DHS 157.87(7)(f) (f) Vehicle limitations.

DHS 157.87(7)(f)1. 1. When the procedures for operation of a mobile or fixed radiation generating device used for security screening of vehicles includes knowingly exposing human occupants to the primary beam when screening vehicles, structures or containers, the system shall be subject to the same requirements as general-use or limited-use systems as provided in pars. (a) to (e).

DHS 157.87(7)(f)2. 2. If the requirements in pars. (a) to (e) cannot be met, and if vehicle occupants are knowingly exposed to the primary beam of a security screening system, then there shall be means to assure the occupied portion of the vehicle is outside of the scan area while the primary beam is emitted, or procedures shall be established and implemented to assure that no occupants are present in the vehicle during screening.

DHS 157.87(7)(f)3. 3. The effective dose to an individual for a single inadvertent exposure to the primary beam shall not exceed one mSv (100 mrem). The reliability of the procedure used to assure that there are no occupants of a vehicle to be scanned shall be commensurate with the potential severity of an inadvertent exposure. If the one mSv (100 mrem) limit cannot be assured, a pre-screening with a mode or system which may meet the limits in pars. (c) to (e) shall be used to verify there are no occupants in the vehicle being examined.

DHS 157.87(8) (8) Application for exemptions. Any radiation generating device user or manufacturer that cannot meet the applicable requirements of this subchapter may submit to the department a request for an exemption to the specific requirement in question. The exemption request shall demonstrate to the department all of the following:

DHS 157.87(8)(a) (a) That the use of the radiation generating device will not result in undue hazard to public health and safety or property.

DHS 157.87(8)(b) (b) That compliance would require replacement or substantial modification of the radiation generating device.

DHS 157.87(8)(c) (c) That the registrant will achieve, through other means, radiation protection equivalent to that required by the regulation.

DHS 157.87(8)(d) (d) Why the regulatory standard or requirement could not be met.

DHS 157.89(2) (2) Presence of representatives of licensee or registrant during inspection.

DHS 157.89(2)(a) (a) A licensee, registrant or designee may accompany department inspectors during an inspection.

DHS 157.89(2)(b) (b) If, at the time of inspection, an individual has been authorized by the workers to represent them during department inspections, a licensee or registrant shall notify the inspectors of that authorization and shall permit the workers’ representative to accompany the inspectors during the inspection of physical working conditions.

DHS 157.89(2)(c) (c) Each workers’ representative shall be routinely engaged in work under control of the licensee or registrant and shall have received instructions as specified in s. DHS 157.88 (2).

DHS 157.89(2)(d) (d) Different representatives of a licensee or registrant or workers may accompany the department’s inspectors during different phases of an inspection if there is no interference with the conduct of the inspection, but only one workers’ representative at a time may accompany the inspectors.

DHS 157.89(2)(e) (e) With the approval of a licensee or registrant and the workers’ representative, an individual who is not routinely engaged in work under control of the licensee or registrant, such as a consultant to the licensee or registrant or to the workers’ representative, may accompany department inspectors during the inspection of physical working conditions.

DHS 157.89(2)(f) (f) Department inspectors may refuse to permit any individual who deliberately interferes with a fair and orderly inspection to accompany them on the inspection. An individual may accompany an inspector in areas containing information classified by an agency of the U.S. government in the interest of national security only if the individual is authorized to do so by the licensee or registrant. The workers’ representative may enter an area containing proprietary information only if the representative has been previously authorized by the licensee or registrant to enter that area.
