HI-FOG in general

HI-FOG main features

• Superior fire suppression performance

• Minimal water consumption

• Low ‘whole life’ and re-fill cost

• Flexible design

• Modular structure

• Easy to maintain

• Fast installation

Leading to:

• Less fire damage

• Less smoke damage

• Less water damage• Shorter ‘down-time’

• Improved safety • For personnel• For protected equipment• For the environment


HI-FOG in general

• High pressure water mist fire protection system • Class I water mist (NFPA 750) - Dv0.9 < 200 m

• Single fluid (H2O) or Twin fluid (H2O + N2) or (H2O + air)


Class A fires

• fire load - solid materials

• Conventional sprinklers

Class B fires

• fire load - liquids & gases

• Halon, CO2, Inert gases, foam and powder

HI-FOG - fundamental principles


Heat

HI-FOG extinguishment mechanisms:

UNBREAKABLE CHAIN REACTION

Oxygen

Fuel

How does it work?

• Oxygen depletion (local inerting)

• Radiant heat absorption

• Cooling


Cooling

• Ultra fine droplets create extensive cooling surface area

• Air entrainment into fire plume assists penetration of droplets to fire

• Cooling of the hot burning gases


• High mist density (large quantity of small droplets)

• Absorbs & scatters heat radiation - prevents fire spread

• Assists fire fighting and resque activity

Radiant heat absorption


• Small droplets turn to vapour faster than bigger droplets

• Water expands 1760 x when turning to vapour (>100°C)

• Vaporisation ‘blocks’ oxygen locally from fire source

Oxygen depletion (local inerting)


HI-FOG fire protection in Urban

Transportation


Urban mass transportation

Metros and city lines

• Located under the cities

• Tens of kilometres in different levels

• High traffic intensity

• Huge amount of daily passengers

Fire is causing problems with!

Operation of rescue service

Evacuation

Fire load


Risks on metros and city trains

• Causes of fire:

• Equipment failure

• Vandalism / Arson

• Neglect / Misuse

• Catalysts:

• High air flows in tunnels and around moving trains

• Combustible materials carried by passengers

• Combustible materials in operating systems (oil, grease, fuel)

• “Chimney effect” spreads smoke extremely rapidly at

underground stations

• Issues:

• Smoke generated by fire

• Heat generated by fire (convected and radiant)

• Evacuation of passengers and staff from underground


HI-FOG benefits on metros

HI-FOG objective• Fast discharge via fire detection system

• Fast activation also in sprinkler mode

• Control, suppress or extinguishment

• Cool down the gases and smoke reduction makes more tenable conditions for evacuation and access for fire brigades

• Minimise damage to equipment and infrastructure


HI-FOG benefits on metros

HI-FOG objectiveWhat added value water mist can offer?

• Small water flow is suitable for many areas where conventional would cause a flood

• Can be used in all spaces – replaces gas systems

• High voltage tests with HI-FOG

• Effective suppression reduce smoke accordingly

• Solving problems with ventilation and evacuation


HI-FOG for metro stations

Fire Protection based on different spaces

• Platforms

• Tracks under and

above trains

• Corridors

• Escalators

• Control rooms

• Service areas

• Sales kiosks

• Transformers

• El. switch gear rooms

• Cable tunnels


HI-FOG for transformers


HI-FOG for escalators

HI-FOG objective• Dry pipe system with small pipes: 16…25 mm

• Spray heads to cover high risk areas underneath stairs

• Each escalator has own section valve for operation

• Machinery space also to be protected

• Early alarm from aspirating fire detection

• Activation automatically or manually due to alarm

• Minimal water usage during activation



• Directed spray heads –to cover risk area

• Creates condition to escape in case of fire

train

platform



• Spray heads are pointing to the same direction

• Ensure a good penetration throughout a train length


HI-FOG systems for metros

HI-FOG units for metro stations

• Independent self-contained units – MAU or HAU (cylinder unit)• To be placed next to a protected space• One unit can protect several targets near by

• Centralised unit – GPU (gas driven)• Able to serve from further distance• Able to serve several areas• Able to operate without outsourced power

• Centralised unit – SPUD (diesel driven)• Able to operate without outsourced power• Able to serve several areas• For larger protected spaces

• Centralised unit – SPU (electric)• Able to serve several areas• For larger protected spaces


Metro facilities and systems

Latest developments in water mist systems


The case study – Madrid Metro

• Requirements

• Project description


A few facts

• Specially designed water mist fire protection for Madrid Metro’s

trains

• Firstly 80 trains were equipped with HI-FOG water mist system

• The following project was to cover 142 new trains including 684

carriages with water mist system


Requirements by Madrid Metro

• System should give good protection against fires in the passenger compartments of a metro vehicle

• System should be able to protect more than one carriage simultaneously

• System should be able to operate a minimum of 10 minutes in order to give passengers enough time for evacuation

• System should be able to control, suppress and even extinguish fires with a carriage’s doors open


Water mist system for metro trains

• One centralized unit per train to serve all the carriages

• Flexible high-pressure hoses between the carriages connects

the system piping

• Solenoid valves were used for discharge

• Train with 6 carriages 4 carriages discharged simultaneously



Centralised unit

Section valve



• Aspirating fire detection system

• Sensitive detection for early stage fire alarms

• Activation by driver or automatically (option)… or remotely from

central control station


System operation – passenger compartment


Fire test – passenger compartment


System operation – under carriage


Centralised water mist unit for trains

Summary

• High-pressure water mist suits well for several spaces in metro and underground stations

• Water mist is likely an only option to protect trains sufficiently

• Water mist provides good performance with small amount of water

• Marioff has a long track record of developed and installed water mist systems
