The Allegro 2055-DLX Deluxe Irritant Smoke Fit Test Kit is designed for qualitative respirator fit testing using stannic chloride smoke tubes. This OSHA-accepted QLFT method helps safety managers, EHS teams, industrial hygienists, and respiratory protection program administrators check tight-fitting respirator face seals by observing whether the test subject detects or reacts to irritant smoke.
This deluxe kit is built for field use, contractor safety programs, industrial hygiene work, manufacturing facilities, and jobsite respirator testing. The rugged hard case helps protect the smoke tubes, aspirator bulb, rubber caps, and fit test documentation during transport and storage.
Unlike Bitrex or saccharin fit testing, irritant smoke testing does not require a test hood. The smoke is directed around the respirator seal area while the worker performs the required fit test exercises. If the worker detects the irritant smoke during the test, the respirator fit is considered unsatisfactory and the worker must be refitted and retested.
Bulk Ordering & Procurement Support
Need irritant smoke fit test kits, smoke tubes, Bitrex kits, banana oil kits, or respirator testing supplies for a facility, contractor crew, government site, manufacturing plant, or safety program? ASA Supplies supports business, government, municipal, contractor, facility, and industrial purchasing teams with bulk quote support, volume pricing, purchase orders, and sourcing assistance.
Safety & Compliance Note
Irritant smoke fit testing must be performed carefully because stannic chloride smoke can irritate the eyes, lungs, and nasal passages. OSHA Appendix A states that irritant smoke testing requires respirators equipped with high-efficiency particulate air or P100 series filters. Do not use this kit for standard N95 respirator fit testing. For N95 fit testing, use Bitrex or saccharin where qualitative fit testing is allowed.

Buying Guide: Irritant Smoke vs. Bitrex Fit Test Kits
Choose the Allegro 2055-DLX Irritant Smoke Fit Test Kit when your respiratory protection program uses tight-fitting respirators equipped with P100 or HEPA filters and your trained fit test administrator is prepared to follow the OSHA irritant smoke protocol.
Choose Bitrex or saccharin for standard N95 fit testing. Bitrex and saccharin use taste response inside a hood and are commonly used for disposable filtering facepiece respirators. Irritant smoke is not the right choice for standard N95 masks because OSHA requires HEPA or P100 series filters for this protocol.
FAQ
What is the Allegro 2055-DLX Irritant Smoke Fit Test Kit used for?
It is used for qualitative respirator fit testing with stannic chloride smoke as part of an OSHA respiratory protection program.
Can this kit be used for N95 masks?
No. Standard N95 respirators should not be fit tested with irritant smoke. Use Bitrex or saccharin for N95 fit testing where qualitative fit testing is allowed.
Does irritant smoke testing require a hood?
No. OSHA’s irritant smoke protocol does not use a hood. The smoke is directed around the respirator seal area.
What filters are required for irritant smoke fit testing?
OSHA states that respirators tested with irritant smoke must be equipped with HEPA or P100 series filters.
What happens if the worker detects the smoke?
If the worker detects irritant smoke during the test, the fit is unsatisfactory and the respirator fit test fails.
Is this a quantitative fit test kit?
No. This is a qualitative fit test kit. It does not provide a numeric fit factor.
How often must fit testing be conducted?
OSHA 1910.134 requires annual fit testing, plus additional testing when there is a change in respirator model, style, size, or when the worker reports a physical change that could affect fit.
