Precautions for high-altitude operations:

1. Use safety belts: When carrying out high-altitude operations, be sure to use safety belts and ensure that they are fixed on stable supports.

2. Check the work environment: Before starting the work, check the surrounding environment to ensure that there are no hazardous factors, such as wires, sharp objects, etc.

3. Pay attention to wind power and stability: When working at heights in strong or unstable environments, special attention should be paid to windproof measures and appropriate safety protection measures should be taken.

4. Do not work alone: When working at heights, try to work with colleagues as much as possible to help each other and provide support when needed.

5. Stay focused: When working at heights, stay focused and avoid distractions, especially when performing dangerous operations.

6. Regular safety training: High altitude workers should participate in safety training regularly to update their knowledge and improve their safety awareness.
