Date of Adoption: June 3, 1998.
Purpose: This rule amends WAC 246-221-117, which in part sets the frequency at which a physician must determine that an individual is medically fit to use respiratory protection equipment in the nuclear industry. This rule allows the physician to determine the frequency of retesting consistent with federal requirements for the nuclear industry.

AMENDATORY SECTION (Amending WSR 94-01-073, filed 12/9/93, effective 1/9/94)
WAC 246-221-117 Use of individual respiratory protection equipment. (1) If the licensee uses respiratory protection equipment to limit intakes pursuant to WAC 246-221-113:
(a) The licensee shall use only respiratory protection equipment that is:
(i) Tested and certified or had certification extended by the National Institute for Occupational Safety and Health and the Mine Safety and Health Administration; or
(ii) Approved by the department on the basis of the licensee's submittal of an application for authorized use of other respiratory protection equipment, including a demonstration by testing, or a demonstration on the basis of reliable 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.
(b) The licensee shall implement and maintain a respiratory protection program that includes:
(i) Air sampling sufficient to identify the potential hazard, permit proper equipment selection, and estimate exposures; and
(ii) Surveys and bioassays, as appropriate, to evaluate actual intakes; and
(iii) Testing of respirators for operability immediately prior to each use; and
(iv) Written procedures regarding selection, fitting, issuance, maintenance, cleaning, repair, and testing of respirators, including testing for operability immediately prior to each use; supervision and training of personnel; monitoring, including air sampling and bioassays; and recordkeeping; and
(v) Determination by a physician prior to initial fitting of
respirators, and ((
at least)) either every twelve months
thereafter or periodically at a frequency determined by a
physician, that the individual user is (( physically able))
medically fit to use the respiratory protection equipment.
(c) The licensee shall issue a written policy statement on respirator usage covering:
(i) The use of process or other engineering controls, instead of respirators; and
(ii) The routine, nonroutine, and emergency use of respirators; and
(iii) The length of periods of respirator use and relief from respirator use.
(d) The 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.
(e) The licensee shall use equipment within the equipment manufacturer's expressed limitations for type and mode of use and shall provide proper visual, communication, and other special capabilities, such as adequate skin protection, when needed.
(2) When estimating exposure of individuals to airborne radioactive materials, the licensee may make allowance for respiratory protection equipment used to limit intakes pursuant to WAC 246-221-113, provided that the following conditions, in addition to those in subsection (1) of this section, are satisfied:
(a) The licensee selects respiratory protection equipment that provides a protection factor, specified in WAC 246-221-285, greater than the multiple by which peak concentrations of airborne radioactive materials in the working area are expected to exceed the values specified in WAC 246-221-290, Table I, Column 3. However, if the selection of respiratory protection equipment with a protection factor greater than the peak concentration is inconsistent with the goal specified in WAC 246-221-113 of keeping the total effective dose equivalent ALARA, the licensee may select respiratory protection equipment with a lower protection factor provided that such a selection would result in a total effective dose equivalent that is ALARA. The concentration of radioactive material in the air that is inhaled when respirators are worn may be initially estimated by dividing the average concentration in air, during each period of uninterrupted use, by the protection factor. If the exposure is later found to be greater than initially estimated, the corrected value shall be used; if the exposure is later found to be less than initially estimated, the corrected value may be used.
(b) The licensee shall obtain authorization from the department before assigning respiratory protection factors in excess of those specified in WAC 246-221-285. The department may authorize a licensee to use higher protection factors on receipt of an application that:
(i) Describes the situation for which a need exists for higher protection factors, and
(ii) Demonstrates that the respiratory protection equipment provides these higher protection factors under the proposed conditions of use.
(3) In an emergency, the licensee shall use as emergency equipment only respiratory protection equipment that has been specifically certified or had certification extended for emergency use by the National Institute for Occupational Safety and Health and the Mine Safety and Health Administration.
(4) Unless already authorized by license condition, the licensee shall notify the department in writing at least thirty days before the date that respiratory protection equipment is first used pursuant to either subsection (1) or (2) of this section.
