Abstract:
1. A lightweight portable fire resistant containment system comprising; a) an outer shell having an outer surface and an inner surface; b) an inner shell having an outer surface and interior surface fitting inside the inner surface of said outer shell creating an air gap between said outer shell and said inner shell, wherein said air gap is unobstructedly and continuously formed by a space between the entire outer surface of said inner shell and said inner surface of said outer shell; c) a lid closing the outer shell, and defining an enclosed space for protecting valuable photographs and documents from fire damage; d) said outer and inner shells and lid entirely fabricated from fire resistant ceramic fibers including mineral wool fibers, glass fibers and the like bonded to each other by an inorganic bond or charrable organic bond forming a porous insulating yet mechanically strong structure; e) said outer shell covered with a stainless steel sheath to prevent entry of hot gases from the flame into the porosities of the bonded ceramic fiber outer shell; f) the outer surface of said inner shell covered with an infrared reflecting metallic sheet to reduce the amount of heat received from the inner surface of said outer shell thereby reducing the heating rate of the inner shell; and g) said interior surface of said inner shell having an encapsulated ceramic porous body filled with molten and subsequently solidified phase change material, melting at a temperature lower than the degradation temperature of the valuable photographs or documents contained within said lightweight portable fire resistant containment system; whereby the lightweight portable fire resistant containment system sustains exposure to fire for up to 30 minutes typically having flame temperatures below 2000° F., while the contents there within are protected by reducing thermal exposure to a temperature significantly less than the 400° F. ignition temperature of paper.
