Local Exhaust Ventilation 3
Local Exhaust Ventilation 3 : Local exhaust ventilation is the removal of contaminated air directly at its source. This type of ventilation can help reduce worker exposure to airborne materials more effectively than general ventilation. This is because it does not allow the material to enter the work environment. It is usually recommended for hazardous airborne materials. See also: Mechanical Ventilation and Ventilation
