In this episode Adrian Sims, Managing Director at Vent-Tech Ltd joins host Mark Reggers for the first of a two-part series to discuss local exhaust ventilation. Local exhaust ventilation (LEV) is an engineering control designed to reduce or eliminate worker exposure to dust, fumes or other hazardous airborne substances that are created by numerous processes in the workplace. An LEV system captures the emissions at the source, removing them from the work area before inhalation to protect worker health.
