The 3M Fit Test FT30 is a control accessory for 3M half masks that can be used to carry out a taste test to check the fit of particle-filtering half masks and half masks with particle or combination filters. The test kit contains a bonnet with a cuff, which the test person wears without respiratory protection in the first round. The sweet-tasting sensitivity test solution is then sprayed into the bonnet using a nebuliser. The amount required for the test person to taste the solution when inhaling is the indicator for the test amount for the second run. Here, the test person wears the respiratory protection to be tested under the bonnet. After a few movement and breathing exercises that simulate realistic use of the mask, the fit test solution is sprayed into the bonnet. If the test person tastes nothing, the mask fits tightly and provides reliable protection. However, if the taste test is positive and this is also the case during a control run, the mask is unsuitable for the shape of the test person's face.
