AFFF solution

AFFF solution

• A. 94% seawater 6% AFFF
• B. 100% seawater
• C. 50% seawater 50% AFFF
• D. 94% AFFF 6% seawater

Answer: (A)

AFFF works by diluting a foam concentrate in water to form a foam solution that blankets and cools the fire. The seawater acts as the carrier and cooling medium, while the AFFF supply provides the film-forming agents that create a stable foam layer on the fuel surface. The most effective and safe mix is a small amount of AFFF in a large amount of seawater, which lets the foam blanket form quickly and spread properly through the fire zone. Pure seawater would not produce foam, and a mixture with too much AFFF can fail to flow well and isn’t how the system is designed to deliver foam. Therefore, the intended solution is mostly seawater with a small concentration of AFFF.
