I don't think elevators are dangerous, but they need to be used safely. Elevators as special equipment, there are multiple safety protection devices, but no equipment can be 100% safe, need to be used correctly, regular maintenance and inspection, to minimize the risk. When taking the elevator, you should first check whether the elevator is normal, such as in the case of abnormalities in a timely manner to report processing, keep quiet, do not move, encounter failures or emergencies in a timely manner to seek help.
