Medical Evaluation Requirements Explained

Overview

Before an employee uses a respirator in the workplace, OSHA Standard 1910.134 requires a medical evaluation to determine their physical ability to safely perform work while wearing respiratory protection. This requirement protects both the employer and employee by identifying potential health risks before they become serious problems.

Why Medical Evaluations Are Required

Physiological Burden of Respirators

Wearing a respirator increases physiological demands on the body:

Increased Work of Breathing:

• Resistance from filters/cartridges
• Dead space in facepiece
• Weight of equipment
• Restricted air flow

Cardiovascular Stress:

• Increased heart rate
• Elevated blood pressure
• Greater oxygen demand
• Heat stress concerns

Psychological Factors:

• Claustrophobia or anxiety
• Communication difficulties
• Reduced field of vision
• Sense of isolation

Pre-Existing Conditions

Certain medical conditions may be aggravated by respirator use:

• Asthma or chronic obstructive pulmonary disease (COPD)
• Heart disease or irregular heartbeat
• High blood pressure
• Anxiety disorders or claustrophobia
• Previous lung injuries or surgeries
• Certain medications affecting breathing or heart rate

The medical evaluation identifies these conditions before they pose a risk.

The Medical Evaluation Process

Step 1: Medical Evaluation Questionnaire (MEQ)

Every employee must complete OSHA's mandatory Medical Evaluation Questionnaire found in Appendix C of 1910.134.

Questionnaire Sections:

Part A: Employer Information

• Company name and address
• Type of respirator
• Weight and type of filters/cartridges
• Job location and description
• Expected duration of use
• Expected physical work effort
• Additional protective equipment
• Temperature and humidity conditions

Part B: Employee Confidential Medical Information

• Age, height, weight
• Medical history questions
• Current symptoms
• Prior respirator use

Key Questions Include:

1. Do you currently smoke tobacco or have you smoked in the last month?
2. Have you ever had breathing problems?
3. Do you currently have heart trouble, heart attack, stroke, or other cardiovascular problems?
4. Have you ever had asthma, chronic bronchitis, emphysema, or other lung problems?
5. Do you have claustrophobia or problems wearing close-fitting equipment?
6. Have you ever had vision problems?

Step 2: PLHCP Review

A Physician or Other Licensed Health Care Professional (PLHCP) reviews the completed questionnaire.

Qualified PLHCPs Include:

• Physicians (MD or DO)
• Physician assistants
• Nurse practitioners
• Other licensed healthcare professionals authorized to provide medical evaluations

PLHCP Evaluation: The PLHCP reviews responses and determines:

• Medical clearance without restrictions
• Medical clearance with limitations
• Need for additional medical examination
• Denial of clearance

Step 3: Additional Medical Examination (if needed)

Based on questionnaire review, the PLHCP may require a follow-up examination including:

Physical Examination:

• Blood pressure measurement
• Heart rate and rhythm
• Lung auscultation
• Cardiovascular assessment
• Weight and BMI calculation

Additional Tests (as indicated):

• Spirometry (lung function test)
• Chest X-ray
• Electrocardiogram (EKG)
• Exercise tolerance test
• Blood work
• Stress test

Considerations:

• Type of respirator (filtering facepiece vs. SCBA)
• Duration of use (occasional vs. continuous)
• Work intensity (light duty vs. heavy labor)
• Environmental conditions (heat, cold, altitude)
• Age and general health status

Step 4: Written Recommendation

The PLHCP provides a written recommendation to the employer containing:

Required Elements:

1. Whether employee medically able to use respirator
2. Any limitations on respirator use
3. Need and frequency of future medical evaluations
4. Statement that PLHCP provided copy of written recommendation to employee

Prohibited Information:

• Specific medical diagnoses
• Detailed medical findings
• Personal health information

Confidentiality: All medical information remains strictly confidential between employee and PLHCP.

Clearance Outcomes

Full Clearance

Employee is cleared to:

Next Steps:

• Proceed to fit testing
• Begin respirator training
• Receive assigned respirator

Conditional Clearance

Clearance with limitations such as:

• Use only certain respirator types (e.g., PAPR instead of negative-pressure)
• Limit duration of continuous use
• Require rest breaks
• Restrict work intensity
• Monitor for specific symptoms

Implementation:

• Supervisor notified of restrictions
• Accommodations put in place
• Employee educated on limitations
• Follow-up evaluation scheduled

Medical Examination Required

Additional evaluation needed:

• In-person physician examination
• Diagnostic testing (spirometry, EKG, etc.)
• Specialist consultation
• Further assessment before determination

Process:

• Referral provided
• Employee schedules examination
• Results sent to PLHCP
• Final determination made

Not Cleared

Employee cannot use respirator due to:

• Significant medical condition
• High risk of adverse event
• Inability to meet physiological demands

Employer Options:

• Engineering controls to eliminate need
• Administrative controls to reduce exposure
• Alternative job assignment
• Reasonable accommodation discussion

Frequency of Medical Evaluations

Initial Evaluation

Required before:

• First-time respirator use
• Fit testing
• Training with actual respirator

Periodic Re-Evaluation

Additional medical evaluations required when:

1. Employee Reports Medical Signs/Symptoms

• Chest pain or shortness of breath
• Dizziness or lightheadedness
• Breathing difficulty when using respirator
• Any concerning symptoms

2. PLHCP, Supervisor, or Program Administrator Recommends

• Based on health surveillance
• Observation of difficulty
• Changes in medical status
• Age-related concerns

3. Information from Respiratory Protection Program Indicates Need

• Fit test difficulties
• Employee reports discomfort
• Observed compliance issues
• Program evaluation findings

4. Change in Workplace Conditions

• More protective respirator required
• Increased duration of use
• Higher work intensity
• Extreme temperature exposure
• Additional weight or restriction

Routine Re-Evaluation

While OSHA doesn't mandate a specific frequency, many employers require:

• Annual evaluations
• Biennial evaluations
• Age-based (annually after age 50)
• Risk-based frequency

Special Considerations

Voluntary Use

Even when respirator use is voluntary (not required), medical evaluation recommended for:

• Tight-fitting respirators
• Employees with known health conditions
• Extended duration use
• Strenuous work activities

Exception: Filtering facepieces (N95, etc.) used voluntarily may not require medical evaluation if:

• Use is truly voluntary
• No occupational exposure standards violated
• Employee informed of Appendix D information

Emergency Use Respirators

Employees assigned emergency escape respirators need medical clearance appropriate to:

• Type of emergency escape respirator
• Expected duration of escape
• Physical demands of evacuation
• Potential stress of emergency

SCBA and Airline Respirators

More rigorous medical evaluation required for:

• Self-Contained Breathing Apparatus (SCBA)
• Supplied-air respirators
• Any respirator in IDLH conditions

Enhanced Evaluation May Include:

• Exercise stress testing
• Pulmonary function tests
• Cardiovascular assessment
• Physical fitness evaluation

Common Medical Clearance Issues
