Introduction of Fuel System Icing Inhibitor will lower the JP-5 flash point by 4 degrees Fahrenheit and will also inhibit what?

• A. Growth of bacteria
• B. Corrosion in fuel lines
• C. Formation of varnish
• D. Water contamination

Answer: (A)

Fuel System Icing Inhibitor used with JP-5 provides two benefits: it lowers the point at which fuel vapors can ignite and it has antimicrobial properties that suppress microbial growth in the fuel system. The presence of moisture in tanks can support bacteria and other microorganisms, which form slime and biofilms that clog filters and fuel lines. The additive’s components help inhibit those bacteria, making the fuel system cleaner and easier to maintain. While corrosion control, varnish formation, and water management are important in fuel handling, the question highlights the antimicrobial effect provided by FSII, which is why growth of bacteria is the best answer.
