Sculpture I / Health, Safety and Sustainability in the Workshop
Practice question · Put in order

Arrange the controls for airborne dust from the most to the least reliable.

Hints
  1. The most reliable control removes the hazard rather than the exposure.
  2. Personal protection depends on fit and discipline, so it ranks low.
Show the answer
  1. Eliminate the dusty process or substitute a wet one
  2. Capture the dust at the point it is generated
  3. Ventilate the general workspace
  4. Wear fitted respiratory protection
  5. Rely on cleaning up afterwards
Why

The ordering is the standard hierarchy of control and its logic is that reliability falls as the control depends more on individual behaviour. A wet process protects everyone in the room whether or not they are thinking about it; a respirator protects one person, if it fits, if it is worn, and if it is maintained.
