How dangerous is the container for explosive materials?

Concerning the explosion in Ha Dong, many doubts were caused by sawing explosives.

Associate Professor Tran Hong Con - lecturer of Hanoi University of Chemistry said that the cause of the explosion is due to pressure. Cylinders containing liquid gases such as liquid oxygen, nitrogen, and liquid hydrogen have very high compression pressures, and the valve and tank systems are very thick.

On the sidewalk in front of the house number 40, a large hole, more than 2 m in diameter, appears.

When the exhaust is not completely discharged, the saws create a weak spot causing cracking and exploding. Explosion mechanism is caused by pressure . In the event that the gas explodes, oxygen will not cause further detonation, but the hydrogen gas after being released can continue to explode because it also acts with oxygen outside the air.

PGS Con said, oxygen cylinders are mainly used in clinics, hospitals, where people are welding, . If the bottle is not used up, rusty steel makes the scrap buyer can not distinguish the consequences. as above. This major error belongs to the irresponsibility of the seller.

According to this expert, the destructive power, the danger of exploding air bombs depends on the pressure in it. He analyzed, only a balloon containing hydrogen, if accidentally burned fire will cause fire, causing injury. In the case of an oxygen tank exploding, the level is very large.

Liquid gases such as oxygen, hydrogen, nitrogen are all non-toxic gases, and when they are exploded, they cause a physical injury. Due to the pressure, pushing people away or shrapnel splashed into people.

The latest information from Colonel, Doctor Pham Van Tien - Head of the Emergency Department, Hospital 103, said that there are currently 5 people who were taken to emergency here. All are passersby affected by explosion. In it, a minor wound was discharged. The driver of a truck with splashes and another woman with multiple injuries, heavy prognosis is currently treated in active resuscitation. Two other people, a glass-stained person pierced the thigh, a person was stabbed in the head, currently quite heavy.
