What Does LEV Testing Include?
A thorough examination and test assesses the extraction system against its intended performance and the process it serves. We inspect the equipment and its use, take appropriate measurements and explain defects or limitations.
Inspection of hoods, ductwork, filters, fans and visible damage.
Airflow and pressure measurements appropriate to the system.
Assessment of contaminant capture during normal work, where safe and practical.
Review of available commissioning data, previous reports and maintenance records.
Your written report records the system assessed, test findings, identified defects and recommended actions. We explain any restrictions on what could be examined so you can plan the next steps.
Often called COSHH LEV testing, this examination checks performance; servicing maintains equipment and repairs address faults. A running fan alone does not demonstrate effective dust or fume control.
For specialist equipment, explore laboratory and cabinet testing and HEPA filter integrity testing. Where explosive-atmosphere hazards are relevant, we can also arrange ATEX inspections and DSEAR assessments through specialist engineers.
For controlled rooms, explore cleanroom and containment validation or healthcare ventilation verification. These services need a scope suited to the room, equipment and specification; they are not interchangeable with a general LEV examination.
Planning Your LEV Test
Share Your System Records
Send your previous examination report, commissioning information and details of recent repairs or process changes. These help establish what the system should achieve.
Show Normal Working Conditions
Arrange access to the equipment and, where safe and practical, demonstrate the process in normal use. How operators position and use extraction matters to its performance.
Allow Safe Access
Tell us about access restrictions, working hours and site safety requirements when booking. The number of systems and test points will affect the time needed.
Understand Your Report
Read the findings and ask about anything unclear. The report should explain the assessed performance, any defects and the actions needed to address them. Read our LEV report content guide.
Act on Defects
Address problems promptly and assess whether affected work can continue safely. We can discuss remedial work and any checks needed after repairs or alterations.
Plan the Next Examination
Most LEV systems need thorough examination and testing at least every 14 months; some require shorter intervals. Keep examination records for at least five years. Routine maintenance is also needed between tests.

A documented repair and retest
A laser-extraction examination identified ineffective control, leaking joints and inadequate supports. Premier LEV replaced ductwork and supports; a later examination recorded a satisfactory assessment within its scope and limitations. See the photographs and case study.
Before you book
Cost: system count, extraction points, complexity, access and location affect the quote. Use the quote checklist.
Production: we assess normal working conditions where safe and practical. Some checks need equipment stopped or isolated; agree timing in advance.
Missing records: send any drawings, information or photos you have. Missing data can limit comparison with intended performance.
Defects: use the report to assess risk and agree action. A repair alone does not prove satisfactory control; discuss the checks required afterwards.
