🔍 Key Concepts

• Fire detection zones and what they physically represent on a vessel • Difference between how big/where a fire is vs. how fast it’s growing vs. how hot/intense it is • How an automatic detection system actually senses and reports conditions

💭 Think About

• Ask yourself: If several separate detection zones are going into alarm, what does that tell you about where the fire may be, or how far it has reached? • Consider which of the options would normally require time-based trending or special sensors, rather than just a count of zones in alarm at one moment. • Think about what information the bridge crew can reasonably infer just by seeing Zone 3, 4, and 5 in alarm at the same time.

✅ Before You Answer

• Be clear on what a zone is: a defined area or compartment, not a measure of temperature or growth rate. • Decide whether a simple count of zones can directly tell you how fast the fire is changing, or just how many areas are affected. • Check which choice best matches the idea of extent of area affected rather than detailed fire behavior characteristics.
