The 3M 7010315854 is a probed particulate respirator rated N100, designed exclusively for quantitative fit testing (QNFT) procedures. This unit is not approved for respiratory protection in contaminated environments and must never be used as a substitute for a standard protective respirator. The respirator features a factory-installed probe port that allows fit test equipment to sample air inside the facepiece during a QNFT protocol. Safety officers, industrial hygienists, and occupational health professionals use this unit to verify proper seal and fit on workers before assigning them a respirator for actual use.
This probed respirator is used in workplace fit testing programs governed by OSHA 29 CFR 1910.134 and similar regulatory standards. It is suited for industrial, construction, manufacturing, and healthcare settings where quantitative fit testing is required before workers are cleared to use N100 or equivalent respiratory protection. The unit ships in case quantity and is intended for institutional and program-level procurement.
Designed for use with quantitative fit test equipment in OSHA-compliant fit testing programs where an N100-class probed respirator is required. Specific equipment compatibility should be verified against the fit test system manufacturer requirements.
This respirator is used by qualified safety or occupational health personnel administering quantitative fit tests — it is not installed in a mechanical system. Before conducting a fit test, confirm the probe port is undamaged and the probe connection is secure. Do not issue this unit to workers as protective equipment under any circumstances. Follow the fit test protocol as defined in OSHA 29 CFR 1910.134 Appendix A.
