How was the old man against 'Ms. fire'?

Since humans began to use wood to build houses instead of heavy stone materials, fires also began to stalk them.

Earshearts have always been an obsession for residents living in densely populated cities, to the extent of 1254 in France, King Saint Louis allowed residents to patrol every night to watch for fires.

The first professional fire brigade in human history was born in 115 BC.

Seeing the city of Rome without a fire fighting team, a rich man named Marcus Licinius Crassus established a firefighting force of 500 people.

The interesting thing is that Crassus has enriched with this initiative, because every time there is a fire, he will negotiate the price to fire with the misery of the house being burnt.

If an agreement is reached on costs, the "private firefighters" are just starting to work, otherwise leaving fire. After the fire, Crassus again asked to buy with the house that had burned down with cheap price.

It was not until the 60s of the 1st century that Emperor Nero founded a professional fire brigade for Rome.

In England, after the fire in 1666 in London, insurance companies had to pay huge sums of money.

Since the state does not organize a professional firefighting team, insurance companies have established their own fire brigades to avoid the risk of bankruptcy when a big fire occurs like last time. The only thing is that they only fire those who buy their insurance.

First fire fighting equipment

The first fire-fighting water pumping device was born in the city of Alexandria (Egypt) in the 2nd century BC. But this invention was forgotten until the 16th century, when people "reinvented" this device.

At this time, fire extinguishing equipment was very rudimentary: using water pump by hand and no water pipes go far.

It was not until the late 17th century that there was an important breakthrough in fire hydrant pumping equipment, the two inventors Hans Hautsch (Germany) built the suction-pushing pump and Jan Van der Heyden (Netherlands) made it Mobile fire hydrant.

The first self-propelled fire truck with a steam engine was born around the middle of the 19th century, but not very popular. Then, with the introduction of internal combustion engines, fire engines have new engines everywhere.

From the 1970s onwards, with many inventions in the fields of metallurgy, water pumps, motors, power systems and drives, as well as effective anti-tilting technology solutions, fire engines equipped with engines Large capacity water pump and lift have become indispensable devices in human life.

Scientists began to manufacture a variety of specialized new-generation fire engines with different equipment used in the following cases: fire fighting civil construction works, aircraft fire fighting (in the yard flying) and ship fire fighting.

For fire fighting in modern buildings with a few dozen floors or more out of reach of pumps and ladder cars (up to 30m), it is necessary to use the stairs for the fire brigade alone, combined with the internal fire fighting system. The set of buildings, sometimes used to fire helicopters.

In the future, with dense traffic in large cities, how fire trucks can move smoothly in tight urban roads, crowded vehicles are a major difficulty for the industry. fire fight.
