 when paused
Immediately perform the following procedure:
1. Press the emergency stop button in the TCR.
Note: The emergency stop button can be a global or local emergency stop,
depending on the configuration of your PT center.
2. Turn the TCR master key switch off.
3. Open the doors of the TR.
If this procedure fails to stop the irradiation, contact the MCR immediately and
request the accelerator operator to shut off the RF.
The TR must not be used for treatments until the cause of the incident has been fully
established and remedied.
The irradiation should only be resumed after the cause of the incident has been fully
investigated and remedied.
Staff are Present in a Secured Area
Beam should only be On when the securable areas (i.e., all locations where
irradiation hazards are present: cyclotron vault, beam transportation vault, GTR pit,
TRs and technical rooms adjacent to TRs) have been properly searched and secured.
The securable areas are listed in Appendix D “Emergency Stop Button Locations”.
This is applicable to all securable areas required for sending beam to a given TR.
Note: The MCR and TCRs are not securable areas.
Important In any case, immediately contact the local radiation safety department
and inform them with full details of the radiation incident.
WARNING Closure of a door of a securable area is part of a search procedure.
Whenever you close a door of a securable area, make sure that no other
person is performing the search procedure for the same securable area.
