What do the Work at Height Regulations govern?

The Work at Height Regulations specifically focus on ensuring the safety of individuals who are working in elevated positions, where there is a risk of falling that could lead to injury. These regulations outline the responsibilities of employers to assess risks, provide appropriate safety measures, and ensure proper training for workers who may be required to operate at heights.

This includes the use of equipment such as scaffolds, ladders, and harnesses, ensuring that work is properly planned, and that employees are trained to recognize hazards associated with working from elevated areas. Thus, the emphasis on safety measures while working at elevated places aligns perfectly with the core purpose of the Work at Height Regulations, making it the correct answer.

In contrast, the other options pertain to different aspects of workplace safety, such as underground work, machinery operation, and lifting operations, which are governed by different regulations and do not specifically address the risks associated with height-related work.
