Carbon dioxide fire extinguishers Construction and principles of operation 1. Device consists of a CO2 balloon (-s) with a head and a rubber hose with a discharge muzzle attached to it. Two balloons are interconnected with a collector. When launching the device, the balloons must be placed in a vertical position. A balloon (-s) with console is equipped with wheels and a handle to move the device.

2. To open a balloon, the handle of the head must be removed till the head is placed in the open position. In the device equipped with two balloons (OU 25/2) one balloon must be opened first. The second balloon is opened after CO2 discharge from the first one. Please remember that the handle is blocked with a special safety ring to avoid accidental push on the handle.

Remember to pull the ring before removing the handle! 3. Please unroll the hose and hold the muzzle firmly before the head is opened on the balloon. CO2 will be discharged onto the burning object through the muzzle in the shape of a snow jet.

4. Device can be launched permanently and with intervals by opening and closing the head on the balloon.

Safety rules 1. Balloon with a launch mechanism is a vessel under high pressure with a floating inner pressure – (58 ÷ 150) bar at the temperature of environment from +20°C to +50°C. Therefore charging, repair and inspection of the device must be executed only in the specialised technical service centres. Exploitation of the device in the premises must be in the competence of the person in charge according to “Fire safety rules” No. 82.

If devices are used in severe climatic conditions, exposed to vibrations or gasoline vapour exposure, the current period of probation may be reduced.

2. CO2 volume in the balloon must be inspected not less than once per year. Every five years a certification of CO2 balloon must be executed with a mandatory hydraulic inspection. Along with a hydraulic pressure the resistance and pressure proof of the collector and hose must be executed. 3. Each device must have a manual in the state language attached. 4. When moving devices, please keep the balloon and its head from being hit. 5. Devices must be disposed in premises protecting them from turning over, heating, atmospheric precipitation and heating devices. 6. Exploitation of devices is not allowed without a seal on the safety ring. 7. When extinguishing fire on electric devices under voltage, the muzzle must be kept safe from a burning object not closer than 1 m. 8. Please keep precaution measures, when CO2 is discharged to avoid freezing hands, since the metal parts of the device become cold up to minus 60 ÷ 70°C. 9. Please ventilate premises after the device is used.
