Yale University Respiratory Protection Program

1. Introduction

This document establishes Yale University’s written compliance program for respiratory protection, as required

by the Occupational Safety and Health Administration (OSHA) under Title 29 Code of Federal Regulations

Part 1910.134 (See Appendix A for a copy of the Standard). This Respiratory Protection Program addresses the

use of respiratory protection as a method to protect Yale University employees from exposures to airborne

biological, chemical, and physical agents to safe levels below exposure limits, as well as from oxygen deficient

atmospheres (i.e.<19.5% O

). Whenever feasible, engineering controls and work practice controls will first be

used to maintain worker exposures below exposure limits and at a safe level. It is understood that respiratory

protection shall only be required if these controls are not feasible or are not able to reduce exposures

adequately.

The Occupational Health and Safety Section in the Yale Environmental Health & Safety (EHS) office

administers the Respiratory Protection Program.

2. Responsibilities

Various Yale University departments and employees have responsibilities under this program, including:

a. Environmental Health & Safety - Respirator Program Administrator

• Preparing, reviewing, and periodically revising this program.

• Providing and/or overseeing respirator fit-testing and training, including training other designated employees

outside EHS to perform the respirator training and fit-testing.

• Monitoring and evaluating respirable hazards in the workplace.

• Providing guidance to supervisors in the selection and purchase of approved respirators.

• Maintaining records of exposure assessments, training, and respirator fit testing.

• Coordinating recordkeeping and notifications with the Employee Health Office.

b. Employee Health Office

• Developing and implementing a medical surveillance program for approved respirator users.

• Maintaining medical surveillance records.

c. Supervisors

• Providing new employees with informal on-the-job training about potential respirable hazards, personal

protective equipment requirements, and this Program.

• Notifying Yale Environmental Health & Safety and the Employee Health Office about workplace conditions

and potentially affected employees.

• Making information and training materials available to potentially affected employees.

• Ensuring that affected employees receive medical surveillance.

• Ensuring that affected employees receive respirator training and fit-testing prior to working with the

respirator, and annually thereafter.

• Supplying approved respirators to affected employees free-of-charge.

• Requiring affected employees to wear respirators.

d. Affected Employees

• Observing the procedures and requirements outlined in this Program.

• Attending training sessions and obtaining medical surveillance.

• Wearing approved respirators as required.

• Notifying supervisors of changes in the workplace that could change exposures.

3. Exposure Assessments

Potential exposures to hazardous materials and conditions at Yale University are routinely evaluated through

regular workplace inspections and upon employee or supervisor request. Environmental Health & Safety takes

all practical efforts to ensure that engineering or other controls are available and implemented to eliminate the

need for respiratory protection. Nevertheless, certain situations and operations continue to require the use of

respirators where exposures cannot be otherwise managed below the applicable permissible exposure limit.

Also, respirators may be required or desired because of the odor or irritation associated with chemical

exposures, even though they may be well below all applicable exposure limits.

In the absence of a regulatory exposure limit, commonly accepted guidelines (i.e., TLVs, RELs, WEELs, or

manufacturers’ suggested exposure limits) will be used to evaluate the exposure hazard from a particular

operation or environment. Airborne concentrations of hazardous agents may be predicted on the basis of past

experience, mathematical calculations, published results for similar work, or actual air sampling. Predicted

airborne concentrations will be extended to all members of the same job title or function unless specific

information indicates that exposures vary substantially, in which case more cross-sectional data will be

obtained. Where air sampling is needed, measurements will be made with calibrated equipment operated by

trained safety and health personnel from, or under the direction of, Yale Environmental Health & Safety.

Monitoring will be repeated when changes occur which could render respiratory protection equipment

inadequate or changes in job tasks will require new employees to be included in this Program.

4. Respirator Selection

Respirators are selected on the basis of workplace hazard assessments, as well as guidance from

29CFR1910.134, the American National Standard Practices for Respiratory Protection Z88.2-2015, the

NIOSH Guide to Industrial Respiratory Protection, and the latest version of the National Institute for

Occupational Safety and Health's Pocket Guide to Chemical Hazards. Final selection of any respiratory

protective device must be made in consultation with senior staff from Environmental Health & Safety. Only

respirators with approval from the National Institute of Occupational Safety and Health (NIOSH) may be

used.

Respirators are selected on the basis of the anticipated health hazard(s), considering the following factors:

• Chemical, physical, or biological agent(s) present in the work environment;

• Physical state of contaminants (i.e., gas, vapor, dust, aerosol);

• Permissible exposure limit (PEL) and immediately dangerous to life and health (IDLH) levels for the

agent. In the absence of a PEL, other suitable exposure guidelines (i.e., ACGIH Threshold Limit Value)

or known toxicity of the agent will be considered;

• Anticipated airborne concentration of agent(s) based upon either past experience, mathematical

predictions, published results from similar operations, or actual air sampling. If the concentration

cannot be predicted or the contaminant(s) unknown, respiratory protection must be upgraded to self-

contained breathing apparatus;

• Assigned protection factor (NIOSH) for the respirator type;

• Potential for skin absorption or severe eye irritation;

• Potential for oxygen deficiency;

• Nature and duration of the activity requiring respiratory protection.

Only respirators that can provide protection in excess of the anticipated airborne concentration will be selected

(i.e., the assigned protection factor times the permissible exposure limit must exceed the anticipated airborne

concentration). The respirator selection worksheet (Appendix B) can be used as a decision guideline for

ensuring the adequacy of selected equipment.

At Yale University, negative pressure air purifying respirators (APR) and powered air purifying respirators

(PAPR) are typically sufficient for routine work operations requiring respiratory protection. Cartridge selection

is made in accordance with the filtration capabilities; the appropriate cartridge or filter can be verified by the

Respirator Program Administrator. Cartridges for gases and vapors must either have an end-of-service-life

indicator (ESLI), or must be changed in accordance with the cartridge change schedule described in Appendix

C. Positive pressure-demand self-contained breathing apparatus (SCBA) is used for emergency response,

unknown or oxygen deficient atmospheres, when there is no appropriate filtering cartridge available, or in other

high hazard situations. A list of approved respirators and their typical uses appears in Appendix D.

5. Restrictions

Respirators requiring a tight face seal for proper performance may not be worn if certain physical or health

conditions prevent obtaining the tight seal. These may include: eyeglasses (with tight fitting full facepiece

respirators); missing denture(s); facial hair or facial jewelry that interferes with the seal; punctured eardrum;

articles of clothing that affect fit; other physical, health, or prosthetic conditions that interrupt or preclude an

effective respirator fit test. Each of these conditions may be remedied as follows:

• Eyeglass Temple Pieces – Where a full-face negative pressure respirator must be worn, a spectacle kit that

fit the respirator must be provided to the employee free-of-charge. The employee will then need to visit an

optometrist during regular working hours to arrange for the lens to be fabricated to the required

prescription. Although the practice is strongly discouraged, contact lenses may be worn provided the

respirator is of full-face design.

• Missing Denture(s) – Will be addressed by the Employee Health Office and the reason for the missing

dentures identified.

• Facial Hair or Facial Jewelry Impeding Effective Seal – Where an employee is required to wear a tight-

fitting negative-pressure respirator, and facial hair or facial jewelry impedes an effective facial seal, the

hair or jewelry must be removed before that respirator can be worn.

• Clothing – Clothing, jewelry, or other personal items worn that prevent making an effective facial seal

must be removed so that the respirator can be properly worn.

• Other Issues – Other issues (e.g., prosthetics, handicaps, facial malformations) that could prevent the

effective use of a respirator will be addressed on a case-by-case basis with the Employee Health Office

during the medical screening.

6. Equipment Acceptance Criteria

Respiratory protection devices, including cartridges for air purifying respirators, must be approved by the

National Institute for Occupational Safety and Health (NIOSH), and Grade D or better compressed air

used in

all air supplying systems. The Yale Office of Fire Code Compliance refills the SCBA tanks through the New

Haven Fire Department, and a certificate of analysis (CofA) verifying Grade D breathing air is available from

them.

7. Fit Testing

Employees who are required to use a tight-fitting respiratory facepiece for protection against all contaminants

must be fit-tested during initial equipment issuance, whenever a different respirator is used (change in type or

make/model) and annually thereafter. In addition to the fit testing, the employee should conduct a respirator

seal check prior to each use. User seal check procedures as mandated by OSHA are outlined in Appendix E.

Qualitative fit testing is performed by Environmental Health & Safety using irritant smoke, saccharin, bitrex, or

isoamyl acetate (“banana oil”). Quantitative fit-testing is performed as necessary using the TSI Portacount.

This fit testing is performed following the procedures mandated by OSHA in Appendix A of 29CFR1910.134.

Fit testing is repeated annually and must also be repeated if the user’s health/physical characteristics

significantly change (e.g., weight gain/loss, surgery, accident, change or loss of dentures). Qualitative fit-

testing verifies an assigned protection factor (APF) of 10 for the disposable N95 and N100 respirators.

Qualitative fit-testing also verifies an APF of 10 for ½ mask and full face respirators. If an APF greater than 10

Compressed Gas Association Commodity Specification G-7.1-1989

is desired, quantitative fit-testing will be conducted for full face air purifying respirators, for an APF up to 50.

Users of the full face masks for the SCBAs used at Yale University are fit tested annually using the quantitative

fit test procedure. Records of fit testing are maintained by Environmental Health & Safety. See Appendix F

for fit-testing procedures and record sheet.

8. Training

Employees and supervisors required to wear respirators during employment at the University receive initial

and annual training in the proper use, care, and limitations of the selected respirator; details of this program;

and on OSHA’s requirements under 1910.134. At a minimum, the following items will be covered during the

training session:

• The nature of the respiratory hazard (i.e., what specific chemical substances or microbiological species are

present; what areas, operations, or conditions involve potentially hazardous exposures; and what effects

(symptoms) may result, if respirators are not used).

• An explanation of why engineering controls are not immediately possible and a discussion of what efforts

are being made to eliminate or minimize the need for respirators.

• An explanation of why the respirator type selected is the proper one and what factors affect selection.

• A discussion and demonstration on how to use the respirator; i.e., how to inspect, put on and remove,

check the seals, etc.

• Instruction on the proper techniques and importance of cleaning, disinfection, inspection, maintenance,

and storage of the respirator.

• A discussion of the capabilities and limitations of respirators (i.e., in what environments or under what

circumstances (such as oxygen deficiency) the respirator does not offer adequate protection) and any

warning signs (odor, etc.) that may indicate the respirator is not functioning properly.

• How to use the respirator effectively in emergency situations, including situations in which the respirator

malfunctions.

• How to recognize medical signs and symptoms that may limit or prevent the effective use of respirators.

• The general requirements of OSHA’s respirator standard.

See Appendix G for an outline of the respirator training program.

9. Voluntary Use

Under some circumstances, employees may wish to use respiratory protection equipment for their own comfort

or sense of well-being, even when there is no recognized hazard or overexposure. Respirator use in these

circumstances would be considered “voluntary” and many elements of OSHA’s respiratory protection standard

would not apply.

Those employees who wear filtering facepieces (N95, N100) on a voluntary basis are provided with the

required information (from 29CRF1910.134, Appendix D). See Appendix H for a copy of the required

information given to these voluntary respirator wearers. They do not require fit testing or medical clearance.

Employees who wear other types of respirators on a voluntary basis (1/2 face APR, FF APR, PAPR) are trained

and fit tested (if applicable) in accordance with the respirator standard and may also attend respiratory

protection training annually. They are also required to complete the medical clearance questionnaire and be

medically cleared to wear a respirator.

10. Equipment Inspection

Employees must inspect their respirator before and after each use, including face seals and shield (full face

units), cartridge receptacles, straps, and inhalation and exhalation diaphragms. Components made of rubber,

silicone, or another elastomer must be inspected for pliability and any signs of deterioration. If any parts are

damaged, the unit must be immediately taken out of service and the area supervisor notified so that a suitable

replacement or repair can be made. Respirators for emergency use and all self-contained breathing apparatus

must also be inspected on a monthly basis (Appendix I). The most current inspection record is kept with the

equipment. A record of the monthly inspection of the SCBAs and PAPRs available for emergency use by EHS

is kept in the EHS office.

11. Equipment Use

When donning a respirator, hair must be pulled back and away from the seal area, and negative and/or positive

pressure seal checks conducted to evaluate the facial fit and unit integrity. If an air-tight seal cannot be made by

adjusting the tightening straps, then the respirator must be inspected for damage and either repaired or replaced.

When using a respirator, employees must immediately stop work and leave the area if they:

• Detect vapor or gas breakthrough, changes in breathing resistance, or leakage or the facepiece,

• Develop any signs or symptoms of over-exposure,

• Are alerted to end-of-service life indicator or low air alarm (for SCBA),

• Are alerted to a low battery condition (PAPR),

• Need to wash their face and respirator facepiece as necessary to prevent eye or skin irritation associated

with respirator use, or

• Need to replace the respirator or the filter, cartridge, or canister elements.

In the event that a possible exposure many have occurred during respirator use, notify the area supervisor,

Environmental Health & Safety, and/or the Employee Health Office for assistance and possible medical follow-

up. Remove the respirator from service and inspect it for damage or other problems. If the cause cannot be

identified and corrected, contact Environmental Health & Safety for guidance.

12. Additional Requirements for Use of Self-Contained Breathing Apparatus (SCBA)

To prevent tampering or inadvertent damage, SCBAs must be stored in clearly identified emergency equipment

areas (or bags) under the direct control of the users. Compressed air cylinders must be kept fully charged and

the equipment inspected on a monthly basis. The inspection includes checking tank pressure, assuring that

components are present and in working condition, and evaluating proper function of regulators and warning

devices. In areas where a user could, upon respirator failure, be overcome by toxic materials or an

oxygen-deficient atmosphere, at least one partner and two additional support or back-up persons must be

present. Support personnel will be equipped with SCBAs and other emergency response equipment of equal or

greater protection than that worn by the initial entrants. Prior to initial entry into such a work area,

Environmental Health & Safety will conduct a pre-entry briefing to discuss the area, its potential hazards, and

the actions to be taken in the event of an accident or emergency. Depending upon the work area, additional

rescue equipment may be needed (e.g., safety harness and retrieval lines). Confined space entry is prohibited

unless the requirements for Yale University's Confined Space Entry Program have been met.

13. Equipment Maintenance and Storage

Respirators should be cleaned with detergent and water after each use, and then air dried before storing. See

Appendix J for respirator cleaning procedures. Shared respirators must be disinfected with either isopropanol

or an elastomer-safe disinfectant such as benzalkonium chloride pads. Store respirators in sealable plastic bags

away from sources of potential contamination, and never stack them under heavy items that could deform the

elastomer facepiece.

In general, air purifying cartridges and canisters should be removed from the respirator after use and discarded.

However, when used for only a short duration against relatively low concentrations of contaminants, cartridges

may be sealed in an impermeable plastic bag and reused at a later date. See cartridge change schedule in

Appendix C. Cartridges can be reused until an end-of-service life indicator activates, the time period indicated

in the cartridge change schedule has elapsed, breakthrough has occurred (i.e., odor detected), or resistance to

breathing is detected, whichever comes first. When storing cartridges for reuse, a written record showing the

date, contaminant(s), and duration of use must be kept with the cartridges. Discard N-95 and other disposable

respirators and dust masks at the end of your shift, or after use.

Repairs to respirators may only be made by the manufacturer, authorized equipment service contractor, or by

University staff trained in such repair. No adjustments or modifications can be made beyond the manufacturer's

recommendations. SCBA air cylinders must be regularly tested

and maintained by a manufacturer-approved

service contractor. Routine cylinder air refilling is typically performed by the New Haven Fire Department.

The entire respirator, including all parts, must be NIOSH or MSHA approved. The approval is for the entire

unit, and any mixing of brands (i.e. North cartridges on an MSA respirator, or inhalation valves for a 3M

respirator on a Honeywell respirator) voids the approval and is prohibited.

14. Medical Surveillance

The following medical services are available to affected employees free-of-charge, at reasonable times and

places during the employees’ normal work hours, by or under the supervision of a physician or licensed health-

care professional (PLHCP), and where applicable, according to recommendations made by OSHA. The

Employee Health Office manages this surveillance work.

a. Medical evaluations are performed on all employees wearing respirators at Yale University prior to

respiratory use (excluding voluntary use of filtering facepieces, where medical surveillance is recommended

but not required). The PLHCP performs the initial evaluation using a medical questionnaire. (See

Appendix K for the medical questionnaire required by 29 CFR 1910.134(e) for respirator medical

surveillance.) A follow-up medical examination is provided for an employee who gives a positive response

to any question among questions 1 through 8 in Section 2, Part A or whose initial medical examination

demonstrates the need for a follow-up medical examination. This questionnaire is available from the

Employee Health Office and is on the EHS web site at https://ehs.yale.edu/

b. Confidential post-exposure medical evaluation and follow-up is made after documented or suspected over-

exposures. Employees must notify their supervisors of such incidents and assist Environmental Health &

Safety in documenting all relevant conditions of the incident. This information will then be provided to the

Employee Health Office to arrange for any required medical follow-up.

c. A written opinion from the healthcare professional will be obtained by the Employee Health Office after the

initial medical qualification examination as well as after any over-exposure incidents. Copies of this

information will be provided to the affected employee.

15. Respirator Program Evaluation

Workplace evaluations will be conducted during normal area walkthroughs and during respirator training

classes. The Respirator Program Administrator will continually evaluate the work areas to ensure that this

program is being properly implemented and that it continues to be effective. This evaluation will include

maintaining an up-to-date list of departments and job titles that require or use respiratory protection (Reference

1). Affected employees shall be regularly consulted about the effectiveness of the respirator program during

walkthroughs and during annual respirator training. This Respiratory Protection Program shall be reviewed

annually.

In the event that re-use of N95s becomes necessary during the pandemic, the University will allow the same

worker to reuse the respirator, as long as the respirator maintains its structural and functional integrity and the

filter material is not physically damaged, soiled, or contaminated (e.g., with blood, body fluids, make-up etc).

The following information will be provided during training to staff who may re-use their respirators:

• Procedures to verify the integrity of the respirator before re-use (i.e., straps are not stretched, filter is not

damaged) and instructions to dispose of it if it is compromised.

• Procedures for a user seal check, which they should perform each time they don the respirator, and

instructions to discard the respirator if they cannot obtain a good fit.

• The appropriate sequence for donning/doffing to prevent contamination.

Additionally, respirator use can provide an additional level of comfort and protection for workers even in

circumstances that do not require a respirator to be used. OSHA’s COVID-19 Emergency Temporary Standard

(ETS) requires training for all employees who may wear a filtering facepiece respirator (e.g., N95) in

circumstances where they are being worn for enhanced protection against COVID-19, in situations where only

facemasks would be required by OSHA. Information on the COVID-19 ETS can be found in Appendix L.

Appendix E: Respirator User Seal Check

RESPIRATOR USER SEAL CHECK

Persons using tight-fitting respirators must perform a user seal check to ensure that an

adequate seal is achieved each time the respirator is put on. Either the positive and negative

pressure checks listed in this appendix, or the respirator manufacturer's recommended user

seal check method must be used. User seal checks are not substitutes for qualitative or

quantitative fit tests.

I. Facepiece Positive and/or Negative Pressure Checks

A. Positive pressure check. Close off the exhalation valve and exhale gently into the facepiece.

The face fit is considered satisfactory if a slight positive pressure can be built up inside the

facepiece without any evidence of outward leakage of air at the seal. For most respirators this

method of leak testing requires the wearer to first remove the exhalation valve cover before

closing off the exhalation valve and then carefully replacing it after the test.

B. Negative pressure check. Close off the inlet opening of the canister or cartridge(s) by

covering with the palm of the hand(s) or by replacing the filter seal(s), inhale gently so that

the facepiece collapses slightly, and hold the breath for ten seconds. The design of the inlet

opening of some cartridges cannot be effectively covered with the palm of the hand. The test

can be performed by covering the inlet opening of the cartridge with a thin latex or nitrile

glove. If the facepiece remains in its slightly collapsed condition and no inward leakage of

air is detected, the tightness of the respirator is considered satisfactory.

II. Manufacturer's Recommended User Seal Check Procedures

The respirator manufacturer's recommended procedures for performing a user seal check

may be used instead of the positive and/or negative pressure check procedures provided that

the employer demonstrates that the manufacturer's procedures are equally effective.

Appendix F: Qualitative Respirator Fit Testing Exercised and Record Sheet

QUALITATIVE RESPIRATOR FIT TESTING EXERCISES

AND RECORD SHEET

Respirator Fit Test Exercises

The test subject shall perform exercises, in the test environment, in the following manner:

(1) Normal breathing. In a normal standing position, without talking, the subject shall breathe normally.

(2) Deep breathing. In a normal standing position, the subject shall breathe slowly and deeply, taking

caution so as not to hyperventilate.

(3) Turning head side to side. Standing in place, the subject shall slowly turn his/her head from side to side

between the extreme positions on each side. The head shall be held at each extreme momentarily so the

subject can inhale at each side.

(4) Moving head up and down. Standing in place, the subject shall slowly move his/her head up and down.

The subject shall be instructed to inhale in the up position (i.e., when looking toward the ceiling).

(5) Talking. The subject shall talk out loud slowly and loud enough so as to be heard clearly by the test

conductor. The subject can read from a prepared text such as the Rainbow Passage, count backward

from 100, or recite a memorized poem or song.

Rainbow Passage

When the sunlight strikes raindrops in the air, they act like a prism and form a rainbow. The

rainbow is a division of white light into many beautiful colors. These take the shape of a long round arch,

with its path high above, and its two ends apparently beyond the horizon. There is, according to legend, a

boiling pot of gold at one end. People look, but no one ever finds it. When a man looks for something

beyond reach, his friends say he is looking for the pot of gold at the end of the rainbow.

(7) Bending over. The test subject shall bend at the waist as if he/she were to touch his/her toes. Jogging in

place shall be substituted for this exercise in those test environments such as shroud type QNFT or

QLFT units that do not permit bending over at the waist.

(8) Normal breathing. Same as exercise (1).

The test subject shall be questioned by the test conductor regarding the comfort of the respirator upon

completion of the protocol. If it has become unacceptable, another model of respirator shall be tried. The

respirator shall not be adjusted once the fit test exercises begin. Any adjustment voids the test, and the fit

test must be repeated. If the wearer smells the test odor, tastes the flavoring, or experiences irritation, the fit is

faulty and another size or style mask must be obtained, or the unit adjusted until a fit is obtained.

Appendix J: Procedures for Cleaning Respirators

Procedures for Cleaning Respirators

A. Remove filters, cartridges, or canisters. Disassemble facepieces by removing speaking

diaphragms, demand and pressure- demand valve assemblies, hoses, or any components

recommended by the manufacturer. Discard or repair any defective parts.

B. Wash components in warm (43 C [110 F] maximum) water with a mild detergent or

with a cleaner recommended by the manufacturer. A stiff bristle (not wire) brush may be

used to facilitate the removal of dirt.

C. Rinse components thoroughly in clean, warm, preferably running water. Drain.

D. 1 When the cleaner used does not contain a disinfecting agent, respirator components

should be immersed for two minutes in one of the following:

a. Hypochlorite solution (50 ppm of chlorine) made by adding approximately one

milliliter of laundry bleach to one liter of warm water; or,

b. Aqueous solution of iodine (50 ppm iodine) made by adding approximately 0.8

milliliters of tincture of iodine (6-8 grams ammonium and/or potassium

iodide/100 cc of 45% alcohol) to one liter of warm water; or,

c. Other commercially available cleansers of equivalent disinfectant quality when

used as directed, if their use is recommended or approved by the respirator

manufacturer.

2. Rinse components thoroughly in clean, warm, preferably running water. Drain. The

importance of thorough rinsing cannot be overemphasized. Detergents or disinfectants

that dry on facepieces may result in dermatitis. In addition, some disinfectants may

cause deterioration of rubber or corrosion of metal parts if not completely removed.

E. Components should be hand-dried with a clean lint-free cloth or air-dried.

F. Reassemble facepiece, replacing filters, cartridges, and canisters where necessary.

G. Test the respirator to ensure that all components work properly.

Appendix L: Safe Use of Respirators Under the OSHA COVID-19 ETS

Respirators can be an effective method of protection against COVID-19 hazards when properly selected and worn.

Respirator use can provide an additional level of comfort and protection for workers even in circumstances that do

not require a respirator to be used. However, if a respirator is used improperly or not kept clean, the respirator itself

can become a hazard to the worker. OSHA’s COVID-19 Emergency Temporary Standard (ETS) requires training for

all employees who may wear a filtering facepiece respirator (e.g., N95) in circumstances where they are being worn

for enhanced protection against COVID-19, in situations where only facemasks would be required by OSHA.

1910.504 – Mini Respiratory Protection Program (“mini RPP”)

• Applies when employees use respirators where only facemasks are required by OSHA.

• In contrast, OSHA’s normal Respiratory Protection Standard (1910.134) applies whenever respirators are

required by OSHA.

Why Is This Training Necessary?

• Wearing a respirator can, in and of itself, can present a hazard, such as:

• Causing difficulty breathing when you have certain underlying medical conditions.

• Causing a facial rash if the respirator has not been properly cleaned or stored.

In order to ensure that the respirator itself does not present a hazard, you need to take certain precautions:

1. Read and follow all instructions provided by the manufacturer on use, maintenance, cleaning and care, and

warnings regarding the respirator’s limitations.

2. Keep track of your respirator so that you do not mistakenly use someone else’s respirator.

3. Do not wear your respirator where other workplace hazards (e.g., chemical exposures) require use of a

respirator. In such cases, your employer must provide you with a respirator that is used in accordance with

OSHA’s Respiratory Protection Standard (1910.134).

Filtering Facepiece Respirators (FFR)

Filtering facepiece respirators, referred to as “FFRs,” are disposable respirators, normally intended for single-use.

They protect you by filtering particles, such as COVID-19 particles, out of the air as you breathe. N95s are the most

commonly used FFRs.

Fit Testing

• A fit test evaluates the fit of a tight-fitting respirator to an individual’s face.

• It verifies that you have found a make, model, and size of respirator that fits to your face.

• Much like finding a style and size of shoe that fits your foot properly.

• Fit testing is required under the normal RPP.

• Fit testing is not required under the mini RPP.

• Without a fit test, there is less control over whether employees are receiving the full, expected level

of protection that a respirator is capable of providing. Therefore, a user seal check is required each

time you put on your respirator.

User Seal Checks

• A user seal check determines whether a tight-fitting respirator has properly sealed to your face once it has

been put on.

• A user seal check must be conducted each time you put on a respirator.

• Two types of user seal checks:

• Positive pressure user seal check - the respirator user exhales.

• Negative pressure user seal check - the respirator user inhales.

To conduct a positive pressure user seal check for a FFR:

1. Once you have conducted proper hand hygiene and properly donned the respirator, place your hands over the

facepiece, covering as much surface area as possible.

2. Exhale gently into the facepiece.

3. The face fit is considered satisfactory if a slight positive pressure is being built up inside the facepiece

without any evidence of outward leakage of air at the seal. Examples of evidence that it is leaking could be:

• The feeling of air movement on your face along the seal of the facepiece.

• Fogging of your glasses.

• A lack of pressure being built up inside the facepiece.

To conduct a negative pressure user seal check:

1. Once you have conducted proper hand hygiene and properly donned the respirator, cover the filter surface

with your hands as much as possible and then inhale.

2. The facepiece should collapse on the wearer’s face and should not feel air passing between the face and

facepiece.

How To Put On And Remove a FFR

Review OSHA’s “Seven Steps to Correctly Wear a Respirator at Work” on the following page. Additionally, you

can watch a video depicting these steps.

Medical Signs and Symptoms

Medical evaluation, to determine if an employee is medically fit to use a respirator, is required under the normal

RPP, but not under the mini RPP. However, it is important to recognize signs and symptoms that could impair your

ability to wear/continue to wear a respirator. These include: shortness of breath, coughing, wheezing, chest pain, or

any other symptoms related to lung problems or cardiovascular symptoms. Discontinue respirator use immediately

and notify your supervisor if you experience any of these conditions while wearing a respirator.

Inspection, Storage and Reuse of FFRs/N95s

Inspect a FFR before each use. Check for damage to the filter, straps, and seal.

The reuse of single-use FFRs is discouraged. However, if an FFR is to be reused, it must only be reused by the

employee it was provided to and only under the following conditions:

• The respirator is not visibly soiled or damaged;

• The respirator has been stored in a breathable storage container (e.g., paper bag) for at least 5 calendar days

between use and has been kept away from water or moisture;

• The employee does a visual check in adequate lighting for damage to the respirator’s fabric or seal;

• The employee successfully completes a user seal check;

• The employee uses proper hand hygiene before putting the respirator on and conducting the user seal check;

and

• The respirator has not been worn more than five days total.
