Local Exhaust Ventilation (LEV) Testing

Local Exhaust Ventilation (LEV) systems are a primary engineering control for capturing dust, fumes, and vapours at the source before they can enter the breathing zone or accumulate to dangerous concentrations. Regular LEV testing verifies that these systems continue to perform as designed. In Singapore, workplace safety legislation requires employers to ensure that engineering controls remain effective throughout their service life.

DASH Consult performs LEV thorough examinations and performance testing in accordance with recognised standards. Our assessments include visual inspection of ductwork, hoods, and fans; measurement of capture velocities and transport velocities; static pressure profiling; and airflow distribution checks across the entire system.

After testing, you receive a detailed report documenting system performance against design specifications, identifying any deficiencies, and recommending corrective actions. We also provide ongoing monitoring programmes so that degradation is caught early and your workers remain protected.
