1. A respirator mask comprising:
a facepiece including a regulator engagement region having:
an aperture; and
a protrusion proximate the aperture;
wherein the facepiece further includes an interior surface and an exterior surface opposite the interior surface, the protrusion extending a distance from the facepiece exterior surface;
and,
a regulator including:
a regulator body having a facepiece engagement region mateably engageable with the regulator engagement region;
a fluid flow path within the regulator body configured to receive pressurized air from a tank; and
a latch within the regulator body, the latch configured to cause obstruction of the fluid flow path when actuated; and
at least a portion of the regulator being sized and configured to be received within the facepiece aperture such that the latch is engageable with the protrusion, the regulator being rotatable within the facepiece aperture between a first rotational position that is an installed position and a second rotational position that is an uninstalled position, such that rotation of the regulator within the facepiece aperture from the second rotational position to the first rotational position engages the protrusion of the facepiece with a protrusion engagement element of the latch and actuates the latch to obstruct the fluid flow path.
