When climbing without a safety rope (i.e., free climbing or bouldering), several steps need to be taken to minimize risk. Even so, free climbing can still be dangerous and should be approached with caution. Here are some tips to reduce risk: 1. **Choose the right route**: Choose routes that are moderately difficult and that you are familiar with. Avoid cliffs and overly complex routes. 2. **Ensure good weather conditions**: Avoid climbing in rainy, windy, or unstable weather conditions, which increase the risk of slipping and falling. 3. **Use high-quality climbing shoes**: Proper climbing shoes can provide better grip and stability, reducing the possibility of slipping. 4. **Carry a chalk bag**: Climbing chalk can help keep your hands dry and increase friction, thereby improving your grip. 5. **Physically prepare and warm up properly**: Ensure you are in good physical condition, including physical fitness and muscle strength training, and warm up thoroughly before climbing to prevent injuries. 6. **Master techniques and skills**: Continuously improve your climbing skills and learn and practice various grips, moves, and methods of getting out of trouble. 7. **Use crash pads**: When bouldering, use crash pads to protect yourself from the bottom to reduce potential fall injuries. 8. **Ensure peer supervision**: Have experienced climbing partners accompany and guide you, who can provide help and advice at critical moments. 9. **Know and be familiar with escape routes**: Familiarize yourself with the surrounding terrain and possible escape routes before climbing, so that you can evacuate quickly in an emergency. 10. **Increase mental preparation**: Self-assess your mental state and risk tolerance to ensure that you remain calm and focused during the climb. Despite these measures, free climbing still involves high risks and is not suitable for inexperienced climbers. It is important to assess whether you are suitable for this activity based on your own abilities.
