||Handrailing shall be so designed
and so installed that it safely supports all loads to which
it is likely to be subjected in service. The principle of
the design shall be to establish design loads by applying
appropriate factors of safety to appropriate nominal loads
and then to determine the structural resistance required by
the handrailing, set
out in the structural guidlines for balustrading by the South
African Burau of Standards (SABS0104)
shall be so installed that the finish is smooth and such that
it cannot damage a wet chamois skin run along surfaces and
edges exposed to body contact.
shall be so installed that it is clearly visible at a distance
of up to 7,5 m. The minimum dimension that is clearly visible
from a distance of 7,5 m is 20 mm. If the elements of the
handrailing have a diameter of less than 20 mm, for example
when wire rope is used, signs should be attached to the handrailing
to ensure that it is clearly visible.
shall provide the means for attaching handrailing in such
a way that all loads are transmitted to the supporting structure.
Foundation failures are potentially more hazardous than failure
of a single element or component because the failure of a
foundation can affect the stability of the entire handrailing
system. An example of a foundation failure is where a concrete
upstand beam does not support the handrailing adequately because
of concrete spalling, shallow embedment of anchorages or inadequate
reinforcing in the concrete.
