1.2.12 Foot traffic
Avoid walking on insulated pipes, as this can
damage the insulation. Damage caused by foot
traffic includes dented sheet cladding and gaps at
the sheet seams. Water can penetrate the
insulation through these gaps and cause lasting
damage to the entire insulation system. The result
is often greater heat losses and corrosion.
Note
An insulation system resistant to foot traffic
must not become permanently damaged if a
person weighing 220 lbs (100 kg), (weight
including any tools being carried) walks on it.
It is not designed to bear additional loads,
such as the placing of heavy equipment. For
the purpose of the safety regulations, a
durable insulation is not considered to be a
walkable surface.
In special applications, reinforcing the cladding is
recommended, e.g. using a reinforcement sheet.
Pipe insulation systems resistant to foot traffic
require an insulation material with a high
mechanical strength (e.g. ProRox
® PS 980 NA pipe
sections). Using other insulation materials such
as wired mats, which are not resistant to
pressure, is not recommended, as the sheet
cladding only rests on the spacers and tends
to dent when walked upon.
