How to use a powder fire extinguisher OP-5

Make sure the fire extinguisher is charged (look at the pressure gauge).

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 those indicated in the marking specifications extinguishing agent.

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.

The principle of operation of the fire extinguisher is based on the use of the energy of the gases released during the operation of the gas generator for aeration and the release of the fire extinguishing agent from the fire extinguisher body to the combustion source.

When the lever of the starting device is pressed, the gas generator is activated and the release of working gas begins. It is necessary to wait at least five seconds for the necessary pressure to build up in the fire extinguisher housing and, only after that, start extinguishing the fire.

Instructions for using powder fire extinguishers:

The principle of operation of the fire extinguisher is based on the use of the energy of the compressed gas generated by the gas generator for aeration and the release of the fire extinguishing agent.

To activate the fire extinguisher, pull out the sealed pin and press the handle of the fire extinguisher starter. In this case, the striker activates the gas generator, as a result of which the working time enters the fire extinguisher body, aerates the powder and creates a working pressure in the fire extinguisher body for no more than 6 seconds, after which the fire extinguisher is ready for operation. Further control of the operation of the fire extinguisher is carried out by pressing the hand on the handle of the spray gun, while the fire extinguishing powder is fed through the sleeve and nozzle of the spray gun to the fire.

The principle of operation of powder fire extinguishers:

The principle of operation of a fire extinguisher is based on the use of compressed gas energy to release a fire extinguishing agent.

On the scale of the pressure indicator, the working pressure in the fire extinguisher body is monitored. The pointer of the pressure indicator should be in the green sector of the scale, which means that the value of the working pressure corresponds to its set value. The location of the arrow indicator in the red sector of the scale indicates insufficient pressure in the fire extinguisher body.

[Principle of operation: the OP-5 fire extinguisher is activated by pressing the trigger lever. After that, the needle rod pierces the membrane of the gas cylinder. The working gas (carbon dioxide, air, nitrogen, etc.), leaving the cylinder, enters through the siphon tube from the air bottom. In the center of the siphon tube there are a number of holes through which part of the working gas exits and the powder is loosened. The loosened powder under the action of working gas pressure is squeezed out through the nozzles on the ignition source. In the working position, the fire extinguisher must be held strictly vertically.]

10. What conditions must be observed when extinguishing a fire that is located near a high-voltage contact wire (equipment) with OU-5, OP-5, 0KhP-10 fire extinguishers?

1. What is the frequency of testing knowledge on electrical safety for electrical personnel?

Periodic testing of personnel knowledge is carried out:

Once a year - for electrical personnel directly servicing existing electrical installations or carrying out repair work in them.

1 time in 3 years - for engineering and technical personnel of electrical personnel, as well as for safety engineers admitted to inspect electrical installations.

If the expiration date of the certificate falls on vacation or illness, it is allowed to extend the validity of the certificate for 1 month from the date of entry to work. The decision to extend the validity of the certificate is not issued.

Persons who violated the PTE of electrical installations of consumers or PTB are subject to an extraordinary knowledge test.

2. What do you know about shorting "+" and "-" wires to the body of the car?

The presence of leakage on the body of the car is checked by turning off the insulation control toggle switches one by one. In this case, both control lamps should go out. Even a slight glow of one of the lamps when the toggle switch is turned off indicates that the insulation is broken, and the current enters the car body. In working condition, both lamps burn at full heat, because. the same current flows through them. If the insulation of the negative wire is broken, the “+” lamp will burn less brightly than the “-” lamp, and when the toggle switches are turned off, the “+” will go out, and the “-” will burn. In the event of a violation of the insulation of the “+” wire, the “-” will go out, and the “+” will light up. Thus, the bright light of the “+” lamp indicates the presence of a short circuit to the body of the positive wires, and the “-” lamp indicates the presence of a short circuit of the negative wires.

3. How to connect a high-voltage undercar line to an electric locomotive?

The connection of the high-voltage line of the train to the electric locomotive is carried out by the FEM or LNP in a strictly defined sequence after the locomotive is hitched to the train. Beforehand, the driver of the electric locomotive must lower both current collectors, remove the keys of the controller (the control panel of the electric locomotive) and be present at the electrical connection of the electric locomotive with the train. In this case, the keys to the controller should be kept only by the driver of the electric locomotive.

The electrician or the head of the train from the idle receiver on the head car, and the driver from the idle receiver of the electric locomotive remove the tarpaulin protective covers. After that, the electrician is sure to wearing rubber gloves with the train heating key, he opens the lock of the idle receiver on the head car and removes the plug from the receiver, which is inserted into the socket on the electric locomotive using the same key. The plug of the locomotive idle receiver is inserted by the electrician into the socket of the head car. The inclusion of both connections of the car and the electric locomotive is mandatory.

After the electrical connection, the electrician passes the heating key to the driver and from that moment the train is considered to be under electric heating.

4. With what malfunctions in electrical equipment is it forbidden to put cars on trains with high-voltage heating?

It is forbidden to park wagons:

With I/O sockets without covers, without safety springs, with plug connections incorrectly connected;

Unclosed outlet covers;

Without grounding shunts between the car body and the plug, between the box body and the bogie frame and the car body;
