This invention relates to a fire proof or fire resistant container typically used for the protection of control boxes, actuators and other electrical or mechanical systems in the event of a fire. The container 10 consists of a base portion 9 and side walls 2a-d. A lid portion (30, figure 2) is also provided. The walls of the container comprise a plurality of layers, including an outer insulating layer 1 formed from a first synthetic fibre material layer, an intermediate layer 5 of fire resistant material and an inner layer 8 consisting of regions of a second synthetic fibre material and regions of an intumescent material. The synthetic fibre may be manufactured from a polymer such as a polyamide or a polysilic acid, and the fire resistant material may be a plastic such as glass reinforced plastic. The container may further comprise ports 17 or openings through which cables may be received. Each port may comprise a seal and may extend through one or more walls of the container, preferably through at least one of the portions of intumescent material 7a-b. |
