Which option is NOT one of the five components of a Local Exhaust Ventilation System?

Explanation:
Local exhaust ventilation is designed to capture contaminants at the source and move them away from the worker’s breathing zone. The essential parts are the capture hood to grab the contaminants, the ductwork that carries the air, the fan that creates the flow, and the exhaust path that vents air to the outside. A filter is not a required component of the basic LEV system; filtration may be added in some specialized setups, but the core LEV configuration typically does not include a filter. Therefore, the item that isn’t one of the five core components is the filter.
