SECTION 252:410-13-4. Operating requirements

Latest version.

(a)   Written procedures. Procedures shall be written in accordance with 252:410-3-32(a).
(b)   Bypassing. No individual shall bypass a safety device or interlock unless such individual has obtained the approval of the radiation safety officer. Such approval shall be for a specified period of time. When a safety device or interlock has been bypassed, a readily discernible sign bearing the words "SAFETY DEVICE NOT WORKING" or words having similar intent shall be placed on the radiation source housing.
(c)   Repair or modification of x-ray tube systems. No operation involving removal of covers, shielding materials, or tube housings or modifications to shutters, collimators, or beam stops shall be performed without verifying the tube is off and will remain off until safe conditions have been restored. The main switch, rather than interlocks, shall be used for routine shutdown in preparation for repairs.
