'Engineering controls' focus on the physical design or modification of the workplace to eliminate or reduce hazards. This can include implementing safety features in machinery, improving ventilation systems, or using barriers to separate workers from harmful substances or noise. The core objective of engineering controls is to create a safer environment by directly addressing the sources of risk, thus preventing hazards from affecting workers.
In contrast, modifying worker behavior involves training and encouraging safe practices, which does not eliminate the hazard itself. Providing detailed instructions may enhance awareness but does not physically change the environment. Ensuring compliance with regulations is essential for maintaining safety standards, but it does not address the root cause of hazards. Therefore, the primary aim of engineering controls is to effectively remove hazards from the environment, making it the most appropriate choice.
