Radiation Protection System Preventative Maintenance Checklist
Annual Inspections
Cable Inspection (All Systems)
Cable Replacement
1. The balancer cable used to suspend the body shield should be inspected once
annually by TIDI Products authorized personnel.
2. As a result of long-term use, the cable should be replaced after an extended
period of time to reduce the risk of fatigue failure. The replacement interval is
based on the design features of your system. Refer to the section titled System
Feature (Body Shield Balancer Swivel) on page 54 to determine if your system
is equipped with a body shield balancer swivel.
a. For systems that do not contain the body shield balancer
swivel feature, it is recommended to replace the cable once
every 4 years. Frequent use of the system and / or damage
may require more frequent replacement of the cable.
Cable Inspection
WARNING! RADIATION HAZARD
The Body Shield must be handled with care to avoid damage to the Body
Shield protective lead material. If the Body Shield is damaged, it must
be inspected according to the Body Shield and Face Shield Fluoroscopy
Inspection section of the User’s Guide (TIDI Products document 84000).
WARNING! INJURY RISK-CABLE HAZARD
Excessive rotation of Body Shield may cause Balancer Cable to break.
The Body Shield must be lowered and allowed to unwind after each use, in
an unlocked position. Annual inspections must be performed on the cable.
Cables must be replaced if there are signs of wear.
1. While the system is not in use, remove the body shield from its fixed position
inside the balancer. Lower the body shield until the bottom of the shield is
approximately 6 inches from the ground.
2. With the body shield lowered, use a Philips Screwdriver to remove the
(8) 10-32 .50 SS 18-8 panhead screws from the balancer cover removing both
cover pieces. (Figure 1)
3. Figure 2 is an example of a new cable for comparison.
4. Inspect the visible cable surfaces for any abnormalities. Abnormalities may
include:
a. Damage to the outer coating of the cable (Figure 3 ) (Figure 4 )
(Figure 5 )
b. Color variation from one part of the cable to the other (Figure
3)
c. Bulging areas (dimples and / or blisters) of the cable (visual or
by running fingers along the cable) (Figure 4) (Figure 5)
d. Stretched areas of the cable (visual or by running fingers along
the cable) (Figure 5)
5. Put the cover pieces back in place with the (8) screws after inspection.
