What is meant by engineering controls in a workplace setting?

In a workplace setting, engineering controls refer to modifications made to the physical environment or equipment to reduce exposure to hazards. This approach aims to eliminate or minimize risks by designing safer workspaces or using protective equipment. Examples include installing ventilation systems to remove airborne contaminants, using machine guards to prevent injuries, or redesigning workstations to improve ergonomics.

Adjusting job roles, employee schedules, or providing training on safety protocols may contribute to overall workplace safety, but they do not constitute engineering controls as they do not involve direct changes to the work environment itself. The focus of engineering controls is on altering the design of the workplace or the equipment used, making this response the best fit for the question.
