What is the role of local exhaust ventilation in the workplace?

To cool down machinery
To distribute air contaminants evenly
To capture and remove emissions before they reach the worker
To supply fresh air to confined spaces

The correct answer is: To capture and remove emissions before they reach the worker

Local exhaust ventilation plays a critical role in the workplace by capturing and removing any emissions before they reach the worker. This helps to prevent air contaminants from entering the worker's breathing zone and potentially causing health issues. Options A, B, and D are incorrect as they do not address the specific purpose of local exhaust ventilation in workplace safety. Cooling down machinery, distributing air contaminants, and supplying fresh air to confined spaces may be important in certain workplace environments, but they are not the primary role of local exhaust ventilation.
