## Overview

The Allegro 2050-01 Replacement Smoke Tubes provide six OSHA-compliant stannic chloride tubes with caps designed for qualitative respirator fit testing. Engineered for easy insertion into the Allegro 2050 Smoke Test Kit, these tubes emit a visible irritant smoke to detect leaks and confirm proper respirator fit, ensuring workplace safety and regulatory compliance. Trusted by professionals since 1987, these cost-effective refills keep your fit testing program running smoothly without the need for full kit replacements.

## Description

When activated, Stannic Chloride is a white colorless gas with a pungent odor. It fumes strongly in moist air forming white hydrochloric acid fume. The emitted tin compound has a strong odor that will provoke an involuntary reaction (i.e. coughing) by the test subject.

Review: Fit Test revealed - Have used this product many years no issues with testing.
Review: Great Product, Easy to Use - In my opinion, these are the best option for fit testing. Stop those that try to sneak under the radar, there’s absolutely no way to fake it with the irritant smoke.
