A respiratory mask body defining a breathable air zone for a wearer and having a shut-off valve is provided. In an exemplary embodiment, the mask body includes one or more inlet ports configured to receive one or more breathing air source components. The shut-off valve is operable between a closed position and an open position, and when in a closed position the shut-off valve prevents fluid communication between the one or more inlet ports and the breathable air zone and the shut-off valve returns to an open position in the absence of an applied force.

Respirator negative pressure fit check devices and methods

A respiratory protection device that includes a valve assembly operable between an open configuration and a closed configuration. In some exemplary embodiments, the respiratory protection device includes an elastomeric seal, and a valve assembly and a breathing air source component are in sealing engagement with the elastomeric seal when the valve assembly is in the closed configuration.

Respirator fit check sealing devices and methods

A respirator device having an elastomeric sleeve is provided. In an exemplary embodiment, a respirator device as described herein includes a rigid nozzle element and a body including a receiver having an elastomeric sleeve. The elastomeric sleeve defines a channel, and the elastomeric sleeve is configured to deform around the nozzle element when the nozzle element is inserted into the channel.

Respirator with floating elastomeric sleeve

A respiratory protection device that includes a valve assembly operable between an open configuration and a closed configuration. In some exemplary embodiments, the respiratory protection device includes an elastomeric seal, and a valve assembly and a breathing air source component that are in sealing engagement with the elastomeric seal when the valve assembly is in a closed configuration.

A buckle assembly for selectively connecting first and second straps of a personal protective device. The buckle assembly includes a receiver member and a latch member configured for coupling to a respective one of the straps. The receiver member defines a slot and provides a release arm. The latch member includes a latch tab pivotally connected to a base. In a latched state in which the latch member is disposed within the slot and a latch face is engaged with a capture surface. The release arm disposed over a portion of the latch tab. The latch face can be disengaged from the capture surface in response to an actuation force applied to the release arm. In some embodiments, the receiver member and the latch member incorporate various, complimentary guide surfaces that promote easy insertion of the latch member into the receiver member.

Personal protective device strap connecting buckle assembly

A respirator apparatus includes a respirator body, a filter cartridge receiver integral with and extending from the respirator body, and a filter cartridge. The filter cartridge includes a nozzle element being integral with the filter cartridge. The respirator body and filter cartridge are configured to be fluidically coupled through sleeve-fit engagement between the filter cartridge receiver and nozzle element and the filter cartridge receiver and nozzle element define an airflow channel.
