Fit Testing for respiratory protection

Work safely - with respiratory protection that fits.

—

One of the main reasons why respirators often do not provide the expected protection is an inadequate fit. Dräger's comprehensive range of Fit Testing options offers you the assurance that all your employees are optimally protected by a custom-fit mask.

Even under the toughest conditions, respiratory protection must be reliable so that work can be safe. With Dräger's Fit Testing you can rest assured that you’ll meet necessary requirements.

Qualitative Face Fit Testing

A qualitative fit test checks the sealing of respirators using a substance that the test person can taste or smell.

First, a sensitivity test is performed to ensure that the test person is aware of the substance. The particle-filtering half mask is put on and a special hood is then placed on the subject's head to create a closed-air atmosphere. Afterwards, the test substance is sprayed into the hood and the test person indicates whether he/she detects it or not. If the subject does not indicate that he/she detects the substance, this particular mask type and size provides the optimal individual protection.

Quantitative Face Fit Testing

A quantitative fit test provides objective results.

These are either formed with the help of a particle counter - namely by the ratio of particles in the ambient air to the particles inside the mask - or by measuring leakages with the help of a controlled negative pressure. The result of the tests with the selected method is referred to as the fit factor. If the required factor is not achieved, the subject must select a different mask size or perhaps even a different, more suitable mask model.

Frequently asked questions (FAQs)

—

According to the requirements laid out in the Health & Safety Executives (HSE) guidance note HSE INDG 479 and HSG53 care must be taken to ensure that respirators fit perfectly. By performing fit tests, you can be sure that you meet these requirements.

The seal fit must be rechecked for the following changes in mask or wearer:

weight changes
major dental treatments
facial piercings
new PPE that may affect the seal fit
change of mask types, models or materials

The so-called fit factor confirms when a tested mask meets the requirements for the desired sealing at the time of the test.

Loose-fitting respiratory protection such as hoods for air purifying respirators or escape devices which use a mouthpiece do not require a fit test.

The passing or failing of a qualitative fit test depends on whether the test person can taste or smell the test substance or not and thus provides subjective results. A quantitative fit test provides objective results by using a particle counter or controlled negative pressure to measure the sealing of the mask. Both methods are acceptable. So you can choose the method that is most appropriate for the respirator being used and its wearer.
