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 mining operations,
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). Benifits: High Expansion foam provides superior fire suppression and vapor barrier against a
broad range of materials.
