Considerations of Safety Class A Items
Users of the SENTINEL SENTRY 330 and SENTINEL SENTRY 110 gamma-ray source projectors and
associated equipment must recognize their responsibilities of maintaining the integrity of the Type B(U)
package and the control of Safety Class A items and components by:
maintaining traceability of Class A replacement items or components to a specific gamma-ray source
projector or an associated component.
use of manufacturer specified items to maintain the integrity of the gamma-ray source
projector/transport package according to the certifications. Do not use generic grade items or
components that do not meet original design specifications.
performance of periodic inspections to verify the Class A items are not excessively worn from long
term use or have been damaged from accidents.
use and handling of the system consistent with its design and intended application.
promptly notify the manufacturer in the event a Safety Class A item or component which contains a
defect or deviates from the original design specifications. This action will initiate a formal evaluation of
the defect or deviation.
