1.1 Inclusions
Note: See Annex F for explanatory material.
1.1.1 Vehicle maintenance
This Code applies to the portions of a motor vehicle maintenance facility where hydrogen gas-fuelled vehicles and hydrogen transport trailers are maintained, repaired, or stored during maintenance or repair, including areas and systems ancillary thereto. If a vehicle being maintained has multiple fuels and one of the fuels is compressed hydrogen gas, then the requirements of this Code would apply.
Note:
See Annex F for explanatory material.
See Annex A for facilities for large storage capacity vehicles and trailers.
1.1.2 Vehicle parking
This Code also contains information on private parking structures where hydrogen gas-fuelled vehicles are parked or stored, including areas and systems ancillary thereto. See Annex D.
1.1.3 Parking structure requirements
For purposes of this Code, private parking structures have the same requirements as minor repair areas.
1.2 Exclusions
The scope of this Code does not include
a) indoor or outdoor refuelling operations;
b) open parking structures;
c) public parking structures of any construction;
d) other fuels used for vehicles; or
e) liquid hydrogen (LH2) vehicles;
f) natural gas vehicle maintenance facilities, which are covered in CSA B401.1;
g) propane vehicle maintenance facilities, which are covered in CSA B401.2; or
h) battery electric vehicle maintenance facilities, which are covered in CSA B401.4.
Note: See Annex F for explanatory material.
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 gaseous hydrogen (GH2) inside motor vehicle maintenance facilities.
Note: See Annex F for explanatory material.
1.4 Terminology
The terms “fuelling” and “refuelling” are used interchangeably in this Code. The terms “park” and “store” and all derivatives thereof are used interchangeably in this Code.
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) IEEE/ASTM SI 10 or ISO 80000-1 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) Ft/in conversions will be rounded to the nearest full inch using traditional rounding conventions.
5) Pressures will be rounded to the nearest whole value using traditional rounding conventions.
6) 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
All references to pressure throughout this Code are to be considered gauge pressures, unless otherwise specified.
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.
Note: See Annex F for explanatory material.
