Fire is the most terrible disaster. If during floods, earthquakes there is still hope that something can be saved, then during fires there is often nothing to save. Unfortunately, human casu alties are not uncommon in fires. Therefore, in recent years, much attention has been paid to fire safety, mainly in places where a large number of people, especially children, accumulate.
Carbon dioxide fire extinguishers are one of the most reliable means of preventing a fire. Now buildings of various institutions are equipped with them, they should be in cars, buses and minibuses.
A carbon dioxide fire extinguisher consists of a cylinder filled with liquid carbon dioxide (CO) pumped under high pressure. The kit also includes a hose for directing the jet and a holder with which the fire extinguisher is attached to the wall. Most often, organizations use a carbon dioxide fire extinguisher OU-5. It has the following characteristics: the weight of the filled liquid is 5 kg; volume - 6-7 liters; a jet from a balloon hits a distance of three meters for 10seconds; the total weight of the cylinder with filling is 14.5 kg. Those fire extinguishers that are used in our country can function in severe frosts.
Carbon dioxide fire extinguishers are used to extinguish equipment and objects under voltage, even high-voltage ones. They can be used in case of ignition of combustible substances. It is important to remember that electricity and flammable substances (gasoline, diesel fuel, oil) should never be filled with water. Water instantly conducts current, and reacting with combustible substances, it will increase the fire area. And the foam, which is formed from carbon dioxide, simply stops the access of oxygen to the fire, and it goes out. But the use of a fire extinguisher is effective when the fire is small and can be quickly destroyed. If the fire began to spread over a large area, then before starting to extinguish it, you must call the fire brigade, and then make a decision whether to fight the fire or save yourself and others.
Carbon dioxide fire extinguishers are, in fact, cylinders with filling, you need to handle them quite carefully. Do not disassemble, knock on them with sharp objects. Like other gas containers, they should not be kept near heating devices, and overheating should not be allowed. There may be an explosion. The components found in fire extinguishers are toxic to humans, this time. Foam eats into any surface, it is very difficult to wash it, these are two.
Fire extinguishers must be sealed, they are glueda label that lists the main parameters: weight, volume, date of refueling and, most importantly, expiration date. Basically it is 5 years. At the end of their expiration date, fire extinguishers should be checked and refilled.
If you ever need to use carbon dioxide fire extinguishers, you should know how to do it correctly: you need to break the seal, point the hose at the fire and press the lever. When using it, one must take into account that the jet hits under pressure, and the fire extinguisher gives a return. This can cause panic in an unprepared person and affect the extinguishing of a fire.
