Abstract
A sealing device for positive pressure testing is attached to a respirator face mask and includes an outer frame integrally joined to a movable cap by a flexible link that biases the cap in an open position for the operational use of the face mask against a manually applied force to move the cap to a sealed position for the positive pressure testing to assure the proper fit of the face mask on the wearer. The method for positive pressure testing includes flexibly moving the sealing device from the open position to the sealing position such that the sealing surface of the cap seals the exhalation valve assembly closed. The wearer then exhales into the mask to test the seal of the mask. When the test is completed, the sealing device is released and the inherent biasing force moves the cap from the sealing position to the open position.
