Device for fit testing of gas masks |
| abstract |
Fit testing is conduct to ensure that gas mask provide proper protection to workers that may be exposed to airborne contamination. Standard fit test procedures require the mixing of fit test compounds to specific fit testing composition required for threshold testing and subsequent fit testing. A device is needed for easy mixing of the components of the fit test composition and easy delivery of fit test composition during a fit test. For example, a device for fit testing of a gas mask on an individual wearer may include a sprayer, at least one ampoule containing a fit testing component, and a reservoir containing the ampoule and a solvent for the fit test component. The reservoir may be hollow body having a sealed inner volume. The reservoir may be deformable to break at least one hermetically sealed ampoule without tearing or otherwise breaking the reservoir. Therefore, the ampoule may be broken within the reservoir to mix the gas mask fit testing component into the solvent to generate the desired concentration for either a threshold test or gas mask fit test. |
