HI-FOG® - Protecting Rolling Stock 1

What is Water-Mist ?

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 HI-FOG®?
Basic principle

is sprayed
water by means high pressure through special nozzles
of

creating HI-FOG® water mist


HI-FOG Fundamental principle

DECREASING THE DROPLET SIZE BY A FACTOR OF TEN

Increases the number of droplets by a factor of thousand

 Increases the surface area by a factor of ten

 Increases evaporation rate by a factor of ten


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)


Discharge test – transformers 26 kV & 95 kV

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


Generic solutions: passengers areas

- Variable or fixed composition train
- Water mist system in passenger areas: 2
different solutions:
- Spray head system
- Pop out sprinkler

Main risk areas considered:
- Passenger areas, including
toilette and vestibules


Typical configurations

Nozzles or pop-out
sprinklers
Creating and discharging mist

Section valves
Addressing mist
Pressure units – MAU or HAU
Pressurizes water (local or centralized at train level)


Distributed layout (one system-one car)

Vertical or horizontal
cylinder unit

Centralized layout (one system - more
cars)

Vertical or horizontal cylinder unit (available also in oveceiling version)


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)


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

• 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,..)

HI-FOG® for Rolling Stock: a variety of solutions

• Pressure accumulator units
• Actuation and section valves
• Specific HI-FOG® Nozzles and sprinklers
• Thin stainless steel, high pressure rated tubing


HI-FOG® for Rolling Stock: a variety of solutions
Some basic numbers

The system is tailored according to the single project and
technology used, but the most common solutions pass through the
following numbers:

• Discharge duration: between 3 and 15 minutes

• Quantity of water involved:between 50 and 250 liters of water

• Weight: between 300 and 1000 kilogram

• Accumulator unit dimensions: around 2 x 1.6 x 0.6 meters
