DHS 157.27(3)(f) (f) A licensee or registrant shall ensure that no objects, materials or substances, such as facial hair, or any conditions that interfere with the face to facepiece seal or valve function, and that are under the control of the respirator wearer, are present between the skin of the wearer's face and the sealing surface of a tight-fitting respirator facepiece.
DHS 157.27(3)(g) (g) In estimating the dose to individuals from intake of airborne radioactive materials, the concentration of radioactive material in the air that is inhaled when respirators are worn is initially assumed to be the ambient concentration in air without respiratory protection, divided by the assigned protection factor. If the dose is later found to be greater than the estimated dose, the corrected value must be used. If the dose is later found to be less than the estimated dose, the corrected value may be used.
DHS 157.27(4) (4)Application for use of higher assigned protection factors.
DHS 157.27(4)(a)(a) A licensee or registrant shall obtain authorization from the department before using assigned protection factors in excess of those specified in ch. DHS 157 Appendix D.
DHS 157.27(4)(b) (b) The department may authorize a licensee or registrant to use higher assigned protection factors on receipt of an application that meets the following criteria:
DHS 157.27(4)(b)1. 1. Describes the situation for which a need exists for higher protection factors.
DHS 157.27(4)(b)2. 2. Demonstrates that the respiratory protection equipment provides these higher protection factors under the proposed conditions of use.
