No, you cannot test a full face mask using the qualitative fit testing method. This is because full face masks require a much higher fit factor than qualitative fit testing can measure.

The Health and Safety Executive (HSE) has conducted studies showing that a poor fit on a full face mask cannot be reliably detected using qualitative methods. Instead, a quantitative fit test must be used. This method provides a numerical measurement of the seal’s effectiveness and ensures the required protection level is achieved.

Using an unsuitable test method may result in an unsafe fit, compromising the respiratory protection the mask is designed to provide.

Key points:

• Full face masks require a high fit factor to ensure proper protection.
• Qualitative fit testing cannot detect a poor fit on full face masks.
• HSE research supports the need for quantitative testing for full face masks.
• Only quantitative fit testing gives a reliable seal performance measurement.
• Using the wrong test method could lead to inadequate respiratory protection.
