Ventilation Assessment Services in Australia
Ventilation assessment evaluates the design, installation, and performance of local exhaust ventilation (LEV) systems and general dilution ventilation. Testing includes face velocity measurements at hoods and enclosures, duct velocity traverses, static pressure profiling, and capture efficiency verification using smoke visualisation.
Effective LEV is a critical engineering control for reducing worker exposure to airborne contaminants at the source. Regular testing ensures systems continue to perform as designed after modifications, filter changes, or ductwork alterations.
OHConnect ventilation practitioners use calibrated anemometers, pitot tubes, and manometers, reporting results against design specifications and industry benchmarks from ACGIH Industrial Ventilation and HSE HSG258.
When You Need This Service
- →New LEV systems require commissioning verification before use
- →Annual or periodic LEV performance testing is due
- →Exposure monitoring results indicate inadequate engineering controls
- →Process changes alter the contaminant generation rate or location
- →Workers report odours, visible fume, or dust escape from enclosures
- →A regulator requires evidence of LEV testing and maintenance
