Treadmill is a very common fitness equipment, which can help us do aerobic exercise, consume energy and lose weight. However, it will be very dangerous if children accidentally get their hands stuck on the treadmill. The following are the emergency measures that children should take:

1. Turn off the power of the treadmill immediately. This is the most important measure. Once the child's hand gets stuck on the treadmill, turn off the power as soon as possible to avoid causing more harm.

2. Gently remove the child's fingers from the machine with tweezers or similar tools. However, before the rescue, please make sure that the child's fingers are not severely twisted or broken.

If the whole palm is stuck instead of fingers, you need to seek the help of a doctor. The doctor will take the correct treatment according to the specific situation to avoid causing more harm.

To sum up, it is very dangerous for children to get stuck on the treadmill, and correct emergency measures need to be taken. If the child is seriously injured, he must be sent to the hospital for treatment in time. So be sure to be safe. When children play the treadmill, it is best to be accompanied by adults.
