141 This single-piece wheel is mainly used with tubeless tyres. Figures 25 and 26
show typical wheels used on heavy goods vehicles. Figure 27 is typical of a type
used on light commercial vehicles. Tyre failure is occasionally experienced when
inflating tyres of this type and can lead to a severe air blast. Safety measures
include those for car tyres but include the additional precautions outlined in
paragraphs 142 to 144.
142 Use a restraining
device when you are
inflating above 15 psi,
such as:
n
n
n
a strong, firmly-
secured cage (see
Figure 29). Consider
lining this with mesh
to retain debris. For
fixed installations it is
helpful to mark the
safety exclusion zone
on the workshop
floor as a reminder to
staff (see Figure 24);
a secured horizontal stool and associated clamping mechanism; or
a portable restraint.
These are available
in the form of a
lightweight cover
(see Figure 28) that
encloses the tyre
and wheel rim and
may be particularly
advantageous for
off-site repairs. With
a bag restraint, in the
event of an explosion
the fabric expands
and dissipates the
blast while containing
projected debris.
Fabric devices may
need to be replaced
after an explosion.
