According to the Occupational Safety and Health Administration (OSHA), around 5 million workers in the U.S. are required to wear respirators in their jobs. Respirators can be life-saving, especially in environments with harmful airborne particles, chemicals, or low oxygen levels. But they’re only effective if they fit properly and the wearer is medically cleared to use them. That’s where employee respiratory fit testing, DOT physical exams, and health checks come into play—three crucial procedures that safeguard both employees and employers.
What is Employee Respiratory Fit Testing and Health Check?
Employee respiratory fit testing and health check is a required process to determine if a staff member can safely wear a respirator and whether the respirator fits them properly. It ensures that respiratory equipment is functioning as intended and that the individual’s health allows safe usage.
These tests are mandated by OSHA for any job role where respirator use is required. The fit test makes sure the mask seals properly on the wearer’s face, while the health check ensures they are physically capable of using one without risk.
Why Do Employees Need Respiratory Fit Testing?
Not every face shape is compatible with every respirator model. A loose or incorrect fit can allow hazardous particles to leak in, defeating the purpose of the respirator. Meanwhile, wearing one improperly without a health evaluation could cause breathing difficulties or worsen underlying medical conditions.
Before an employee dons a respirator, especially in jobs involving dust, fumes, gases, or chemicals, they must be:
- Medically evaluated.
- Properly fit-tested with the exact make and model of the respirator.
- Re-evaluated if there are changes in their health or facial structure (e.g., weight loss/gain, dental surgery).
What’s Included in a Health Check for Respirator Use?
An employee health check for respirator use goes beyond a general physical. It is tailored to assess respiratory function and overall health as it relates to wearing tight-fitting PPE.
These health checks typically include:
- Medical questionnaires per OSHA standard 29 CFR 1910.134, reviewed by a licensed healthcare professional.
- Pulmonary function testing (PFT), if indicated.
- Cardiovascular evaluation, especially for those with preexisting heart conditions.
- Review of medications that might affect respiratory function.
The goal is to ensure that wearing a respirator won’t place unnecessary strain on the employee—especially when it comes to breathing and overall chest comfort, which can sometimes raise health concerns similar to those discussed in our article, “Can Urgent Care Help Chest Pressure? Find Out Here.”
What are the Types of Respirator Fit Tests?
Respirator fit testing can be conducted using two primary methods, depending on the type of respirator and the level of exposure risk:
Qualitative Fit Test (QLFT)
This is a pass/fail method using the wearer’s senses (taste, smell, or reaction to a test agent like Bitrex or saccharin).
- Used for half-face respirators, like N95 masks.
- Involves a hood placed over the employee’s head.
- If the person can detect the agent’s taste or smell, the fit has failed.
Quantitative Fit Test (QNFT)
This method uses a machine to measure leakage around the face seal and provides a numerical fit factor.
- Required for full-face respirators or in high-risk environments.
- Uses devices like Portacount to measure air inside and outside the mask.
- More precise and suitable for tight-fitting respirators in critical roles.
Both tests require the respirator to be the exact model the worker will use on the job.

How Often Should Respirator Fit Testing and Health Checks Be Done?
OSHA mandates that fit testing be performed:
- Before the first use of the respirator.
- Annually thereafter.
- Whenever there’s a change in the employee’s facial structure (e.g., weight fluctuation, dental surgery).
- If the employee reports issues with the respirator or discomfort.
Health checks should be completed:
- Before fit testing.
- Every 1-2 years, depending on medical guidance.
- Anytime a worker reports symptoms or changes in health that could affect respirator use.
Who Needs These Services?
Employee respiratory fit testing and health check services are crucial for workers in:
- Construction
- Chemical manufacturing
- Emergency services
- Mining
- Pharmaceuticals
- Healthcare
- Waste management
- Agriculture
Essentially, any role with exposure to particulates, chemicals, or biological agents should ensure respiratory safety through regular checks and testing.
How to Prepare Staff for Fit Testing
Before the scheduled test, employees should be informed and prepared. Preparation improves the accuracy of results and compliance with protocols.
Tips to prepare:
- Be clean-shaven. Facial hair interferes with the mask seal.
- Avoid eating, drinking, smoking, or chewing gum 30 minutes before testing.
- Wear the same PPE setup they use at work (e.g., face shields, glasses).
- Bring the exact respirator model they plan to use.
- Complete the health questionnaire honestly and in advance.
What Makes an Effective Fit Testing Program?
A successful respiratory protection program is more than just checking boxes. It’s about creating a safety culture.
Components of a successful program:
- Regular, scheduled testing and medical evaluations.
- Comprehensive record-keeping for audits and inspections.
- On-site or off-site flexibility to suit workforce schedules.
- Clear employee communication and training.
- Follow-up protocols for failed tests or flagged health issues.
Having all elements in place results in reduced workplace illness, increased productivity, and better regulatory compliance.
What Happens After the Testing?
Following the testing, employees receive one of the following:

This documentation must be retained for at least two years and presented upon request by OSHA inspectors.
