What classification is used for light traps, door operating switches, and control circuits on a ship?

Light traps, door operating switches, and control circuits on a ship are typically classified under light security systems. This classification encompasses various safety and security functions related to lighting and operational controls that contribute to the overall safety and awareness aboard a vessel.

Light security plays a critical role in ensuring that areas remain illuminated for visibility and safety, and it includes controls that manage lighting in response to specific operational needs. For example, light traps can help manage unwanted light or ensure that emergency lighting is operational when needed. Similarly, door operating switches are part of the lighting security system, facilitating safe access and egress in different parts of the ship.

The contexts provided by other classifications do not fully encompass the purpose of these systems. Fire safety focuses more on fire prevention and response measures, electrical management pertains to the broader oversight of electrical systems rather than specific control functions, and operational efficiency relates more to the effectiveness of the overall operations rather than safety and security functions directly associated with lighting and door control.
