Office Chair Electric Leakage

If an office chair has an electric leakage, it should be immediately stopped using and inspected and repaired to avoid the risk of electric shock. Here are the specific handling steps:

Step 1: Cut off the power and stop using
For electric office chairs, unplug the power cord or turn off the power switch as soon as possible. Do not continue to use or touch the chair to prevent electric current from passing through the human body and causing electric shock injuries. Although non-electric office chairs have no power supply lines, they should also be immediately stopped using if their metal parts have an electric leakage to avoid dangers caused by static electricity or electric leakage.

Step 2: Investigate the cause of the electric leakage
Common causes include:

1. Aging and damage of wires: The outer layer of the electric chair's wires may crack due to long-term friction or aging, exposing the internal copper wires and causing electric leakage.
2. Loose internal wiring: The wiring ports of electric adjustment components (such as motors and control modules) are loose, resulting in poor contact and short circuits.
3. Damage to electrical components: Core components such as motors and control modules may malfunction due to water ingress, overheating, or aging, causing the live parts to be exposed.
4. Static electricity accumulation: The metal parts of non-electric chairs may generate and continuously accumulate static electricity due to moisture, dust accumulation, or lack of grounding.
5. External equipment failure: For example, for advertising board office chairs, if the low-voltage conversion box rusts and rainwater seeps in, the circuit connected to the chair may have an electric leakage.

Step 3: Make targeted repairs

• Damaged wires: After cutting off the power, tightly wrap the damaged part with insulating tape to ensure that all exposed copper wires are covered and avoid direct contact with live parts.
• Loose wiring: Open the chair's shell (with the power off throughout the process) and tighten the wiring ports with a screwdriver to ensure a firm and loose-free connection.
• Damaged electrical components: Directly replace the damaged motors, control modules, or the entire chair. Do not disassemble and repair them privately to avoid leaving potential safety hazards.
• Static electricity problems: Dry the metal parts with a dry cloth or connect a wire from the chair's metal legs to the wall or the grounding terminal of a socket to eliminate static electricity accumulation. If the electric leakage persists, stop using the chair and conduct further inspections.
• External equipment failure: If the rusting of the low-voltage conversion box causes an electric leakage, replace the rusty parts and check whether the connecting wires are dry.

Step 4: Seek professional assistance and take preventive measures
If you cannot determine the cause of the electric leakage or the problem still exists after handling it, immediately contact professional maintenance personnel to avoid secondary dangers caused by private disassembly. During daily use, regularly inspect the wires and wiring ports of electric chairs and keep them dry and clean. For non-electric chairs, avoid using them in humid environments. You can regularly wipe the metal parts and ground them to reduce the risk of electric leakage.
