Sentence 3.3.1.18.(2)

Intent 1:

To limit the probability that persons [e.g. children] will push their head or body through a guard and fall or become trapped or asphyxiated, which could lead to harm to persons.

Intent 2:

To exempt a guard from the limitation on the size of openings stated in the latter part of Sentence 3.3.1.18.(2) on the basis that it can be shown that the size of openings that exceed the limit does not present a hazard [e.g. children being able to push their head or body through a guard and falling or becoming trapped or asphyxiated].
