(a) The requirements of this section are in addition to and not in substitution for the applicable requirements in N.J.A.C. 7:28.
(b) No person shall operate or permit the operation of a medical cabinet x-ray system used in the healing arts unless it meets the following requirements:
1. The registrant shall ensure and document that the operator has received a copy of the operator's manual, has been trained in the operating procedures for the system, and has demonstrated competence in operating the system to the registrant. This documentation shall be available to the department for review during any inspection. The registrant shall maintain a copy of the operator's manual in the proximity of the system;
2. Radiation emitted from the medical cabinet x-ray system shall not exceed an exposure of 0.5 milliroentgens in one hour at any point five centimeters outside the external surface;
3. No medical cabinet x-ray system shall be placed into operation until the registrant demonstrates that a qualified individual for the performance of radiation surveys for diagnostic x-ray equipment has determined that the exposure level in (b)2 above is not exceeded. Where an operating system is subsequently modified, repaired, or moved to a new location, the unit shall not be used until a qualified individual for the performance of radiation surveys for diagnostic x-ray equipment has determined compliance with this limit. The registrant shall maintain the original report(s) at the facility, and make the report(s) available to the Department during any inspection. The registrant shall submit a copy of the report(s) to the Department within 30 days of the date the determination has been completed;
4. Safety interlocks shall be provided on medical cabinet x-ray systems as follows:
i. Each door of a cabinet x-ray system shall have a minimum of two safety interlocks installed in such a manner that the opening of any door would disconnect the energy supply circuit to the high-voltage generator;
ii. Each access panel on a cabinet x-ray system shall have at least one safety interlock;
iii. Following interruption of the energy supply circuit by the functioning of any safety interlock, a manually reset control switch shall be activated before x-ray production can resume;
iv. Failure of any single component of the medical cabinet x-ray system shall not cause failure of more than one required safety interlock;
v. Safety interlocks shall be tested for operation at intervals not to exceed six months. A record of these tests shall be maintained for review by the Department during any inspection;
5. A medical cabinet x-ray system shall have a permanent floor, which means the underside external surface of the cabinet;
6. There shall be permanently affixed or inscribed on the medical cabinet x-ray system at the location of any controls which can be used to initiate x-ray production a clearly legible and visible label bearing the statement or words having a similar meaning: "CAUTION: X-RAYS PRODUCED WHEN ENERGIZED"; and
7. All medical cabinet systems shall be provided with the following controls and indicators:
i. A key-activated control to insure that x-ray production is not possible with the key removed;
ii. A control button or control switch to initiate and terminate the production of x-rays other than by the functioning of a safety interlock or the main power control;
iii. A warning light at the control button or control switch that indicates when and only when x-rays are being produced. This light shall be clearly labeled with the words: "X-RAY ON";
iv. A warning light which indicates when and only when x-rays are being produced. This warning light shall be visible from each door, access panel, and port, and shall be clearly labeled with the words: "X-RAY ON"; and
v. A means to indicate the kilovoltage, current and time during the production of x-rays at each x-ray control button or control switch unless the x-ray tube current is preset.
