ABSTRACT:
A fluid-impervious sheet has two expansive surfaces, to one of which an elastomeric grommet adheres. The elastomeric grommet, which is annular when unstressed, outlines a region on the fluid-impervious sheet. The elastic grommet is adapted to provide a fluid-impervious seal around an object penetrating the region outlined by the elastomeric grommet and fitting tightly through the elastomeric grommet. A protective garment for a hazardous environment is made from the fluid-impervious sheet and has a breathing apparatus, which comprises elements inside the protective garment, elements outside the protective garment, and a tube connecting the inside and outside elements. The tube penetrates the region outlined by the elastomeric grommet and fits tightly through the elastomeric grommet, which provides a fluid-impervious seal around the tube.
