What Do You Need To Know About Fire Sprinklers?

A fire sprinkler system is one of the most effective firefighting devices that is widely used both in residential and business zones. Although it’s often thought that fire sprinklers are triggered by small amount of smoke, that’s not the case in reality. These systems are actually activated by intense heat and one sprinkler head gets activated at a time. These are advanced firefighting devices that are designed in a way so that these can deal with fire using the minimum possible water. This helps save the users from any kind of costly water damage as well as fire damage.

What are the different types of fire sprinkler systems?

A fire sprinkler system is considered as an effective fire fighting system and there are two different types of sprinklers. Wet sprinkler systems are mostly used in commercial buildings. These are composed of sturdy pipes that are made of steel. The water in these pipes are kept under pressure and it gets instantly released when the sprinkler head gets triggered. These systems are quite reliable and simple to use and these have low maintenance system.

Another type of fire sprinkler system is dry sprinkler system. These types of sprinklers are filled with compressed air, instead of water. Once the head of the sprinkler opens, a valve gets opened and the compressed air gets released through the sprinkler head. Once the entire air is released, the pressure within the pipe gets changed and this allows the pipes to get filled with water. As it takes around a minute for the pipes to get filled with water, the dry sprinklers release a considerable amount of water that is highly pressurized. Although there are less chances of floods due to a leak in these systems, dry sprinklers are quite complicated and costly to maintain. These systems are usually used in unheated warehouses.

How does a fire sprinkler system work?

It’s of great importance to know the functioning process of a fire sprinkler system in order to make it run smoothly.

• When a fire occurs, the air around it gets heated and redirected towards the ceiling. The heat gets spread across the ceiling and meets the sprinkler heads. This triggers the sprinkler to turn on. 
• In order to get turned on, the head of a fire sprinkler must be able to detect a specific temperature. Usually, this temperature is around fifty seven to seventy four Celsius. 
• Sprinkler heads are equipped with glass cylinders that are filled with a glycerine liquid. When heated to the correct temperature, the glycerine liquid gets expanded. 
• After that the glass breaks when the sprinkler head is activated. 
• The head of the fire sprinkler is attached to a huge network of pipes that are placed either in the ceiling or behind the walls. After the sprinkler head is activated, the valve that remains connected to the pipes, opens up and releases the water in a downward direction. 
• Finally, the water spray extinguishes the fire and prevents it from getting spread in other parts of the building. 

This is how a fire sprinkler system works.

History of Fire Sprinklers Demostrated via Video

A fire sprinkler framework is a dynamic fire assurance strategy, comprising of a water supply framework, giving satisfactory weight and flowrate to a water dispersion channeling framework, onto which fire sprinkler systems are associated. Although generally just utilized as a part of processing plants and substantial business structures, frameworks for homes and little structures are presently accessible at a financially savvy price. Fire sprinkler frameworks are widely utilized around the world, with more than 40 million sprinkler heads fitted every year. In structures totally secured by fire sprinkler systems, more than 99% of fires were controlled by fire sprinklers alone.

Steps to Maintain A Fire Hydrant System

A fire hydrant system is considered to be an efficient device when it comes to handle a fire, and hence, it’s important to keep a fire hydrant system in a sound condition, so that it can perform all the functions properly as and when needed. No matter whether you are responsible for keeping a business premise secure or you are in charge of the safety of an entire society, you must be careful enough about the maintenance of the fire hydrant systems.

Not keeping the fire hydrants of your community in a sound condition may turn out to be fatal at times. Here are some important information that will help you maintain a fire hydrant system properly –

• Paint it properly – Hydrants that have been installed before2009, should be painted in such colours that will make these visible under adverse weather conditions and light. In case the hydrants have been installed after 2009, you need to follow the process of coating. Since 2010, the manufacturers of fire hydrants system started to coat these with a double polyurethane enamel paint. This is applied on the hydrants following a hydrostatic process as it ensures a durable and long lasting finish. This paint is quite hard and is resistant to light. In fact, these paints can’t be recoated. In order to recoat these, one needs to clean and sand the surface and remove the glossy appearance. 
• Check the functionality – In order to keep the fire hydrants in a functional condition, it’s important to check the flow of the system. Make sure you open and close the auxiliary gate valves of the hydrant at regular intervals. This will help provide a reliable source of water as and when needed. By checking the flow of water, you will also get an indication of the total amount of flow and pressure available in each of the hydrants. This information is extremely beneficial for the local fire authority and the water service planners. 

These are the two most important tasks that you should perform in order to keep a fire hydrant in a sound condition. There are certain things that you should keep in mind while performing the flow test of a fire hydrant. Here are the things that you must do –

• First off, choose a safe and vast area where the water can flow directly. This is important as the water that flows out of a hydrant can damage the vegetation, landscapes, structures and the private properties of the area. 
• Establish a fixed schedule for testing the fire hydrants every year. 
• Open and close the valves of the hydrant to prevent water hammer. This can also cause breaks in the water mains.  

Since it’s quite costly to replace fire hydrants, it’s crucial to follow a proper maintenance system and follow the exact schedule of check-ups. This ensure proper functioning of these equipment, when needed most.
