Abstract
Abstract A safe for storing and protecting the contents against high exterior temperatures in which the storage space is lined with foam insulation and a wax layer which melts to absorb heat energy. A drawer is slidably mounted for movement into and out of the space and sealed by an inner door with wide and narrow seals on the inner door periphery and door opening periphery embedding into each other. A pressure test hole extends between the storage space and the space outside the inner door for testing pressure. The inner door is locked by cams manually operated by a locking bar mounted on the outside of the inner door to engage locking posts within the cabinet. A hinged outer door provides an additional seal.
