Application

In the event of a fire, it is necessary to act actively, and a backpack fire extinguisher will quickly cope with the task of removing the flame. Comfort is provided by the presence of shoulder straps or straps, which are behind the firefighter. The device can be taken with you on a hike.

The fire-extinguishing medium in the device is water or a non-corrosive substance. The ignition is localized by quenching or by applying strips. This is done both with the use of water, and chemically non-aggressive solutions.

Design

The backpack fire extinguisher does not have a complex design. The liquid container is in the shoulder bag. In order to easily transfer the device, there are belts on the case. For each person, these elements can be regulated.

The device has a lot of weight, so the straps have softening cushions. To prevent negative consequences from prolonged contact with the container on the wound, there is thermal insulation. The liquid is drained by a hand hydropump - pump. Although the weight of the device is large, it is still convenient for them to use, since the nanoscale is made of polypropylene.

Operation of the device

Knapsack forest fire extinguisher has a hydropump that allows you to set 1 of the operating modes:

• Compact water jet;
• A sprayed stream;
• Foamy jet.

For the last mode, a special nozzle is included. In addition to the functional equipment, there is a capacity for drinking water, since the device is used outdoors. Manufacturers of backpack fire extinguishers create goods with different materials. Some properties may also differ.

How to choose?

That the fire extinguisher knapsack worked effectively, you need to choose a device with the appropriate characteristics. Due to good performance it will be possible to quickly extinguish the fire. The speed of the device depends on the number of liters. The device in 3 l / min perfectly copes with its functions in emergency situations.

Pay attention to the volume of the working capacity. The more this indicator, the better the fire will be extinguished. But since the device is used when it is behind your back, you do not need to choose a heavy device. It is enough to buy a knapsack forest fire extinguisher in 25 liters.

It is necessary to take into account the length of the water column. With a vertical directivity it is better to choose a device with an indicator of six meters, and with a horizontal direction - 12 meters. Devices are estimated by the size of the working capacity. It is necessary to choose instruments with parameters 370х190х430 mm (width, depth, height). The kit should have a shoulder bag and a hydraulic pump.

Comparison

Allow early fire extinguishers to allow knapsack fire extinguishers. The photo of the device shows that it is very user-friendly. But each device may have restrictions on the use. They are excellent in those cases where it is necessary to eliminate grass-roots fires, and there is no access to technology.

Devices are used not only in fire services, but also in private, country houses. Foam extinguishers are forbidden to use in cases where a fire is caused by a short circuit. Powder devices are used almost everywhere, but the exception is the quenching of alkali metals and other substances that burn in an oxygen-free environment.

Tips for using

This device effectively performs firefighting. Pros of a fire extinguisher set:

• Directed jet;
• free hands;
• You can include different modes.

With the help of a hand pump, water is supplied with the movement of the bolt back and forth. To quickly extinguish a fire, you need to use a compact and sprayed jet in situations where it is needed. For example, the length of the liquid flow in the first case is 8-9 m, and the sprayed jet is 3.5 m. Therefore, when the ignition is localized, it is possible to approach the source. With the correct assessment of the situation and the use of a suitable volume regime is sufficient to eliminate the source of ignition.

So, this device though and compact, but has a number of advantages in comparison with other fire extinguishers. If there is a fire in the suburban area, you should not carry buckets, since you can use a backpack extinguisher.

It is necessary to regularly check the operability of the device. In the event of a fault finding, the defect should be rectified, otherwise the device will not be able to perform its functions. The fire extinguisher must be in a place designated for it.

Not always water can be close to a fire, and the shoulder device is comfortable to work with and at any time can be used. It is necessary only to monitor the storage conditions of the device, not to expose it to high temperatures and other negative factors for it.
