Device for Fit Testing of Gas Masks

A gas mask fit testing device, comprising:

• a reservoir for containing a fit testing composition;
• a cap creating an effective air tight seal on the reservoir;
• a first sealed ampoule containing a gas mask fit test composition, wherein the sealed ampoule is within the reservoir and the breakable walls of the ampoule and the gas mask fit test composition, wherein a breakable wall of the ampoule separates the solvent from the gas mask fit test component from the interior volume of the reservoir;
• and
• an outlet for the gas mask fit testing component to be delivered for a fit test or a threshold test.

A gas mask fit test device, comprising:

• a reservoir for containing a fit testing component;
• a cap creating an effective air tight seal on the reservoir;
• a solvent contained within the reservoir of the gas mask fit test device;
• a first sealed ampoule with a breakable wall, the first sealed ampoule containing a gas mask fit test component, wherein the first sealed ampoule is within the reservoir and the breakable wall of the ampoule separate the gas mask fit test component from the solvent and the gas mask fit test component is soluble in the solvent, wherein a breakable wall of the ampoule separates the solvent from the gas mask fit test component.

A method of conducting a fit test, comprising:

• breaking a first sealed ampoule within a reservoir to release a fit test component to prepare a threshold fit test composition;
• spraying the threshold fit test composition from the reservoir in an area around a person to be fit tested for a gas mask;
• perceiving an indication from the person to determine whether the person senses the fit test component;
• breaking a second sealed ampoule within a reservoir to release more of the fit test component to prepare a fit test composition;
• spraying the fit test composition from the reservoir in an area around a person wearing a gas mask;
• and
• determining an indication from the person wearing the gas mask whether the person senses the fit test component within the gas mask.
