Fire is the worst disaster. If during floods, earthquakes there is still hope that something can be saved, then during fires there is often nothing to save. Unfortunately, casualties during fires are not uncommon. Therefore, lately much attention has been paid to fire safety, mainly for places where a large number of people, especially children, accumulate.
Carbon dioxide fire extinguishers - this is one of the most reliable means that can prevent a fire. Now they are equipped with buildings of various institutions, they should be in cars, buses and minibuses.
A carbon dioxide fire extinguisher consists of a cylinder filled with carbon dioxide (CO) in liquid form, 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 charged liquid is 5 kg; volume - 6-7 liters; a jet from a cylinder hits a distance of three meters within 10 seconds; total weight of the tank with a gas station 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 that are energized, even high voltage. They can be used for the 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 entering into a reaction with combustible substances, will increase the area of the fire. 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 then effective when the fire is small and can be quickly destroyed. If the fire began to spread over a large area, then before you start to extinguish it, you need to call the fire department, and then make a decision, fight the fire or save yourself and others.
Carbon dioxide fire extinguishers are, in fact, filling cylinders, they must be handled with caution. Do not disassemble, knock on them with sharp objects. Like other containers with gas, they cannot be kept near heating appliances; overheating must not be allowed. Explosion may occur. Components 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 affixed with a label that lists the main parameters: weight, volume, date of refueling and, most important,
shelf life. It is mainly 5 years old. At the end of their expiration dates, fire extinguishers must be inspected and refilled.
If you ever need to use carbon dioxide fire extinguishers, you should know how to do it right: you need to break the seal, point the hose at the fire and press the lever. When using, it must be taken into account that the jet is under pressure and the fire extinguisher gives a return. This can cause panic in an untrained person and affect the extinguishing of the fire.
