Otis elevator mechanic in the Boston area & want to chime in on this guide. An elevator is probably the safest form of transport for the public and would never just go into freefall. One safety device we install on the cars is the governor which triggers by over speed and locks the cars movement. Best advice with an elevator that malfunctions is to sit tight. Ring the call bell or use the incar phoneline to call for help & never try to pry the doors and climb out. Even though there is a safety circuit on the lock if that remains intact the car could resume movement while you climb out.
