1.6
This Standard does not purport to address all of the safety problems associated with its use. It does not set out requirements relating to the safety of the person installing the units.
1.7
This Standard assumes that its users are familiar with the terminology, procedures, and requirements of good building practice.
It further assumes familiarity with sealants and sealing, glass handling procedures, painting, where applicable, and an understanding of the fundamentals of residential construction that affect the installation of windows, doors, or unit skylights.

This Standard does not address the qualifications and skills that an installer should possess.
It is the responsibility of the users of this Standard to review and establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

In CSA Standards, “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; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability.
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.
