Abstract
Disclosed is a personnel protective apparatus which includes a helmet and a full face shield attachable to the helmet. The helmet includes a facial opening having a resilient edge roll thereabout. The face shield has a resilient seal bonded thereto which includes a face sealing portion adapted to form a seal about the face and a helmet sealing portion adapted to engage the edge roll and form a seal about the facial opening. The face sealing portion includes a first inwardly directed pressure energized seal which engages the face and a second outwardly directed pressure energized seal to engage the face. The helmet sealing portion includes a channel formed to encircle the face shield and cooperate with the edge roll of the helmet to urge the second shield into better sealing engagement with the face.
