The Office Chair Broke Underneath

If the office chair breaks underneath, it should be immediately stopped from being used, and the cause should be investigated and safety measures taken to avoid potential risks.

Analysis of Breakage Causes

1. Fatigue Failure: Long-term repeated loading can cause the internal structure of the material to gradually fatigue, eventually exceeding the material's strength limit and leading to breakage. This is a common cause of office chair breakage, especially for chairs with a long service life or poor quality.
2. Quality Issues with the Pneumatic Rod: For pneumatic lift chairs, if the pneumatic rod has a thin wall, poor sealing, insufficient purity of the inert gas, or abnormal pressure, it may lead to high-risk hazards such as explosions. Additionally, the absence of an explosion-proof steel plate increases safety risks.
3. Unqualified Products: Some office chairs on the market fail to meet standards in terms of structural safety and base static load capacity, indicating potential safety hazards in the chairs themselves, such as thin or weak metal five-star feet, which are prone to breakage during daily use.

Measures After Breakage

1. Immediate Cessation of Use: Once an office chair breakage is detected, it should be immediately stopped from being used to avoid personal injury caused by further damage or collapse of the chair.
2. Check the Pneumatic Rod (if applicable): For pneumatic lift chairs, special attention should be paid to the quality of the pneumatic rod. Check for air leaks, deformation, or abnormal sounds in the pneumatic rod, and confirm whether an explosion-proof steel plate is installed.
3. Evaluate Other Components: Check whether the base, five-star feet, and other components have broken due to quality issues or long-term use. If other components are found to be damaged, they should be addressed together.
4. Safe Disposal: Move the broken office chair to a safe area to prevent others from misusing it. If the chair cannot be repaired, it should be properly discarded or handled by a professional recycling agency.

Preventive Measures

1. Choose Qualified Products: When purchasing an office chair, choose reputable brands and channels to ensure that the product meets relevant safety standards.
2. Regular Inspection and Maintenance: Regularly inspect various components of the office chair, such as the pneumatic rod, base, and five-star feet, to ensure they are intact. If abnormalities are found, they should be repaired or replaced promptly.
3. Avoid Overloading: Do not exceed the rated load capacity of the office chair to avoid long-term exposure to excessive loads that can cause material fatigue.
