What is the purpose of Engineering Controls in a dental office?

1. To isolate equipment and materials to prevent exposure

2. To ensure the cleanliness of all surfaces

3. To provide personal protective equipment for staff

4. To improve the aesthetic appeal of the workspace

The correct answer is: To isolate equipment and materials to prevent exposure

Engineering controls are designed to minimize or eliminate exposure to hazards in a dental office setting. In this context, isolating equipment and materials effectively reduces the likelihood that aerosolized particles, dental debris, or chemicals will come into contact with dental staff or patients. This can include physical barriers, such as protective shields or isolation rooms, which help control the environment and prevent direct exposure to potentially harmful substances. Other options, such as ensuring cleanliness of surfaces, providing personal protective equipment, or improving the aesthetic appeal of the workspace, play important roles in maintaining a safe and welcoming environment, but they do not specifically address the engineering controls that directly modify the workplace layout or use physical barriers to minimize risk. Therefore, the primary purpose of engineering controls is to create a safer work environment by isolating dangers from staff and patients.
