Five people, including two police officers, were injured today when a sewer exploded on a car parked in the New York neighborhood of The Bronx.
It is not known what caused the explosion, but the electric company Con.Edison is assessing the damage, says the ABC.
The explosion occurred at 7:30 am, local time, without causing cuts in the neighborhood electric service, in the Melrose section of the South Bronx.
According to Biobiochile, the explosions in New York have occurred several times, some due to accumulated vapors or explosions of electrical equipment. We extract several:
On the 19th of July this year an 86-year-old oil pipeline exploded opening a 9-meter hole on East 21st Street in New York, but no one was hurt. However, in 2007, an accident of the same style near the Grand Central Terminal killed one person and injured dozens.
Con.Edison has been forced to pay millions of compensation, so it claims to do the relevant security maintenance in the old pipeline system.
"We continue to study changes in procedures and equipment improvements that can further increase security," said Dr. Dr Allan Drury.
It is expected that accidents like those of the last few years will not be repeated, and both tourists and locals will continue to enjoy the particular steam that has become part of the charm of the city.
Why does steam get out of New York sewers?
The New York steam became something characteristic of the city, almost as much as the skyscrapers and the classic yellow taxis; It is part of the life of New York and is a very curious fact for the thousands of tourists who visit the Big Apple.
The New York steam system created in 1880 is the largest in the world. According to the New York Times, it has 105 miles of pipes running throughout the city supplying steam for heating, hot water and refrigeration to 2,000 buildings.
The system is called Consolidated Edison and, according to the BBC chain, operates with four steam stations and two that generate steam and electricity at the same time.
It is also very useful for sterilizing surgical instruments in hospitals, washing dishes in restaurants, ironing in dry cleaners or simply heating museum rooms.
Without that vapor network, perhaps the outline of the city that mixes old and modern skyscrapers would be different: "They would never have built these buildings, because they could not heat them," said Dan Holohan, known for writing 22 books on the subject . with BBC World.
According to Telemundo, steam supplies energy mainly to large buildings, including the Grand Central Terminal, the United Nations headquarters and the Empire State Building.
For example, the World Trade Center (540 meters high) is connected to steam. "The size of a boilers plant for such a large building should be monstrous," said Steve Mosto, owner of Mosto Technologies, another company that also offers steam systems for commercial buildings.
The trend, according to Crain in New York, was considered a necessity in the 80s, and was much appreciated as it reduced pollution in the big city, a situation that from that moment began to affect others big cities like London.
However, the boilers driven by natural gas are the new trend, the engineers of New York point out that 72.9% of the buildings prefer the new boilers, while only 10% depends on the consolidated technologies Edison and Mosto. The hot water boilers have the second place with 13%, the remaining 5% corresponds to the rest of the heating systems.
And why is steam usually seen on the surface?
These are steam leaks, the same ones that run through the pipes escape the surface through minichimeneas & # 39; strategically positioned so as not to obstruct the view of passersby. Run away in the sewers, but to a lesser extent.
"They are leaking pipes that need to be repaired but they are not dangerous, you do not need to do it right away," says Allan Drury, a Con.Edison spokesperson.
Despite the great virtue of providing heating to high-rise buildings, high-rise buildings, the system also has its shortcomings.
NY-Engineers also emphasizes that steam hoses are not usually the best choice. The response time is usually much slower and it is difficult to adjust the temperature, which is usually very simple when using the most modern systems.
In addition, they often promote the system as "environmentally friendly", but according to Crain of New York, Con.Ed, which has largely eliminated the need for chimneys burning coal or wood, it has burnt 10 million liters of fuel last year, turning the company into one of the city's largest oil consumers.
