Section 180-8-005 - OPERATING REQUIREMENTSThis section addresses the operating requirements of radiation generating devices.
005.01PROCEDURES. Normal operating procedures must be written and available to all operators of radiation generating devices. No individual will be allowed to operate radiation generating devices in any manner other than that specified in the procedures unless the individual has obtained written approval of the radiation safety officer.005.02BYPASSING. No individual must bypass a safety device, interlock, or remove shielding unless the individual has obtained the approval of the radiation safety officer. The approval must be for a specified period of time. When a safety device or interlock has been bypassed, a visible sign bearing the words "SAFETY DEVICE NOT WORKING", or words having a similar intent, must be placed on the radiation source housing and at the control switch.005.03CONTROL PANEL. The radiation generating device can only be activated from a control panel. All indicators and controls that control the primary beam must be identifiable and visible through the use of labels, symbols, software displays, or the equivalent.005.04INTERLOCKS. An interlock must not be used to de-activate the x-ray tube or radiation generating device, except in an emergency or during testing of the interlock system. All interlocks must be of a fail-safe design.005.05MULTIPLE SOURCES. If more than one x-ray tube assembly or assemblies or focal spot can be operated sequentially or simultaneously from a control panel, visual indicators must identify which tube assembly or assemblies or focal spot has been selected. The selectors must be able to identify their function.005.06REPAIR OR MODIFICATION OF X-RAY TUBE SYSTEMS. Except as specified in subsection 005.02, no operation involving removal of covers, shielding materials, tube housing, modifications to shutters, collimators, or beam stops must be performed without determining that the tube is off and will remain off until safe conditions have been restored. The main switch, rather than interlocks, must be used for routine shutdown in preparation for repairs.180 Neb. Admin. Code, ch. 8, § 005
