VeriFit® Irritant Smoke Generator for Respirator Fit Testing (10 PK)

Complete, Safe, Ready-to-Use, and OSHA-Compliant

The VeriFit Irritant Smoke Generator is a complete, safe, ready-to-use, and OSHA-compliant fit testing kit. Its patented design integrates all traditional irritant smoke test components into one convenient device.

All-in-One, Ready-to-Use Design

The VeriFit Irritant Smoke Generator’s patented all-in-one design saves you prep and clean-up time. All aspects of a traditional irritant smoke fit test kit are incorporated into one handy device.

There are also no additional components to attach, lose, or replace. The bellows and ampoule are conveniently integrated into a sleek smoke generator.

With the VeriFit, there is no need for nebulizers, pumps, mixing jars, batteries, test masks, probes, or hoods. There are no parts to calibrate, warm up, sterilize, or clean. It’s always ready to use.

Precise Testing, Objective Results

The VeriFit Irritant Smoke Generator’s bellows produce a precise volume of air with each complete compression. There is no user calibration or complex, error-prone flow rate to set. Because you control the compressions, you control the amount of smoke generated. Manual operation ensures greater safety and precision.

What Causes False Negative Results?

A common cause of false negative results is the failure of a test subject to identify a leak in the respirator. Qualitative fit tests such as banana oil (isoamyl acetate), saccharin, or Bitrex may cause false negative results.

Many factors cause test subjects to not notice a leak:

• Olfactory fatigue (reduction in ability to smell)
• Gustatory fatigue (reduction in ability to taste)
• Allergy or common cold
• Ingestion of food or drink
• Reduced sense of smell or taste due to aging, smoking, or other causes

Irritant smoke is the only OSHA-accepted qualitative fit testing method that relies on the test subject’s involuntary response. It does not rely upon test subject’s sense of smell or taste.

Reduced Health Risk, Minimal Risk of Overexposure

Irritant smoke fit testing simulates real working conditions. At no time are test subjects required to hold their breath after vigorous exercise, a potentially stressful condition that could be detrimental to the test subject’s health. Also, there are no test hoods; test subjects are allowed to breathe normally through the entire test.

The risk of overexposure to smoke is also minimized due to the small bellows size. The VeriFit Irritant Smoke Generator is a safer option than traditional irritant smoke test kits that can have less precise smoke measurements or greater smoke production.

Safer Construction

The VeriFit Irritant Smoke Generator’s plastic construction is a safer alternative than traditional irritant smoke test kits. Traditional kits use glass tubes that must be broken to elicit smoke. The broken glass can become hazardous to handle and discard.

To use a VeriFit Irritant Smoke Generator, simply bend the plastic tube to break the enclosed ampoule. Because the ampoule is inside the tube, there is no danger of exposure to broken glass. As a result, the VeriFit Irritant Smoke Generator is safer to operate and discard.
