A water curtain head according to the present invention may comprise: a head body which is connected to a water supply pipe installed in an inner side of a building and has a water-releasing opening; and a deflector arranged adjacent to the water-releasing opening to allow water discharged by the water-releasing opening to pass therethrough. The deflector may comprise: a first spray nozzle formed on the front surface of the deflector to penetrate the front surface of the deflector; and a second spray nozzle formed to be recessed inward from a side surface of the deflector by a predetermined section.

A method of providing a deluge system (10) on a boom (12) such as a boom that is used to conduct well flaring operations at an end thereof. The deluge system comprises a base unit (30), a stanchion (20), and a nozzle apparatus (22); the method comprising attaching the deluge system to a burner boom with a walkway, such that there remains a width of at least 30 cm clear passage on the boom's walkway after the deluge system has been attached. This provides an escape and/or rescue route for personnel should a dangerous situation occur, such as uncontrolled fire or personnel falling overboard. In preferred embodiments, the deluge system is attached to the boom outboard of handrail supports (which includes on a single handrail). The deluge system may have its own mechanism e.g. a winch, for moving the stanchion from a stowed position to an operative position which allows a safe and more optimum positioning of the stanchion away from the well flaring operation, as herein described. In a preferred embodiment, the stanchion is provided as part of a moveable member which is rotationally attached to a connection mechanism of the base unit at a connection point spaced away from an end of the moveable member. This allows the moveable member to have a counter weight system and reduces the amount of force required to move the moveable member, avoiding mechanical constraints.

A fire-fighting device can cool a vertical wall where a horizontally-extending profiled element is disposed on the vertical wall. The fire-fighting device may comprise a guide plate that includes a first region arranged above the horizontally-extending profiled element, a second region arranged below the horizontally-extending profiled element, a third region arranged in a plane of the horizontally-extending profiled element and on a side of the horizontally-extending profiled element facing away from the vertical wall, and a fourth region in the second region. The guide plate may have a distance to the wall of 1 mm to 20 mm in the fourth region.

A multi-segmented, multi-plane, vertically deployable vapor and/or fire barrier assembly with a housing, a drive system, a folding barrier, a bottom plate, and motion sensors coupled to the bottom plate and coupled to a control system to detect operation and performance of the assembly, and related methods.

Embodiments relate to a screen-type fire suppression system for an electric vehicle, and more particularly, to a screen-type fire suppression system for an electric vehicle which, in the event of a fire in a parked electric vehicle, unfolds a screen on the sides of the electric vehicle to prevent the spread of the fire and simultaneously increase the concentration of water sprayed onto the electric vehicle, thereby maximizing fire suppression efficiency.
