An example of an ergonomic engineering control is:

Using adjustable-height chairs and tables is an example of an ergonomic engineering control because it directly addresses the design of the workplace and the tools used by employees. Ergonomic engineering controls are implemented to modify the physical environment or the equipment in a way that reduces physical stress and minimizes the risk of musculoskeletal disorders. Adjustable furniture allows employees to customize their workspace to fit their individual body dimensions and movements, promoting better posture and reducing strain associated with prolonged sitting or standing in non-ideal positions.

In contrast, the other options focus more on organizational practices or administrative controls rather than changes to the physical environment. For example, cross-training can help distribute workloads but does not necessarily improve ergonomics. Monitoring lifting procedures helps in ensuring safe practices but does not alter the environment itself. Providing rest breaks can reduce fatigue, but it does not fundamentally change how the workplace is structured ergonomically.
