Certain aspects relate to an apparatus for fire protection to a peak of a roof of a structure including a fire-retardant conduit mounted to the peak of the roof. The fire-retardant conduit includes a channel having sidewalls, each sidewall including a top portion having a lip; a channel windbreak configured to cover the channel and the lip of the channel; and a fire-retardant source pipe coupling the fire-retardant conduit to a fire-retardant source to supply fire-retardant into the channel.

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.

The present invention relates to an in-building access path installation type smoke control system. An in-building access path installation type smoke control system is openably and closably installed in an in-building access path and includes a door casing having an intake port and a discharge port, a door nozzle installed in the door casing and configured to spray water supplied from the outside, and a main door body including a negative pressure inducer configured to allow water sprayed from the door nozzle to pass therethrough, generate negative pressure on the basis of the Venturi effect while the water passes therethrough, suck gas at the periphery of the door casing through the intake port, mix the sucked gas with water, and move the gas mixed with the water downward toward the discharge port.

A safety process for recycling components of a confined space metal container reducing sparking, significantly mitigating worker exposure to fires by forming a first safety water blanket in first compartment, cutting a first top off, cutting off a first side, and a second side if needed. Next, pumping the first safety water blanket into a second compartment of the confined space metal container then cutting first piping out of the first compartment, and removing to a second containment area. Excavating equipment is used to remove portions of hydrocarbons from the first compartment and loading the hydrocarbons for transport; then cutting a bottom off the first compartment, and lifting the bottom onto the second containment area and cutting the bottom into preset mill sizes for recycling. Repeating the steps for additional components.

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.
