Extinguishing fire type “A” fires of solid flammable materials (fires during which heated particles of wood, paper, straw, textile and coal are created etc.)
Extinguishing fire type “B” flammable liquid fires (fires without heated particles, gasoline, oil, grease, lacquer, pitch, tar, etc.
Extinguishing fire from buildings in urban areas, military barracks, storages, chemical industry and industry for oil refineries.
Vehicles, with bigger amount of foam, are extinguishing fire in industrial areas individually, using hydrant pipeline.
In fire fighting installation mixer for water and foam is built-in, as well as port for foam extracting outside the vehicle.
When foam is added, as extinguishing fluid are used:
light foam: - limited adjustable extinguishing substance for fire type “A”;
adjustable extinguishing substance for fire type “B” - flammable liquid fires (fires without heated particles, gasoline, oil, grease, lacquer, pitch, tar, etc., and type “E” - fires on equipment and installations under voltage, electro engine, transformers, generating stations and etc.);
heavy foam: - limited adjustable extinguishing substance for fire type “A”;
- adjustable extinguishing substance for fire type “B” Carrying capacity of the chassis and propulsion capacity of the engine are things which define superstructure of firefighting vehicle: single graded or more graded fire fighting centrifugal pumps can bee install capacitate from 1600 to 6000 l/min under 8 bar pressure, and 400 l/min under 40 bar pressure and soaking altitude 7,5m.
water tank volume is from 3000 to 14000 l.
foam tank volume is from 200 to 9000l.
water/foam jet capacity of 1200 to 4500 l/min.
it is standard for all types of vehicles to have the vacuum water/foam mixers installed as well as the emergency winches and cabinet got the corresponding equipment with the Al-roll door, for fire extinguishing and protection of the firefighters.
