Fire Fighting Hydrant Systems are the most commonly used systems, in many residential and industrial projects. In most news clippings about a fire, you can see a fireman shooting water up to 8stories high or more, that fire man is using the Fire Hydrant System. Such is the power of the Fire Hydrant System that water can be shot right up to 8 floor, directly into the fire.
It will be a superficial system. With respect to large areas, in general. Fire Hydrant System installation is relatively easy. This is very effective extinguishing system suitable for various plants and high-rise buildings as well as commercial complexes.
Fire Hydrant Systems
The system mainly consists of water storage reservoir underground or abovegroundpump set, piping ring around the building and terminals in side the building, hydrant valves, hoses, branch pipes with nozzles and hose boxes.
On the ring main the hydrant stand posts are provided with hydrant valves. The system is of two types one is wet riser and other dry riser. The wet riser system is automatic type and dry riser is of manually operable.
In case of fire, the hose can be connected to the hydrant valve with the nozzles at the outlet end and the pump can be started.
For automatic operation of the pump the jockey pump is provided which normally pressurise the pipes and as soon as the valve is open and pressure reduces the main pump starts automatically.
With the help of pressure and ample water, the jet from the nozzles can be projected at the base of fire to extinguish completely. How do Fire Hydrant Systems Function? This water well is connected to the pump room. From the pump room, there are two to three main pipes.
These pipes form a network of pipe that cover the factory compound and the factory. The pump has the work, to continuously filling all the pipes connected with water under pressure. The pressure is nearly 7bar to 10bar. When a fire is seen by a person, he activates the hydrant system and points it in the direction of the fire.
A very strong flow of water now, attacks the fire and the fire is eventually extinguished. The pump continuously pumps the water to maintain the system pressure. What are the advantages of Fire Hydrant Systems? Fire Hydrant Systems are very strong and can be used from medium to large sized fires.
Fire Hydrant Systems, have a long range. Since the Fire Hydrant System is spread out, the fire hydrant can attack fire from different angles. This entire systems requires low maintenance and virtually, does not leak water. Besides this, Fire Hydrant Systems have a long life.
What are the disadvantages of Fire Hydrant Systems? There are few disadvantages. The first is that it has to be manually activated. The flow of Fire Hydrant System is so strong that, there are two men required to hold the water hose. Fire Hydrant System, may cause damage to the instruments or machines.
Fire Hydrant systems are very popular and hence many, Clients search only for Fire Hydrant Companies or Fire Hydrant System Suppliers; but the important thing to understand is that it may not be the most efficient system.

About Us.Fire Hydrants, or hydrant outlets, are installed within the building to enable firefighters to connect their hoses to a water supply to fight fires.
Alternatively, they may be kept full of water and supplied from tanks and pumps in the building. Normally, the wet fire hydrants are also coupled with fire service inlets. Building height generally determines which type is used.
It is also important in the planning stage to ensure that an external source of water supply, such as street hydrants, is within reasonable distance from the building.
The fire service should not have to travel far for an external water source. This is the use of first aid fire fighting equipment such as hose reels accompanying the manual alarm call point, the portable fire extinguishers etc.
They are meant to be the first line of defence by the occupants themselves who spot the fire before the arrival of fire brigades and are designed to enable a person with little or no training to tackle a fire in its very early stages.
Automatic suppression systems can either be equipped with their own heat sensing element such as an automatic sprinkler system which operates when the sprinkler head is heated to its nominal operating temperature or are operated by the initiation of a detection system such as a gaseous system which operates by the initiation of heat or smoke detectors.
Automatic sprinkler systems are considered to be the most effective and economical way to apply water from fixed systems. It is designed to act upon a fire at a pre-determined temperature by means of a water spray. It could extinguish the fire or control its spread.
The extinguishing mechanism of sprinkler water spray includes combustible materials to prevent further fire spread and displacement of combustible vapour and oxygen steam. When considering the increase of the compartment size, or the reduction in passive fire protection systems by using sprinkler systems, the sprinkler system should meet the relevant recommendations of commonly used standards such as BS Part 2, i.
The design of a sprinkler system is determined by the hazard classification of the building occupancy. Each category has its own minimum design density of discharge and assumed maximum area over which this design density is to be achieved.
There are four main types of sprinkler systems — wet, dry, alternate and pre-action system. They are normally chosen by the nature of the area to be protected, whether storage of water in the pipework would pose a risk due to process or weather condition, or where the risk of accidental discharge is to be eliminated. All rights reserved.Aside from the general purpose of delivering water for fire fighting, the hydrant design selected must be based on a number of operational elements.
How many and what size hose connections are required. The established hose sizes and coupling threads in the region. Current and future configuration of fire apparatus. Issues of clearance and visibility. Operating characteristics of the hydrants. Amount of head static pressure that is present in the system. Climatic conditions in the area. In commercial and multi-story apartment zones, this volume should increase based on the required fire flows of the buildings being protected.
If the required fire flows are several thousand GPM, the required flow will usually have to be met by two or more hydrants flowing simultaneously. The operations of the fire department or fire brigade must be taken into consideration. In instances where new hydrant systems are replacing poor or nonexistent systems, new fire fighting approaches need to be developed to make proper use of the new system. Hydrant designs should capably and easily provide necessary water to fire engines currently in service as well as more modern fire engines which may be purchased in the future.
Accordingly it may be appropriate to specify fire hydrants which have medium diameter hose outlets as well as a large diameter pumper outlet. In the event of a major emergency, fire companies may be requested from multiple jurisdictions.
Hydrant outlet threads should meet the regional standard for compatibility among all fire engines, regardless of origin. If no large diameter outlet size and thread has been established, we recommend the 5" Storz configuration. Hydrants need to be readily recognizable and accessible. Placement and installation considerations should take into account the shape of the hydrant as well as the positions of valves and outlets. Specific suggestions regarding hydrant placement are presented later in this feature.
Hydrants must be simple and reliable to connect to and to operate. Operating nuts should be pentagonal or triangular in design to reduce tampering by unauthorized persons. Discharge valves should be specified to open by turning counter-clockwise and close clockwise. Underground valves on water mains and on the hydrant branch line should operate according to local or regional standards. Hydrant designs must be appropriate for the amount of head static pressure that is applied to them.The United States has the highest fire losses in terms of both frequency and total losses of any modern technological society.
New facilities and renovation projects need to be designed to incorporate efficient, cost-effective passive and automatic fire protection systems. Fire protection engineers must be involved in all aspects of the design in order to ensure a reasonable degree of protection of human life from fire and the products of combustion as well as to reduce the potential loss from fire i.
The analysis requires more than code compliance or meeting the minimum legal responsibilities for protecting a building; that is, building and fire codes are intended to protect against loss of life and limit fire impact on the community and do not necessarily protect the mission or assets, or solve problems brought upon by new projects with unique circumstances.
Identify critical systems: diesel generators, etc.
Basics of Fire Fighting Hydrant Systems
The success of any complex project hinges on getting all the stakeholders, owners, designers, special consultants, and AHJs working together in a collaborative manner to achieve performance-based design solutions. Design Team —It is most important that the project delivery team include a Fire Protection Engineer with adequate experience and knowledge in fire protection and life safety design.
The Fire Protection Engineer should be involved in all phases of design, from planning to occupancy. GSA and DoD require a licensed professional engineer on their projects. Design Standards and Criteria i. Building Construction Requirementsat a minimum will address the following elements:. Fire Detection and Notification System Requirementsat a minimum will address the following elements:. Fire Suppression Requirementsat a minimum will address the following elements:.
Emergency Power, Lighting, and Exit Signageat a minimum will address the following elements:. Special Fire Protection Requirementsat a minimum will address the following elements:. The concern for terrorist attacks has caused design and engineering professionals to address integrated fire protection and security measures for the building site as well as within the building.
For example, perimeter protection measures must be well-designed to ensure that fire departments can still access sites and buildings. With the proliferation of vegetative roofs on buildings to reduce heat island effect and control storm water runoff, consideration must be given to firefighters having to ventilate a structure during a major fire event. Provide adequate roof hatches and other access points for firefighters.
Virtually every project that requires fire protection must also meet sustainability goals. Further, consider life-cycle cost when making decisions on materials, equipment and systems. Bollard spacing for accessibility related to access for fire vehicles and personnel.
The Americans with Disabilities ADA Act calls for bollards to have 36 inch clear space between them to meet clear opening requirements.The Fire hydrant allows the fire department to gain access to the fire system quickly and efficiently.
Ensure that the system has straightforward modification and upgrade and long term compatibility with new developments. The underlying considerations that run throughout the design of these systems include. The products that would be used for the Fire Hydrant system are highly effective products that would provide top quality fire fighting system for the school facilities etc. The design allows for ease of operation and maintenance.
During operation a hose is attached to the hydrant, and then the valve is opened to provide a powerful source of water, depending on various factors including the size and location of the attached water main. This hose can be further attached to a fire engine, which can then use a powerful pump to boost the water pressure and possibly split it into multiple streams.
If the temperature is too high, he can crawl on the floor and spray the water of the hose reel on to himself, gaining a high chance of not being injured. The Indicator post is used to control the underground fire service mains. It comes with a window sign to indicate whether the valve is open or closed. Field adjustment may be made by simply cutting the top of the stem to suit the post length. Vidya Nagar west, llnd street N. S Engg College P. O PalaghatKerala, India.
