N95 Medical Clearance Requirements for Healthcare Workers: Complete Guide
Comprehensive guide to OSHA medical clearance requirements for healthcare workers using N95 respirators, including annual evaluations, voluntary vs mandatory use, Joint Commission compliance, and streamlined online clearance options.
Published January 22, 2025
Quick Answer: N95 Medical Clearance Requirements
OSHA requires all healthcare workers using N95 respirators—whether mandatory or voluntary—to complete medical evaluations before first use and annually thereafter. Workers complete the OSHA Appendix C questionnaire, which is reviewed by a licensed PLHCP. Medical clearance certificates must be maintained on file and available for Joint Commission and OSHA inspections.
N95 respirators have become standard personal protective equipment in healthcare settings, especially following the COVID-19 pandemic. While many healthcare facilities focused on securing adequate N95 supplies during shortages, many now struggle with OSHA compliance requirements for medical clearance and fit testing.
The confusion is understandable. During COVID-19 emergencies, OSHA temporarily relaxed enforcement of some respiratory protection requirements. Those temporary measures have ended. As of 2025, healthcare facilities must comply with full OSHA 1910.134 requirements—including medical evaluations for every healthcare worker using N95 respirators.
This guide explains exactly what OSHA requires for respirator medical evaluations, how to streamline compliance for busy healthcare staff, and how online medical evaluations can save thousands of dollars and hundreds of staff hours annually.

OSHA Requirements for Healthcare N95 Use
Healthcare facilities using N95 respirators must comply with OSHA's Respiratory Protection Standard (29 CFR 1910.134). This applies to hospitals, clinics, nursing homes, home health agencies, dental offices, and any healthcare setting where respirators are used.
Core Requirements Summary
| Requirement | When Required | Frequency |
|---|---|---|
| Medical Evaluation | Before first N95 use | Initial + annual renewal |
| Fit Testing | After medical clearance, before N95 use | Annual + when changing N95 models |
| Training | Before first N95 use | Initial + annual refresher |
| Written Program | When any employee uses respirators | Maintain and update as needed |
| Documentation | All of the above | Maintain for duration of employment + 30 years |
Mandatory vs Voluntary N95 Use: What's the Difference?
One of the most common questions in healthcare respiratory protection is whether medical clearance is required for "voluntary" N95 use. The short answer: Yes, medical clearance is still required.
Mandatory Use (Full Program Required)
Mandatory use means the employer requires respirators to protect against specific hazards. In healthcare, this includes:
- Tuberculosis (TB) exposure
Airborne infection isolation rooms, suspected or confirmed TB patients
- Airborne precautions
COVID-19, measles, chickenpox, SARS, novel respiratory viruses
- Aerosol-generating procedures
Intubation, bronchoscopy, suctioning, nebulizer treatments (facility policy dependent)
- Pandemic response
Facility designates N95s as required PPE during outbreaks
Requirements for mandatory use: Full OSHA 1910.134 compliance including written program, medical evaluations, fit testing, training, maintenance, and documentation.
Voluntary Use (Partial Requirements)
Voluntary use means the employer permits (but does not require) respirator use, and the employee chooses to wear one for extra protection when not mandated.
Why medical clearance is still required for voluntary N95 use:
- N95s are tight-fitting respirators that increase work of breathing
- Healthcare work involves physical exertion (patient lifting, rapid response, long shifts)
- Workers with undiagnosed heart/lung conditions may experience health events
- OSHA requires employers to protect employee health even during voluntary use
The Medical Evaluation Process for Healthcare Workers
The medical evaluation determines if a healthcare worker can safely wear an N95 respirator based on their health conditions.
What's Evaluated
Healthcare workers complete the OSHA Appendix C questionnaire, which covers:
Cardiovascular Health
Heart disease or chest pain
High blood pressure
Heart attacks or heart problems
Medications affecting heart rate
Respiratory Health
Asthma or breathing problems
Chronic bronchitis or emphysema
Shortness of breath at rest or exertion
Lung disease or reduced lung capacity
Psychological Factors
Claustrophobia or panic attacks
Vision or hearing limitations
Difficulty communicating with mask
Anxiety about wearing respirators
Work Environment
Physical demands of healthcare work
Hot environments or extended wear time
Pregnancy status
Communication requirements with patients
PLHCP Review and Clearance
A Physician or Licensed Healthcare Professional (PLHCP) reviews the questionnaire and determines if the worker can:
- Full clearance
Use any respirator type without restrictions
- Clearance with restrictions
Approved for certain respirator types only (e.g., PAPR instead of N95, limited wear time)
- Denied clearance
Not approved for respirator use; may require further medical evaluation or treatment
Annual vs Initial Medical Evaluations
Healthcare workers need two types of medical evaluations:
| Evaluation Type | When Required | What's Involved |
|---|---|---|
| Initial Evaluation | Before first N95 use | Complete OSHA Appendix C questionnaire; PLHCP review and clearance decision |
| Annual Renewal | Every 12 months | Re-complete questionnaire to identify health changes; PLHCP review and renewed clearance |
| Additional Evaluation | When health changes occur | New medical conditions, medications, breathing difficulty, weight changes, pregnancy |
| Follow-Up Evaluation | PLHCP requests more info | Additional medical exam, pulmonary function test, stress test, specialist consultation |
Online Medical Evaluations: Streamlined Solution for Healthcare Facilities
Traditional occupational health clinic evaluations create significant challenges for healthcare facilities with large nursing staffs, shift workers, and 24/7 operations.
The Clinic-Based Challenge
Traditional Clinic Evaluations
- Cost: $75-150 per nurse
For a 100-nurse facility: $7,500-15,000 annually
- Time: 3-4 hours per nurse
Travel, waiting, exam, travel back = missed shift time
- Scheduling nightmare
Coordinating 100 nurses across shifts with clinic hours
- Lost productivity
300-400 nursing hours for 100 staff = $15,000-20,000 in labor costs
- Compliance gaps
Missed appointments lead to expired clearances
Online Evaluations (RespiratorTest)
- Cost: $22 per nurse
For a 100-nurse facility: $2,200 annually (85% savings)
- Time: 15-20 minutes per nurse
Complete during break, between shifts, or at home
- 24/7 availability
Night shift, weekend, holidays—anytime access
- Zero lost productivity
Nurses stay on-site, no travel time or waiting rooms
- Automated tracking
Email reminders before expiration, digital certificates
Annual savings for a 100-nurse facility:
- Medical evaluation costs: $13,000 savings ($15,000 clinic vs $2,200 online)
- Lost productivity costs: $17,500 savings (350 hours @ $50/hour)
- Administrative time: $3,000 savings (reduced scheduling coordination)
- Total annual savings: $33,500 for 100 nurses
Joint Commission Requirements for N95 Compliance
The Joint Commission (TJC) requires accredited healthcare facilities to comply with OSHA respiratory protection standards, including medical evaluations and fit testing.
What Joint Commission Surveyors Check
- Written respiratory protection program
Documented program addressing OSHA 1910.134 elements
- Medical clearance documentation
Current clearance certificates for all staff using N95s
- Fit test records
Annual fit testing documentation with test results
- Training records
Initial and annual refresher training for respirator users
- Program evaluation
Annual review and updates to respiratory protection program
COVID-19 Era Changes and Current Requirements
During COVID-19, OSHA issued temporary enforcement discretion policies allowing some flexibility in respiratory protection compliance. These emergency measures have ended.
What Changed After COVID-19
| During COVID-19 Emergency | Current Requirements (2025) |
|---|---|
| Enforcement discretion for medical evaluations | Full medical evaluation required before N95 use |
| Flexibility for fit testing during shortages | Annual fit testing required for all N95 users |
| Extended wear and re-use policies allowed | Follow manufacturer instructions; single-use N95s for single shift |
| Crisis capacity strategies (decontamination) | No longer permitted unless new emergency declared |
| Voluntary use without evaluations (some facilities) | Medical evaluation required even for voluntary tight-fitting respirator use |
Healthcare facilities that deferred medical evaluations or fit testing during COVID-19 must now complete these requirements for all staff using N95s. Online medical evaluations provide the fastest, most cost-effective path to full compliance.

Frequently Asked Questions
Do healthcare workers need medical clearance for N95 respirators?
Yes. OSHA requires medical clearance before healthcare workers use N95 respirators, whether for mandatory protection (TB, COVID-19, measles) or voluntary use. Workers must complete the OSHA Appendix C questionnaire, which is reviewed by a PLHCP who issues a medical clearance certificate.
What is the difference between voluntary and mandatory N95 use in healthcare?
Mandatory use means the employer requires respirators for specific hazards (TB, COVID-19, airborne precautions). Full OSHA 1910.134 compliance is required including medical evaluations, fit testing, and training. Voluntary use means the worker chooses to wear an N95 for extra protection when not required. Medical evaluation and fit testing are still required for tight-fitting respirators, even when voluntary.
How often do healthcare workers need N95 medical clearance?
Healthcare workers need initial medical clearance before first N95 use, then annual renewal. Additional evaluations are required if health changes occur (new medical conditions, breathing difficulties, significant weight change, pregnancy) or if the worker reports difficulty wearing the respirator.
Can nurses and healthcare staff complete N95 medical evaluations online?
Yes. OSHA allows online medical evaluations for healthcare workers. Staff complete the OSHA Appendix C questionnaire online (15 minutes), and a licensed PLHCP reviews answers and issues clearance certificates. Online evaluations cost $22 vs $75-150 at occupational health clinics and are available 24/7.
What does the Joint Commission require for N95 respirators?
The Joint Commission requires healthcare facilities to comply with OSHA respiratory protection standards, including medical evaluations and fit testing for N95 respirators. TJC surveyors verify documentation during accreditation surveys and can issue findings for non-compliance with respiratory protection requirements.
Does N95 medical clearance expire?
Yes. N95 medical clearance expires after 12 months and must be renewed annually. However, clearance can expire sooner if health conditions change, the worker reports difficulty breathing while wearing the N95, or a PLHCP places time-limited restrictions on respirator use.
What happens if a healthcare worker fails N95 medical clearance?
If a worker fails medical clearance, the PLHCP may: recommend restrictions (lighter-weight respirator, PAPR instead of N95), require additional medical evaluation or treatment, temporarily deny clearance until conditions improve, or permanently deny clearance. The employer must accommodate by reassigning duties or providing alternative protection like PAPRs.
Are COVID-19 era emergency waivers still in effect for N95 medical clearance?
No. Emergency temporary standards and enforcement discretion policies from COVID-19 have ended. As of 2025, all healthcare facilities must comply with full OSHA 1910.134 requirements including medical evaluations and fit testing for N95 respirators. There are no current waivers or exemptions.
Can healthcare workers share N95 respirators between staff?
No. Each healthcare worker must be fit tested for the specific N95 model and size they use. Sharing respirators between staff members violates OSHA fit testing requirements and compromises protection. Each worker needs their own properly fitted respirator.
What is the difference between fit testing and medical clearance for N95s?
Medical clearance determines if you are medically able to wear an N95 safely based on your health. Fit testing verifies that a specific N95 model creates a proper seal on your face. You need medical clearance first, then fit testing. Both are required annually and serve different purposes.
