Description

Sealing member wrapping a cable and method for preventing smoke spread from one area to a surrounding area The present invention relates to a sealing member that encloses a cable passing through a penetration device mounted in a bulkhead, as defined in the preamble of an independent claim, and a method for preventing smoke from spreading from one area to a surrounding area. Various types of sealing members are generally used to isolate spaces from one another to prevent the spread of smoke or fire from one area to a surrounding area. These sealing members are typically mounted on bulkheads, such as partitions, floors, ship decks, ceilings, or firewalls, through which cables, hoses, or other materials pass. An example of such a sealing member includes a wall penetration device mounted on a bulkhead before a cable passes through it. In a firefighting assembly known as EP3299688 A1, a cloth is attached to the wall penetration device by fastening elements. The cloth is additionally attached to the cable, hose, or other material by two additional straps to form a substantially airtight passage. The problem with the solution of the prior art is to provide a sealing member that can be mounted even after a cable, hose, tube, or other application passes through a bulkhead. For example, if replacement of a cloth and/or wall penetration device is required due to maintenance of the cloth and/or wall penetration device, according to the prior art, the cable must be removed before mounting the cloth and/or wall penetration device. In addition, a problem with solutions known in the prior art is the ease and speed of mounting the sealing member. Therefore, an improved sealing member is required that can be mounted after creating a passage in the bulkhead and guiding the cable through the bulkhead, and can be easily mounted to a penetration device. The object of the present invention is to mitigate, reduce, or eliminate one or more of the aforementioned defects and disadvantages of the prior art, and to solve at least the aforementioned problems. Another objective of the present invention is to provide a sealing member and a method for preventing fire, smoke, or gas from spreading to a surrounding area through a penetration of a bulkhead in an area filled with fire, smoke, or gas. According to a first embodiment, a sealing member is provided for wrapping a cable passing through a penetration device mounted on a bulkhead. The sealing member comprises a wrapping cloth having a first end and a second end located opposite the first end, wherein the first end is configured to be mounted around the periphery of a protrusion of the penetration device, and the wrapping cloth is configured to wrap the cable. The wrapping cloth is further configured to seal the cable at a position between the first end and the second end, and the first end of the wrapping cloth is provided with a first folded hem forming a first cavity having an outer open end and an inner open end. A third opening is provided in the first folded end, and the interior of the cavity is accessible through the third opening so that a steel-band type fastening means can be inserted between the third opening and the outer open end, and the third opening is located in the middle section along the length of the first end. A bulkhead is, for example, a partition, floor, ceiling, or firewall of a building or ship. A penetration device is a device designed to allow a cable to pass through a hole in a bulkhead. A penetration device allows a cable to pass through a fireproof bulkhead and deck. The penetration device is filled with an inflatable material. An inflatable material is a material that expands when exposed to heat, such as in a fire situation, and rapidly seals the passage of fire, smoke, or gas. In one embodiment, the inflatable material begins to expand at about 160°C. The penetration device is mounted in the bulkhead and extends outward from the bulkhead so that a sealing member can be mounted around the perimeter of the penetration device. The sealing member may also be suitable for wrapping hoses, pipes, or other similar types of materials. The sealing member may be substantially rectangular or square in shape. The sealing member may also have other suitable shapes. The first and second ends may have lengths that create an overlap when folded along the perimeter of the penetration device. It is preferable that the overlap be shorter than the distance between the inner open end and the third opening so that a steel-band type fastening means can access it through the third opening. The steel-band type fastening means may be a metal fastening strap, such as a metal hose clamp, a metal cable tie, or any similar type of fastening means. Metal fastening straps have excellent heat resistance, ensuring that the insulation sleeve is securely fastened even in the event of a fire, while also representing a cost-effective solution. Furthermore, metal fastening straps are read
