High Expansion Foams High Expansion Foam Concentrates -
These agents are synthetic based and are suitable for use with low, medium or high expansion foam generating equipment. Normally used at a
proportioning rate between 1 and 3%, they are used in contained areas such as miningoperations, ship hold areas, etc. where volume fire control is required. A high expansion
generator can be used to fill the entire area with a large amount of very light, expanded foam bubbles, and depending upon the type of generator, ratios of up to 1,000 to 1 can be achieved. Fires
involving solid materials as well as flammable liquids can be controlled and extinguished. High expansion foam also has special advantages in dealing with spills of
Liquefied Natural Gas (LNG). |
