Ohio Administrative Code › Title 3701:1 - Radiation Control › Chapter 3701:1-68 - Industrial Radiation Equipment › Section 3701:1-68-06 - Non-medical cabinet systems

Current through all regulations passed and filed through July 1, 2024
In addition to the applicable rules in this chapter and Chapter
				3701:1-38 of the Administrative Code, handlers of cabinet systems
				will
				comply with the following:
(A) All
			 cabinet system will meet the following equipment standards:
(1) Radiation emitted from a cabinet system
			 will not
			 exceed an exposure of 4.4 microgray (0.5 milliroentgen) in one hour at any
			 point five centimeters outside the external surface.
(2) Cabinet systems provided with at least
			 one port will be designed such that the insertion of any part
			 of the human body through any port into the primary beam
			 will not
			 be possible.
(3) Cabinet systems
			 provided with at least one aperture will be designed
			 such that the insertion of any part of the human body through any aperture
			 will 
			 not be possible.
(4) Safety
			 Interlocks:
(a) Each door
			 will
			 have a minimum of two safety interlocks. One, but not both of the
			 obligated interlocks will be such
			 that door opening results in physical disconnection of the energy supply
			 circuit to the high-voltage generator, and such disconnection
			 will not
			 be dependent upon any moving part other than the door;
(b) Each access panel
			 will
			 have at least one safety interlock;
(c) Following interruption of x-ray
			 generation by the functioning of any safety interlock, use of a control
			 provided in accordance with paragraph (A)(6)(b) of this rule
			 will be
			 necessary for resumption of x-ray generation; and
(d) Failure of any single part of the
			 enclosed fail-safe system will not cause failure of more than one
			 obligated safety interlock.
(5) A ground fault will not result
			 in the generation of x-rays.
(6)
			 Controls and indicators will provide:
(a) A
			 key-actuated control to ensure that x-ray generation is not possible with the
			 key removed;
(b) A control or
			 controls to initiate and terminate the generation of x-rays other than by
			 functioning of a safety interlock or the main power control;
(c) Two independent means which indicate when
			 and only when x-rays are being generated, unless the x-ray generation period is
			 less than one-half second, in which case the indicators
			 will be
			 activated for one-half second, and which are discernible from any point at
			 which initiation of x-ray generation is possible. Failure of a single part of
			 the cabinet system will not cause failure of both indicators to perform
			 their intended function. One, but not both, of the indicators
			 obligated by this paragraph may be a milliammeter
			 labeled to indicate x-ray tube current. All other indicators
			 will be
			 legibly labeled "X-RAY ON";
(d)
			 Additional means other than milliammeters which indicate when and only when
			 x-rays are being generated, unless the x-ray generation period is less than
			 one-half second in which case the indicators will be
			 activated for one-half second, as needed to insure that at least one indicator
			 is visible from each door, access panel, and port, and is legibly labeled
			 "X-RAY ON"; and
(e) Warning labels:
(i) There will be
			 permanently affixed or inscribed on the cabinet x-ray system at the location of
			 any controls which can be used to initiate x-ray generation, a clearly legible
			 and visible label bearing the statement: "CAUTION: X-RAYS PRODUCED WHEN
			 ENERGIZED."
(ii) There
			 will be
			 permanently affixed or inscribed on the cabinet x-ray system adjacent to each
			 port a clearly legible and visible label bearing the statement: "CAUTION: DO
			 NOT INSERT ANY PART OF THE BODY WHEN SYSTEM IS ENERGIZED - X-RAY
			 HAZARD."
