At Colossal Consultants, we are dedicated to ensuring the utmost safety for your workforce through our expert Face Fit testing services. Properly fitting respiratory protective equipment (RPE) is essential for protecting against airborne hazards in various industrial and commercial settings.

The Importance of Face Fit Testing

Face Fit testing is essential to verify that the chosen RPE effectively seals against the wearer’s face, thereby providing the intended protection. Poorly fitting masks can result in leaks, exposing the wearer to dangerous substances. This testing ensures that the RPE fits well and functions correctly during regular use.

Types of Face Fit Tests

  1. Qualitative Fit Test (QLFT): This method is used for disposable respirators and reusable half masks. It involves a test agent with a distinct taste, such as saccharin or Bitrex. The wearer performs several exercises while wearing the mask, and the presence of the test agent inside the mask indicates a poor fit​​.
  2. Quantitative Fit Test (QNFT): Suitable for full-face masks, this method uses specialized equipment to measure the exact amount of leakage into the mask. Techniques include using a condensation nuclei counter (CNC) or a controlled negative pressure (CNP) device. This test provides a numerical fit factor, indicating the mask's effectiveness in sealing against the face​​.

Preparation for the Test

  • Facial Hair: Ensure you are clean-shaven as facial hair can disrupt the seal of the mask.
  • Avoid Certain Activities: Do not eat, drink (except water), smoke, or chew gum for at least 30 minutes before the test to ensure accurate results.
  • Health and Hygiene: Be in good health and remove any facial piercings that might interfere with the mask's fit.

What to Expect During the Test

  • Sensitivity Check: The initial phase involves a sensitivity test without the mask to determine your ability to detect the test agent used in QLFT.
  • Fit Test Procedure: You will then wear the mask and perform a series of movements, such as turning your head and speaking, to ensure the mask maintains its seal during different activities​.

Scheduling a Face Fit Test

Our certified professionals conduct each test, typically lasting around 30 minutes. After the test, you will receive a detailed report indicating whether the facepiece fits properly. If the fit is unsatisfactory, we will help you find an alternative mask that fits better. Passing results are specific to the make and model of the facepiece used during testing.
