The application of this Standard requires a working knowledge of applicable federal, provincial, and local building codes and regulations specifically concerning, but not limited to, required means of egress and requirements for safety glazing.
This Standard does not apply to the
(a) selection of windows, doors, or unit skylights for a given application
(b) selection of other products for use in the installation
(c) installation of storm windows or storm doors
(d) maintenance of installed windows, doors, or unit skylights or

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.
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.
