Many companies rely on sprinkler systems to protect buildings and occupants from fire, but what about your business? Could your business survive a fire and the collateral damage caused by water and associated clean up? What about your information systems and irreplaceable assets? The problem is sprinklers provide good fire protection, yet may destroy critical business systems and irreplaceable assets. Most companies need a balanced approach of sprinkler systems to protect building structures and Waterless Fire Protection systems to protect critical assets.
Based on comparison tests simulating fire sizes typical of those that occurs in data centers and telecommunications equipment. Compare the differences in speed of activation, fire size, and secondary damage. As you will see, relying on a sprinkler system for protection of electronic assets can be ineffective and costly.
Disaster recovery, if even possible, is expensive and time-consuming. Join the tens of thousands of organizations that have shifted their risk management strategy from disaster recovery to business continuity by using FM-200 Waterless Fire Protection systems to protect their critical assets.
Certain hazards within office, industrial, commercial and institutional facilities require special attention. These hazards include computer rooms, clean rooms, telephone switches, art and historical applications and any facility where water damage from sprinklers must be avoided at all costs. A variety of approaches and chemicals are available to provide a custom solution to your special hazard.
System types include:
Carbon dioxide |
- An electrically non-conductive agent is required
- Cleanup of other agents presents a problem
- Hazard obstructions require the use of a gaseous agent
- The hazard is normally occupied and requires a non-toxic agent
- Computer rooms
- Control rooms
- Tape storage rooms
- Critical file storage rooms
- Telecommunications facilities
- Clean rooms
- Electric switchgear
- Process equipment
- Engine test cells and other test bays
- Libraries, museums, art galleries, archives
HFC-227 (FM-200), chemically known as heptafluoropropane, is a fire suppression agent manufactured in the United States by Great Lakes Chemical (FM-200) and DuPont Corporation (HFC-227). FM-200 is a replacement agent for the ozone depleting Halon 1301 used extensively before 1994. Just as with Halon 1301, people can be exposed to normal extinguishing concentrations of FM-200 without any fear of health problems. FM-200 is a safe, no-residue protection for Class A, B and C type fires and has zero ozone depletion potential.
Often FM-200 systems are used to protect critical installations formerly protected by Halon 1301, some of these areas include:
- Data Processing Centers
- Telephone Switches
- Process Control Rooms
- Art and Historical Collections
- Facilities where water damage from sprinklers must be avoided at all costs
In a typical system the extinguishing agent is stored in cylinders or spheres. It is delivered to the hazard by a piping network and nozzles.
Vital to the functioning of the system is the fire detection and control network. Typically detectors sense the presence of smoke in the protected facility. The detection and control panel then sounds an alarm, performs pre-determined auxiliary functions and releases agent into the protected area.
At CASCO. our fire protection specialists are factory trained in the design of FM-200 fire suppression systems. Engineered drawings will be prepared using the latest versions of Auto Cad. You will be supplied hydraulic flow calculations and other engineering data detailing the expected performance of your FM-200 system.
Inergen is an environmentally friendly three dimensional fire suppression agent replacing Halon 1301. Critical facilities such as data processing rooms, telecommunications switching facilities, process control rooms, and others require a non-water based extinguishing agent that:
- Is electrically nonconductive
- Is safe for use in human occupied facilities
- Will not damage sensitive electronic equipment
- Has zero ozone depletion, zero global warming, and zero atmospheric lifetime
Inergen is a blend of three naturally occurring gases--Nitrogen, Argon, and Carbon Dioxide. The strategy of fire extinguishment employed by an Inergen system is like no other modern suppression system in use today. An Inergen system lowers the oxygen content of the protected area to a point sufficient to sustain human life, but insufficient to support combustion. It's that simple.
Because it's not a chemical agent, Inergen will not produce a heavy fog the way other extinguishing agents do, so escape routes remain visible.
The Inergen agent discharges through specially designed nozzles. These nozzles are fitted with discharge deflectors to minimize turbulence in the protected area.
FE-13 was originally developed by DuPont as a chemical refrigerant. Its molecules at the flame front absorb heat from a fire in much the same manner as a sponge absorbs liquid. In addition, FE-13 exhibits some ability to inhibit the chain of combustion in the manner of Halon 1301. For this reason the agent is a suitable Halon alternative.
At CASCO we design, install, and service Kidde FE-13 fire suppression systems. FE-13 offers you numerous features and advantages as a Halon alternative agent:
- Low boiling point and high vapor pressure make FE-13 effective down to -40°.
- NOAEL level of 30% makes the agent ideal for inerting occupied spaces.
- Contains no Chlorine or bromine and rated "acceptable" by the US Environmental Protection Agency for use without restrictions.
- Ozone depletion potential of zero
- Limited atmospheric lifetime
- Cost effective
Carbon dioxide is recommended for the protection of unoccupied facilities. CO2 is economical and can be designed as a local application or total flooding system.
At CASCO. we install Kidde, and Ansul carbon dioxide fire suppression systems. Carbon Dioxide (C02) gas has a high ratio of expansion which facilitates rapid discharge and allows for three dimensional penetration of the entire hazard area quickly. Carbon Dioxide extinguishes a fire by reducing the oxygen content of the protected area below the point where it can support combustion. Carbon Dioxide Fire extinguishing systems typically store the agent in one of two different ways, high pressure cylinders, or low pressure CO2 tanks.
When designed, engineered, and installed properly, Carbon Dioxide fire suppression systems will not damage sensitive electronic equipment. Carbon Dioxide has no residual clean-up associated with its use as a fire suppression agent. Carbon Dioxide fire extinguishing systems can be used to protect a wide variety of hazards, from delicate electronic equipment to high-voltage electrical equipment, all without causing damage to the equipment being protected.
Used on a wide variety of hazards throughout the world:
- Flammable liquid storage
- Printing presses
- Mixing Operations
- Spray Booths
- Industrial Ovens
- Dust Collectors
- Paint Lockers
- Marine Applications
A Carbon Dioxide Fire Suppression system consists of one or more banks of cylinder storage containers to supply the CO2 extinguishing agent. Flexible discharge bends, or hoses, connect the cylinders into a piping manifold. The manifold in turn distributes the agent into the piping network. Nozzles regulate the flow of CO2 into the protected area.
Before Carbon Dioxide is released into the protected facility, fire must be detected by a detection and control system. We use the Pegasus addressable control panel for Kidde systems and the Autopulse control panel for Ansul systems.
At CASCO. we have extensive experience in the installation and design of CO2 fire suppression systems; in fact we have installed and maintained CO2 systems since our inception in 1986.
We have worked with major corporations to design CO2 systems nationwide for a variety of applications. Call today and speak with one of our knowledgeable professionals.
The Montreal Protocol and the U.S. Clean Air Act together have effectively caused the elimination of Halon 1301 from new use throughout the U.S. as well as the rest of the world. While Halon has been known as an extremely safe and effective fire suppressant for about thirty years, it is a member of the chemical family known ozone depleting agents.
As a result, The Clean Air Act dictated that production of Halon 1301 would cease by December 31, 1993. Utilization of new agents as well as recycling of existing Halon would provide the source of fire suppressants beyond this phase out date. It is important to understand that the Act did not make ownership or use of Halon 1301 illegal. Rather, the Act strongly encourages proper use and management of Halon stocks that currently exist. It only precludes any further production of Halon. As a result, many Halon 1301 systems remain in use today and recycled Halon is available for recharging these systems.
FIRE ALARM SYSTEM
Fire detection and alarm systems are designed to provide warning of a fire outbreak and allow for appropriate fire fighting action to be taken before the situation gets out of control, resulting in serious damage to property and possible loss of lives. This is why it is vital to have a properly maintained and fully functional system because you have a lot of capital invested in your fire system that is wasted money if it did not work. The Fire Precautions (workplace) regulations require a system of maintenance and failure to keep a Fire detection and Alarm system in good working order is a Criminal Offence. Fire Detection and Alarm Systems, Designed, Supplied, Installed and Maintained by us. We deal with the world famous and quality & reliability proven manufacturers in U.S.A & U.K. Such as Edwards System Technology (EST – U.S.A), Mirtone International, Canada, Deetech – U.K, C – Tec Co., - U.K, Zeta – U.K and Secutron Inc, Canada
A building may have some systems need to be connected with fire alarm system. They are AHU's Lift / elevator, pressure fan and supply Fan, fire check doors or smoke escape fans exhaust fans. All these may be connected individually or as a group to BMS. BMS (Building) Management System) shall be interfaced with our Fire Alarm System.
Non Addressable systems (previously known as Conventional) are more suited to smaller buildings. The fire control panel will indicate a fire by illuminating an led to the relevant zone. A zone will have a grouping of detectors which would have to be individually checked to identify which detector is in alarm state. This is a cost effective solution for a smaller building.
Analogue Addressable systems are more advanced and offer the exact location of a fire by a detector having its own number. The panel offers text description of location and type of detector in fire or fault. Unwanted alarms are greatly reduced as the panel will indicate if a detector is contaminated and will compensate instead of going into alarm like a non---addressable system would. Each detector is constantly tested by the control panel. Sensitivity levels of detectors can be adjusted for day and night. Fully programmable and we can offer remote dealing so an Engineer can look at your system from our base.
Wire Free is an Analogue Addressable system which offers all the benefits of a hard wired system but also has the addition of:
- Each detector can be installed in less than 10 minutes
- The fabric of the building is protected and undamaged
- No cables
- The system can easily be moved or upgraded as building use changes
- All systems can be connected to an Alarm Receiving Centre to connect you straight to the Fire Brigade
The only way you can be confident that your system will work in the event of a fire is if a professional company using properly trained and qualified engineers regularly services it. Our Engineers are BFPSA trained and have an excellent knowledge of the updated code of practice which is BS5839-part 1 2002(previously 1988). The new code of practice states any person who designs, installs and maintains Fire Detection and Alarm systems must be able to prove their competence. BFPSA training courses are a recognized form of proof.
