The 3M™ Sensitivity Solution FT-11 is designed to assess a wearer’s sensitivity to saccharin prior to conducting a qualitative fit test. It is used in conjunction with the 3M™ Qualitative Fit Test Apparatus Kit FT-10 Sweet.
The 3M™ Qualitative Fit Test Apparatus range is intended for fit testing disposable and half-face reusable respirators equipped with particulate filters or combination gas/vapour and particulate pre-filters. 3M™ offers two kit options:
- FT-10 (Sweet) – uses a sodium saccharin solution that produces a sweet-tasting aerosol.
- FT-30 (Bitter) – uses a denatonium benzoate solution that creates a distinctly bitter taste.
Selection between the sweet or bitter test is based on individual sensitivity. While most people can detect saccharin, a small percentage of users cannot. In these cases, the bitter test (FT-30) must be used to ensure accurate fit test results.
