MAINTENANCE INSTRUCTIONS
4.1
Quarterly (Routine) and Annual (Complete) Maintenance Requirements
Radiographic exposure devices and associated equipment must be maintained regularly by trained and
qualified personnel to ensure consistent and safe operation of the radiographic system. The routine
inspection and maintenance also ensures that the integrity of the Type B(U)-96 and Type A transport
packages are maintained in compliance with the package certification numbers; USA/9296/B(U)-96,
CDN/E199/-96 and approval requirements, respectively.
Manufacturers base the recommended inspection and maintenance requirements on the system's design,
application, materials, anticipated work cycles, environmental factors of use under the normal and
abnormal conditions of industrial radiography and while in the transport system. A program of systematic
maintenance will prolong the working life of the radiographic exposure device and associated equipment
in addition to ensuring safety during use. By most national regulations, routine maintenance of the
systems is required at intervals not to exceed 3 months in addition to the radiographer's daily inspections
for obvious defects. The complete annual servicing ensures the integrity of the system.
Maintenance program administrators must recognize the need for maintenance intervals that are less
than the required 3-month interval especially in cases where the systems are used in severe
environmental conditions. Maintenance program administrators must ensure the systems are completely
serviced immediately after certain jobs in severe conditions. Extreme or severe conditions may include,
but is not limited to conditions where the equipment was:
• Immersed in water or mud.
• Subjected to high-concentrations of particulate such as fly ash or sand.
• Subjected to hot radiography conditions.
• Subjected to salt-water conditions, caustic or acidic materials.
• Subjected to accidental drops or falling objects.
• Whenever subjected to extreme environmental conditions.
The routine maintenance performed every 3 months requires partial disassembly, cleaning, inspection,
re-lubrication and operational checks of the system. The complete maintenance (performed once a year)
involves a complete disassembly, cleaning, inspection, re-lubrication and operational tests of the entire
system.
Trained and qualified individuals within the licensee’s organization can perform equipment maintenance.
QSA Global, Inc. service engineers are available to provide maintenance on the systems at the licensee's
premises or at one of the service centers.
