摘要

The suit for a person working in potentially explosive environment e.g. oil refineries and chemical plants, comprises an envelope forming waterproof wall, which is positioned in part of the person, pipe supply forming the waterproof wall having an interior end connected to a fluid source located out of the hostile environment and an exterior end connected to seal with the inside of the envelope, and a vent unit in communication with inside of the envelope. The envelope wall and the manifold fluid supply wall have part of an electrically conductive material both sides. The suit for a person working in potentially explosive environment e.g. oil refineries and chemical plants, comprises an envelope forming waterproof wall, which is positioned in part of the person, pipe supply forming the waterproof wall having an interior end connected to a fluid source located out of the hostile environment and an exterior end connected to seal with the inside of the envelope, and a vent unit in communication with inside of the envelope. The envelope wall and the manifold fluid supply wall have part of an electrically conductive material both sides. The walls are consecutive and arranged in a manner to constitute together a continuous electric driver that envelops a point of the pipe situated outside of the hostile environment. The envelope walls and the pipe are plastic material in which dopant has good electrical conductivity. The plastic material is a material made from polyethylene vinyl acetate. The envelope walls of electrically conductive material are constituted by the entire wall. The pipe of electrically conductive material is constituted by a metallic deposit on the surface of the pipe. The pipe supply has mounted in series. An element controls the flow of the fluid. The element is conformed according to the norms of atmosphere explosive standards. The envelope is total combination, partial combination, hood and helmet. The envelope wall and pipe supply are fireproofed.
