HI-FOG® - Protecting Rolling Stock 2
Water-Mist systems utilize clean water as fire-fighting agent.
Water is the oldest, the most widely used, and the most widely available fire
fighting agent in the world:
Non-toxic
Environmentally friendly
Has superior fire fighting capabilities in a wide range of applications
What is Water-Mist ?
HI-FOG® - Protecting Rolling Stock 3
What is HI-FOG®?
water high pressure special nozzles is sprayed
by means
of
through
creating HI-FOG® water mist
Basic principle
HI-FOG® - Protecting Rolling Stock 4
HI-FOG Fundamental principle
Increases the surface area by a factor of ten
DECREASING THE DROPLET SIZE BY A FACTOR OF TEN
Increases evaporation rate by a factor of ten
Increases the number of droplets by a factor of thousand

What about HI-FOG® water mist and electronics?
“None of the tests conducted indicated any significant increase in
hazard to the personnel in the vicinity of the charged plate due to
the presence of the water mist.” (Hughes Associates, 2004)

Fire protection of Rolling Stock • General description of the solution:
• The supression system is to control and suppress fires in different areas of the train: • Passanger areas (seating areas, toilets, vestibules, sleeping cars, restaurant cars) • Technical areas (engine and electric enclosures)
• The system in passenger areas might be, at train level, centralized or distributed:
• On fix configuration trains, it is preferred a centralized solution, with 1 or 2 water mist units connected to the entire pipe network and nozzles.
• On variable configuration trains, that adds or removes single coahes on a daily base, the system is normally distributed, with small but indipendent systems installed on every coach.
• The system in the technical areas is normally distributed, using water mist or other technologies to protect the single area
• NO ONE-FIT-ALL but TAILOR-MADE SOLUTION
HI-FOG® - Protecting Rolling Stock 13
Generic solutions: passengers areas
- Variable or fixed composition train
- Water mist system in passenger areas: 2
different solutions:
- Spray head system
- Pop out sprinkler
- Passenger areas, including
toilette and vestibules
Main risk areas considered:
HI-FOG® - Protecting Rolling Stock 14
Typical configurations
Section valves Addressing mist
Pressure units – MAU or HAU Pressurizes water (local or centralized at train level)
Nozzles or pop-out
sprinklers Creating and discharging mist
HI-FOG® - Protecting Rolling Stock 15
Distributed layout (one system-one car)
Vertical or horizontal
cylinder unit
HI-FOG® - Protecting Rolling Stock 16
Centralized layout (one system - more cars)
Vertical or horizontal cylinder unit (available also in oveceiling version)
HI-FOG® - Protecting Rolling Stock 17
Open nozzles deluge system
• System concept: • The detection system gives alarm and activate the unit and the section
valve/s of the alarmed zone/s
• The mist will discharge through the open nozzles of the specific zone
• Typical hardware composition: • MARIOFF MAU or HAU (accumulator pressure units), typically composed of a
50 l pressure cylinder + (2 or 3) 50 l water cylinders
• Main dry pipe along a single car or entire train, diameter 16-20 mm
• Zone system each half of a car + a nozzle(s) overlapping
• Each zone controlled by a machinery section valve

Zoned deluge system
• Advantages of overlapping zoned deluge solution:
• quick system operation
• quick cooling
• anti vandalism (not visible)
HI-FOG® - Protecting Rolling Stock 20
Pop out sprinkler system
• System concept: • The System will be pre-activated by detection system
• All the sprinkler bulb gages will pop out automatically by the pressure
• NO WATER DISCHARGE AT THIS POINT
• As the heat breaks the single bulb, the sprinkler starts discharge locally
• Typical hardware composition: • MARIOFF MAU or HAU (accumulator pressure units), typically composed of a 50 l
pressure cilynder + (2 or 3) 50 l water cylinders
• Main dry pipe along a single car or entire train, diameter 16-20 mm
• HI-FOG® pop-out sprinkler heads

Pop out sprinkler system
• Advantages of pop out sprinkler solution:
• avoids accidental discharges • local intervention, point by point • less invasive, more visibility • allows better evacuation of the car • intelligent use of water (smaller quantitites and longer
duration) • smaller piping, smaller pressure units • anti vandalism (not visible) • better suppression performance (higher pressure) • better fitting to separate enclosures ( toilettes,..)
