25,000 pounds manufactured or processed, or 10,000 pounds otherwise used

Question 4

Which type of industrial ventilation system is best suited for controlling airborne contaminants generated at a fixed point, such as a welding station?

Accepted Answer

Local exhaust ventilation (LEV)

Answer

Local exhaust ventilation captures contaminants at their source before they disperse into the work environment, making it more effective and efficient than dilution ventilation for fixed-point sources.
