Expandol High Expansion (Hi-Ex)

Applications

Expandol is the ideal foam to use at

medium expansion at minor incidents such

as small hydrocarbon liquid spill fires where

close approach to the fire allows hand-held

apparatus to be used. It can also be used

in conjunction with fixed installations to

provide bund protection, where it can

achieve extinction of fires or suppression of

toxic vapour release after chemical spillage.

At medium and high expansion, Expandol

is used for the total flooding of fire areas

involving Class A and Class B fires: medium

expansion for small areas such as cellars

and basements of buildings, and high

expansion for large areas such as ships’

holds, machinery spaces, and LNG storage

tank bunds. Medium and high expansion

foams are most effective when dealing

with outbreaks of fire in inaccessible

locations, where direct application of

conventional agents such as water is

difficult or impossible due to smoke or

restricted access.
