🔍 Key Concepts

• Review standard fire control plan symbols for escape routes versus piping systems • Notice the color and style of the arrow between frames 135 and 140 and compare it with the blue and red symbols elsewhere on the plan • Think about how a crew member would quickly locate escape routes on a posted plan during an emergency

💭 Think About

• How do the green arrows on this diagram differ from the blue vertical arrows and the red fire main symbols—what does each color usually indicate on safety plans? • If you were in the lower engine room and needed to evacuate, which symbols would guide your path, and which would guide you to firefighting equipment instead? • Does the arrow between frames 135 and 140 connect to doors, ladders, or piping, and what does that suggest about its purpose?

✅ Before You Answer

• Verify the color of the arrow between frames 135 and 140 and match it with the legend you know from standard fire control plans (escape vs fire main vs search patterns) • Check whether the arrow is aligned with a route through doors or ladders, rather than along a pipe run or CO₂ line • Confirm that nothing in the diagram suggests an organized search pattern, which is usually not shown the same way as permanent safety equipment.
