What does Fall Restraint mean ?

What does “Fall Restraint” mean ?   Is it an “oxymoron” ?

Fall restraint






Restraint, means that the worker cannot get into a position from which they can fall. They are Prevented from falling. They are operating within the third level of the Work at Height hierarchy, Personal Fall Prevention.
Fall .. means they can fall. They accelerate under force of gravity  .. things then normally go badly …… they are much further down the hierarchy.
I frequently see this “odd term” used in specification and RAMS … what is it trying to say  .. fall prevention, or not ?
May I, please, start a campaign to use the term Restraint for Personal Fall Prevention .. at least we then know what we are trying to achieve.
