Novah Office Chair Explosion

Currently, no direct evidence has been found indicating that there have been explosion cases of 'Novah office chairs'. However, the explosion risk of pneumatic lift office chairs is not related to the brand but mainly depends on whether the quality of the pneumatic rod and the safety design meet the standards.

Core Reasons for Pneumatic Lift Chair Explosions

Explosion accidents of pneumatic lift chairs are mostly caused by low-quality pneumatic rods. For example, in cases in Zhoushan, Zhejiang in 2007, Jiaozhou, Shandong in 2009, and Anhui in 2017, the root causes of the explosions included the following:

1. Thin Wall of the Pneumatic Rod: To reduce costs, low-quality pneumatic rods have insufficient wall thickness and cannot withstand the impact of high-pressure gas. They are prone to breakage under frequent lifting or high-temperature environments.
2. Insufficient Purity of Inert Gas or Replacement with Compressed Air: Qualified pneumatic rods should be filled with high-purity inert gases such as nitrogen to suppress internal oxidation and pressure fluctuations. Low-quality products, however, may be filled with compressed air, which is chemically active and prone to reacting with the rod wall, leading to abnormal pressure increases.
3. Absence of Explosion-Proof Steel Plate: The explosion-proof steel plate is a key safety device with a thickness of at least 2 millimeters. It can block fragment splashes in the event of a pneumatic rod explosion, reducing the risk of injury. If this device is missing, explosion fragments may directly impact the human body, causing serious consequences.

Safety Recommendations for the 'Novah' Brand

To confirm whether 'Novah' office chairs have similar risks, you can check through the following methods:

1. Check the Purchase Channel: Prioritize official brand flagship stores, authorized dealers, and other legitimate channels. Avoid purchasing products from unknown sources to reduce the risk of low-quality pneumatic rods being mixed in.
2. Verify Pneumatic Rod Safety Standards: Request the merchant to provide a test report for the pneumatic rod to confirm whether key indicators such as its high- and low-temperature resistance (e.g., no leakage or deformation in environments ranging from -20°C to 60°C) and the thickness of the explosion-proof steel plate (≥2 millimeters) meet the standards.
3. Observe Product Details: Legitimate products usually have safety certification marks (such as SGS, BIFMA, etc.) on the pneumatic rod or base, and the lifting process is smooth without abnormal noises. If you find scratches, rust, or lifting jams on the surface of the pneumatic rod, there may be quality hazards.
