Fire - this is a terrible accident, which results in loss of property, and sometimes life. Naturally, any fire center should be eliminated. For this purpose, the fire extinguisher "OU-3" may come up.
This device works very simply.The fire extinguisher "OU-3" acts due to the expulsion from the balloon of carbon dioxide, which is in it under pressure. After the bolt trigger is triggered, the carbon dioxide along the siphon tube advances to the bell. If it is in a calm state and has a liquefied appearance, it turns into gas at the moment of action.
A special feature of this fire extinguisher is instantaneous cooling of the combustion zone. In addition, the gas-air medium, which is blazing, is rapidly diluted with inert CO2. As a result, combustion stops.
The fire extinguisher "OU-3" has the following characteristics:
- The length of the jet is 2.1 m.
- The capacity of the flask is 4.3 liters.
- The charge goes for 8 seconds.
- The weight of the device ready for use is 12.5 kg.
- Temperature of use - from -40 to +50 degrees.
- The service life, which is guaranteed by the manufacturer, is 1 year from the date of issue.
The OU-3 fire extinguisher is effective for extinguishing fires where water-based apparatus can not be used.
It is used in the following cases:
1. In museums and galleries, where valuable exhibits are stored, which can be damaged by water.
2. For extinguishing of electrical installations, the voltage in which does not exceed 1000 V.
3. To eliminate fire in trolleybuses, trams, electric trains.
4. To extinguish gaseous, liquid and solid combustible substances.
Use of such a fire extinguisher is possible both indoors and outdoors.
Note that this device has certain advantages:
- Does not leave traces after extinguishing.
- Provides an opportunity to save valuable items that spoil the water.
The only drawback of thedevice is that it can not be used to extinguish those substances that burn even without access to air. Here, carbon dioxide is simply useless.
As for the safety of the application, the carbon dioxide fire extinguisher "OU-3" has some operational requirements:
1. If it is necessary to extinguish an electrical installation that is under voltage, 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.
3. It is not recommended to use the machine if there is no seal on it.
4. During the release of CO2 Do not direct the bell to people, as the gas temperature is -60 degrees.
5. Do not leave the unit in direct sunlight.
6. At least twice a year, check the operation of the device.
Fire extinguisher "OU-3", the characteristics of which are discussed above, should be used strictly according to the instruction:
1. Lift the fire extinguisher to the fire, taking into account the minimum permissible distance.
2. Point the bell to the side where the fire is located, pull out the check and press the handle that actuates the shut-off valve.
3. If the ignition does not occur indoors, try to direct the socket so that the carbon dioxide does not go out against the wind.
4. After extinguishing the device should be taken to refill.
Please note that the fire extinguisher can accumulatethermal stress and static electricity. Try to extinguish the fire so that carbon dioxide does not fall on you, because it has a toxic effect.
That's all the features of the application of the device. Good luck!
