While these could be freak it is equally important not to 'abuse' the escalator and elevator. Use them as their intended use and never over load them. When the lift is stuck, wait for the rescue team to secure the lift before getting out and don't try to force open the door yourself.
I have witnessed many people complaining everytime they are trapped in a lift. They just want to get out fast but forget the safety aspect. What is the point of getting out but not safe?
Steinau frantically pushed every button; the elevator stopped four feet below the fifth floor. She was trapped inside the elevator with his head for more than an hour. "I just keep seeing the look in his eyes," she told officers.
Not as dramatic as what happened with previously mentioned incidents in particular that involving the case of the female nurse in a hospital where she got sliced and decapitated instantly  but more of an agonising, slow death which is a worse way to go IMHO.
