What does engineering control refer to in a safety context?

Engineering control refers to modifications made to the physical environment in a workplace to minimize or eliminate exposure to hazards. This approach aims to design out the hazard rather than relying solely on worker behavior or administrative controls. For instance, implementing safety guards on machinery, improving ventilation systems to reduce airborne contaminants, or using noise barriers to protect workers from excessive sound levels are all examples of engineering controls.

This method is considered one of the most effective strategies in occupational safety because it directly addresses the source of the hazard, thus reducing the risk to workers without requiring behavioral changes. By making physical changes to the work environment, engineering controls can often provide a more permanent solution to safety issues, leading to a safer workplace overall.

The other choices, while they may play significant roles in an overall safety strategy, do not fit the definition of engineering controls. Adjustments to work schedules can help manage fatigue but are an administrative control. Training programs focus on educating employees about safety practices, which is also an administrative measure. Establishing safety policies involves setting procedures and guidelines, contributing to a culture of safety but does not physically alter the workplace environment.
