  • the suit advantageously includes a pocket placed inside the jacket at the level of its back, this pocket being intended to contain the suit folded after use.
  • suit 1 a single-use waterproof individual protection suit 1 in accordance with the invention, hereinafter called suit 1, the latter being intended to be worn by a user who is, or is about to enter, in an area containment, for example, for asbestos removal operations.
  • combination 1 is preferably manufactured from either a non-woven textile made of polypropylene (PP) or polyethylene (PE), or from a woven textile made of PP fibers, or PE fibers, or made of natural fibers such as, for example, cotton or even a mixture of natural fibers and synthetic fibers, for example, polyester.
  • combination 1 is intended to be worn jointly with gloves G, shoes C or overshoes and a full respiratory protection mask, not shown in the figures.
  • the term “complete respiratory protection mask” means a mask covering the eyes, nose, mouth and chin of the user and comprising at least one skirt of flexible material capable of coming into tight contact with the face of the user.
  • user a visor, retaining straps and an inner half-mask provided with an inspiratory valve and a connection intended to receive a filter or an air supply system.
  • additional equipment means said gloves G, shoes C or overshoes and a filtering protective mask.
  • Combination 1 is classically composed of several pieces of textile assembled together by sewing.
  • the combination 1 preferably comprises along each of said seams seal-reinforcing members, not shown, composed of a strip of fabric preferably heat-sealed, said fabric advantageously being composed of 'a blend of nylon/polyester, thermal polyurethane (TPU) and acrylic glue.
  • TPU thermal polyurethane
  • said sealing reinforcement members could also be an adhesive placed along each of said seams and consisting of a polyolefin support covered with a mass of pressure-sensitive acrylic glue and 'a removable non-stick strip made from a polyolefin support.
  • said combination 1 comprises at least one jacket 2 provided with two sleeves 3 and a hood 4, and pants 5 comprising two legs 6, the combination 1 advantageously being an integral combination in one piece, that is to say say that pants 5 are permanently attached to jacket 2.
  • the suit 1 according to the invention may not be in one piece and may comprise a jacket 2 and independent pants 5 capable of being fixed in a watertight manner to said jacket 2 by any appropriate fixing technique, without leaving the framework of the present invention.
  • the suit 1 comprises opening means 7 extending vertically from the bottom of the opening 41 of the hood 4 to at least the bottom of the jacket 2, preferably to the crotch of the pants 5, and being advantageously of the quick zipper type.
