EXTINGUISHING AGENTS
Volume of the room or area
Cause/ Nature of the fire
Contents of area (Flammable objects or materials)
The number of occupants of area
Some agents like Halon 1301 (banned in Montreal Protocol) are toxic to humans,have adverse effects on the Ozone layer and leave residues that are damagingto equipment and machinery. Also, conformity with international safetystandards like the Montreal Protocol, NFPA 2001 and ISO 14520 have to bemade, and taken into consideration before an appropriate agent can be chosen.
Extinguishing Agents are the gases used to put out fires. Specific agents will berequired for specific hazards, and in order for it to be completely effectiveextinguishing agent must-
cause minimal or no damage to any equipment within the hazard area
not have any ill effects on personnel
put out the fire in a minimal amount of time (10 seconds)The extinguishing agent depending on the following variables:

EXTINGUISHING AGENTS
There are 3 Agents that conform to International Fire Safety Standards and that have beenfound to be the best extinguishants, they are;
FM 200
Developed as a Halon replacement, it is the most human friendly clean agent fireprotection for critical facilities. We have designed many systems with FM 200 and our partnersChemetron have developed an innovative Flow Calculation Software Program to aid us indesigning systems for all applications.
Argonite
Argonite is an inert gas that extinguishes fires based on the principle of oxygen depletion. Itis environmentally acceptable with Zero Ozone Depleting Potential and Zero Global WarmingPotential. There is no residue after discharge and thus not a danger to protectedequipment.
Water Mist
Natural, non-toxic and efficient this risk specific agent is a fine spray mist that offerseffective protection without the deluge and damage of traditional water based systems.

ARGONITE
ARGONITE is an inert gas that extinguishes fire based on the principle of oxygen depletion. In a
closed space almost all fires are extinguished in less than 60 seconds when the oxygen
concentration falls below 15%. ARGONITE reduces the oxygen concentration to approximately
12.5%, an acceptable level for human exposure over short periods of time.
ARGONITE extinguishes fire by physically removing oxygen from the atmosphere. In occupied
areas, people can breathe ARGONITE at extinguishing concentrations without fear. There are no
toxicological factors associated with the use of ARGONITE and ARGONITE will not decompose or
produce any by-products when exposed to a flame from a fire condition. It is environmentally
neutral, having zero ozone depletion potential (ODP) and zero global warming potential (GWP).

WHY FM 200 IS THE BEST ALTERNATIVE TO HALON 1301
The FM-200 Fire Extinguishant was SPECIFICALLY developed as a replacement forHalon 1301 and like Halon 1301, FM-200:
Is delivered as a gas through a network ofpipes.
Has the same rapid discharge time.
Offers an improved safety profile.
Leaves you ready to start operations minutesafter the fire.
Depending upon your unique hazard requirements, retrofitting an existing Halon system mayrequire anywhere from minor modifications to installing a fully integrated FM-200 suppressionsystem.
Today more than ever, people around the world are concerned with the effects of humankind onour earth. FM-200 systems provide a cost effective solution to replacing ozone-depletingHalon1301 with a fast, safe, and effective fire-fighting agent.
This retrofit capability grows more important as governments around the worldincreasingly ban the sale and use of Halon.
Efficiently stores as a liquid requiring minimalfloor space.
Performs within the same enclosure design asHalon 1301.
Requires no expensive renovations to existingrooms.

ADVANTAGES OF FM 200 OVER OTHER AGENTS
The FM-200 fire extinguishing agent is suitable for protecting high-value and mission-critical assetsagainst most classifications of fire including;
Ordinary combustible materials, such as wood, cloth, paper, rubber, andmany plastics. These materials are often referred to as Class A fires.
Flammable and combustible liquids and gases such as gasoline, oil,lacquers, paints, mineral spirits, and alcohols. FM-200 extinguishingconcentrations for these fuels are specific and unique to each individualproduct.
Energized electrical equipment. FM-200 is non-conductive making it safefor use with live electrical equipment. Current international standards
recommend de-energizing high voltage circuits on agent discharge.
FM-200 has no Ozone Depletion Potential. Its ODP is zero. FM-200 has been found by leadingtoxicologists to be safe for use when people are present. Unlike Halon 1301, people can beexposed to normal extinguishing concentrations of FM 200 without any fear of health problems.

Michael Hammond Engineering Company LimitedThe Strength Behind Every Great Organisation
ADVANTAGES OF FM 200 OVER OTHER AGENTS
FM 200 was designed as replacement for Halon systems, therefore keeping installation costs down, asFM 200 systems can easily be incorporated in existing Halon systems.
A key advantage for the FM-200 extinguishing agent system is the small cylinder storage spacerequirement. Floor space in critical sites is usually at a premium and, in some applications, such asRefineries, Offshore Oil Platforms, Marine Vessels and Small Electronic Facilities, SPACE, WEIGHT, andSTORAGE CAPABILITY IS EXTREMELY LIMITED.
FM-200 is an active fire-fighting agent, requiring only a small quantity of agent to effectively stop thefire. Most ordinary combustible fires are quickly extinguished with concentrations of only 7% of thegas, by volume. Additionally, the FM-200 extinguishing agent is stored in the cylinders as a liquid.
Fact: no other commercially available fire suppression system works faster to extinguish fires (intimes of less than 10 seconds) than an FM-200 systems. In performance tests and real-world
applications across the globe, FM-200 fire suppressant has proven its effectiveness:
Extinguishes ordinary combustible, electrical, flammable liquid and gas fires
Stops fire without causing collateral damage to equipment, data or othervaluable items
Approved and accepted by governments, health and safety organizations, andperformance monitoring agencies around the world

ADVANTAGES OF FM 200 OVER OTHER AGENTS
This saves substantial storage space. Other gaseous fire suppression solutions require much higherdesign concentrations, up to 40% by volume. Some agents, such as Argonite, cannot be effectivelystored as a liquid. These agents are stored as high pressure compressed gases and can require upto seven times the storage space of an FM-200 system.

UNSEEN DANGERS
FM 200 has no hazardous physio-chemical properties or health effects and it meetsall criteria laid down by Chemical (Hazard Information and Packaging) Regulations1993.
Unlike Halon 1301, FM 200 has no long term physiological effects on the occupants of theprotected area, during and after flooding.
Occupants who inhale FM 200 will only need to be brought into fresh air, unlike exposure toHalon 1301, which requires special medical attention to ventilate the lungs.
Eye contact with FM 200 requires the eyes to be simply rinsed with water for 10 15 minutes,and because there in no chlorine in FM 200 there is no pain associated with exposure to it.
A combination of soap and water is all that is needed if FM 200 comes in contact with the skin.
The chemical properties of Halon 1301, make exposure to it dangerous if inhaled for prolongedperiods occupants will lose consciousness due to asphyxiation (suffocation), experience skinirritations, and severe pain in the eyes.

ADVANTAGES OF FM 200 OVER OTHER AGENTS
In tests the acute toxity of Fm 200 has been evaluated and approved by the United States ProtectionAgency, as a total flooding agent in occupied spaces.
FM 200 is clean, it leaves no residue thereby cutting down after fire cleanup costs and keepsdown time to minimum. Most materials such as steel, stainless steel, aluminum, brass and othermetals as well as plastics, rubber and electronic components are unaffected by exposure to FM

DETECTION AND SUPPRESSION HARDWARE
Any efficient Fire Detection and Suppression System depends not only on theExtinguishing Agent but also on the right combination of Fire panels, Smoke or HeatDetectors, Fire Sensors and Accessories.
Alerting personnel in the event of a fire is also important and is a mandatory statutein the industries safety standards, hence the need for Strobes, Sirens and Alarmbells; these as well as strategically placed Manual Extinguishers, Fire Axes andFluorescent signs are what make up a COMPREHENSIVE FIRE PROTECTIONSYSTEM.
The smaller the time interval the better, that is why we stock only the most effective,minimal error sensors and detectors available in the industry.
These are the controls of the system and in essence they are the brains while theagent is the brawn behind the system. The time interval between the start of the fireand the detection of the fire will determine how fast the fire can be extinguished andhow much equipment (if any) will be destroyed before the fire is put out.

FM 200 INSTALLLATIONS
For an FM 200 to be comprehensively effective a thorough test for leakages known asan ENCLOSURE INTEGRITY TEST must be carried out. It is this that will determine if,when the FM 200 is released, it will either escape through minute holes in the wall,open or cracked windows, gaps in raised floor or false ceiling installations or will
perform its function and extinguish the fire within the design time.
In the late 1980's enclosure integrity testing became the standard acceptanceprocedure for approving new clean agent installations in lieu of a discharge test..NFPA 2001 declares, "a discharge test is generally not recommended" andestablishes a complete procedure for non-discharge approval testing in Appendix Cof the standard.
The enclosure-testing requirement is to locate any significant air leaks that mightresult in a failure of the enclosure to hold the agent concentration for the requiredamount of time. One benefit of room integrity testing is the ease of periodic re-testing to determine if adverse changes have occurred in the protected space, acommon occurrence particularly in electronic and data facilities. Periodic testing canbe carried out at your request

It is only after an ENCLOSURE INTEGRITY TEST that theamount of FM 200 needed to protect an area can truly bedetermined.
Also periodical tests must be carried out to determinewhether any changes may have occurred, that would affect
the extinguishing capabilities of the FM 200 system.
The FM 200 design engineers must be consulted about anyrenovations about to be made within a protected area, thiswill enable them to adapt the FM 200 system to suit theneeds of the renovated area, after appropriate integritytests have been carried out.
