CSA Group CSA B401.2:24 National Standard of Canada Propane on-road vehicle maintenance facilities code

Preface

This is the second edition of CSA B401.2, Propane on-road vehicle maintenance facilities code. It supersedes the previous edition published in 2021.

The following are the major changes to this edition:

a) subclause titles have been added for accessibility;

b) the term “container” has been removed in favour of “tank” throughout the document;

c) the requirements in absence of a local building code have been clarified; and

d) the terms “motor vehicle” and “tank” have been defined.

This Code was prepared by the Subcommittee on Propane Vehicle Maintenance Facilities Code, under the jurisdiction of the Technical Committee on Autogas/DME Transportation and the Strategic Steering Committee on Transportation, and has been formally approved by the Technical Committee and the Interprovincial/Territorial Gas Advisory Council (IGAC).

This Code has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Notes:

1) Use of the singular does not exclude the plural (and vice versa) when the sense allows.

2) Although the intended primary application of this Code is stated in its Scope, it is important to note that it remains the responsibility of the users of the Code to judge its suitability for their particular purpose.

3) This Code was developed by consensus, which is defined by CSA Policy governing standardization — of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full agreement with all clauses of this Code.

b) provide an explanation of circumstances surrounding the actual field condition; and

c) where possible, phrase the request in such a way that a specific “yes” or “no” answer will address the issue.

Committee interpretations are processed in accordance with CSA Directives and guidelines governing standardization and are available on the Current Standards Activities page at standardsactivities.csagroup.org.

5) This Code is subject to review within five years from the date of publication. Suggestions for its improvement will be referred to the appropriate committee.

1 Scope

1.1 Inclusions

This Code applies to the portions of a motor vehicle maintenance facility where propane-fuelled on-road vehicles are maintained, repaired, or stored during maintenance or repair, including ancillary areas and systems. This applies to where the fuel system is for motive power of the vehicle.

1.2 Exclusions

This Code does not apply to

a) motor vehicle repair procedures;

b) parking facilities;

c) facilities where motor vehicle maintenance is not the primary purpose;

d) repair of vehicles where the Transport Canada (TC) or Department of Transportation (DOT) cylinder can be removed, as this content can be found in CSA B149.2;

e) other fuels used for vehicles;

f) propane when used for other purposes such as cooking, space, or water heating; or

g) repairs in outdoor spaces, as this content can be found in CSA B149.2.

Note: Requirements for the storage, handling, and transferring of propane can be found in CSA B149.2.

1.3 Purpose

The purpose of this Code is to provide reasonable means to manage the risks associated with the maintenance and repair of vehicles fuelled with propane inside motor vehicle maintenance facilities.

1.4 Terminology

1.4.1 Fuelling and refuelling

The terms “fuelling” and “refuelling” are used interchangeably in this Code.

1.4.2 Fuel composition

Where the term “propane” is used, the requirements of this Code include, and apply equally to, any fuel that is composed predominantly of any of the following hydrocarbons or a mixture of them:

a) propane;

b) propylene;

c) butane (either normal butane or isobutane); and

d) butylenes.

1.5 Units of measure

The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for information and comparison only.

Notes:

1) CSA B149.5 can be used as a guide when converting imperial units to metric units.

2) Less than 1 m will be shown in mm.

3) 1 m or more will be shown in m to the nearest 0.1 m.

4) Pressures will be rounded to the nearest whole value using traditional rounding conventions.

5) Where the word “gallon” is used in this Code, it indicates a U.S. gallon equivalent to 3.785 L water capacity.

1.6 Gauge pressure

Unless otherwise specified, all references to pressure throughout this Code are to be considered gauge pressures.

1.7 Mandatory language

In this Code, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Code; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Code.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
