In one or more arrangements, a system is presented for preventing the spread of fire through a conveyor opening in a fire wall. In one or more arrangements, a fire door system is connected to the fire wall and/or conveyor proximate to the conveyor opening. The fire door system includes a door assembly, a door frame assembly, and an actuator. The door frame assembly is connected to the fire wall, covers portions of the opening below the conveyor and between belts of the conveyor, and forms a door opening above the conveyor. The door assembly is configured to move between a closed position, where door assembly covers the door opening, and an open position, where the door assembly at least partially uncovers the door opening. The actuator is configured to cause the door to be moved to the closed position in response to fire.

A firestop device includes a collar to be mounted to a surface at wall penetration of a plastic pipe. The collar includes a first collar half and a second collar half, having corresponding end portions which are connected to each other. A fire resistant foldable cap is circumferentially connected to the collar for closing off the penetration location when the pipe is collapsed. In case of a fire an actuation assembly moves the fire resistant foldable cap over the penetration location to close it off. The collar is a fold-out collar in which said corresponding ends of the first and second collar halves are hingedly connected to each other to be moveable from a folded state, in which the second collar half substantially overlaps the first collar half, to a folded out state, in which the first collar half and the second collar half form a ring shaped collar.

A firebreak device configured to arrest a flow of medical gas capable of combustion or of supporting combustion, said device comprising: a housing having a body portion, an inlet and an outlet, said inlet and outlet being linked by a conduit; a valve assembly located within said body portion, said valve assembly being movable between an open position, in which gas can flow between said inlet and outlet along said conduit, and a closed position in which gas flow between said inlet and said outlet is arrested; a biasing assembly (340) arranged within said body portion to move said valve assembly into said closed position; and a heat activatable stop (350) located between said biasing assembly and said outlet to hold said valve assembly in said open position against said biasing assembly, and adapted to release said valve assembly to allow said biasing assembly to move said valve assembly to said closed position at an activation temperature, to close flow of gas through the device if said heat activatable stop is activated, wherein: said heat activatable stop is arranged to prevent obstruction of said flow of gas adjacent an inner surface of said device.

A freight container (1) has a frame to which a bottom (2), a roof (3), and sides (5-7) are attached, one side having a door opening closeable by a folding door (12) made of flexible, fire resistant material. The door (12) is supported from runners (13) moveable along a rail (14) combined with a top member (9) of a frame delimiting the door opening. A gap (15) is formed between the top frame member (9) and the top of the door (12) in its closed condition. The top member (9) is provided with a depending support (16) having a surface facing the inside of the door (12) and having attached thereto a strip of heat intumescent material (20). A flow passage (18) is formed between the strip (20) and the door (12) for gasses attempting to escape from the container through the gap (15) in a fire inside the container. The heat intumescent material (20) is arranged to swell and close the flow passage (18) when subjected to hot gasses from the fire inside the container.

Self-closing vent assemblies configured to provide ventilation during normal ambient conditions and to close during a fire are provided. In one embodiment, the self-closing vent assembly includes a base vent plate having a plurality of apertures and a floating vent plate having a plurality of apertures offset from the apertures in the base vent plate. The floating vent plate is configured to move between a first position spaced apart by a distance from the base vent plate and a second position abutting the base vent plate.
