Practice question · Multiple choice
Why is a hazard control that depends on individual behaviour considered less reliable than one built into the process?
Hints
- Compare a wet process with a respirator, in a shared room.
- One protects everyone present whether or not they are thinking about it.
Show the answer
A. It protects only the person applying it, only when applied correctly and consistently
Why
Because it protects one person, conditionally. A wet process suppresses dust for everyone in the room without anyone deciding to be careful; a respirator protects its wearer if it fits, if it is worn every time and if it is maintained. That is why the hierarchy of control puts personal protection near the bottom rather than because it does not work.
