General Issues About Fire Protection&

HI-FOG Water Mist System

Definitions: LH = Light Hazard Occupancies OH = Ordinary Hazard Occupancies

OH1, OH2, OH3, OH4 In “Marioff language” LH basically refers to US standards and OH to European

standards

LH / OH occupancies are applications where the predominant hazard consists of Class A combustibles (solid) Hospitals Hotels Libraries Offices Residential buildings Schools Churches Data centres Etc. other similar spaces with similar type of fire load

GENERAL: Fire Protection

Three different fire fighting terms are used Fire Extinguishment

Complete elimination of any flaming or smouldering fire (so, that when left unprotected, no re-ignition takes place)

Fire Suppression

A sharp reduction in the heat release rate and prevention of re-growth of the fire

Fire Control

Limitation of fire growth and prevention of structural damages

Important to understand the difference between the terms so that no false expectations are given to the client

Fixed fire fighting systems are typically designed for suppression and control

Manual intervention always needed for complete extinguishment

GENERAL: Fire Protection

All the water mist systems are unique systems Hence the capability/performance of an individual system cannot be

generalised to cover any other system

The only way to evaluate different systems is through full scale fire testing System performance and all the important system design/installation

parameters are defined in application related full-scale fire tests NOTE! The testing must be done as per pre-determined acceptance

criteria released by a approval authority such as FM, VdS, IMO etc. Marioff has been the pioneer for developing the testing criteria

Basis for most international standards applied widely today

GENERAL: Water Mist Systems

VdS OH1 fire test-office application

Example: Full Scale Fire Test

Conventional sprinkler Water flux density: 5 l/min/m2

HI-FOG sprinkler (GPU) Water flux density: 0,6 l/min/m2

HI-FOG system performance has been proven to be better or equivalent to the conventional sprinkler system by full scale fire testing

HI-FOG vs. Traditional Sprinkler

A conventional sprinkler system with the flux density of 5 l/min/m2

HI-FOG is equivalent

With 90 - 70 % less water

Unbreakable chain reaction

HI-FOG® Provides efficient cooling

as well as radiant heat blocking

HI-FOG® Water mist evaporates

efficiently thus providing local inerting at the heart of the fire

Approvals and Standards

System approvals are gained through the appropriate approval procedure Full-scale fire testing Component testing Etc.

System approvals are a really important sales tool Proof of the system performance Marioff has the widest range of approved systems than any other water mist

manufacturer VdS Ordinary Hazard 1 (HI-FOG 2000) VdS Ordinary Hazard 1 (GPU) FM Light Hazard (HI-FOG 2000) FM Light Hazard (GPU) VdS Ordinary Hazard 2 for parking garages VdS Ordinary Hazard 3 FM for computer room subfloors (DAU) Etc. other more or less relevant approvals

Also the evidence provided by non-approval procedure related full-scale fire testing etc. is valuable information

General HI-FOG Sales and Design Issues

Efficient Cooling Enables good fire fighting

performance

Local inerting Removes oxygen from the heart of

the fire Enables good fire fighting

performance

Efficient radiant heat blocking Prevents the fire from spreading Makes evacuation & fire fighting

easier and safer Prevents structural etc. heat related

issues at the proximity of the fire Less activated sprinklers

Helps to minimize water damages

Small amounts of water Less water related damages Short down time for the building With traditional sprinkler water

damages often exceeds fire damages

Small water storage needed Small water feed needed

Smoke scrubbing capabilities Helps to minimise the smoke

damages

Fast activation Due to the low RTI value of the

sprinklers as well as the fairly low activation temperature

Smaller fire damages

Smaller smoke damages Rapid suppression and control of the

fire

Enclosure integrity not needed Good when fighting against gas

systems

Clean fire fighting agent i.e. potable water Environmentally friendly Safe for people

General Sales Arguments

Small piping Easy to route to difficult places and

do retrofits Easier to install Small trough holes

Pipes can be bent Easier installation Better aesthetic result

Stainless steel pipes No corrosion clean water Long lifetime

Cutting ring connections No welding needed Leak proof high pressure fitting

Compact pump units Does not consume valuable space

Self contained solutions E.g. good for cases where for

example electricity is not available

Several different kind of system variations Possible to optimize the system for

the customer / regulation needs

Gaseous penetration Water mist fills the space in 3D Enables good fire fighting

performance

No fire by-products Exists with some gas based systems

Less sprinklers overall Large coverage areas per sprinkler

General Sales Arguments…

Turn-key deliveries

Fewer headaches, lower costs

Traditional sprinkler and gas businesses are highly fragmented Consultants, component manufacturers, suppliers, installers... Who is responsible?

Marioff provides expert services for the whole system lifecycle System consultation and engineering Turnkey project management Production and installation Commissioning and training Maintenance, system upgrades and spare parts We ensure the quality of HI-FOG® systems and services

Understanding! The application i.e. the occupancy being protected Customer requirements / needs and converting them into HI-FOG reality

Area of Operation

= The maximum area over which it is assumed, for design purposes, that sprinklers will operate in a fire.

Area of Operation, hydraulically most unfavourable

= The location in a sprinkler array of an area of operation of specified shape at which the water supply pressure is the maximum needed to give the specified density
