🔍 Key Concepts

• Identify what each symbol 1, 53, and 55 represents on a standard SOLAS fire control plan legend (not just its shape, but the actual piece of equipment). • Think about which of those pieces of equipment the regulations require to be accessible and visible from outside accommodation or machinery spaces. • Recall that some symbols represent markings/signs rather than physical firefighting appliances.

💭 Think About

• First, match each number to its meaning using the illustration: what does symbol 1 indicate, what does 53 indicate, and what does 55 indicate? • For each of those real-world items, ask yourself: would this normally be installed inside a space, in a duct or bulkhead, or on an exterior deck or bulkhead? • Consider whether any of these items must be placed where shore-side fire teams can quickly find them without entering the vessel.

✅ Before You Answer

• Be sure you correctly identify symbol 1 – is it a fire appliance, or a location of documents/plan? • Double‑check whether symbol 55 is a device fitted in ventilation/structure or a portable unit that you would see on deck. • Verify if symbol 53 represents something that must be located at or near an external escape/embarkation or fire-fighting access point.
