Raised Floor Systems

Server Rooms require the ability to effectively distribute power to racks, data cables, and cooling (i.e. air, water, coolant). Therefore, Server Room designers need to consider how best to distribute these services throughout the server room while also considering how best to address future requirements such as growth, increased demand for data distribution, and technological advances in cooling approaches.

Server room raised floors are the hallmark of the high-availability enterprise data center, and with good reason. For many companies, the presentation of their server room is an important part of facility tours for key customers. Data centers and server rooms without raised floors are perceived as being incomplete or less than state of the art.

The raised floor systems within server rooms provide the following:
  • A distribution system for conditioned cold air
  • Tracks, conduits, and/or supports for data cabling
  • Conduits for power cabling
  • A copper ground grid for grounding of equipment
  • A location to run chilled water and/or other CRAC piping

A COMPARISON OF THE THREE MOST COMMON FIRE SUPPRESSION CLEAN AGENTS – INERT, NOVEC 1230, AND FM-200
When most people think about fire protection in a building, fire sprinkler systemsimmediately come to mind. Sprinkler systems have long been used to protect buildings and the people that use them. However, sprinkler systems are designed to protect the building, not its contents. And, in many settings, they can be a very costly form of fire protection because of the damage that water can do and the clean-up required after they are used. Clean agent fire suppression systems are an ideal supplement to sprinkler systems to protect any type of assets that could be damaged by water.
Clean agent fire suppression systems disperse an inert gas or halocarbon gases to suppress a fire in its incipient stage before reaching the flame/heat stage that would activate the fire sprinkler system. The clean agent systems do not create a health risk for people, they are highly effective, electrically non conducting and leave no residue upon evaporation.
While clean agent systems are rarely required by building or fire codes, businesses and other institutions and organizations are increasingly turning to clean agent fire suppression as a more effective way to protect assets such as:
  • Computer systems including servers, and other electrical components
  • Telecommunications systems
  • Record/file repositories and libraries – anything with paper that must be protected
  • Digital data repositories
  • Cultural assets such as historical buildings, museums, and artwork
  • Flammable liquid storage for which sprinkler systems may not provide proper protection
  • Subfloors with critical building infrastructure that can be damaged with exposure to water
  • Laboratory and medical equipment
The three most common clean agents on the market today are Inert gas (Inergen, Nitrogen, Argonite), Novec 1230, and FM-200, which has been a mainstay of fire suppression systems for more than 20 years. This article provides a comparison of these three popular clean agents to help you decide which might be best for your needs.

How Clean Agents Work

Novec 1230 and FM-200 are clean agent fire suppression compounds made of synthetic chemicals in liquid form and are converted to gas in the discharge process. Both work to extinguish fire and prevent re-ignition by removing the necessary elements of combustion – heat. Unlike Novec 1230 and FM-200, Inert is a gaseous clean agent made up of a mixture of various inert type gases. Inert gas systems work by reducing the oxygen in the space to below that required for combustion.
Clean agents are stored in cylinders and are discharged through a fixed piping system at concentrations calculated based on the area they are intended to protect. All three agents,Inert, Novec 1230, and FM-200 extinguish Class A, B, and C fires, are electrically non-conductive, and will not short-out electronic equipment or thermally shock delicate circuitry. The table below provides some general information for each clean agent.

Logistical Considerations

When choosing a clean agent fire suppression system, the logistics of the space you are trying to protect is an important consideration. All three of these systems store the clean agent in pressurized cylinders. But, the quantity of suppression agent they can hold depends on the type of agent they use.
Inerts are stored as a gas and discharge as a gas, which requires more agent than halocarbon clean agents, Inert systems will require more cylinders – and more space to store them in – than Novec 1230 and FM-200, which are stored as liquefied compressed gas. Inert gas systems, can be located further away the protected space due to the pressure of each cylinder. Novec 1230 and FM-200 generally must be within or close to the protected space.
In addition to the amount of space required, you also have to consider where that space has to be located relative to the area to be protected space. This is due to how the halocarbon agents converts the liquid into gas as it flows through the system.
With FM-200 and Novec systems, the clean agent is stored as compressed liquid inside the cylinder and is pressurized with dry nitrogen to push the clean agent through the piping system. It is the friction created as the liquid flows under pressure through the discharge piping that turns it into a gas. Compressed liquids don’t flow as well as inert gases, and the pressure at which they flow through the pipe is lower than that of inert gases. As a result, the length of the discharge piping for the FM-200 and Novec systems is more limited than that of the Inert gas systems.
In contrast, the higher pressure in inert gas systems through the discharge piping system and over greater distances. So, while the Inert gas systems requires more cylinders, they can be located further away from the room to be protected. Another advantage of the Inert gas system is that it can be used to protect multiple areas through the use of selector valves, which can also reduce the number of cylinders needed for multiple spaces.
The table below summarizes some of the key differences between these systems that should be considered when choosing a clean agent fire suppression system for your business.
 Inert Gas SystemsNovec 1230 and FM-200 Systems
Proximity of Cylinders to Protected SpaceCan be located further awayMust be located within or very near the space to be protected
Number of Cylinders
Requires more cylinders for the same area protected than Novec 1230 and FM-200 – more storage space but can protect more than one area using selector valvesRequires fewer cylinders for same amount of space to be protected – less storage space than Inert gas systems and also less piping required
Weight of CylindersPressure only, no need to weigh cylinders but pressure must be checked on each cylinder with a calibrated gaugeAgent containers weight and pressure must be checked. Could require removing containers and placing on scale
Ventilation RequirementsRoom pressure venting may be  requiredTypically no special ventilation required

Potential Health Effects of Clean Agents

The “clean” in fire suppression clean agents means that they are safe to use in an occupied area and contain no substances that are toxic to humans.
The likelihood of exposure to the clean agent in the fire suppression system is minimal if the proper warning and alarm systems are in place to give occupants sufficient time to evacuate. With ample training for personnel and understanding of how the clean agent systems operates, the risks are minimal.
But, even with clean agents, too much of a good thing can be dangerous. Novec 1230, FM-200 and Inert gas systems all have concentration limitations. Proper design flow calculations are necessary to ensure the amount of agent is discharged for the cubic volume will result in a safe concentration for whatever agent you’re using.
Testing and certification laboratories assign different types of values to indicate the relative safety of clean agents and to guide proper engineering of the systems that use them. The table below compares Inerts, FM-200, and Novec 1230 in the following terms:
  • Design Concentration – Concentration of agent in the protected space that are safe for occupied spaces to extinguish Class A, B or C type fires.
  • The No Observable Adverse Effects Level (NOAEL) – The highest concentration at which adverse toxilogical or psychological effect has been observed.
  • Safety Margin – The margin of safety for a clean agent is calculated based on the NOAEL and the use concentration. The less agent you have to use (design concentration) relative to the concentration at which adverse effects are observed
  • Lowest Observable Adverse Effect Level (LOEAL), The lowest concentration at which an adverse psychological or toxicological effects have been observed.

Use Concentration34.2-42%4.0-6.0%6.7-8.7%

Environmental Considerations

Historically, the main environmental concern with clean agent fire suppression systems has been their effect on the Earth’s ozone layer. When the problem of ozone depletion was discovered in 1985, the fire safety industry began looking for alternatives to the Halon-based compounds used in clean agent fire suppression systems at the time.
Halon is a Monobrotrifluoromethane with very high ozone depletion properties. Its production was banned in 1994 under the Clean Air Act. While it is still legal to purchase and use recycled Halon, eventually, the diminishing supply will require businesses with halon-based fire suppression systems to replace their Halon systems with systems that use readily available alternatives such as Inert gas, Novec 1230 and FM-200.
FM-200 – a hydrofluorocarbon (HFC) – was the first replacement for Halon that promised no impacts to the ozone layer. It is important to note that there are no regulations against using FM-200. It is still manufactured and widely used in clean agent fire suppression systems. However, the increasing concern over global warming has given rise to newer alternatives such as Novec 1230 – the first clean agent on the market to boast no impact to the ozone layer or global warming – and Inerts.

Clean Agent Fire Suppression Systems Maintenance

The NFPA 2001 Standard on Clean Agent Fire Extinguishing Systems requires that your system as a whole must be inspected annually. The cylinders must be checked for weight and/or pressure every six months to ensure they have the required quantity of clean agent and that they are properly pressurized.

FM200 Fire Suppression System

FM200 Fire Suppression System

FM200 Fire Suppression is a suitable agent for normally occupied spaces. FM200 fire suppression systems are commonly used in :-
  • DATA Centres
  • Comms Rooms.
  • Telecommunication Facilities
  • UPS Rooms
  • Medical Facilities

What is FM200 Fire Suppression

FM200 fire suppression is also known as HFC227ea. FM200 is a waterless fire protection system, it is discharged into the risk within 10 seconds and suppresses the fire immediately.

How safe is FM200

FM200 fire suppression is found as an active compound as a propellant in medical inhalers. This is goes without saying that FM200 gas is extremely safe for occupied spaces with the correct fire suppression design.

How does FM200 work

There is a common misconception that FM200 gas reduces oxygen this is not true! FM200 is a synthetic/chemical fire suppression gas and extinguishes a fire by removing the free radicals or heat elements from the fire triangle. (Oxygen, Heat and Fuel)

The typical concentration of an FM200 system is normally between 7.9% to 8.5%. This concentration is determined by the risk that is being protected and by the OEM (Original Equipment Manufacturers) and the ISO14520 standards for fire suppression systems.

What are the advantages of an FM200 fire suppression system

The main advantage of FM200 fire suppression, is the small amount of agent required to suppress a fire.  This means fewer cylinders, therefore less wasted space for storage of FM200 cylinders.

FM200 systems reach extinguishing levels in 10 seconds or less, stopping ordinary combustible, electrical, and flammable liquid fires before they cause significant damage. FM200 extinguishes the fire quickly, which means less damage, lower repair costs. Like any other fire suppression system, FM200 systems are designed with an extra margin of safety for people. Refilling FM200 is simple and cost effective, therefore, it also means less downtime and disruption to your business.

FM200 is classed as a clean agent which means that it is safe to use within occupied spaces. The safety of FM200 fire suppression environments is proven in over a decade of real-world experience and validated by extensive scientific studies. FM200 systems take up less storage space than most other fire suppressants.

In addition to the fire protection benefits of using FM200, the environment will benefit as well. FM200 fire suppressant does not deplete stratospheric ozone, and has minimal impact on the environment relative to the impact a catastrophic fire would have. FM200 fire suppression is a solution that is already working in more than 100 thousand applications, in more than 70 nations around the world.

Inergen System

Inergen System

Inergen System

Inergen System adalah sebuah system untuk pengendalian kebakaran api dalam ruangan yang menggunakan Gas yang terdiri dari 52% Nitrogen, 40% Argon, dan 8% Karbon Dioksida. Inergen system memiliki keunggulan karena bersih / non toxin dan tidak meninggalkan residu saat aktif. Gas ini tidak mengandung Halocarbon, sehingga tidak memiliki potensi untuk penipisan lapisan Ozon dalam atmosfir. Gas pada Inergen system digunakan pada konsentrasi 35-50% untuk menekan oksigen yang ada pada area kebakaran. Seperti yang kita ketahui, ada 3 faktor yang bisa menjadi pemicu untuk awal terjadinya api. Yaitu bahan bakar, suhu yang panas, dan oksigen. Inergen system mendorong oksigen pada area kebakaran sehingga api dapat mudah dipadamkan dan mencegah api kembali menyala.

Inergen System Aman

Walaupun mendorong oksigen, inergen system tetap aman untuk manusia. Setelah terjadi kebakaran sebaiknya segera lakukan evakuasi semua orang yang berada di area tersebut. Hal ini untuk mencegah orang tersebut kekurangan oksigen saat inergen system bekerja untuk memadamkan api. Gas inergen menggantikan penggunaan CO2 (karbon dioksida) sebagai aplikasi system pemadam kebakaran karena kemungkinan tersebut. Tubuh manusia akan beradaptasi dengan Gas Inergen sesaat setelah system aktif. Hal ini menimbulkan alat pernafasan manusia mengambil nafas lebih dalam daripada keadaan pada umumnya karena pasokan oksigen berkurang. Gas yang mengandung nitrogen dan argon ini memiliki densitas yang sama dengan atmosfir normal, Sehingga mengurangi resiko terjadi kebocoran pada tabung – tabung dalam inergen system.
Gas pada Inergen system terdiri dari komponen alami yang ada di udara. Komponen ini secara ilmiah melanjutkan siklus normal dalam bumi. Sehingga Inergen tidak menimbulkan dampak lingkungan. Berbeda dengan media gas untuk pemadam api lainnya seperti hallon yang dilarang peredaran di seluruh dunia karena memiliki potensi besar untuk merusak ozon bumi. Lapisan ozon adalah lapisan yang melindungi kulit manusia dari paparan sinar ultraviolet matahari secara langsung. Jika sinar ultraviolet ini mengenai kulit secara terus – menerus maka bisa berakibat menjadi kanker kulit. Inergen system menggunakan “single phase” selama proses discharge untuk penyimpanan silinder, distribusi sistem perpipaan, dan nozzle, sehingga menyederhanakan desain pipa dan desain perangkat lunak pada komputer. Inergen system dijaga pada tekanan tinggi (200) sehingga memungkinkan untuk system perpipaan dirakit dalam jarak yang jauh.

Inergen System Teruji

Konsep pernafasan Inergen system telah disetujui oleh Occupational Health and Safety organisations Worldwide. Karena telah diuji pada orang – orang di Eropa dan Amerika serikat dan terbukti tidak beracun. Berbeda dengan Halocarbon (media gas lain) yang bisa mematikan pada konsentrasi tinggi dan beracun pada konsentrasi rendah. Maka tes halocarbon terbatas pada hewan di laboratorium. Simulasi pemadaman api menggunakan Inergen System secara lengkap bisa dilihat pada video berikut ini.

Which Gas Fire Suppression System is best? - FM200, Novec 1230 or Inergen?

Which Gas Fire Suppression System is best? - FM200, Novec 1230 or Inergen?

April 10, 2017

So, you have to choose a gas fire suppression system to protect against fire destroying valuable assets such as Computer Equipment, Document Vaults or Telecommuncations / Switch Gear. You have a choice between Chemical Fire Suppression Systems such as Novec 1230 or FM200 and Inert FIre Suppression Systems such as Inergen.


Is there a clear cut choice when it comes to Gas Fire Suppression? 

Well, no is the answer, but there are clear reasons to choose one over the other depending on the hazard size and location.

We will consider:
  • Environment
  • Safety
  • Speed of action
  • Storage Space
  • Cost

Environmental Considerations for Gas Fire Suppression Systems

This may not seem like an obvious first consideration when choosing a fire suppression agent, however there is some method to my madness. Read on to see why.

FM200 Fire Suppression

Firstly, FM200 is a HFC Gas that is now monitored under the Kyoto Protocal. Why? Well, it has a high Global Warming Potential and therefore has to be treated and monitored accordingly.
Any engineer working on an FM200 fire suppression system, even for maintenance purposes, has to be trained and certified in F-Gases.
The disposal of FM200 can only be carried out by licenced companies. All this additional licencing puts additional responsibilities and expense on the end user, who are often not aware of their repsonsibilities around this gas. 

So why is FM200 still chosen as a fire suppression agent? FM200 is more cost effective when its maintenance and disposal costs are left out of the equation. However, if the cost of the system is considered over its lifetime and subsequent disposal, then the obvious decision is to consider a different agent.



Novec 1230 Fire Suppression

Novec 1230 fire suppression agent is a relatively recent addition to the fire suppression industry. Manufactured by 3M, Novec 1230 comes with a 20 year "Blue Sky Warranty", guaranteeing its "Green" credentials. 
Choosing Novec 1230 over FM200 is the smarter choice and from here in this article, we shall consider only Novec 1230 and Inergen for that reason.

INERGEN 

INERGEN fire suppression agent is a mixture of three naturally occurring gases: nitrogen, argon and carbon dioxide. As INERGEN agent is derived from gases present in the earth’s atmosphere, it exhibits no ozone depleting potential, does not contribute to global warming, nor does it contribute unique chemical species with extended atmospheric lifetimes. Because INERGEN agent is composed of atmospheric gases, it does not pose the problems of toxicity associated with some of the chemically derived agents. 

So that is clear cut. Inergen is the cleanest of the fire suppression agents then. But wait......There is a far higher volume of Inergen required to cover the same hazard as Novec 1230 and it is stored at far higher pressures than Novec 1230. 

Inergen requires more steel to make the high-pressured steel cylinders for its storage. Therefore Inergen requires more energy for its manufacture, storage and transportation when compared to Novec 1230 systems.

Perhaps not as clear as it might first appear. However as far as the agent itself goes, Inergen is clean and therefore we will consider it further.



Environmental Winner? Inergen and Novec 1230 remain as sound choices.


Safety Considerations

Human Safety

When considering the safety of people that may be inside the hazard area, we shall look at the safety margin at the concentration levels of gas under the EN15004 Fixed Fire Suppression Standard.

Novec 1230 Fire Suppression Agent

For Surface Class A hazards, the concentration level for Novec 1230 required under EN15004 is 5.3%. The concentraiton level for Novec 1230, above which adverse effects can be observed in humans is 10%.

Safety margin = 88.7%

INERGEN Fire Suppression Agent

For Surface Class A hazards, the concentration level for INERGEN required under EN15004 is 39.9%. The concentraiton level for INERGEN, above which adverse effects can be observed in humans is 43%.

Safety margin = 7.7%


Operating and Storage Pressure

Novec 1230
25 Bar

Inergen
200 - 300 Bar

The amount of pressure relief venting required to ensure there is no damage to property in the event of a discharge will of course be higher with Inergen than Novec 1230.

Higher pipe pressures in the event of a discharge and cylinder storage pressures should also be considered in occupied environments such as office comms rooms or document vaults.
While cylinders are securely fastened to anchor points, inevitably fire suppression cylinders are removed and replaced in the event of discharge and when pressure testing is required.


Safest System for Humans and Property? Novec 1230



Speed of action

Novec 1230

Novec 1230 system are designed to fully discharge in 10 seconds. They act on fire by removing heat quickly, thus extinguishing the fire.

INERGEN

INERGEN systems are designed to discharge fully in 60 seconds. They act on fire by reducing the oxygen levels in the hazard enclosure, starving fire of one of its essential ingredients.

Fastest Agent? Novec 1230


Storage Space

The simple graphic below details the storage space required for each system under discussion.

The graphic below is based on the cylidner requirements for a 200m3 Class A Hazard


Winner based on Footprint? Novec 1230


Cost Factors

So far it seems that Novec 1230 is the obvious choice when it comes to the Environment, Human safety, Speed of action and Storage Space.

Why would any consultant or end user decide that INERGEN was the better choice over Novec 1230?

Answer: As the Hazard size increases, INERGEN starts to become more attractive from a cost perspective. In addition, it is possible to cover multiple hazards from one cylinder bank. 

INERGEN Cylinders can be stored at a far greater distance from the hazard than Novec 1230. 

Most Cost Effective System? Depends on Hazard Size and number of hazards in one location.
