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. DHS 157.27(3)(a)5.5. Prior to initial fitting of respirators, and at least every 12 months thereafter, a physician shall determine that the individual user is physically able to use the respiratory protection equipment. DHS 157.27(3)(a)6.6. Fit testing, with a fit factor >/= 10 times the assigned protection factor for negative pressure devices, and a fit factor >/= 500 for any positive pressure, continuous flow, and pressure-demand devices, before the first field use of tight fitting, face-sealing respirators and periodically thereafter at a frequency not to exceed one year. Fit testing shall be performed with the facepiece operating in the negative pressure mode. DHS 157.27(3)(b)(b) A licensee shall advise each respirator user that the user may leave the area at any time for relief from respirator use in the event of equipment malfunction, physical or psychological distress, procedural or communication failure, significant deterioration of operating conditions, or any other conditions that might require such relief. DHS 157.27(3)(c)(c) A licensee shall also consider limitations appropriate to the type and mode of use. When selecting respiratory devices the licensee shall provide for vision correction, adequate communication, low temperature work environments, and the concurrent use of other safety or radiological protection equipment. The licensee shall use equipment in such a way as not to interfere with the proper operation of the respirator. DHS 157.27(3)(d)(d) Standby rescue persons are required whenever one-piece atmosphere-supplying suits, or any combination of supplied air respiratory protection device and personnel protective equipment are used from which an unaided individual would have difficulty extricating himself or herself. The standby persons shall be equipped with respiratory protection devices or other apparatus appropriate for the potential hazards. The standby rescue persons shall observe or otherwise maintain continuous communication with the workers via visual, voice, signal line, telephone, radio, or other suitable means, and be immediately available to assist them in case of a failure of the air supply or for any other reason that requires relief from distress. A sufficient number of standby rescue persons shall be immediately available to assist all users of this type of equipment and to provide effective emergency rescue if needed. DHS 157.27 NoteNote: Examples of means of continuous communication are visual, voice, signal line, telephone, radio or other suitable means.
