities.

3.3.34* Industrial Plant. A facility that stores LP-Gas yin containers of more than 4000 gal water capacity for use at the facility or to distribute vapor to other facilitiesfacilities.

Bulk and Industrial Plants 3.3.10 Bulk Plant and 3.3.34 Industrial Plant are

modified to eliminate confusion in applying container appurtenance and site security requirementsappurtenance and site security requirements.

A.3.3.34 Industrial plant includes all facilities that use gas on site, including plants, farms, engine fueling g g p g gstations, schools, hotels, and other locations.

Container appurtenances now determined only by i i li icontainer size, not application.

5.7.4.1 – 4000 gal wc and less 5 7 4 2 Greater than 4000 gal wc 5.7.4.2 – Greater than 4000 gal wc

Cathodic Protection of Piping Underground steel piping larger than 1 in. nominal must

be protected by cathodic protection systemC f 1 Cathodic protection optional for piping 1 in. and smaller

material, painted or otherwise protected

T k H tTank Heaters New definition added, requirements expanded 3.3.73 Tank Heater (Indirect and Direct Types). A

device used to apply heat either directly to a portion of th t i f i t t ith LP G li idthe container surface in contact with LP-Gas liquid or indirectly by circulating LP-Gas liquid from the container to the device and then back to the containercontainer to the device and then back to the container.

3.3.73.1 Direct Gas-Fired Tank Heater. A gas-fired device that applies heat directly to the container surface in contact with LP-Gas liquid.

T k H t 5 21 4Tank Heaters – 5.21.4 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 containersLi it t l ( h d) Limit control (unchanged)

Electric immersion heaters must automatically shut off if liquid level falls below top of heateroff if liquid level falls below top of heater

Direct gas-fired tank heaters must be removable for tank inspectionp

T k H t 5 21 4Tank Heaters – 5.21.4 Direct gas-fired tank heaters for outdoor, aboveground g g

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 extinguishedextinguished

On containers greater than 1000 gal wc, automatic safety shutoff to stop flow of gas if container becomessafety shutoff to stop flow of gas if container becomes empty of liquid

LP-Gas Pumps New equipment design requirements 3.3.19 Design Pressure. The maximum pressure at

which the equipment or system is designed to operate.

New 5 17 2 and 5 17 3 specify equipment design New 5.17.2 and 5.17.3 specify equipment design pressure for pump and bypass valve based on maximum differential pressure produced by the p p ypump

Installation requirements unchanged

Facility Hose 3 3 22 – a hose permanently installed for the 3.3.22 – a hose…permanently installed for the

purpose of unloading product from CTMVs in non-metered service into a bulk plant or industrial plant.

6.19.2.6 (formerly 6.18) – facility hose or the facility shall be equipped with an emergency discharge

t l t th t ill h t d th fl f LP Gcontrol system that will shut down the flow of LP-Gas caused by complete separation of the facility hose within 20 seconds without the need for humanwithin 20 seconds without the need for human intervention

Derived from DOT regs (49 CFR 173) for hoseinstalled on some CTMVs

Concrete Pad New definition – A foundation consisting of solid

concrete or masonry blocks, a placed concrete slab, or a poured concrete foundationor a poured concrete foundation.

Previously undefined Definition addresses enforcement problems related Definition addresses enforcement problems related

to 6.6.3.1(G)

Vehicular Barrier Protection Previous language was not consistent

Protection against vehicular impact Protect where vehicle traffic expected Protect against physical damage

Wid f i t t ti f t bl Wide range of interpretations for acceptable protection methods and scenarios

V hi l B i P t tiVehicular Barrier Protection

3.3.79* A system or method to provide physical protection for LP-Gas storage areas or installations from p gvehicular incursion.

A.3.3.79 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 ith regard to the kinds of traffic that can beconditions 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:limited to, the following:

(1) Guard rails(2) Steel bollards(3) R i d id lk ( i i f 6 i i h i h )(3) Raised sidewalks (minimum of 6 in. in height)(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)(8) Parking bumpers (minimum of 6 in. in height) (9) Fencing/gates

Vehicular Barrier Protection Requirements made consistent: 6.6.6.1 – Underground or mounded containers 6.25.3.13 – Liquid dispensers 8.4.2.2 – Cylinder exchange cabinets 6.25.3.13 – also added prescriptive requirements

Concrete-filled steel guard posts S d t th 4 ft t Spaced not more than 4 ft apart

CLeak Check and Pressure Test New requirements added to ensure that

“outside” piping is tested for pressure containment and leakage.D fi iti d i t b t ti ll Definitions and requirements substantially extracted from NFPA 54-2012.

3 3 37 Leak Check An operation performed on 3.3.37 Leak Check. An operation performed on a gas piping system to verify that the system does not leak.

3.3.59. Pressure Test. An operation performed to verify the gastight integrity of gas piping f ll i it i t ll ti difi tifollowing its installation or modification.

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 testin the pressure test
