Fireman

These people are needed only when disaster strikes. And the reason for this, including these myths about her.

Firefighters are sleeping at work. This myth has many different options - "asleep like a firefighter", "firefighters overslept" and so on. This opinion was relevant when firefighters served for 25 years, and they lived right where they worked - in fire departments. There they ate and slept, raised their children and ran the household. Then the fire service was even harder than today - they worked in one shift. The rise was at 5 am, and the working day lasted 15-16 hours. In the morning, firefighters read a prayer, then cleaned the horses and cleaned the yard. And in between going to work, they had a rest, being, in fact, at home. It was then that people noticed the sleepy tired firefighters, which became the basis for the myth.

Currently, the firefighters service starts at about 8-30 and lasts the whole day. After that, people rest for three whole days. The daily routine does include sleep. But if a call for a fire comes, then there is no need to talk about any rest. But every day, dozens of messages about fires, or even just about smoke and fires, come to number "01". Every day, firefighters study and train, they have to go to the burning of grass, garbage, forests, even to burnt food on the stove, and there are simply false calls. So to say that firefighters sleep at work is no longer necessary.

Firefighters arrive without water. This is often said by journalists reporting from the scene or ordinary people who are dissatisfied with the speed of the rescuers. In fact, this myth can be quite reasonably refuted. To extinguish fires, tank trucks based on ZIL-130 are usually used. The volume of such a container is 2350 liters. If at least one barrel, while not the most powerful, works in a fire, then all the water from the tank will go out in 7.5 minutes. If there are two trunks, or one powerful, then the brought water will be enough in general for 5-6 minutes to extinguish the fire. Therefore, as soon as the brought supply of water ends, the tanker must stand on the source of the liquid. And so that there are no interruptions and hitch, the first car that arrives consumes a supply of water to extinguish the fire, and the second, even with a full tank, immediately goes to the source to ensure uninterrupted supply. That is why it seems to people that the car arrived without water, immediately going to the gas station. But those who simply do not delve into the organization of the work of firefighters think so. Statements that firefighters go to the call without water not only offend representatives of the honorable profession, but also simply discredit it.

Firefighters can go to a fire for half an hour. There is Federal Law No. 123-FZ entitled “Technical Regulations on Fire Safety Requirements”. It clearly establishes the timing of the arrival of fire departments at the scene of the disaster. For urban areas it is 10 minutes, and for rural areas - 20 minutes. If we assume that the firefighters arrived only after half an hour, then we can calculate that the area of ​​the fire will be up to 200 square meters. It is important to ask the question, when was the fire reported at all and how long did it develop freely. It is known that in the first 10 minutes the fire spreads 2 times slower, which is why it will be much easier to extinguish the fire during this time.

When a fire engine drives to work, water can flow out of a leaky cistern. In fact, there is a water level control pipe in the tank. It is located inside the tank and is necessary to release air when filling the tank from a conventional water supply network. As soon as the tank is full, water is poured out of the control pipe. This makes it clear that the tank is full. So if water splashes out at a fire engine while driving, this does not mean a leaky tank, but about its one hundred percent filling with water.

Firefighters will carefully open the jammed door. Often people are asked not to harm their jammed doors. But the State Fire Service is needed primarily for extinguishing fires and carrying out emergency rescue operations. Ensuring the safety of doors is clearly not a priority. And firefighters do not have equipment for opening locks. There that usually the door is either opened with a crowbar or the lock is cut out with a "grinder".

Firefighters can pull out a vehicle stuck in the mud. Firefighters' equipment is provided for extinguishing fire. Therefore, cars are designed specifically for the transport of water and special equipment. As a result, fire engines have a lower clearance than other vehicles. If assistance is provided to pull other vehicles out of the mud, then there is a risk of damaging the expensive equipment of specialized vehicles. And firefighters usually go to a disaster that threatens people's lives. There is no time to help unlucky motorists.

Firefighters can pump water out of a flooded cellar. The fire trucks are equipped with a PN-40 pump. It is designed to release a very powerful jet of water. For this, an impeller is used inside the pump, and it itself has a snail aluminum casing. And the difference between sanitary cleaning vehicles with a vacuum suction principle is that dirty water and small stones quickly wear out the impeller. As a result, one pumping out of the cellar can lead to a rather expensive repair of the pump and the unusability of the entire fire engine.

Classic fire poles are already banned. The appearance of the pole at the fire station was not accidental. On the night shift, lifeguards are in the bedroom or the rest room. With the arrival of a call, they rush to the cars with all their might. And to get into the garage from the upper depot, it will be safer to go down there on the pole than to stomp on the steps with heavy shoes. After all, in a hurry, you can dislocate your ankle. In some places they decided to abandon the stairs and poles altogether, and to build a one-story depot. This practice has become standard, but in densely built-up areas with high land values, several storey depots continue to exist. They still put the poles there. And this myth owes its appearance to publications in English newspapers in 2006. But it was just about the reconstructed depot without poles, which just appeared in Plymouth. The tabloid press inflated a sensation from this, allegedly the poles pose a threat, which was the reason for the refusal to use them. But there has never really been a ban.

Fires are extinguished with water. It would seem that what could be natural - extinguishes the fire with water. In fact, firefighters have many fire extinguishing agents in their assortment today. These are foam, carbon dioxide, water vapor, and nitrogen.
