Instructions for use of carbon dioxide fire extinguisher OU 3. Carbon dioxide fire extinguisher, portable. Instructions for use

A fire is a terrible incident that results in the loss of property, and sometimes life. Naturally, any source of ignition should be eliminated. An OU-3 fire extinguisher may be suitable for this.

The principle of operation of the device and its technical characteristics

This device works very simply. The fire extinguisher "OU-3" operates by displacing it from the cylinder, which is under pressure in it. After the shutter trigger mechanism works, carbon dioxide moves through the siphon tube to the socket. If it is in a liquefied state at rest, then at the moment of action it turns into a gas.

A feature of such a fire extinguisher is the instantaneous cooling of the combustion zone. In addition, the gas-air environment that blazes is quickly diluted with inert CO2. As a result, combustion stops.

Fire extinguisher "OU-3" has the following characteristics:

Jet length - 2.1 m.

The capacity of the flask is 4.3 liters.

The charge comes out in 8 seconds.

The weight of the device ready for use is 12.5 kg.

Use temperature - from - 40 to +50 degrees.

The term of operation, which is guaranteed by the manufacturer, is 1 year from the date of issue.

Scope of application

The OU-3 fire extinguisher is effective for where water-based fire extinguishers cannot be used.

It applies in the following cases:

1. In museums and galleries where valuable exhibits are stored that can be damaged by water.

2. For extinguishing electrical installations, the voltage in which does not exceed 1000 V.

3. To eliminate fire in trolleybuses, trams, trains.

4. For extinguishing gaseous, liquid and solid combustible substances.

This fire extinguisher can be used both indoors and outdoors.

Advantages, disadvantages and precautions

Note that such a device has certain advantages:

Leaves no traces after quenching.

The only drawback of the device in question is that it cannot be used to extinguish those substances that burn even without air. Here carbon dioxide will be simply useless.

As for the safety of use, the carbon dioxide fire extinguisher "OU-3" has some operational requirements:

1. If it is necessary to extinguish an electrical installation that is energized, then you should not approach it closer than one meter.

2. Do not recharge or repair the device yourself. For this, there are special service centers.

4. Do not point the bell at people during the release of CO 2, as the temperature of the gas is -60 degrees.

5. Do not leave the device in direct sunlight.

6. At least twice a year, check the operation of the device.

Instructions for use

The OU-3 fire extinguisher, the characteristics of which are discussed above, must be used strictly according to the instructions:

1. Bring the fire extinguisher close to the source of fire, observing the minimum allowed distance.

2. Point the bell in the direction where the fire is located, pull out the pin and press the handle that activates the device.

3. If the fire did not occur indoors, then try to direct the socket so that carbon dioxide does not come out against the wind.

4. After the extinguishing is completed, the device should be taken for refueling.

Keep in mind that a fire extinguisher can build up heat stress and try to extinguish the fire in such a way that carbon dioxide does not fall on you, as it has a toxic effect.

That's all the features of the application of the presented device. Good luck!

Fire extinguishers OU3 and OU5- portable CO² (carbon dioxide) fire extinguishers.

Fire extinguishers OU3 and OU5 are designed to extinguish the fire of various substances, the combustion of which cannot occur without access to air, fire on electrified railway transport, electrical installations under voltage not exceeding 10 kV, fire in museums, art galleries and archives, widespread use in office premises with office equipment, and also in the residential sector.

Carbon dioxide fire extinguishers are warehouse position and you can easily buy carbon dioxide fire extinguishers we have.

fire extinguishers CO2 ( carbon dioxide) OU-3 and OU-5 correspond to TU 4854-212-21352393-99 and are recognized as fit for operation.

• Working pressure in the fire extinguisher body (calculated) at a temperature of 20`C 5.8 MPa.
• The extinguishing agent is carbon dioxide (CO2) according to GOST 8050-85.

Fire extinguisher consists of the following parts:

• high pressure steel cylinder;
• shut-off and starting device (LPU), threaded into the neck of the cylinder, equipped with a carrying handle and a lever for starting and interrupting the supply of fire extinguishing agent (OTV), as well as a check to prevent unauthorized operation of the fire extinguisher and a membrane that protects against excess pressure inside the cylinder over admissible;

Video review of OU-3

1. "CO2 fire extinguisher OU-3 (h) (B, C, E)"- works on the principle of exclusion of oxygen in the combustion chamber.
2. Due to the fact that after use the carbon dioxide fire extinguisher "OU-3" does not leave marks, it is widely used at facilities where there is a risk of short circuit, for example, at substations, industrial enterprises, industrial warehouses.
3. Carbon dioxide fire extinguishers do an excellent job of igniting combustible gases, paints, oils, fuels, so gas stations are equipped with them.
4. Using the OU-3 carbon dioxide fire extinguisher, you do not need to worry about dust or clogging of the room, after drying there are no traces left.
5. "CO2 fire extinguisher OU-3 (h) (B, C, E)" are ideal for libraries, hospitals, schools. The storage range of a carbon dioxide fire extinguisher is from -40C to +50C, which is perfect for our latitudes, and the service life of the fire extinguisher is 10 years.

Instruction

1. "Carbon dioxide fire extinguisher OU-3 (h) (B, C, E)" copes with fire due to the displacement of the carbon dioxide charge, under the influence of its own excess pressure, which is created in the fire extinguisher.
2. Carbon dioxide is in a cylinder under a pressure of 5.7 MPa (58 kgf/cm2) at an ambient temperature of 20°C.
3. The maximum working pressure in the fire extinguisher cylinder at a temperature of +50°C should not exceed 15 MPa (150 kgf/cm2).
4. When opening the shut-off-starting device (LPU), the charge of carbon dioxide through the siphon tube enters the socket. When this occurs, the transition of carbon dioxide from a liquefied state to a solid (snow-like) state, accompanied by a sharp drop in temperature to minus 70°C.
5. The fire-extinguishing effect of carbon dioxide is based on cooling the combustion zone and diluting the combustible vapor-gas-air medium with an inert (non-combustible) substance to concentrations at which the combustion reaction stops.
6. To bring the "OU-3" into action, it is necessary to pull out the pin.
7. Direct the fire extinguisher bell at the fire from a distance of 3 meters from the windward side.
8. With a hand, press the handle of the locking device (LPU), carbon dioxide is released under high pressure (fire extinguishing agent (OTV)).
9. While using the "OU-3", it is necessary to hold the fire extinguisher socket by the plastic part, otherwise there is a risk of frostbite.
