🔍 Key Concepts

• Foam concentrate percentages used on ships (3% and 6%) • Difference between protein, mechanical, and aqueous film forming foams • Which foam is standard for flammable liquid (Class B) fires on modern vessels

💭 Think About

• Think about which foam type is specifically designed to form a sealing layer over hydrocarbon fuel spills. Which one creates a thin film on top of the fuel? • On most tankers and helicopter decks, what foam type and percentages are commonly required by modern regulations and ship designs? • Among the three named foams, which is most associated with fixed systems and portable foam equipment for fuel fires at sea?

✅ Before You Answer

• Verify which foam is described as forming an aqueous film over flammable liquids. • Check which foam type is widely used at helicopter decks and tank decks on ships, often supplied as 3% or 6%. • Confirm in your study material which foam concentrate type is commonly listed with both 3% and 6% mixing ratios.
