Which machine does OCFRD use for fit testing?

• A. Protacount Plus
• B. Portacount Pro
• C. FitTest Pro
• D. Quantifit 3

Answer: (A)

Quantitative fit testing uses a specialized instrument to measure how well a respirator seals on the wearer’s face by comparing particle concentrations inside and outside the facepiece during a series of movements. OCFRD uses Protacount Plus for this task. The device works by generating an ambient aerosol, then a particle counter inside the facepiece determines the fit factor, giving a numerical result that indicates whether the seal is adequate. Protacount Plus is the department’s chosen system because it aligns with their testing protocols and respirator models. The other models are different fit-testing systems, but they aren’t the ones OCFRD has designated for routine use.
