FIXED SYSTEMS OF SCUMS

	The extinction systems by means of foam ,  the   same   as    the    systems   of sprayers,  are   fixed  systems.    They are used for fires of solid materials and liquids and, with  certain  restrictions, in   fires  of gassy  materials.   To  generate  the foam, the   current    of   water   lapses    through different    teams     where      she     mixes appropriately   with   the   substance   that generates the foam, the espumógeno.       The  mixture  of  water  and  concentrated foam is,  almost always,  mixed  later with air.
Application examples:         Plants of production and of repair, storage plants in tanks,  refineries,   airports,   laboratories, chemical warehouses, garages, etc...
