25 Pa. Code § 227.13a. Operating requirements.

§ 227.13a. Operating requirements.

 (a)  Operating procedures shall be written and available to the analytical X-ray equipment operators. These procedures shall include instructions for sample insertion and manipulation, equipment alignment, routine maintenance and data recording procedures which are related to radiation safety. An individual may not operate analytical X-ray equipment in a manner other than that specified in the operating procedures unless the individual has obtained written approval from the radiation safety officer.

 (b)  An individual may not bypass or otherwise circumvent a safety device unless the individual has obtained the prior written approval of the radiation safety officer. The radiation safety officer may grant the permission only if the following conditions are met:

   (1)  The radiation safety officer establishes administrative controls and procedures to assure the radiation safety of individuals working around the system.

   (2)  The period for the bypass of the safety device is not more than 30 days unless written permission is obtained from the Department for a longer period.

   (3)  A readily discernible sign bearing the words ‘‘SAFETY DEVICE NOT WORKING,’’ or words containing a similar warning, is placed on the radiation source housing.

 (c)  Except as specified in subsection (b), an operation involving removal of covers, shielding materials or tube housings or modifications to shutters, collimators or beam stops may not be performed without ascertaining that 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.

 (d)  Emergency procedures shall be written and posted near the equipment and shall list the names and telephone numbers of personnel to contact. The emergency procedures shall also provide information necessary to de-energize the equipment, such as location and operation of the power supply or circuit breakers.
