What is an example of a lower order control measure?

A lower order control measure refers to strategies that are less effective at eliminating risks compared to higher-order controls. In the context of scaffolding, the primary objective is to eliminate hazards or minimize risk as much as possible.

Choosing scaffold catch platform safety nets as an example of a lower order control measure is appropriate because they are designed to catch falling objects and prevent injuries. However, they do not eliminate the hazard of objects falling altogether or the risks associated with working at heights. They serve as a safety precaution that relies on reactive measures rather than proactive, preventative actions.

In contrast, other options like scaffold safety railings are more effective at preventing falls, and training programs are essential for educating workers about hazards and safe practices, both of which contribute to reducing risks more fundamentally, making them higher order controls. Similarly, personal protective equipment (PPE) serves as an additional layer of safety but also does not eliminate risks in the working environment. Hence, while all these measures have their place, the catch platform safety net distinctly illustrates the nature of a lower order control by not addressing the root causes of the risks involved in scaffolding.
