Claims
- 1. A sheet having two expansive surfaces and being fluid-impervious where not penetrated, a grommet adhering to one of the expansive surfaces of the sheet but not penetrating the sheet, the grommet outlining a region on the sheet, wherein the region outlined by the grommet is fluid-impervious before being penetrated and wherein the grommet is adapted, if an object penetrates the sheet and fits tightly through the grommet, to provide a fluid-impervious seal around the object.
- 2. The sheet of claim 1, as combined with an object penetrating the region outlined by the grommet and fitting tightly through the grommet, which provides a fluid-impervious seal around the object.
- 3. For a hazardous environment, a protective garment having the sheet of claim 1, as combined with a breathing or air-filtering apparatus comprising elements inside the protective garment, elements outside the protective garment, and a tube connecting the inside and outside elements, penetrating the region outlined by the grommet, and fitting tightly through the grommet, which provides a fluid-impervious seal around the tube.
