Office Chair Explosion - Buttocks Injuries

Cases of buttocks injuries caused by office chair explosions do exist, and the consequences are severe.

I. Typical Cases

1. 2007 Yantai, Shandong Case: A 68-year-old man sitting on a pneumatic lift chair experienced an explosion, resulting in severe injuries to his buttocks, legs, rectum, anal canal, and small intestine. This incident highlights the risk of multi-site injuries caused by pneumatic lift chair explosions.
2. 2009 Jiaozhou, Shandong Case: A 14-year-old boy suffered an explosion while adjusting a pneumatic chair, with a top rod piercing his buttocks and leading to death from excessive blood loss. This case demonstrates that the force of a pneumatic lift chair explosion can be fatal, especially for vulnerable groups such as teenagers.
3. 2010 Fujian Case: A woman sustained buttocks injuries, along with damage to her rectum and vagina, due to a pneumatic lift chair explosion. This incident further illustrates the potential harm that pneumatic lift chair explosions can cause to the female reproductive system.
4. 2015 Xiamen Case: Miss Liu was surfing the internet at home when her lift chair suddenly exploded, propelling screws and small washers from the chair into her buttocks with great force. This case reveals that internal components of a pneumatic lift chair can become high-speed projectiles during an explosion, causing secondary injuries.

II. Causes of Explosions

The root cause of pneumatic lift chair explosions lies in the substandard quality of the pneumatic rods used in the products. Some companies, aiming to reduce costs, cut corners on key components, leading to破裂 (rupture) or explosions of the pneumatic rods under pressure. Once a pneumatic lift chair explodes, the force it generates is enormous; the force from 24 units of air pressure can at least penetrate six density boards, and it can instantly pierce through human flesh.

III. Preventive Measures

To avoid similar incidents, consumers should choose reputable brands and channels when purchasing pneumatic lift chairs to ensure reliable product quality. Additionally, during use, they should avoid frequently adjusting the air pressure and regularly inspect the condition of the pneumatic rods, replacing them promptly if any abnormalities are detected.
