Abstract
In the walls of a fire resistant enclosure such as a cabinet for storing heat sensitive, valuable goods or a room or shelter in a building in which persons can find refuge in the event of a fire, hollow bodies of large area contain substances which melt at a temperature which is still acceptable to the contents of the cabinet or physiologically acceptable to the persons in the room or shelter. The invention also provides various appliances for alleviating conditions in a said room or shelter, for providing a breathing air supply at an acceptable temperature for persons trapped therein and for facilitating the evacuation of persons therefrom, all such appliances involving the use of substances adapted to absorb heat from their environment by utilizing the latent heat of fusion of the substances.
