Which of the following is an example of an engineering control for worker protection?

Engineering controls are physical changes to the workplace that remove or reduce the hazard at the source. Isolation fits this because it creates a physical separation between the worker and the hazard, such as enclosing a hazardous process, installing guards, or placing the equipment in a restricted area. By keeping people out of the hazardous zone, exposure is reduced regardless of worker behavior. In a shop, this is like using a guard or enclosure to keep hands away from moving parts or isolating a hot operation behind a barrier. The other options don’t meet this engineering approach: administrative controls and training change how people work but don’t remove the hazard itself, and PPE protects the worker without reducing the hazard at the source.
