Introduction to 3M FT‑32 Bitter Fit Test Solution

The 3M FT 32 Fit Test Solution (Bitter) is a professional-grade qualitative fit test solution containing denatonium benzoate (Bitrex™).
Designed for use with 3M’s qualitative fit test apparatus (FT‑30, FT‑20, FT‑10), this bitter aerosol helps evaluate respirator face‑seal efficacy and compliance with OSHA 29 CFR 1910.134 Appendix A and various international standards

Key Features & Benefits

• • • • Bitter Test Solution:
        Includes denatonium benzoate, producing an unmistakably bitter taste when respirator fit is inadequate
      • OSHA & CE Compliant:
        Meets performance criteria for qualitative respiratory fit testing as per OSHA and CE standards
      • Versatile Usage:
        Suitable for particulate and gas/vapor respirators with particulate prefilters, applicable across multiple industries
      • Professional Packaging:
        Supplied in a 55 mL clear, odorless, non-hazardous solution—enough for approximately 200 fit test procedures
      • Occupational-Only:
        Intended exclusively for trained industrial users and workplace programs.

How It Works

1. 1. Sensitivity Screening:
      A lighter taste version (FT‑31) is used to ensure test subjects can detect bitterness.
   2. Fit Test:
      If sensitivity passes, the FT‑32 bitter solution is nebulized inside the hood while the subject performs breathing and movement exercises.
   3. Detection:
      Detection of bitterness indicates improper seal, prompting device adjustment and retesting. No taste signifies a proper, leak-free fit

Applications & Use Cases

• • • Healthcare, Construction & Manufacturing:
      Critical in N95, half‑face, or full‑face respirator programs for aerosol exposure .
    • Safety Compliance:
      Assists employers in meeting OSHA regulations and ensuring worker protection.
    • Training:
      Supports safety training initiatives to train workers in correct respirator usage, sealing, and fit verification.

Technical & Safety Data

The FT‑32 solution is clear, odorless (aside from bitter taste), and non‑hazardous per OSHA and international hazard criteria.
