23Compliance
1.2.1.1. Compliance with the Code1) Compliance
with this Code shall be achieved by a)
complying with the applicable acceptable
solutions in Division B, or b) using
alternative solutions that will achieve at least
the minimum level of performance required by
Division B in the areas defined by the objectives
and functional statements attributed to the
applicable acceptable solutions.

26Functional Statements
3.2.1.1. Functional Statements1) The objectives
of this Code are achieved by measures, such as
those described in the acceptable solutions in
Division B, that are intended to allow the
building or its elements to perform the following
functions (see Appendix A) F03 To retard the
effects of fire on areas beyond its point of
origin.
Alastair J. M. Aikman P.Eng. AIKMAN ENGINEERING
27Functional Statements
Structural statements
F20 To support and withstand expected loads and
forces. F21 To limit or accommodate dimensional
change. F22 To limit movement under expected
loads and forces. F23 To maintain equipment in
place during structural movement.
Alastair J. M. Aikman P.Eng. AIKMAN ENGINEERING
28Functional Statements
Miscellaneous statements
F12 To facilitate emergency response. F34 To
resist or discourage unwanted access or entry.
F35 To facilitate the identification of
potential intruders. F40 To limit the level of
contaminants. F50 To provide air suitable for
breathing. F72 To provide facilities for the
sanitary disposal of human and domestic wastes.

33Intent Statements
OH2.1 Exposure to human or domestic waste
a) have an area not more than 60 of the
cross-sectional area of the chute To limit the
probability that large linen or refuse objects
will be introduced into the chute, which could
lead to such objects becoming lodged in the
chute, which could lead to bacteria growth,
insect infestation or foul odours, which could
lead to unsanitary conditions, which could lead
to harm to persons.

OS1 - Fire Safety b) be fitted with closures
designed to close automatically and latch after
use. To limit the probability that a fire will
spread from a shaft containing a linen chute or
refuse chute through intake openings to other
parts of the building, which could lead to harm
to persons in other parts of the building.
