Ventilation/ Local Exhaust Ventilation (LEV)
Ensuring Effective Capture of Airborne Contaminants
Local Exhaust Ventilation (LEV) systems are only effective when correctly designed, maintained, and verified. Poor performance can result in continued worker exposure to hazardous airborne contaminants.
​
We assess ventilation systems to ensure they are operating effectively and controlling exposure at the source.
Our Ventilation Services
LEV testing
We provide LEV testing and performance verification to ensure your extraction systems are operating effectively and protecting workers from airborne contaminants. Depending on the system and application, a range of tests may be carried out to assess overall ventilation performance and compliance.
LEV Hood Assessment and Design
Extraction hoods need to work with the process. A hood design that is mispatched to the process or task can be just as ineffective as low airflow rates. We assess and work with your people to find the most effective and efficient hood design.Â
Face velocity measurements
Measuring airflow velocity at hoods and extraction points to verify system performance.
Duct airflow verification
Confirming airflow rates throughout the duct system meet design and operational requirements.
Capture Efficiency and Velocity Assessment
Assessing how effectively airborne contaminants are captured in the working zone before entering the workplace.
Smoke visualisation testing
Visual airflow testing to identify capture performance, dead zones, and airflow patterns.
Why This Matters
Ventilation is a critical engineering control, but performance can degrade over time. Regular verification ensures continued protection and compliance.
