Journal of testing and recharging fire extinguishers

Fires in the city of Moscow, as well as any other locality in the country, are not uncommon. The focus of fire damage can be quite harmless.

For example, a power supply that ignited from overheating or a TV that flared up due to a voltage drop.

It is to suppress a fire in a small area that the powder fire extinguisher OP-5 was developed.

This device is compact and light enough to be used by one person.

The main purpose of the fire extinguisher OP-5

Powder fire extinguisher OP-5 is quite versatile. To be sure that the device will show high efficiency, you should pay attention to the technical characteristics of the fire extinguishing agent indicated in the marking.

The designation ABCE means that the model is capable of fighting fires of the following classes:

1. A, ignition of solids and mixed materials;
2. B, burning liquids;
3. C, ignition of gases;
4. E, fire of electrical installations under voltage.

A fire extinguisher should be used only in cases where the duration of the ejection of the jet and the equipment of the model with a charge are capable of extinguishing the fire. Also, the fire extinguishing ability of the device will be zero if it is used to process substances that do not require oxygen for combustion. These include, for example, alkali metals and some acids.

To get at your disposal a device with a quick start-up and a simple technique of use, it is worth purchasing an OP 5 Z fire extinguisher. This is a pumping type, there is gas under high pressure inside the housing cylinder.

The release of the active substance occurs almost instantly. The nature of the action of powders on the area of ​​fire damage differs from other types of working fluid used in fire extinguishers.

The principle of operation of the powder fire extinguisher OP-5

The device of the OP-5 fire extinguisher, which is a design of a vessel under pressure, implies an almost instantaneous release of a powder jet. Getting on the source of ignition, the fire extinguishing agent creates a layer that blocks the flow of oxygen.

Features of powder fire extinguishing are as follows:

• all types of powders do not create a risk of short circuit, which is the difference between foam and aqueous solutions. OP-5 can be used to extinguish electrical installations whose operating voltage is less than 1000 V;
• when processing with an active agent, the treatment zone does not cool, as does a carbon dioxide fire extinguisher;
• a full assessment of the level of danger shows that OP-5 in a room of limited volume is more attractive, since the active substance cannot cause damage to the respiratory system, as does the carbon dioxide of devices of the corresponding brand.

However, the powder fire extinguisher OP-5 Z AVSE, as well as devices with other types of fire extinguishing powder, have disadvantages. One of them is a sharp drop in visibility when operating indoors. The active substance is finely dispersed, when ejected, the suspension hangs in the air.

The description of the shortcomings of the device will not be complete without mentioning the secondary damage. It is expressed in damage to trim elements, device cases that are in plain sight. The powder is able to fuse into a variety of surfaces at high temperatures in the fire. It may not be possible to remove it.

To start extinguishing a fire, a fire extinguisher must be moved to the source of ignition. To start, the seal is removed, the pin or other blocking element of the locking device is removed.

When this is done, to start the ejection of the powder jet, the block with the handle is taken all the way up and the latter is pressed. The flow of the active substance occurs all the time while the operator holds the trigger in the depressed position.

After using the downloaded OP-5, it must be recharged. Also, in order to preserve the suitability and confidence in the effectiveness of the application, you should carefully observe the storage conditions of the device, the inspection periods.

The powder fire extinguisher should be recharged at least once every 5 years, from the moment of the last calibration, regardless of the actual service life.

Device Specifications

The mass of the fire extinguisher OP-5 is a maximum of 6.8 kg in a fully equipped state.

The device must be installed in special wall brackets, its dimensions allow installation on stands or lockable cabinets.

The service life of the fire extinguisher OP 5 declared by the manufacturer is 10 years. Devices put into service - must be recharged once every 5 years. Storage of powder pump fire extinguishers is also subject to certain rules.

Products are stored and operated at temperatures from -20 to 50 degrees Celsius. When installing devices, moving, storing - it is worth considering the features of the engineering solution.

In particular, when fire extinguishers are charged, they are high-pressure gas cylinders. Deformation of the body, sharp mechanical, force impacts, falls from a height are not allowed.

Conclusion

Light weight, compactness, ease of starting operations, quick delivery of the extinguishing agent, its high versatility make the OP-5 powder fire extinguisher an extremely popular product. They are equipped with fire shields of small workshops, workshops of enterprises.

The device shows high efficiency when used in transport. Can be successfully used in offices, apartments, hotels.

Today you can buy OP 5 with different characteristics of the powder. Possibility of choice - allows you to optimize costs by carefully analyzing and predicting possible types of fires and their level of danger.
