A fire hydrant tool for opening a fire hydrant in a controlled manner includes a cordless tool that has an output shaft and a trigger. A socket is attachable to the output shaft of the cordless tool and the socket has dimensions matching a top nut of a fire hydrant thereby facilitating the cordless tool to open the fire hydrant. A rod is attachable to the handle of the cordless tool thereby facilitating the rod to be gripped for manipulating the cordless tool. A ratchet driver is attached to the rod and the socket is attachable to the ratchet driver when the cordless tool has insufficient torque to loosen the top nut. A prying tool is coupled to the rod and the prying tool has a claw element and a hook element to grip an object for prying the object.

A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.

Provided is a technology for efficiently arranging equipment. A method of arranging equipment in a plant for processing a fluid includes: calculating a risk; obtained by multiplying a probability that flowing-out of a fluid requiring use of the equipment occurs by an impact degree of the flowing-out of the fluid; setting a distance of a range in which the equipment is arrangeable so that, when the calculated risks of a plurality of devices are compared with each other, the range in which the equipment is arrangeable is shorter for a device for which the risk is high, and the range is longer for a device for which the risk is low; and then determining a position to arrange the equipment based on positions at which the plurality of devices are arranged in the plant, and on the distance of the range in which the equipment is arrangeable.

Disclosed herein are a system, method, and apparatus for arresting flames in an air return line. The apparatus includes a flame barrier containing one or more metal mesh layers and configured to permit airflow there through while preventing flame break-through. The flame barrier can also have or be connected to one or more temperature or pressure sensors configured to detect blockage of airflow through the flame barrier and to detect damage to the flame barrier. The apparatus can also include additional temperature or pressure sensors for detecting the propagation of deflagration in the air return line.

A fire seal end cap including a cap portion and a plug portion, wherein the plug portion protrudes from the cap portion, and wherein the cap portion and the plug portion are formed from a fire-resistant material.

A fire suppression device including a nozzle body disposed about a central axis. The device also includes a bulb cage operatively coupled to the nozzle body. The device further includes an antenna integrally formed with at least one structural component of the fire suppression device.

Multiple robotic monitors are located in a hydrocarbon storage or transport facility. Each robotic monitor is communicably coupled to other robotic monitors and includes a heat sensor configured to detect heat emitted by a hydrocarbon tank of the hydrocarbon storage or transport facility. A controller is communicably coupled to the heat sensor and configured to generate a heat signature based on the heat detected by the heat sensor. A pump is communicably coupled to the controller and configured to exert pressure on a fire retardant, responsive to the generation of the heat signature by the controller. An outlet is mechanically coupled to the pump and configured to discharge the fire retardant at the hydrocarbon tank.
