What to do when you are trapped in a lift?

This post will be sharing with you guys what are the ways that you should do when you are trapped in a lift. So please read carefully as it might help. Anyway, thanks to terence for sharing this piece of information. :)

What to do?
FIRST: Quickly press all the different levels of buttons in the lift.
SECOND: Hold on tight to the handle (if there is any).
THIRD: Lean your back and head against the wall forming a straight line.
FOURTH: Bend your knees.

Why?
When the lift falls, you will not know when it will hit the ground, and it may result in whole body bone fracture.
POINT 1: When the emergency electricity supply is being activated, it will stop the lift from falling further.
POINT 2: It is to support your position and prevent you from falling or getting hurt when you lost your balance.
POINT 3: Leaning against the wall is to use it as a support for your back/spine as protection.
POINT 4: Ligament is a flexible, connective tissue. It can be attached to the bone part of the activities, but limit the scope of their activities in order to avoid injury.
