Which of the following reflects a duty that is limited by what is 'practicable'?

The concept of a duty that is limited by what is 'practicable' is best captured by the term "Reasonably Practicable Duty." This refers to the obligation to take safety measures that are feasible and manageable in terms of cost, time, and resources, in relation to the level of risk involved.

The principle of "reasonably practicable" implies balancing the risk against the measures needed to eliminate or control that risk. It recognizes that while it is essential to provide a safe environment, the means to achieve this must not be overly burdensome or unrealistic. This standard allows for the consideration of practicality while ensuring that efforts to mitigate risks are made.

In the context of occupational health and safety, understanding what is considered 'reasonably practicable' helps organizations determine their responsibilities effectively without imposing unnecessary or onerous obligations that cannot be fulfilled in a real-world context. This approach is not about achieving perfection in safety measures, but about being responsible and reasonable in managing workplace risks.
