Model 880 Delta, Model 880 Sigma and Model 880 Elite safety class A components
Safety Class A designation items

Items that comprise the Model 880 Delta, Sigma or Elite radiographic exposure device and

associated equipment that are critical for safe radiological operation are classified as Class A

items or components. Class A items can be structures, components and systems whose

failure or function could directly result in a condition adversely affecting public health and

safety. This would include extreme conditions such as the loss of primary containment with a

subsequent release of radioactive material and or a loss of shielding creating a substantial

safety hazard. Replacement parts that are sent to you with a safety Class A designation are

clearly marked with lot numbers and contain instructions to maintain traceability.

Considerations of Safety Class A items

Users of the Model 880 Delta, Sigma and Elite exposure device 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:

G

maintaining traceability of Class A replacement items or components to a specific

exposure device or an associated component.

G

use of manufacturer specified items to maintain the integrity of the exposure

device/transport package according to the certifications. Do not use generic grade

items or components that do not meet original design specifications.

G

performance of periodic inspections to verify the Class A items are not excessively worn

from long term use or have been damaged from accidents.

G

use and handling of the system consistent with it's design and intended application.

G

promptly notifying 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.
