What differentiates a portable extinguisher from a fixed system?

A portable extinguisher is defined by its manual operation and the ability to be repositioned as needed. This means that individuals can take the extinguisher to the exact location of a fire, allowing for a flexible response to different fire scenarios. The design of portable extinguishers enables them to be carried and operated by one or two people without requiring a fixed installation, which makes them versatile for various firefighting circumstances on a ship or in a building.

Fixed systems, on the other hand, are typically installed in a designated location and are designed to operate automatically or be activated from a fixed point. They might be part of a larger fire suppression system and do not allow for movement to the fire, which limits their flexibility compared to a portable extinguisher.

Understanding the operational function and placement of these two types of firefighting equipment is crucial for effective fire response and for ensuring safety protocols are followed in emergencies.
