Perhaps a little more for readers to visualize the danger always lurking firefighters like. If someone still thought that a house made of bricks, a ceiling of concrete like that, there was a fire, it only burned furniture, a house without any problem was a very dangerous mistake. The house cannot be burnt, but it may collapse. Is it because a brick or concrete wall is only able to withstand temperatures at a certain level. If the temperature is too high, the iron in the concrete will become soft, unable to withstand traction. Brick walls are burnt lime, not able to compress anymore. This, professional word is called losing cohesion. With the weight of all that construction materials, the house will collapse immediately.
A very specific example is the disaster that occurred at the World Trade Center in New York, USA in the September 11, 2001 terrorist attacks. More than 300 American firefighters were killed when the rescue work at the right time, seemingly eternal by reinforced concrete, collapsed without warning. The aircraft’s fire, fueled by the aircraft, crashed into it, generating tremendous heat, burning all the most durable structures. The tower has collapsed because of its massive size.
For professional firefighters, they can also participate in rescue in specific situations when meeting victims, but the main task is to put out the fire. As mentioned above, currently Hoan Kiem Room has 4 fire engines. These are all newly equipped, new and good vehicles. Each car like that carries more than 4m3 of water. If using a 7 liter / second type steering wheel, it can be pulled and sprayed to the 15th floor. In case of deep lane with too long distance, will have to deploy the pump station to increase the spraying force.
