🔍 Key Concepts

• Review what types of firefighting equipment are required at or near the machinery space / engine room entrances under SOLAS and Fire Control Plans. • Understand the difference between remote controls/actuation points (e.g., for CO₂ or other fixed systems) and the storage location of the agent cylinders themselves. • Match each numbered symbol (12, 24, 43, 57) with its exact meaning using the Fire Control Plan legend shown in the illustration.

💭 Think About

• For each numbered symbol, ask yourself: "Is this something that must be right at the engine room access so it can be used or operated quickly in an emergency?" • Consider which item, if placed immediately outside the engine room, could pose an additional hazard or is normally kept in a dedicated space instead of at the doorway. • Think about which symbols represent portable/operating devices versus bulk storage of extinguishing medium.

✅ Before You Answer

• Positively identify what symbol 12 stands for, and whether that item is normally at the engine room entrance. • Confirm that symbol 24 is linked to operating or control gear for a fixed system rather than the cylinders themselves. • Check whether symbol 43 or symbol 57 depicts the actual storage bank of extinguishing cylinders, which would usually be located in a separate, protected room rather than immediately outside the engine room.
