Devices, methods, and systems for monitoring and controlling a smoke control system are described herein. One device includes a user interface configured to display a plurality of smoke control elements, wherein each respective one of the displayed smoke control elements represents a different component of a smoke control system of a facility, and receive, via one of the displayed smoke control elements, a selection of an action to be performed by the component of the smoke control system represented by that smoke control element, a memory, and a processor configured to execute executable instructions stored in the memory to cause the action to be performed by the component of the smoke control system represented by the smoke control element that received the selection of the action.

A safety cabinet includes an enclosure and at least one door to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a thermally-actuated damper that includes a body, a valve plate, and a pivot assembly. The valve plate is disposed within the passage of the body such that the valve plate is movable between an open position and a closed position. The pivot assembly includes a biasing system adapted to bias the valve plate to the closed position and a fusible link interconnected between the body and the biasing system to constrain the valve plate from moving from the open position to the closed position. The fusible link is configured to melt at a predetermined temperature to thereby allow the biasing system to move the valve plate to the closed position.

A ventilation closure system includes a damper, a shape memory alloy actuator, and a heating device. The shape memory alloy actuator is coupled to the damper. The shape memory alloy actuator has a first state in which the damper is positioned to permit airflow in the duct and has a second state in which the damper is positioned to obstruct the airflow in the duct. The shape memory alloy actuator is configured to change from the first state to the second state responsive to the shape memory alloy actuator attaining a first temperature responsive to heat released by an exothermic reaction in a compartment associated with the duct. The heating device is configured to heat the shape memory alloy actuator to maintain the damper in a position that obstructs the airflow in the duct.

A system for storing a hazardous product including a housing unit defining a product opening and a product door coupled to the housing unit adjacent to the product opening, wherein the product door is configured to form a seal with the housing unit about the product opening in response to a thermal event.

A containment system for a hazardous product includes a housing unit for storing the hazardous product. The housing unit includes sensors disposed throughout for detecting a thermal event. The system further includes an active fire suppression system configured to suppress the thermal event based on thermal event information received from the sensors. The system also includes a controller for processing signals from the sensors and activating the active fire suppression system, such as providing fire suppressants locally and/or globally or active venting. The system further includes a passive fire suppression system configured to suppress the thermal event using passive suppression without requiring activation from the controller, such as by coating surfaces of the system or using temperature sensitive venting or suppressant provision. The system may further include a training system to mimic the thermal event.

A system for storing a hazardous product including a housing unit having an interior volume and a door coupled to the housing unit configured to provide access to the interior volume. The system includes an electrical connection configured to transmit electricity into or out of the interior volume. The system further includes a ventilation system for directing gasses and heat produced during a thermal event out of the interior volume.

Embodiments of the present disclosure relate to an air handling unit having a housing that defines an air flow path therethrough, a heat exchanger disposed within the air flow path and configured to flow a working fluid therethrough, and a nozzle configured to deliver a fire suppression agent into the air flow path.

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.

A thermally actuated lock for an appliance incorporates a fusible material that holds a spring-loaded bolt in retraction. Temperatures that would indicate an appliance fire allow the bolt to extend between the housing and appliance door to lock the appliance door in a closed position.

This application relates to ventilation systems, more particularly to roof ventilation systems that help to protect buildings against fires. The roof vent has an ember impedance structure that impedes the entry of flames and embers or other floating burning materials while still permitting sufficient air flow to adequately ventilate a building. Several configurations of vents employing baffle members and fire-resistant mesh material are described, which can substantially prevent the ingress of floating embers and flames
