It is the purpose of the Respiratory Protection document to reduce employee exposure to occupational dusts, fogs, fumes, mists, radionuclides, smokes, sprays, gases, biological agents and vapors. This shall be accomplished as far as feasible by accepted engineering control measures. When such controls are not feasible, or while they are being implemented, appropriate respiratory protection shall be used in accordance with this chapter. In these situations, a Respiratory Protection Program that includes training, fit testing and medical evaluations is provided.



This chapter applies to all workers, contractors, users, vendors, and visitors who may be exposed to respiratory hazards requiring the use of respiratory protection as a feasible control method. While the South Dakota Science and Technology Authority (SDSTA) respiratory protection program is administered to SDSTA employees only, all exposed users and contractors are expected to be covered by a similar program where respiratory protection use is required.

All oxygen-deficient atmospheres (less than 19.5% O2 by volume) shall be considered IDLH.

Loose-fitting facepiece: respiratory inlet covering that is designed to form a partial seal with the face.

Negative pressure respirator (tight fitting): A respirator in which the air pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator.

Occupational Exposure Limit (OEL): An upper limit on the acceptable concentration of a hazardous substance in workplace air for a particular material or class of materials. It is typically set by a consensus standard organization of experts in order to protect occupational safety and health.

Oxygen deficient atmosphere: An atmosphere with oxygen content below 19.5% by volume.

Physician or other licensed health care professional (PLHCP): An individual whose legally permitted scope of practice (i.e., license, registration, or certification) allows him or her to independently provide, or be delegated the responsibility to provide, some or all of the health care services required by paragraph (e) 29 CFR 1910.134.

Positive pressure respirator: A respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator.

5.1 Work Area Evaluations

     5.1.1. The employer will evaluate respiratory hazard(s) in the workplace, identify relevant workplace and user factors,and base respirator selection on these factors. Exposure evaluations will be performed initially and on a periodic basis to assess the presence of respiratory hazards and to aid in proper respirator selection. In order to determine exposure level, exposure evaluations will be determined by:‌

  • air samples of the workplace representative for the work shift;
  • exposure assessment based on analogous processes; or
  • judgement based on professional expertise.

Personal sampling equipment may be used in accordance with accepted industrial hygiene practice or standards to sample each work area. Results of these samples will pinpoint areas where respiratory protection is required.

   5.1.2.    The exposure assessment will be performed prior to commencing any routine or non- routine task requiring respiratory protection. Periodically thereafter as required by changing conditions, regulatory substance-specific standards or every 12 months, a review of the exposure assessment will be made to determine if respiratory protection continues to be required. If respiratory protection is still necessary, the previously chosen respirators will be reviewed to assure that they still provide adequate protection.

  5.1.3.     Records of all exposure assessments will be maintained by the ESH Department.

5.2 Respirator Selection

5.2.1 Sanford Underground Research Facility (SURF) will select only respirators that are certified by the National Institute for Occupational Safety and Health (NIOSH) which must be used in compliance with the conditions of its certification. The selection will be based upon the physical and chemical properties of the air contaminants and the concentration level likely to be encountered by the employee. The respirator program administrator will make a respirator available immediately to each employee who is placed as a new hire or a transferee to a job that requires respiratory protection. Replacement respirators/cartridges and filters will be made available as required. Where exposure cannot be identified or reasonably estimated, the atmosphere shall be considered immediately dangerous to life or health (IDLH).

5.2.2 Selection of all respirators will conform to the Occupational Safety and Health Administration (OSHA) Assigned Protection Factors (APF) Table (see Table 1: Assigned Protection Factors) when sampling data are available upon respirator selection or becomes available while the task is being performed.

                                                           Table 1.0—Assigned Protection Factors5

Notes: 1Employers may select respirators assigned for use in higher workplace concentrations of a hazardous substance for use at lower concentrations of that substance, or when required respirator use is independent of concentration. 

2The assigned protection factors in Table 1 are only effective when the employer implements a continuing, effective respirator program as required by this section (29 CFR 1910.134), including training, fit testing, maintenance, and use requirements. 

3This APF category includes filtering facepieces, and half masks with elastomeric facepieces. 

4The employer must have evidence provided by the respirator manufacturer that testing of these respirators demonstrates performance at a level of protection of 1,000 or greater to receive an APF of 1,000. This level of performance can best be demonstrated by performing a WPF or SWPF study or equivalent testing. Absent such testing, all other PAPRs and SARs with helmets/hoods are to be treated as loose-fitting facepiece respirators, and receive an APF of 25. 

5These APFs do not apply to respirators used solely for escape. For escape respirators used in association with specific substances covered by 29 CFR 1910 subpart Z, employers must refer to the appropriate substance-specific standards in that subpart. Escape respirators for other IDLH atmospheres are specified by 29 CFR 1910.134 (d)(2)(ii). 

5.3 Respirators for IDLH atmospheres

5.3.1. Approved respirators:

  • Full facepiece pressure demand self-contained breathing apparatus (SCBA) certified by NIOSH for a minimum service life of thirty minutes, or
  • Combination full facepiece pressure demand supplied-air respirator (SAR) with auxiliary self-contained air supply.

5.3.2 SURF shall ensure that compressed air, compressed oxygen, liquid air, and liquid oxygen used for respirator usage (with the exception of the compressed air in the Refuge Chamber) comply with the following specifications:

  • Compressed and liquid oxygen shall meet the United States Pharmacopoeia requirements for medical or breathing oxygen; and
  • Compressed breathing air shall meet at least the requirements for Grade D breathing air described in ANSI/Compressed Gas Association Commodity Specification for Air, G-7.1- 1989, to include:
    • Oxygen content (v/v) of 19.5-23.5%;
    • Hydrocarbon (condensed) content of 5 milligrams per cubic meter of air or less;
    • Carbon monoxide (CO) content of 10 parts per million (ppm) or less;
    • Carbon dioxide (CO2) content of 1,000 ppm or less; and
    • Lack of noticeable odor.
  • Only the respirator manufacturer's NIOSH-approved breathing-gas containers, marked and maintained in accordance with the Quality Assurance provisions of the NIOSH approval for the SCBA as issued in accordance with the NIOSH respirator-certification standard at 42 CFR part 84 will be used.
  • Cylinders used to supply breathing air to respirators must meet the following requirements:
    • Cylinders are tested and maintained as prescribed in the Shipping Container Specification Regulations of the Department of Transportation (49 CFR part 180);
    • Cylinders of purchased breathing air have a certificate of analysis from the supplier that the breathing air meets the requirements for Grade D breathing air; and
    • The moisture content in the cylinder does not exceed a dew point of -50 degrees Fahrenheit (-45.6 degrees Celsius) at 1 atmosphere pressure.

5.4 Respirators for non-IDLH atmospheres

5.4.1 For protection against vapors and gases, the employer shall provide:

  • An atmosphere-supplying respirator, or
  • An air-purifying respirator, provided that:
    • Respirator is equipped with an end-of-service-life indicator (ESLI) certified by NIOSH (with a legible label) for the contaminants, or
    • if there is no ESLI appropriate for conditions of employer’s workplace, the employer implements a change schedule for canisters and cartridges that will ensure that they are changed before the end of their service life and describes in the respirator program the information and data relied upon and basis for the change schedule and reliance on the data.

5.4.2 For protection against particulates, the employer shall provide:

  • Atmosphere-supplying respirator; or
  • An air-purifying respirator equipped with HEPA filters certified by NIOSH (with a legible label) or with filters certified for particulates under 42 CFR Part 84; or
  • An air-purifying respirator equipped with any filter certified for particulates by NIOSH (with a legible label) for contaminants consisting primarily of particulates with mass median aerodynamic diameters of at least 2 micrometers.

5.5 Escape-Only Respirators

Escape-only respirators are required to be within 25 feet (ft) proximity of any person who enters the underground. The two types of escape-only respirators available at SURF are the MSA W65 self-rescuer and the Drager Oxy K self-rescuer. Underground personnel are to be trained on the inspection and use of each type of respirator used. A Drager Oxy K self-rescuer must be used as an escape-only respirator when oxygen deficient atmospheres (such as proximity to cryogenic equipment) could be present. The ESH Department will serve as resource for proper inspection, use, and maintenance of escape-only respirators. Escape-only respirators do not require a medical evaluation.


6.1. Each employee who is being considered for inclusion in the Respiratory Protection Program will participate in a medical evaluation. A determination will be made initially upon employment or change into a job classification requiring respiratory protection and every 24- months thereafter. Additional medical evaluations are required under certain circumstances, e.g.:

  • Employee reports medical signs or symptoms related to an inability to use respirator;
  • Physician or other licensed health care professional (PLHCP), program administrator, or supervisor recommends reevaluation;
  • Information from the respirator program, including observations made during fit testing and program evaluation, indicates a need; or
  • Change occurs in workplace conditions that may substantially increase the physiological burden on an employee.

6.2. The employee will fill out the Medical Questionnaire which will be reviewed by the PLHCP or undergo an initial medical examination that obtains the same information as the medical questionnaire. A follow-up medical examination will be provided for an employee who gives a positive response to any questions 1 through 7 in Section 2, Part A of the Medical Questionnaire or whose initial medical examination demonstrates the need for a follow-up medical examination. The follow-up medical examination will include any medical tests, consultations or diagnostic procedures that the PLHCP deems necessary to make a final determination.

6.3. The medical questionnaire and examinations will be administered confidentially during the employee’s normal working hours or at a time and place convenient to the employee. The questionnaire will be returned to the PLHCP after it has been completed. The employee may discuss the questionnaire and examination results with the PLHCP.

6.4. The purpose of the questionnaire and the initial and follow-up examinations is to determine that the employee is physically able to perform their work while wearing respiratory protective equipment. If the PLHCP denies approval, the employee will not be able to participate in the Respiratory Protection Program.

6.5.  Copies of the medical evaluation and questionnaire will be kept in the employee’s personnel file in accordance with 29 CFR 1926.33. Copies of the Request for Medical Clearance for each respirator wearer will be available on file at the Administration Building.

  • The Medical Questionnaire form can be found in Appendix A of this program.
  • The Request for Medical Clearance form can be found in Appendix B of this program.


7.1. Training

7.1.1. Workers, upon assignment to an area requiring respirators, will be instructed by their supervisors relative to their responsibilities in the respiratory program. They will also be instructed in the need, use, limitations, and care of their respirator. The ESH Department is available to assist, monitor, and provide resources for this training.

7.1.2. Refresher training will be provided at least every 12 months after initial training and/or when changes in the workplace or the type of respirator make the previous training obsolete, inadequacies in the employee’s knowledge or use of the respirator indicate that the employee has not retained the requisite understanding or skill, or any other situation arises in which retraining appears necessary to ensure safe respirator use. Records of all training provided to each individual will be maintained by the ESH Department.

7.2 Fit Testing

7.2.1. Employees who use tight fitting respirators will be properly fitted and tested for a face seal prior to use of the respirator. This will be accomplished by following the fit test procedures outlined in this program (see Appendix C: Fit Test Procedures). Quantitative fit testing is the preferred method for fit testing of full-face respirators used in the negative pressure mode for protection greater than 10 times the exposure limit but not to exceed 50 times the exposure limit. Qualitative fit testing may only be used to fit test negative pressure air-purifying respirators that must achieve a fit factor of 100 or less.

7.2.2. Fit testing will be performed initially upon employee assignment to an area where respirators are required. All tight-fitting respirator models (negative and positive) that will used will be fit tested for each individual. Positive pressure tight fitting respirators will be fit tested in the negative pressure mode.

7.2.3. Additional fit tests will be conducted whenever the employee reports, or the PLHCP, supervisor, or program administrator makes visual observations of changes in the employee’s physical condition that could affect respirator fit. Such conditions include, but are not limited to, facial scaring, dental changes, cosmetic surgery, or an obvious change in body weight.

7.2.4. If, after passing a fit test, the employee subsequently notifies management (e.g., supervisor, program administrator, or PLHCP) that the fit of the respirator is unacceptable, the employee will be given a reasonable opportunity to select a different respirator facepiece and to be retested.

  • Individual fit testing records (See Appendix F: Respirator Fit Test Training and Education Form) will be kept for each employee tested at SURF until the next fit test is performed.

7.2.5. Fit testing of employees with any hair growth such as stubble beard growth, beard or long sideburns that extends under the face seal or interferes with valve function is prohibited.


8.1. Facepiece seal protection

8.2.1 Facial hair or any other condition that prevents direct contact between the face and the edge of the respirator will not be permitted with tight fitting half or full facepiece (negative or positive pressure) or loose fitting facepieces. Eyeglasses, goggles, and other personal protective equipment will be worn in a manner that does not interfere with the respirator sealing surface.

8.1.2. Facial hair or any other condition that interferes with the seal of the respirator facepiece to include the function of exhalation or inhalation valves will not be permitted.

8.1.3.All respirator users of tight fitting facepieces will perform a user seal check each time they put on the respirator. Methods for performing the user seal checks will be covered in Appendix D: User Seal Check Procedures.

8.2 Continuing respirator effectiveness

8.2.1. Supervisors will maintain ongoing surveillance of employee exposure or stress. If conditions change such that respirator effectiveness may be affected, the respirator selection will be re-evaluated.

8.2.2. Employees shall leave a work area requiring respirator use under the following conditions:

  1. To wash face and facepiece as necessary to prevent skin or eye irritation.
  2. Detection of vapor or gas breakthrough, changes in breathing resistance, or facepiece leakage.
  3. To replace the respirator, filter, cartridge, or canister.
  4. Upon malfunction of the respirator.
  5. If severe discomfort in wearing the respirator is detected.
  6. Illness of the respirator wearer, including sensation of dizziness, nausea, weakness, breathing difficulty, coughing, sneezing, vomiting, fever or chills.
  • If an employee leaves the work area for any of the above reasons, they will not re-enter until the specific problem has been identified and corrected.

8.3 Procedures for IDLH atmospheres

For all IDLH atmospheres, ensure that:

  • At least one employee is located outside the IDLH atmosphere.
  • Visual, voice, or signal line communication is maintained between the employee(s) in the IDLH atmosphere and the employee(s) located outside the IDLH atmosphere.
  • A trained rescue team is suitably equipped and located in a position to provide a rescue if needed.

8.4 Voluntary Use

Voluntary use of respirators shall be allowed only under the following conditions:

  1. SURF shall provide respiratory protection for employees who ask for it or let employees use their own respiratory protection, if such respirator use will not create a hazard.
  2. SURF shall provide voluntary respirator users with the information contained in Appendix G: Voluntary Use of Respirators (1910.134 App D Information for employees using respirators when not required under the standard).
  3. Fit testing is not mandatory for voluntary respirator use.

Voluntary use of filtering facepieces (also known as “dust masks”) is exempt from enrollment in the respiratory protection program.


Respirators will be properly maintained to retain their original effectiveness by periodic inspection, repair, cleaning and proper storage.

9.1. Inspection

The wearer of a respirator will inspect it daily whenever it is in use, prior to use and during cleaning. Respirators used for emergency response purposes shall be inspected and documented at least monthly by a competent person(s). Spot checks for personnel wearing respirators will be periodically performed by employee’s superviser or responsible person to ensure a suitable fit, usage, and condition of each respirator. The use of defective respirators will not be permitted. If a defective respirator is found during inspection, it will be taken out of service and discarded or repaired.

9.2. Repair

During cleaning and maintenance, respirators that do not pass inspection will be replaced or repaired immediately. Repair of the respirator will be done with parts designed for the respirator in accordance with the manufacturer’s instructions by an appropriately trained individual. No attempt will be made to replace components or make adjustments, modifications or repairs beyond the manufacturer’s recommendations.

9.3. Cleaning

Respirators not discarded after one shift use will be cleaned on a daily basis (or after each use if not used daily) according to the manufacturer’s instructions by the assigned employee or other person designated by the Respiratory Protection Program Administrator. Facilities and supplies for cleaning these respirators will be made available. The respirator cleaning procedure is outlined in Appendix E: Respirator Cleaning Procedures.

9.4. Storage

Respirators not discarded after one shift use will be stored in a suitable container away from areas of contamination and according to manufacturer’s instructions. The respirators will be stored in a location where they are protected from sunlight, dust, heat, cold, moisture, and damaging chemicals and they will be stored in a manner to prevent deformation of the facepiece, exhalation valve, and/or head strap (per manufacturer recommendations). Whenever feasible, respirators not discarded after one shift use will be marked and stored in such a manner to assure that they are worn only by the assigned employee.


10.1. Program Administration

10.1.1 The ESH Department has the responsibility for the administration of the respiratory protection program. A respiratory protection program administrator (RPA) will be appointed to act on any and all matters relating to the operation and administration of the respiratory protection program. All employees will cooperate to the fullest extent. The RPA is responsible for ensuring that:

  • Exposure assessments and monitoring of the respiratory hazards are conducted.
  • Worksite-specific procedures for this program are developed.
  • All associated records are maintained.
  • All program audits are conducted.

10.1.2. The following physician or licensed health care professional (PLHCP) providers are used for the medical evaluation of each employee who will wear a respirator:

#1 Designated PLHCP:

  • Medical Facility: Onsite Occupational Health Nurse
  • Address: 630 E. Summit St, Lead South Dakota

#2 Designated PLHCP:

  • Medical Facility: Black Hills Occupational Medicine
  • Address: 1161 Deadwood Ave, Rapid City South Dakota

10.1.3. SURF is responsible for determining the content and evaluating the results of all required respirator medical evaluations for this program.

10.1.4. SURF may elect to employ an outside agency for additional help in contaminant identification and measurement, including technical support, air sampling, and laboratory analysis. If any additional environmental safety and health plans are written for the project, they will be included as an attachment to this program for the designated project.

10.2 Program Evaluation

This program will be periodically reviewed and evaluated. The program will be audited by using the procedures outlined in this plan. The evaluations of the workplace will be carried out to ensure that the current written program is effectively implemented. They will include regular consultations with employees using respirators to assess their view on program effectiveness and to identify any problems. Factors to be assessed include respirator fit (including the ability to use the respirator without interfering with effective workplace performance), appropriate respirator selection for the hazards to which the employee is exposed, proper respirator use under workplace conditions the employee encounters, and proper respirator maintenance. These factors are included in the Program Evaluation process.
