CSA/ASC B651:23

Purpose 1.1 Purpose This Standard specifies technical requirements on how to make buildings and the exterior built environment accessible and safely usable by persons with physical, sensory, or cognitive disabilities. Notes: 1) Temporary buildings and facilities provided for public use should also comply with the technical requirements of this Standard. Such temporary facilities can include teaching spaces, reviewing stands, exhibit areas, bleachers, first aid facilities, and pedestrian passageways around construction sites, as well as temporary accommodations such as shelters. 2) Where public access is permitted during construction, renovation, or maintenance of a facility or an exterior environment, the requirements of this Standard should be respected to provide safe and equitable use for everyone. 3) Some people with disabilities could have requirements beyond the levels addressed in this Standard. 1.2 Application This Standard describes technical requirements that can be used in the design and construction of new facilities or exterior environments, or in modifications to existing facilities or exterior environments. This Standard does not address the application of the technical requirements. The extent to which these requirements are to be applied is the responsibility of other AHJs. 1.3 Dimensions The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only. This Standard contains minimum requirements based on adult dimensions. Where converted from non-SI units, values have been rounded off with respect to critical dimensions. All dimensions in figures are given in millimetres (mm) and are measured to the centreline, unless otherwise specified. Notes: 1) When designing for specific individuals, their particular abilities and preferences should be taken into account. For example, some people prefer to transfer to or from a wheeled mobility device towards their preferred side when using toilet facilities. 2) If a facility is primarily to serve children, dimensions and other provisions should be adjusted to make them suitable for children. 1.4 Commentary and figures Commentary and figures are included for explanatory or illustrative purposes only and are not a mandatory part of the Standard. Figures are not to scale. If there is any difference between the text and a figure (where provided), the text shall take precedence. 1.5 Annexes Annexes A to C provide additional information on topics considered in the Standard. Annex D provides guidance for the design of outdoor trails and beach access routes. Annex E contains references for accessible outdoor recreational environments to supplement the information and guidance provided in Annex D. 1.6 Terminology In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "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 Standard. Commentary accompanying clauses do not include requirements or alternative requirements; the purpose of a commentary accompanying a clause is to separate explanatory or informative material. Text accompanying tables is considered part of the table and may be written as a requirement. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.7 Large print Consistent with the recommendations of the CSA/ ASC B651 series of Standards and for ease of reading, this Standard has been printed in a 14 pt font size.
