Abstract: The invention relates to a sealing device for a chamber partition, the partition having an orifice enabling a strand of conductor wires to pass between the outside and the inside of the chamber. The device includes a plug through which passes the strand, and an apparatus to keep the plug pressed against the partition. The conductor wires can be kept away from one another inside the plug to ensure the seal-tightness of the plug itself. Advantageously, the plug is pressed into a void of a counter-form, the internal shape of the void substantially complementing an external shape of the plug. The form/counter-form assembly provides for a perfect seal-tightness.

Abstract: A two-piece protective suit for use in hazardous environments includes a coat and trousers each of which includes an outer garment and a removable liner, the outer garment including an outer shell made of a flame protective material and an inner layer of a material which is moisture resistant and resistant to the passage of hazardous chemical and/or biological agents and liquids, the coat including a bottom closure mechanism to tighten the bottom of the coat towards the waist of a wearer and inhibit hazardous material entry in the coat from below, left and right cuff closure mechanisms to tighten the left and right cuffs towards the left and right arms of a wearer and inhibit hazardous material entry into the left and right sleeves, and a hood and neck tab which are deployable over the head and neck of a wearer and over a face mask worn by the wearer to protect the head and neck of a wear from the hazardous materials and inhibit entry into the coat through its neck opening.
