Answer :

Purpose of fire fighting system :

The main purpose of fire fighting system is to increase the safety of emergency for people and building occupants by providing information about how firefighters typically interact with building features and fire protection systems during fires and similar emergencies. By better understanding the needs of the fire service, designers and code officials can work together to streamline fire service emergency operations within the built environment. Originally published in 2006, this manual cited specific criteria for many of the building features discussed and code references.

  The combined efforts of designers, code officials, and related stakeholders can result in safer workplaces for fire fighters. When designs are tailored to better meet emergency service operational needs, the time and complexity needed to mitigate an incident is often reduced. Designers in this manual can include architects, engineers, planners, and design technicians. Code officials can include fire marshals, fire inspectors, fire prevention officers, building inspectors, and plan reviewers. Other stakeholders include building owners and developers, security professionals, and construction professionals. Many portions of the prescriptive codes and standards governing buildings and fire protection systems allow for design variations. The resulting flexibility permits the selection of a variety of design options.

Design of fire fighting system :

  The design of any fire-protection system is an exact science that takes into account a building’s use, occupancy, footprint, and even its other installed systems.Fire-protection systems are complicated and sophisticated, and are different for just about every building, notes Jeffrey E. Harper, engineering manager and vice president at Rolf Jensen & Associates Inc. An organization of fire-protection and security consultants based in Chicago. Every well designed system, whether it is being designed for a new building or being installed as part of a renovation or retrofit, must be developed with specific objectives in mind. Planning for fire protection involves an integrated approach in which system designers need to analyze building components as a total package. In most cases, the analysis needs to go beyond basic code compliance and the owner’s minimum legal responsibilities for providing protection. The following points are the design of fire fighting system :

• Code compliance : Code compliance is the first objective in any design. Codes are legal minimum requirements. Compliance with building codes is like bandwidth. It gives a broad-brush range that has to be applied to every single building in the jurisdiction. Sometimes it hits the mark and provides cost effectiveness and protection, other times it might not hit the mark.
• The basics : In the design process following are the typical goals of fire protection system :

1. Saving lives

2. Saving property

3. Preserving business continuity

It all depends on how a building is used and occupied. A warehouse or storage facility, for example, will have different fire-protection requirements than a multi-tenant office building.  

• Detection system : The main benefit of good detection (beyond triggering the alarm system) is that, in many cases, there is a chance to extinguish a small, early blaze with a fire extinguisher. Modern smoke-detection systems go beyond the small device that senses smoke and triggers the alarm system. Intelligent smoke detectors can differentiate between different alarm thresholds.
• Alarms and notification system : Alarm systems are a must in any facility - alarms that alert building occupants of a fire and alarms that alert emergency public can through a central station link so they can initiate a response.
• Suppression system : Sprinklers are the most widely specified suppression system in commercial facilities - particularly in occupied spaces. The following are the types of fire suppression system :

1. Gas system

2. Kitchen fire suppression

3. Water mist system

4. Foam deluge system

5. Pneumatic heat detection tube

• Maintaining safety : An improperly maintained system lacks reliability and, therefore, true protection. If a system is not maintained properly, its reliability degrades rapidly. Fire Fighting, techniques and equipment are used to extinguish fires and limit the damage caused by them. Fire fighting systems depends on removing one or more of the three elements essential to combustion: fuel, heat, and oxygen.
