APPLICATION:
Attachment of handrails to wood studs or blocking
that serve a single dwelling unit, in buildings to which Part 9 applies [see Sentence
1.3.3.3.(1) of Division A for application of Part 9].
This also applies to handrails serving dwelling units in buildings to which Part 3 applies [see Sentence
1.3.3.2.(1) of Division A for application of Part 3], as
stated in Sentence
3.3.4.7.(1).
INTENT:
To limit the probability of excessive spacing or inadequate
placement of fasteners, or insufficient withdrawal resistance of fasteners,
which could lead to:
- the excessive deflection or dislodgement of handrails under normal use, which could lead to persons falling, or
- the excessive deflection or dislodgement of handrails being used by persons in an emergency situation, which could lead to delays in the evacuation or movement of persons to a safe place.
This is to limit the probability of harm to
persons.
