such as the following defects shall be immediately removed from service:
(a) Cracks at welds;
(b) Cracked or broken components;
(c) Bent or sprung components caused by mishandling, abuse, tire explosion, or rim wheel separation;
(d) Pitting of components due to corrosion; or
(e) Other structural damage which would decrease its effectiveness.
d.
Restraining devices or barriers removed from service shall not be returned to service until they are repaired and
reinspected. Restraining devices or barriers requiring structural repair such as component replacement or rewelding
shall not be returned to service until they are certified by either the manufacturer or a Registered Professional
Engineer as meeting the strength requirements of step 4c.

The employer shall furnish and ensure that an air line assembly consisting of the following components be used for
inflating tires:
(a) A clip-on chuck;
(b) An in-line valve with a pressure gauge or a pre-settable regulator; and

employee to stand outside the trajectory.
f.
Current charts or rim manuals containing instructions for the type of wheels being serviced shall be available in the

compatibility prior to assembly of the rim wheel.
6.

The employer shall establish a safe operating procedure for
servicing multi-piece rim wheels and shall ensure that employees are instructed in and follow that procedure. The
procedure shall include at least the following elements:
a.
Tires shall be completely deflated before demounting by removal of the valve core.
b.
Tires shall be completely deflated by removing the valve core before the rim wheel is removed from the axle in either
of the following situations:
(1) When the tire has been driven under-inflated at 80% or less of its recommended pressure, or
(2) When there is obvious or suspected damage to the tire or wheel components.
c.
Rubber lubricant shall be applied to bead and rim mating surfaces during assembly of the wheel and inflation of the
tire, unless the tire or wheel manufacturer recommends against it.
