The correct answer is based on the definition of engineering interventions in the context of health and safety programs. Engineering interventions typically involve changes to the physical aspects of the workplace—such as processes, equipment, or the environment—designed to minimize risks and improve safety.

Modifying work processes and equipment directly addresses potential hazards by altering the way work is performed or by implementing safer machinery or tools. This proactive approach can substantially reduce the likelihood of accidents and injuries by creating safer conditions in which employees operate.

In contrast, modifying workplace procedures and policies, encouraging worker involvement, and following safety-related rules tend to focus more on behavioral and administrative controls rather than making hazardous environments inherently safer through physical changes. While these strategies are important in a comprehensive health and safety program, they do not fall under the category of engineering interventions, which are specifically centered on tangible modifications to equipment or processes.
