DHS 157.26(2)(b)(b) A licensee or registrant is not required to control entrance or access to rooms or other areas containing sources of radiation capable of producing a very high radiation area as described in par. (a) if the licensee or registrant has met all the specific requirements for access and control specified in other applicable parts of this chapter, such as subch. IV for industrial radiography and subch. VIII for x-rays in the healing arts and accelerators. DHS 157.26 HistoryHistory: CR 01-108: cr. Register July 2002 No. 559, eff. 8-1-02. DHS 157.27DHS 157.27 Respiratory protection and controls to restrict internal exposure in restricted areas. DHS 157.27(1)(1) Use of process or other engineering controls. A licensee or registrant shall use, to the extent practical, process or other engineering controls, such as containment, decontamination or ventilation, to control the concentrations of radioactive material in air. DHS 157.27(2)(a)(a) When it is not practical to apply process or other engineering controls to control the concentrations of radioactive material in air to values below those that define an airborne radioactivity area, a licensee or registrant shall increase monitoring and limit intakes by one or more of the following means: DHS 157.27(2)(b)(b) If a licensee or registrant performs an ALARA analysis to determine whether or not respirators should be used, a licensee or registrant may also consider the impact of respirator use on workers’ industrial health and safety. DHS 157.27(3)(3) Use of individual respiratory protection equipment. DHS 157.27(3)(a)(a) If a licensee or registrant uses respiratory protection equipment to limit intakes under sub. (2), all of the following criteria shall apply: DHS 157.27(3)(a)1.1. Except as provided in subd. 2., a licensee or registrant shall use only respiratory protection equipment that is tested and certified by the U.S. national institute for occupational safety and health. DHS 157.27(3)(a)2.2. A licensee or registrant may use equipment that has not been tested or certified by the U.S. national institute for occupational safety or for which there is no schedule for testing or certification, provided the licensee or registrant has submitted to the department and the department has approved a request for authorized use of that equipment. The request shall include documentation of a demonstration by testing, or a demonstration on the basis of test information, that the material and performance characteristics of the equipment are capable of providing the proposed degree of protection under anticipated conditions of use. DHS 157.27(3)(a)3.3. A licensee or registrant shall implement and maintain a respiratory protection program that includes all of the following: DHS 157.27(3)(a)3.a.a. Air sampling sufficient to identify the potential hazard, permit proper equipment selection and estimate doses. DHS 157.27(3)(a)4.4. A licensee or registrant shall have written procedures regarding all of the following: DHS 157.27(3)(a)4.g.g. Storage, issuance, maintenance, repair, testing and quality assurance of respiratory protection equipment.
