Skip navigation links BFS 3460-08B-2 FIRE PROTECTION SYSTEMS (BFS3460-08B-2) - Essay Example High expansion foams acts the same but are typically used in holds of ships and basement room areas where access to fire and burning material is limited. It acts by halting convection and access to oxygen by steam displacement. This type of foam is used in controlling liquefied natural gas spill fires and helps in dispersing the resulting the vapor cloud. High expansion foams have very low water content making it suitable to use in settings where damage to equipment by water is highly probable. It is also this characteristic that results to a minimum amount of residue thus minimizing post fire clean-up requirements. The National Fire Protection Association has stipulated that this type of systems should completely fill and engulf an area where the fire is occurring thus making it suitable in settings where quick suppression is required. The high water content of low expansion foams makes it heavy and possible to be projected to burning material at safe distances. It also has a very high flow index and its wetting effect makes it more suitable in extinguishing fires in burning solid
