An offshore oil and gas platform has equipment and piping associated with an oil and gas installation. A method for optimising fire protection for the platform includes arranging the platform to have an evacuation time of at most 15 minutes or less using one or more evacuation route(s) via a gangway or bridge allowing personnel to escape to a vessel or to another platform, determining a maximum evacuation time for the platform, assessing the risk to personnel using the evacuation route(s) in accordance with the determined maximum evacuation time in the event of a fire, and providing passive fire protection to equipment and/or piping on the platform in order to prevent escalation of the fire that would create a risk to personnel on the evacuation route(s) during the determined evacuation time.

A Christmas tree fire extinguishing system is provided, wherein an automatically initiated fire extinguishing agent is contained within a housing below the tree and a plurality of smoke and heat sensors communicate to a control unit. The control unit controls the trigger and interprets the sensor signals, while also sending signals to a communications system upon a fire event to notify the homeowner and/or the local fire authorities. In combination with the fire extinguishing agent, the system can monitor the tree and alert property authorities in the event of a fire to prevent home fires and major property damage. Also provided is an audible fire alert for those in the home, wherein a sound generator is energized if smoke or fire is detected to warn those in the immediate vicinity.

A building monitoring and control system in furtherance of engaging a detected and targeted threat to persons in or about the building is provided. The system is characterized by a threat detection module, a threat targeting module, a threat tracking module, and threat engaging assemblies. The threat detection module is provided in the form of a multi-modal sensor array or network system deployable or integral with a monitored building. Threat targeting and tracking modules are operatively linked to the threat detection module, and each other. Threat engaging assemblies, in the form of water cannons selectively deployable or integral with a monitored building, are operatively linked to at least the tracking module in furtherance of disrupting a located and trackable threat with water discharged from multiple water discharge nozzles of the water cannons.

A fire sprinkler emergency drain apparatus for conveying liquid from an open or leaking sprinkler head or leaking portion of a fire extinguishing system that includes a shallow mouth collection ring and drain line assembly having a collection ring of a size to surround a fire sprinkler head or a recessed opening in which a fire sprinkler head is positioned and a flexible drain line connected to the collection ring to convey liquid from the sprinkler head to a drain area, the drain line being mounted in a rolled configuration wherein the drain line is flattened in cross sectional configuration adjacent the collection ring and the shallow mouth collection ring and drain line assembly being supported by a handle adapted to be attached to a pole for use in elevating the shallow mouth collection ring and drain line assembly relative to a sprinkler head.

A connection device, a control box component, and a fracturing apparatus are provided. The connection device includes: a fixation rack, configured to be fixedly connected with a mounting base; a box connection mechanism, configured to be connected with the control box, and drive the control box to move at least from a first position to a second position relative to the fixation rack. In a case that the control box is located at the first position, the control box is located at a side of the transmission component and a distance between the control box and the transmission component is less than a predetermined distance, and during the control box being moved from the first position to the second position, the control box is away from the transmission component to form an operation space for the transmission component at the first position.

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 general-purpose engine control device capable of improving operation efficiency when transferring a liquid using a plurality of liquid pumps and containers. In a liquid transfer system that transfers water of a river to a container by way of a liquid pump, a container, a liquid pump, and a liquid pump in this order, an engine device has a communication interface for performing communication with another engine device, and transmits, after the driving of a liquid pump is started, start instruction information instructing the start of driving a liquid pump to an engine device installed next to the liquid pump on a downstream side in a water transferring direction on the basis of information indicating a driving record of the liquid pump. In an engine pump having received the start instruction information, the driving of the liquid pump is started.

The present invention provides stretchable laminates with a flat appearance on the visible surface. The laminates comprise a textile layer, a functional layer, and a plurality of elastic fibers. The plurality of elastic fibers are in a substantially parallel arrangement and the internal distance between adjacent fibers does not exceed the maximum fiber spacing, which depends on laminate thickness in a stretched state. Also provided are garments and footwear comprising the stretchable laminates and methods of producing the stretchable laminates.
