Local Exhaust Ventilation (LEV) is an engineering control system designed to capture airborne contaminants at source and prevent harmful exposure in the workplace.
LEV systems are commonly used to control exposure from:
A Thorough Examination & Test (TExT) is a detailed inspection and performance assessment of an LEV system to ensure it continues to effectively control airborne contaminants as originally designed.
Routine LEV testing helps identify:
Commissioning establishes the initial performance standards of a newly installed LEV system and confirms compliance with design and regulatory requirements, against an exposure benchmark.
Where commissioning data is unavailable or incomplete, retrospective commissioning establishes benchmark performance standards for ongoing statutory testing and maintenance.
Routine LEV testing verifies that the system continues to perform as intended and adequately controls employee exposure to hazardous substances.
Review of existing LEV documentation such as COSHH risk assessment and user manuals.
Inspection of hoods, ductwork, filters, fans and operator interaction.
Assessment of airflow performance and control effectiveness.
Detailed technical report including findings, professional judgement and recommendations.
