History of the fire hose

Until the middle of the 19th century, most fires were fought with water carried in buckets. The original hand pumps discharged water through a small tube or monitor attached to the top of the pump tub. It wasn’t until the late 1860s that fire hoses became widely available to more easily transfer water from hand pumps and later steam pumps to fires.

In Amsterdam, fire chief Jan van der Heyden and his son Nicholas took firefighting to its next level by building the first fire hose in 1673. These hoses were made of 50-foot (15-meter) leathers sewn together like a boot leg. Even with the pressure limitations, connecting the hose to the gooseneck nozzle allowed for closer and more precise use of the water. Van der Heyden also became famous for an early version of a suction hose that used wire to hold it tight. In the United States, the fire hose was introduced in Philadelphia in 1794. This canvas hose did not last long enough and then a stitched leather hose was used. Sewn leather hose tended to burst, so a hose made of leather held together with copper rivets and washers was invented by members of the Humane Hose Company of Philadelphia.

Around 1890, unlined fire hose made of circularly woven linen threads replaced the leather hose. They were much lighter, and when the fibers of the hose, which were made of linen, got wet, they swelled up, stiffening the fabric and making it difficult to transfer water. Due to their lack of durability, unlined hoses were quickly replaced by rubber hoses in urban fire service use. And until the 1960s to 1980s, they were used in indoor hose lines and hose racks. In January 1981, the Occupational Safety and Health Administration revised its standards to no longer install unlined hoses for indoor hose lines.

After the invention of the vulcanization process as a means of curing soft, raw rubber into a harder, more useful product, the fire department slowly evolved from bulky and unreliable leather hose to uncoated linen hose and then to a laminated rubber. This rubber hose was as bulky, heavy, and stiff as the leather hose, but not as prone to leaks. It was also more durable than unlined linen hose. Its complex construction resembles some of the hoses used in industry today, for example, the fuel delivery hoses used to service aircraft.

Fire hoses that are used today.

The fire hose is a hose with the ability to withstand very high pressure, which is used to transfer water or fire retardant materials to the fire. A fire hose can be connected to a fire engine or a fire hydrant. which must withstand pressure between 800 and 2000 kPa. And after use, they must be dried because the water or materials that remain in the hose after extinguishing the fire may cause damage and wear of the hose, and as a result, it will not work properly in times of need. When choosing a fire hose, you should consider things like the material of the hose, the length of the hose and the maximum pressure that the hose can withstand. Because if the wrong hose is chosen, the hose may burst and stop the extinguishing operation and cause personal and financial damage.

Types of fire hoses by gender:

  • Rubber fire hose
  • Tape or fabric fire hose
  • Hose fire hose
  • Canvas fire hose

Fire hose

Rubber fire hose

As the name suggests, this type of hose is made of rubber and is used for cases where the fire is in its early stages and its use does not require training, and it is usually located in fire hoses as shown below. The appearance of this hose in the state without water and in the condition of water is similar to each other.

Fire hose

Tape or fabric fire hose

This hose is in the form of a flat strip without water. To use this type of hose, you must first spread it completely on the ground and then open the faucet to fill it with water. To use this hose, people must be trained and it should be noted that this hose can be assembled in different ways.

Hose fire hose

It is used to catch water on open sources.

 

Fire hose

Canvas fire hose

The tarpaulin hose consists of an outer layer and an inner layer, the outer layer is made of perlon yarn with polyester and circular texture, and the inner layer is made of rubber and has features such as high flexibility, high durability against external factors such as Heat and chemicals are compatible with all types of weather and long-lasting and anti-wear.

 

Fire hose

When choosing a fire hose, attention should be paid to things such as the length of the fire hose, the type of hose, and the pressure that the fire hose can withstand. A fire hose reel consists of a collecting hose capable of providing a continuous supply of controlled water.

Fire hoses that have more capacity carry more water at lower temperatures. If the hose has a smaller diameter, it needs more pressure. The most important factor in determining the efficiency of the fire hose is the diameter of the hose.

The fire hose reel is the first offensive piece of firefighting equipment. This method is designed to be used as a quick response method by anyone to deal with fires in the early stages. Hose rings are suitable for Class A fires: paper, textiles, wood, most plastics and rubber.
Be careful not to use a fire hose on electrical fires, remember that water conducts electricity, so using a fire hose ring in these situations can lead to electrocution!

Fire hoses rings are easy to use and provide almost unlimited water supply as they are connected to the mains supply and should be around 35m long. Before working with the fire hoses, it must be fully extended. A fire hose loop is designed to provide at least 20 liters of water per minute, in a controlled manner, up to a maximum length of 36 meters of fixed loop.

Fire hoses rings are made up of lengths of non-shrink tubing. They are permanently connected to a power source and consist of a main on/off valve, a hose guide and a hose with a nozzle. A nozzle attached to the end of the hose enables the operator to control the direction and flow of water towards the fire. Fire hoses for residential buildings as well as fire engines can be supplied separately.

Fixed wall fire hose ring

These types of hose rings are permanently installed on a wall or in a fire box and are connected to the building’s main water supply. They are installed in places that are easily accessible and used to extinguish or contain small fires. There should be enough wall space around these rings to ensure that there are no obstructions when they are in use. If you use the fire department, the equipment in the fire box includes a fire hoses, a fire reel, and if you use a canvas hose on the reel in your fire box, you must also have a fire coupling inside the box. Use your fire extinguisher. Of course, it should be said that in some fire boxes, a space is provided for placing fire extinguishers.

Arm fire hoses ring

Unlike a fixed wall hose, the arm hose ring is mounted on a large hinge. The advantage of the arm ring is that it can be turned outwards using a hinge when in use. This gives users more flexibility, especially if you need to make sudden or jerky movements to put out or contain a fire.

Fire hose rings should not be used for cleaning purposes, as this can result in you being fined.

All hose rings are required to be inspected and tested every 6 months according to the standards. This test is to ensure the performance of the hose reel in emergency situations.

User guide when using fire hoses reel

When using a fire hoses reel, you must first announce your intentions to anyone who may be in your vicinity. Once turned on, you should follow these steps with extreme caution:

  1. Make sure there is a suitable route for your emergency exit.
  2. (for standard rings) Open the tamper-proof seal, if present, to make the ring usable.
  3. Run the water in the faucet.
  4. Pull the hose as far as necessary to reach the fire.
  5. Carefully navigate your way to your destination while maintaining a clear line of sight to your predetermined exit.
  6. Allow the water to flow out of the nozzle by turning it on.
  7. The goal is to direct the stream of water toward the fire you want to extinguish. Do not overdo it; When the fire is extinguished, close the nozzle. Using too much water can lead to unnecessary damage and additional costs to you or your business.
  8. If the flame is not extinguished with a fire hoses, you should drop everything and go to the predetermined exit as soon as possible. Don’t try to be a hero.
