Fixed firefighting systems are designed to be permanently installed in designated areas where the risk of fire is higher, such as engine rooms, machinery spaces, and cargo holds. This characteristic is crucial because it allows the system to be readily available for immediate response in case of a fire, without the need for manual relocation. These systems, such as sprinkler systems or foam extinguishing systems, are engineered to provide consistent fire protection for the specific hazards present in their locations.

In contrast, portable extinguishing equipment is designed for movement and use in various locations, but fixed systems serve a dedicated purpose in high-risk areas. Manual activation is not a requirement for all fixed systems; many of them can operate automatically, contributing to their effectiveness in an emergency. While some fixed systems could indeed be used for other emergencies, their primary design and function are specifically for firefighting, emphasizing their critical role in fire safety aboard vessels.
