B149.2-15 Propane storage and handling code & FS-XXX-15 Amendments

[Admin]

You can download the FS-XXX-15 Proposed Propane Code Adoption Document  - Here

The amendment was to become effective on Jan 1, 2016, but as far as I know no official Orders have been released.

I reviewed the new B149.2-15 code book and will post any changes or additions it has in comparison to the B149.2-10.  The Propane Code amendment above would supersede the B149.2-15.  The B149.2-15 can be purchased from the CSA Website.

The changes I list below are the sections of the Code book that were marked with the triangle symbol.

In this 2015 edition, where a major change or addition to the previous edition of the Code has been made, the clause, table, or figure affected is identified by the symbol delta (*triangle) in the margin. Users of the Code are advised that the change markers in the text are not intended to be all-inclusive and are provided as a convenience only; such markers cannot constitute a comprehensive guide to the revisions made to the Code. Care must therefore be taken not to rely on the change markers to determine the current requirements of the Code. As always, users of the Code must consider the entire Code and any local amendments.

A ventilated cabinet, an enclosure, or fencing used in conjunction with a tank shall be locked when unattended.

7.19.1.5
A service valve normally located under the dome of a tank shall
(a) have the outlet opening plugged unless it is to be used
(i) for vapour withdrawal service; or
(ii) as a connection for the pump bypass piping; and
(b) not be used for both vapour withdrawal service and as a connection for the pump bypass piping at the same time.

7.19.1.6
At least one portable fire extinguisher of not less than 20-B, C rating shall be installed in a readily accessible location at a container refill centre.

A kiosk doorway shall not be located within 10 ft (3 m) of any point of transfer it faces.

7.19.4.4
Barriers, other than those specified in Clauses 7.19.4.1 and 7.19.4.2, that provide an equivalent level of protection may be used. Equivalency may be demonstrated by physical testing or engineering analysis.

7.20 Dispensing system

7.20.1
A propane dispensing system shall be located at least
(a) 10 ft (3 m) from
(i) a property line;
(ii) a drainage basin or ditch;
(iii) any noncombustible building wall; and
(b) 25 ft (7.6 m) from a combustible building wall unless approved fire protection is provided.

7.20.2
A propane dispenser or vehicle fuel dispenser located on an island shall be protected from damage with the use of posts
(a) as stipulated in Clause 7.19.4.1, Items (b) to (d); and
(b) located to provide a minimum of
(i) 1 ft (300 mm) of clear space between the posts and the propane dispenser; and
(ii) 42 in (1080 mm) of clear space between the posts and propane dispenser located on an island that incorporates a cylinder filling scale. As an alternative to Items (a) and (b), a propane dispenser or vehicle fuel dispenser used for vehicle filling and located on an island shall have the pump and the ISC valve interlocked so that the valve is closed when the pump is not running, and the ends of the island shall be protected with posts in accordance with Clause 7.19.4.1. The island shall be made of concrete and shall be a minimum of 3.5 in (9 cm) above the vehicle-travelled portion of the area adjacent to the vehicle fuel dispenser. See Annex N. When purging equipment is provided, a vent pipe shall be installed to discharge the vapours to an ignition-free location at least 10 ft (3.m) from the propane dispenser.
Note: Vehicles are not normally considered a source of ignition within the dispensing zone, provided that the engine and any source of ignition is turned off before and during the refuelling. The person who is filling or purging any propane container is responsible for ensuring that there is no source of ignition within 10 ft (3 m) measured horizontally.

7.20.3
A piping system, located below grade, from a tank to a propane dispenser located on an island shall be installed
(a) underground in accordance with the provisions of Clause 6.15 of CSA B149.1; or

7.20.4
Except as specified in Clause 7.19.3(b), and except when the dispensing system is activated, the internal safety control valve serving the propane or vehicle fuel dispenser shall remain closed. The propane or vehicle fuel dispenser and internal safety control valve shall be interlocked either electrically or pneumatically. Other means of shutting off the fuel system shall be used on the piping system serving the propane dispenser or vehicle fuel dispenser when closure of the internal safety control valve can interrupt other services. This shutoff device shall be located as close as practical to the tank and interlocked with the propane dispenser or vehicle fuel dispenser as above.

Procedures shall be established appropriate to tank systems, filling plants, container refill centres, and other facilities where liquid propane is piped to a vaporizer or process, as follows:
(a) operating procedures sufficient to ensure safety and reliability in the day-to-day operation of the facility; and (b) maintenance procedures, covering testing, inspection, monitoring, and documenting the equipment, its repair and general upkeep.

7.22.2 Documentation of procedures
The procedures in Clause 7.22 shall be documented in a form appropriate to the particular facility in notices, manuals, guidelines, or other recorded instructions on view or readily available at the facility.
Note: See Annex L on risk and safety management plans.

7.22.3 Review and maintenance of procedures
The procedures shall be modified when necessary because of equipment or organizational changes, and reviewed as required.

9.2.3
The heating medium piping connected to an indirect vaporizer shall be provided with backflow preventers and phase separators to prevent the flow of propane into such piping. When an indirect vaporizer is installed in a building, the phase separators shall be installed outdoors or shall be vented outside.

9.2.5
If the heat source of an indirect-fired vaporizer is a source of ignition, is not certified for hazardous locations, and is located within 15 ft (4.5 m) of the vaporizer, the vaporizer and its heat source shall be installed as a direct-fired vaporizer.

[Admin]

It seems the proposed Propane CAD amends Section 7.2 by adding Clause 7.2.5;

7.2.5
Relief valves shall be inspected and inspection recorded at a minimum interval of every five (5) years. The process as per "Pressure Relief valve (PRV) Replacement Intervals, Visual Inspections and Data Collection Requirements for Propane Tanks" published by Canadian Propane Association, January 2015, shall be followed.

I'm not sure what happens to the existing Clause 7.2.5 found in the B149.2-10 & B149.2-15, as it was never revoked;

7.2.5
A loose-fitting rain cap shall be provided for all tank relief valves.

The B149.2.15 with FS-224-17 Amendments become effective July 1, 2017.
