The object that accompanies us day and night, maybe we don't understand it so much. Such as office chairs, office chairs of poor quality will explode.

Is this real?

It is true!

The office chair exploded and the scene was messy

Earlier, some netizens posted online that their colleague's office chair exploded.

Some netizens posted online that their colleague's office chair exploded during work. Fortunately, when the colleague went to the bathroom, there were no injuries.

But judging from the photos on the scene, it was shocking. The black lift chair that is common in the office is broken into two parts from the rotating shaft, and the wheels of the lift chair also fall off and are scattered on the ground. Even the computer next to the office chair was not spared, and the main box was hit and cracked.

Fortunately, there was no one on the office chair at the time, otherwise the consequences would be unimaginable.

There have also been reports of a woman blowing her hair while sitting on an office chair at home. The office chair exploded, and her abdomen and buttocks were injured and her injuries were serious. The younger brother said the explosion was very, very loud.

How can an office chair explode?

If you look closely, you will find that most office chairs in the office are "air pressure type", that is, the height of the seat is adjusted by the air pressure rod.

Under normal circumstances, the gas pressure rod is filled with high purity inert gas nitrogen. When a person is sitting on a chair, although the squeezing pressure of nitrogen is increased, it is still within the limit and no problems will occur.

But some bad merchants, to save money, will use inferior air pressure rods, these inferior air pressure rods will have many problems, such as poorly filled materials, insufficient nitrogen purity...

When encountering high temperatures or frequent lifting of office chairs, the pressure in the pneumatic rod will suddenly increase, and it is easy to explode.

A researcher once experimented, throwing sandbags of the same weight to three office chairs in a two-storey place. Of these three office chairs, one was produced by a regular manufacturer, one was produced by a manufacturer without qualification, and the other was a used office chair that had been in use for 30 years.

When the sandbag was thrown down, the second-hand office chair exploded. The inferior office chair was exploded and caught fire. Only those produced by regular manufacturers, although the shaft is broken, but did not explode.

Pay attention to the purchase and use of office chairs

Therefore, when we buy office chairs, we must buy them from regular merchants, and we should never buy inferior office chairs for the sake of cheapness.

When using office chairs, we should also pay attention to the following points:

• Do not adjust and rotate the chair repeatedly

Many people like to adjust the chair repeatedly when they are sitting in an office chair. Over a long period, the pneumatic rod will be subject to uneven wear and tear, burying hidden safety hazards.

• Do not disassemble the office chair at will

Some people think that the gas in the office chair is very dangerous, they will disassemble the office chair and release the gas. This approach is undesirable. Don't disassemble the office chair if you are okay, if you want to repair it, you can ask a professional to help.

• Regular inspection and maintenance of office chairs

Any item has its own service life. For safety reasons, the office chair should be regularly checked. If the office chair is cracked or loose, it must be repaired and replaced in time to avoid potential safety hazards.
