ABSTRACT:
A personal protective suit for a wearer includes a hood portion located generally above the wearer's neck and at least partially enveloping the wearer's nose and mouth, a body portion located generally below the wearer's neck and at least partially enveloping the wearer's torso, an air delivery system that can deliver air to the hood portion, a vent that can permit gasses to escape from the body portion, and a partial flow restriction between the hood portion and body portion of the suit. The partial flow restriction permits gasses to pass from the hood portion to the body portion while reducing carbon dioxide levels in front of the wearer's mouth. The suit can be fabricated without requiring a face piece.
