How to Ensure the Safety of Home Elevators During Maintenance

Periodic maintenance is crucial for the reliable operation and longevity of home elevators. However, ensuring safety during the maintenance process is equally important to prevent accidents and protect both personnel and equipment. Below are key guidelines to maintain safety during home elevator maintenance:

1. Adhere to Electrician Safety Regulations

Maintenance personnel must strictly follow safety protocols for electricians. Before inspecting or working on circuits, ensure capacitors are fully discharged to avoid electric shock.

2. Avoid Electric Shock in Wet Conditions

• When working in damp environments, take precautions to prevent electric shocks.
• If the elevator's bottom pit is waterlogged, cut off all power supplies before draining and performing maintenance tasks.

3. Disconnect Power Before Maintenance

• Before starting any electrical work, disconnect both the main and control power supplies.
• Remove fuses and clearly display a warning sign stating: “Someone is working; power transmission is prohibited.”

4. Use Proper Wiring and Installation Practices

• Select appropriate types and models for distribution lines based on the equipment's requirements.
• Ensure conductor cross-sections are suitable, and avoid using bare wires.
• Securely and neatly lay lines to prevent contact with moving parts, such as steel bars, scaffolding, guide rails, or other conductive surfaces.

5. Ground Power Lines Safely

• Power lines operating at 110V with a current of 15–20A must be properly grounded.
• Temporary lighting lines are an exception; however, avoid connecting external sockets to lighting circuits unless they are grounded.

6. Avoid Unsafe Practices with Electricity

• Do not use iron or scaffold steel pipes as grounding wires for welding circuits.
• Refrain from using the elevator's accompanying cable for high-current tasks like electric welding.

7. Use Insulated Tools

• Always use tools with appropriate insulation to avoid accidental contact with live circuits.

8. Verify Equipment Readiness

• Thoroughly inspect all electrical control and starting devices before working on halted equipment.
• For equipment with remote control functionality, remove the remote control fuse, lock the power supply, and clearly identify disconnection points or switches.

9. Handle Electric Shock Accidents Calmly

• If an electric shock occurs, immediately cut off the power supply.
• Avoid direct contact with the affected person. Instead, use non-conductive materials to separate them from the source or disconnect the power.

Final Thoughts

By following these safety practices, the risk of accidents during home elevator maintenance can be significantly reduced. Prioritizing safety not only protects maintenance personnel but also ensures the elevator remains functional and secure for daily use.
