    This lab uses a required-user scenario. Federal OSHA’s voluntary-use provisions differ: an employer must ensure use creates no hazard and provide Appendix D information; solely voluntary filtering-facepiece use is excepted from the written-program requirement. Other voluntary respirator use needs the applicable medical/cleaning/maintenance program elements. Calling use voluntary does not override a required-use hazard.

    A surgical/procedure mask or cloth covering is not a NIOSH-approved respirator. KN95 is a different standard designation and does not by itself establish NIOSH approval. A surgical N95 adds applicable healthcare fluid-resistance requirements; an ordinary N95 is not automatically a surgical N95.

    Teaching assumptions, limits & primary sources

    Federal OSHA 29 CFR 1910.134 and its Appendix A provide the reference framework. 3M FT-10 (sweet saccharin) and FT-30 (bitter denatonium benzoate) identify real kits; the kit drawings are original generic teaching schematics, not product photographs, model-specific donning instructions, official 3M software or an endorsement. Respirator illustrations are credited CDC/NIOSH details from the linked 2019/2023 charts; they are separate from the fictional N-05 device and are not fit or donning instructions. Follow the actual kit/respirator instructions and applicable employer, industry and jurisdiction requirements.

    The kit activity is limited to the supplied negative-pressure N95 half-mask scenario. QLFT is limited under federal OSHA to negative-pressure APR uses requiring a fit factor of 100 or less. Do not generalize this activity to full-facepiece APF 50 use, tight-fitting PAPRs/SARs, CBRN, emergency entry or other protocols. A QLFT is pass/fail; a QNFT measures a fit factor; filter efficiency and APF are different. No maximum-use concentration can be established from the supplied data.

    All eight illustrated families are broad equipment categories; quarter/half/full, tight/loose fit, operating mode and the complete approval matter. The nine N/R/P classes shown apply to non-powered particle filters; PAPRs use their own approved filter classifications, including HE and PAPR100-N/PAPR100-P. R/P oil resistance never means unlimited service life. Cartridges remove only their specified contaminants and need an appropriate ESLI or an objective-information change schedule; smell is not a change schedule.

    An N95, elastomeric APR or PAPR supplies no oxygen. Do not enter an unknown, oxygen-deficient or IDLH atmosphere based on this lab. Qualified personnel need the exact compliant atmosphere-supplying system and full entry/rescue arrangements. No entry instruction or rescue role is assigned here.

    Actual tests require a capable administrator, proper equipment, screening and full protocol. Check aerosol generation/clogging; keep nebulizers and solutions separate; never return used solution to stock bottles. Follow current kit cleaning/disposal instructions. This activity omits physical preparation, filling, actual wear/wait periods and exposure administration. Accelerated checkpoints cannot time a real test.
