| The Allegro fit check banana oil ampules are sold in 10 units per box, and they can be used with your existing test kit. When activated, these tubes produce a pungent odor, which smells like banana oil. When used with a test kit, these ampules help you to determine if a respirator should be adjusted or replaced.
Since you get 10 ampules per box, the price for these products is minimal. All respirators should be properly fitted. If they don't fit, they can allow hazardous particulates to enter the lungs of the wearer. These tubes deliver an easy, fast and safe way to perform respirator checks.
They produce a distinctive smell, which is very easy to pick up with your senses. If you're running a test and smell the pungent odor, then you'll need to adjust or replace the respirator you're testing. The problem with respirators that don't fit is a lack of safety.
When a face mask doesn't fit, it allows particulates to enter through the mask, and these particles can end up inside the lungs of the wearer and cause problems. A simple fit test doesn't require a lot of time, and it's required to stay OSHA compliant.
