What is <strong>Water</strong>-Mist ?<br />
Basic principle<br />
water<br />
is sprayed<br />
by means high pressure through special nozzles<br />
of<br />
creating HI-FOG ® water <strong>mist</strong><br />

What is <strong>Water</strong>-Mist ?<br />
Basic principle<br />
<strong>Water</strong>-<strong>mist</strong> is <strong>com</strong>posed of<br />
micro-droplets<br />
sprayed at<br />
high velocity<br />
to the seat of the fire<br />
HI-FOG® - Marioff – Railway Interior Expo 2009
What is <strong>Water</strong>-Mist ?<br />
Basic principle<br />
Fire is suppressed or extinguished by<br />
the <strong>mist</strong>’s large<br />
cooling surface<br />
which<br />
gives<br />
rapid vaporization<br />
oxygen depletion<br />
and<br />
maximum<br />
absorption of<br />
radiant heat<br />

HI-FOG¨ water <strong>mist</strong><br />
Provides efficient cooling as<br />
well as radiant heat blocking<br />
HI-FOG¨ water <strong>mist</strong><br />
Evaporates efficiently thus<br />
providing local inerting at the<br />
heart of the fire<br />

What is <strong>Water</strong>-Mist ?<br />
Basic principle applied to <strong>Rolling</strong> <strong>Stock</strong><br />
using water<br />
efficiently<br />
allows<br />
water<br />
consumption to<br />
be minimized<br />
<strong>for</strong><br />
weight/volume<br />
optimization<br />
(ca. 90% less than conventional sprinkler systems)<br />

Fire protection of <strong>Rolling</strong> <strong>Stock</strong><br />
HI-FOG ® <strong>Water</strong> Mist benefits are:<br />
Fast discharge via fire detection system (Conventional, HSSD…)<br />
Suppress, control and extinguishment of fire<br />
Cooling of the gases and smoke reduction to more tenable conditions<br />
<strong>for</strong> evacuation of passengers and access to fire brigades<br />
Minimise damage to equipment and infrastructure<br />
Using only environmental/human friendly means (air, nitrogen, water)<br />
MOST SUITABLE FIRE-FIGHTING SOLUTION FOR RAILWAYS<br />
