Fire extinguisher of hard foam fire
fighting-30-Fast-hardening Foam (FHFF-30-FHF)
FHFF-30-FHF is intended
for
extinguishing fires Class A (solid combustible materials), as well as
for extinguishing and isolation of forest ground fires by creating
fire-resistant barrier strips;
for
protection of building metal structures (racks, beams) during a fire
from the effects of a flame;
for
thermal protection (shielding) during emergency spillage of metals
melts, for example copper;
to
protect the atmosphere of the environment in case of emergency outflow
of hazardous chemical vapors by creating a protective foam layer on
their surface.
The
main
parts of FHFF-30-FHF are a cylinder with a fire-extinguishing agent, a
tank (knapsack) with a hardener, a low expansion foam generator with an
ejector. FAF-30-FHF is supplied as a complete assembly unit and
doesn’t require additional installation of single components..
The extinguishing agent is Specialized Two-Component Composition for
Firefighting.

Application
– put
the
fire extinguisher on alert: pull the foam generator
out of the cylindrical holder, pull out the knapsack with the hardener,
open one of the two small covers on the top of the knapsack and put it
on the shoulder, straighten the hose of fire-extinguishing agent
supply, check the connection of the hardener supply hose with the
ejection device;
– open
a
lock (gun) by pressing the trigger (the trigger must be pressed
until the end of the foam supply);
– after stabilization of a foamy jet (after about 1 second)
open the supply tap of the hardener;
– to terminate the supply of foam – first close the
supply tap of the hardener and then release the trigger of the gun;
– close the supply tap of fire-extinguishing agent and the
lock-start gear;
– release the pressure in the fire-extinguishing agent supply
hose by pressing the trigger until the termination of solution supply
from the hose (2-3 seconds).
