摘要
A single use disposable respirator fit test hood includes front and rear panels joined together along a left and right side edges, and a top edge with an adhesive, particularly a Pressure Sensitive Adhesive. The front panel is provided with an aperture through which test substances are introduced into interior cavity defined by the front and back panels. The test subject inserts their head through an opening defined by the bottom edges of the front and rear panels. During fabrication, shoulder pieces are cut off the front and rear panels to give the bottom edges a generally truncated V-shape. A portion of each shaped bottom edge rests on the test subject's shoulders. The hood is able to remain upright because of the thickness of the film used for the front and rear panels and the presence of the strips of pressure sensitive adhesive.
