General safety provisions

(a) Equipment. No person shall make, sell, lease, transfer, lend or install x-ray or fluoroscopic equipment or the supplies used in connection with such equipment unless such supplies and equipment, when properly placed in operation and properly used, will meet the requirements of sections 19-25d-3 to 19-25d-11, inclusive. This includes responsibilities for the delivery of cones or collimators, filters, adequate timers and fluoroscopic shutters, where applicable. (b) Use (1) The owner shall be responsible for assuring that all requirements of sections 19-25d-3 to 19-25d-11, inclusive, are met. (2) The owner shall assure that all x-ray equipment under his control is operated only by individuals adequately instructed in safe operating procedures and competent in safe use of the equipment. (c) Shielding (1) Each installation shall be provided with primary barriers and/or secondary barriers of such thickness as are computed in accordance with Appendix C, National Bureau of Standards Handbook 76: "Medical X-ray Protection Up to Three Million Volts," or any official revision of or subsequent replacement for this handbook, a copy of which is on file in the state department of environmental protection, state office building, Hartford. (2) Lead barriers shall be mounted in such a manner that they will not sag or cold-flow because of their own weight and shall be protected against mechanical damage. (3) Joints between different kinds of protective materials shall be so designed that the over-all protection of the barrier is not impaired. (4) Joints at the floor and ceiling shall be so designed that the over-all protection is not impaired. (5) Windows, window frames, doors and door frames shall have the same lead equivalent as that required of the adjacent wall. (6) Holes in protective barriers shall be covered so that overall attenuation is not impaired. (d) The commissioner may grant a variance to requirements in Sections 19-25d-3 to 19-25d-11 inclusive, provided that it can be demonstrated that the use of the equipment under the variance will not result in an increase in radiation exposure to the patient or operator.
