The device and principle of operation of a fire extinguisher

Carbon dioxide fire extinguisher OU-5 is a high-pressure injection fire extinguisher with a charge of liquid carbon dioxide (according to GOST 8050-85), under saturated vapor pressure. The capacity of the OU-5 case is 6.7 liters, the mass of the charge is 5 kg. It is designed to extinguish a fire object within 8 seconds with a jet length of 3 m.

The operation of the OU-5 fire extinguisher is based on the displacement of the carbon dioxide charge under the action of its own excess pressure, which is created when the fire extinguisher is filled. Carbon dioxide is in a cylinder under a pressure of 5.7 MPa (60 kgf/cm2) at an ambient temperature of +20°C. The maximum working pressure in the cylinder at a temperature of +50°C should not exceed 14.7 MPa (150 kgf/cm2). The fire-extinguishing effect of carbon dioxide is based on cooling the combustion zone and diluting the combustible vapor-air medium with an inert (non-combustible) substance to concentrations at which the combustion reaction stops.

Operation, maintenance and safety instructions

The OU-5 fire extinguisher must be placed in easily accessible and visible places where precipitation, direct sunlight or heating of the fire extinguisher above 50 ° C is excluded.

Operation of a fire extinguisher without a check and a seal from the manufacturer or the organization that reloaded the fire extinguisher is not allowed.

When extinguishing live electrical equipment, it is not allowed to bring the socket or body of the fire extinguisher to open live parts with a voltage of 10 kV closer than 2 meters.

Care must be taken when discharging the carbon dioxide charge from the bell, as the surface temperature of the socket with the hose is reduced to -70 °C.

After use, the fire extinguisher should be sent for recharging as soon as possible, replacing it with the same type of backup fire extinguisher.

The fire extinguisher must be weighed annually during initial installation and at least once a year. Permissible amount of carbon dioxide charge leakage - no more than 50 g per year.

Recharging and maintenance of the fire extinguisher must be carried out at least once every 5 years by specialized organizations licensed for this type of activity, using a special charging station.

Re-examine the cylinder after 10 years.

• operation manual combined with a passport for a fire extinguisher - 1 pc.

Additional Information

In the event of a fire, it is necessary to pull out the pin, direct the socket towards the fire, press the locking device lever and start extinguishing the fire.

Currently, one of the most common, convenient and highly effective devices for extinguishing fires is the OU-5 fire extinguisher. The model is intended for extinguishing materials that ignite when exposed to oxygen, some flammable liquid substances, as well as electrical installations operating under up to 10 thousand volts.

Due to its compact size and ease of use, the OU-5 fire extinguisher is often used in museums, archives, art galleries, and other premises where flammable materials are stored.

Purpose

Fire extinguishers OU-5 are indispensable for extinguishing papers, combustible gaseous substances, flammable liquids, electronics and electrical equipment. At the same time, the use of devices of this type turns out to be ineffective when it is necessary to suppress flames during the ignition of solid materials, as well as substances capable of sustaining combustion in the absence of access to oxygen.

Fire extinguisher OU-5: characteristics

The suppression of fires with a fire extinguisher is based on the cooling of objects and substances that are in the combustion zone. At the same time, it is diluted with inert, non-combustible substances of high concentration, which create conditions for stopping the combustion reaction.

Fire extinguishers OU-5 technical characteristics have the following:

• weight - 15 kg;
• ejection time of inert non-combustible substances - 8 seconds;
• jet length - 3 meters;
• operating temperature - in the range from 5 to 50 ° C;
• extinguishing agent - carbon dioxide;
• - more than 5 years with annual maintenance and charge mass control.

Application features

The OU-5 fire extinguisher is activated by removing the holding sealed checks. The socket of the device is directed towards the source of ignition. At the same time, contact of exposed skin with the active substance should be avoided, since when it is released, its temperature drops to a dangerous limit of 60 to 70 degrees below zero.

The fire extinguisher is activated by releasing the starting, locking device - the lever, which must be opened to failure. Using the same lever, you can interrupt or completely stop the supply of carbon dioxide substances.

General terms of use

Before using the OU-5 fire extinguisher, it is necessary to determine the type of fire in order to understand how suitable and effective this model will be in the existing conditions.

It is necessary to suppress ignition sources by directing the fire extinguisher socket from the windward side, gradually moving into the depths of the flame. When extinguishing liquid flammable substances, the bell should first be directed to the front edge of the hearth, and not to an open flame, moving towards the center as the fire is suppressed.

Flammable vertical surfaces, as well as flammable liquid pouring from a height, must be extinguished from top to bottom. In this case, if possible, it is better to use several devices of this type at the same time.

Do not bring the OU-5 (3) fire extinguisher, which makes it possible to extinguish electronics and burning electrical installations, closer to electrical appliances at a distance closer than that indicated on the model label.

When you need to make sure that the flame does not flare up again, and in no case turn your back to the fire. Using a fire extinguisher, you should send it to recharge.

Model OU-5 is subject to regular, periodic leak testing, which should be performed at least once every six months. Weight is also subject to verification - it must comply with the standards specified in this fire extinguisher model.

If the weight of the cylinder during the measurement is less than the prescribed indicators according to the technical specifications or the service life of the cylinder is exceeded, the fire extinguisher must be sent for maintenance. If necessary, it is recharged by a service station specialist.
