A system includes a fire panel 12 having a loop driver. A combined detection and suppression loop 18 is connected to the loop driver. A plurality of fire detection devices 14 and a plurality of fire suppression devices 19 are coupled to the detection and suppression loop 18. The fire suppression devices 19 includes multiple sprinkler devices 19, each of the sprinkler devices 10 including a sprinkler bulb 100 and a circuit 120. The circuit 120 of the sprinkler device 10 is detectable via the fire panel 12 using the detection and suppression loop 18 in order to provide information from the sprinkler device 19 to the fire panel 12.

A safety system according to the present invention includes an on-ship system which is provided on a ship and a land system which is provided on land. The on-ship system and the land system each obtain, from a safety detection device and a safety maintenance device which are provided on a ship, data which has been detected by the safety detection device and a signal which indicates a state of the safety maintenance device, and, on the basis of the obtained data and signal, transmit to the safety maintenance device a control signal for controlling the safety maintenance device.

A method for pumping water on a naval vessel is disclosed, the method including but not limited to pumping fresh water from a fresh water reservoir into a fresh water flush tank; pumping salt water from a salt water reservoir into a fire water reservoir during fire operations; controlling a valve in liquid communication to alternately connect the fire water reservoir to the salt water reservoir to supply salt water to the fire water reservoir during fire operations and connecting the fire water reservoir to the fresh water flush to flush salt water from the fire water reservoir after fire water operations. A system is disclosed for practicing the method.

An enhanced shipping container apparatus that maintains packages is described having integrated fire suppression. The apparatus has a container base supporting the packages, multiple container walls coupled to the container base, and a container top coupled to each of the container walls. A fire suppression panel is integrated as part of one or more of the walls and top portion, and has a support sheet of fire resistant material; an interior exposed sheet of temperature sensitive material; a sealed boundary connecting the support sheet and interior exposed sheet on peripheral edges (where the sealed boundary, support sheet and interior exposed sheet define a holding cavity), and integrated fire suppression material in the holding cavity. The temperature sensitive material of the interior exposed sheet releases the integrated fire suppressant material from within the holding cavity when the temperature sensitive material of the interior exposed sheet is exposed to a threshold temperature.
