Radiation Emitting Devices Regulations — 2
2 (1) A baggage inspection X-ray device shall be designed and constructed in such a way that it functions in accordance with the standards of functioning described in section 3 for as long as the device has its original components or has replacement components recommended by the manufacturer. (2) Notwithstanding subsection (1), a baggage inspection X-ray device shall have sufficient shielding to enable the device to comply with the standards of functioning described in section 3. (3) A baggage inspection X-ray device shall be designed and constructed to include the following safety features: (a) doors or panels over all access openings that are designed for insertion or removal of baggage, unless the device is designed to prevent the insertion of any part of the human body into the primary X-ray beam through those access openings; (b) interlocking of all doors or panels referred to in paragraph (a), with not less than two independent safety interlocks so that, if any of those doors or panels are opened, X-rays cannot be generated; (c) interlocking of all doors or panels that allow access to areas where the exposure to X-rays may exceed the level specified in section 3, except those doors or panels referred to in paragraph (a) so that, if any of those doors or panels are opened or removed, X-rays cannot be generated; (d) separate warning lights or other indicators (i) that clearly indicate to the operator when the device is powered and when X-rays are being generated, (ii) designed so that if a pulsed X-ray system is used, the X-rays “ON” lights or indicators remain on for at least 1/2 second, and (iii) that either (A) contain built-in duplication so that the requirements of subparagraphs (i) and (ii) are met, if one of the redundant components fails, or (B) are interlocked so that, if they malfunction, X-rays cannot be generated; (e) a lock that requires the insertion of a key before X-rays can be produced and that terminates the exposure when the key is removed; (f) subject to subsection 2(4), a control or controls to initiate the generation of X-rays, requiring separate operator action for each exposure; (g) the automatic alignment of the X-ray generator with the detector when the device is assembled; (h) an X-radiation warning sign described in section 4 that (i) is readily discernible and in clear view of the operator, and (ii) is permanently affixed to the device at all access openings where baggage is inserted or removed; (i) a permanent mark or label that is readily discernible and clearly visible on (i) the external surface of the device, under normal conditions of use, and (ii) on the external surface of the X-ray generator, under conditions of servicing, and that will identify the manufacturer, model designation, serial number, and date and place of manufacture of the device. (4) Paragraph (3)(f) does not apply to a baggage inspection X-ray device that contains a conveyor system if the X-ray exposure, or a sequence of X-ray exposures, is initiated automatically and the device (a) contains a photocell or other baggage sensing device that initiates X-ray exposures or a sequence of X-ray exposures automatically; and (b) is designed and constructed to include the following additional safety features: (i) a control or switch of a type that (A) requires continuous pressure by the operator to maintain the automatic operation of the device, and (B) stops the conveyor and terminates the X-ray exposure, or sequence of X-ray exposures, when released, and (ii) a conveyor of sufficient length to prevent insertion of any part of the human body into any area where the exposure to X-rays exceeds the level specified in section 3.
