What Is A Respirator Fit Test?

A respirator fit test can be described as a type of testing protocol that is conducted with the intent to certify that a respirator fits someone’s face in a way that is both comfortable and also effectively provides that person with the protection that is expected. Typically in a respirator fit test, the person wearing the mask will be exposed to a testing agent, and then the wearer’s reaction, lack of reaction, detection, or lack of detection of the agent will be recorded by the fit tester or measured with a specified instrument. Some testing agents are designed to have an odor or certain taste, and others are designed to cause reactions such as coughing when a wearer is exposed to them.

Respirator Fit Testing Methods: Qualitative And Quantitative

The most important distinction when looking at qualitative vs. quantitative respirator fit testing is that qualitative testing relies on the wearer’s senses to notice leaks. On the other hand, with quantitative testing, leakage is measured with instruments and does not rely on the wearer to provide information.

Qualitative Fit Testing

With a qualitative fit test, the results of the test either end in a passing score or a failing score. A qualitative fit test often uses the wearer’s senses of taste and smell or even their reaction or lack of reaction to a specific agent. If the wearer smells, tastes, or has a reaction to the agent that is being used, it can be concluded that there is a leakage issue with the respirator, and it is not fit to be used in an actual hazardous environment. There are four different agents used in a qualitative fit test that are also accepted under OSHA standards. These four different agents are:

  • Isoamyl Acetate, which has an odor similar to bananas
  • Bitrex, which is designed to cause a bitter taste for the wearer
  • Irritant Smoke, which causes the wearer to cough
  • Saccharin, which is designed to cause a sweet taste for the wearer

Quantitative Fit Testing

A quantitative respirator fit test determines effectiveness as well, but while the results of the test will still end with either a passing or failing score, these scores are now determined by measured amounts of actual leakage instead of relying on the wearer’s senses or physical responses. In quantitative testing, the respirator is attached to a machine that is used to interpret and record leakage results, and if these results do not meet the necessary criteria, they are determined to be unusable in real-world hazardous situations. There are three different agents used in quantitative fit testing that are also accepted under OSHA standards. These three different agents are:

  • A Generated Aerosol Agent
  • A Controlled Negative Pressure Agent
  • An Ambient Aerosol Agent

Respiratory Hazards And Who We Help

In the majority of situations, respirators are used to protect the human respiratory system against harmful dusts, mists, paint vapors, solvents, and more. With the help of properly fitted respirators, many contaminants in the air that can caused bodily harm if inhaled can be filtered out. Some of the many industries that commonly used respirator masks include:

  • Manufacturing
  • Automotive
  • Mining
  • Petroleum, Oil, And Gasoline
  • Natural Gas/Gas Extraction
  • Painting
  • Construction And Demolition
  • And More

Respiratory hazards that are blocked by these respirator masks can be extremely dangerous if inhaled. If workers in these industries do not wear respirators or do not wear them properly, serious bodily injury or even death could be possible if inhalation occurs.

Benefits Of Fit Testing

With the help of respirator fit testing, workers and employers alike can confidently know that safety precautions are being taken seriously. Respirator testing ensures that workers are wearing a tight-fitting respirator mask properly so that the full effectiveness of these mask’s filtration properties can be utilized.
