What is the purpose of an exhaust ventilation system?

The primary purpose of an exhaust ventilation system is to remove contaminated air from a space. This system is designed to capture and extract pollutants, hazardous fumes, vapors, and airborne particles from the work environment to ensure that the indoor air quality remains safe for workers. By effectively removing harmful substances, exhaust ventilation helps reduce the risk of respiratory illnesses and other health hazards associated with exposure to airborne contaminants.

This function is crucial in environments such as construction sites, manufacturing plants, or laboratories where airborne pollutants can significantly compromise worker safety. Implementing an effective exhaust ventilation system is a key part of maintaining compliance with OSHA standards and fostering a healthy workplace. The other options focus on different aspects of air management but do not specifically address the primary function of exhaust systems, which is the removal of contaminated air.
