A system for the management of information relating to the installation of firestopping systems within one or more facilities by contractors includes a network server and client devices that interact with the network server via a computer network. The client devices may be associated with administrators and contractors. The network server collects information from the contractors that describes a penetration of a fire-rated structure or an installation of a fire-rated duct, and direct a database server to generate a record for the penetration or duct based on the collected information and store the record in a database. The information may include the contractor, an authorizer, work-type, location, and one or more firestopping systems to be installed. The network server may provide the contractors with lists of permissible selections for the information. The network server may generate these lists from information stored in the database that was previously provided by administrators.

Managing information relating to firestopping systems

A fire stopping faceplate assembly for an electrical box includes a faceplate having an inner surface, and a fire stopping mat arranged adjacent said faceplate inner surface. The fire stopping mat provides an active system which forms a fire barrier capable of preventing a temperature rise on the wall side opposite the fire by providing an endothermic material which withdraws heat and/or by expanding to provide additional insulating properties and otherwise stopping the spread of fire. The fire stopping mat may include an intumescent compound, an endothermic compound, or both an intumescent compound and an endothermic compound. The fire stopping mat may also include a layer of an infrared blocking material formed of, for example, a metal or a ceramic fiber material.
