QUESTION 1
Read about the hierarchy of safety management controls and answer the
following question:
Define what is meant by safety management controls. (2)
Safety management controls are strategies, methods, or systems put in place to
protect workers by either eliminating or minimising exposure to hazards in the
workplace. They are arranged in a hierarchy known as the Hierarchy of Controls,
which ranks control measures from the most effective to the least effective. The
purpose of these controls is to systematically address risks, starting with removing
the hazard entirely, and only relying on measures like personal protective
equipment (PPE) as a last resort.
List and explain the five levels of the hierarchy of controls, starting with the most
effective. (5)
Elimination (Most Effective)
This involves physically removing the hazard so that it no longer exists in the
workplace.
If the hazard is gone, there is no longer any risk of harm to workers.
Example: Completely removing dangerous chemicals from a process instead
of storing them on site.
Substitution
This means replacing a hazardous material, tool, or process with a safer
alternative.
It reduces the risk because the new substitute is less harmful.
