Respirator Fit Testing

Qualitative respirator fit and pulmonary function tests

From my physical, to the drawing of my blood, the staff was very professional and I was pleased.

Respirator Fit Testing

Respirator Fit Test

Employees working a position that is regulated by OSHA Respirator Standard CFR 1910.134 are required to have a respirator fit testing done at least once a year. The test is always done before working with a new mask or after changes in the employee’s facial characteristics. Annual or more frequent tests ensure a continuous protection against mask wear and tear and facial changes.

Respirator Fit Testing (RFT) is mandated by the Occupational Safety & Health Administration (OSHA) on the federal level and state level for most localities. Failure to comply can be costly to employers who are fined up to $7,000 for the first offense and $70,000 for repeated offenses. These penalties are much higher when compared to a RFT that averages under $100 per test.

Respirator Fit Testing Information

Qualitative Respirator Fit Test

For job positions where a mask is required, Mobile Health specializes in the affordable and effective testing procedure called Qualitative testing. In this test, the employee wears the facemask along with a hood over their head. The tester then applies a series of test agents and gauges the employee’s ability to detect the smells and tastes. Individuals who are able to detect these agents must have their mask adjusted or changed for proper fitting.

The test agents generally used include:

  • Saccharin – a sweet tasting solid aerosol.
  • Isoamyl acetate – a liquid that produces a sweet smelling vapor similar to bananas.
  • BitrexTM – a bitter tasting solid aerosol.
  • Irritant smoke – a solid aerosol made of stannic oxychloride that produces hydrochloric acid when it comes in contact with water vapor.

Pulmonary Function Test

Many times a respirator fit test is done along with a Pulmonary Function Test (PFT), also known as a Spirometry. Whereas the respirator fit testing ensures the mask worn is the right fit and model for the employee, the pulmonary function test actually gauges the employee’s lung health. Most often, employers use this test to develop a baseline to compare future against future tests.

Having this established baseline is a good protection when evaluating the cause of worker’s compensation claims, as well as making sure employees have the adequate protection necessary to perform their job.

As with the qualitative respirator fit testing, Mobile Health also offers pulmonary function tests (spirometry) at all six medical facilities in New York City and Long Island.

Respiratory Hazards

Employers must provide respirator masks and fit testing to employees when any of the following hazards are present in the work environment:

  • Dust and Fibers: Solid particles formed from mechanical process. Ex: lead, asbestos
  • Fumes: Solid particles that vaporizes and condenses in cool air. Ex: welding fumes
  • Mists: Liquid droplets suspended in air from spraying operations. Ex: paint spray mist
  • Gases: Individual molecules in the air at room temperature. Ex: carbon monoxide
  • Vapors: Gaseous substances normally liquid or solid in room temperature. Ex: solvents
  • Biological Hazards: Living organisms that can cause infections. Ex: viruses, animal waste

Different Assigned Protection Factors (APF) and Maximum Use Concentrations (MUC) will determine the appropriate respirator mask to be used.
