Estimating the term…
An apparatus having a face mask removably attachable to a firefighting hood is provided. The face mask used in cooperation with a breathing apparatus such as a self-contained breathing assembly or a respirator. The face mask has a rim supporting a seal member that operatively sealingly engages the user's face providing a breathing chamber between the user's face and the face mask that is sealed off from the external environment. The firefighting hood has a compliant material enclosing the wearer's head and a support frame surrounding a front opening in the firefighting hood exposing the wearer's face. The firefighting hood matingly engages the face mask such that a perimeter portion of the firefighting hood around the front opening is nested behind the rim of the face mask so as to prevent gaps between the firefighting hood and the face mask. A fastener system attaches the face mask to the firefighting hood to retain the nested arrangement of the perimeter portion of the firefighting hood in an attached position of the face mask to the firefighting hood.
A protective hood for use with a face mask for protecting an individual from elements associated with a firefighting site, the face mask having an annular rim having a front side, a rear side, an inner side, and an outer side, a seal member secured to the rim and adapted for sealing engagement with the individual's face, the seal member configured so as to define an annular recess between a portion of the seal member and the rear side of the rim, and a face plate extending across the rim and cooperating with the rim and the seal member to form a breathing chamber when the seal member is in sealing engagement with the individual's face, the hood comprising:
