An offshore oil and gas platform 14, 16 has equipment and piping associated with an oil and gas installation. A method for optimising fire protection for the platform 14, 16 comprises: arranging the platform 14, 16 to have an evacuation time of at most 15 minutes or less using one or more evacuation route(s) via a gangway or bridge 136 allowing personnel to escape to a vessel or to another platform 14, 16; determining a maximum evacuation time for the platform 14, 16; 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 14, 16 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.

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.

Disclosed herein is an example method for expelling a fire suppressant from a container into a distribution manifold. The method includes generating a propellant gas that flows into the container via a first port of the container, thereby causing a pressure within the container to increase. The container includes the fire suppressant prior to the generation of the propellant gas. The method further includes, in response to the pressure within the container exceeding a threshold pressure, expelling the fire suppressant from a second port of the container into the distribution manifold. The generated propellant gas continues to flow into the container via the first port at least until substantially all of the fire suppressant included within the container prior to the generation of the propellant gas is expelled from the container via the second port. Example fire suppression systems are also disclosed herein.

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 test cell for an aircraft turbojet, wherein the test cell comprises a U-shaped configuration, with a passageway in the form of an elongated corridor, an inlet chimney, and an outlet chimney. The corridor includes a securing area with a securing arm for holding the turbojet during its test. The passageway furthermore reveals an upstream shutter and a downstream shutter, the two shutters including one pivoting flap or a series of pivoting flaps. In the event of a fire, the shutters close due to autonomous return means. Gravity allows the flap(s) to come down to the closed position and to confine the turbojet in order to rapidly stifle the fire.

A climate control system adapted for a room having a ceiling has a central unit mounted to the ceiling. The central unit has a rotary portion. A plurality of fan blades is carried by the rotary portion. The fan blades are adapted to direct air within the room by rotating clockwise and counter-clockwise. The fan blades have heating elements for producing heated air. The fan blades rotate to push heat downward away from the ceiling. The system has at least one nozzle carried by the central unit for generating mist from the water. The system has at least one sensor for controlling the system. Additional elements can include air purification, air conditioning, and dehumidification. A conduit extends from a central unit to a wall for routing air ducts, a water pipe, a drain tube for draining water, and power.
