LEV thorough examination and testing in High Wycombe

Thorough examination, testing and certification of local exhaust ventilation by a P601 qualified engineer

Hardwood dust is a carcinogen, and High Wycombe's founding trade produces it by the sackful: the saws, moulders and sanders of the furniture and joinery shops make the dust, and the extraction over them is the legal control, due its thorough test every 14 months.

Extraction we test

LEV testing and certification for High Wycombe businesses

Wood dust extraction is tested where the dust is born: at each machine hood, with capture measured against the commissioning benchmarks that define what good looks like for that system. Sanding is the stress case, producing the finest and most dangerous fraction, and the hoods serving it get the closest attention.

System health shows in the measurements before it shows on the floor: filters loading, branch dampers crept out of balance, a new machine teed in without the airflow to serve it. The report catches the drift, ranks the fixes, and gives you the evidence trail wood-dust enforcement always asks for.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing in High Wycombe?
Yes. Our engineer surveyors cover High Wycombe and its furniture and joinery shops, testing dust extraction at the machines that make it. Call us to arrange a visit.
How quickly can you get to High Wycombe?
We keep availability across Buckinghamshire, so a High Wycombe visit is usually within a couple of working days, and we time testing around production so lines keep running. Call 0330 043 8191 to book your LEV test.
How often does LEV need to be tested?
Under COSHH Regulation 9 every local exhaust ventilation system must have a thorough examination and test at least every 14 months, and that interval is a legal maximum rather than a target. Higher-risk processes in COSHH Schedule 4 are tested far more often, in some cases monthly or six-monthly; the HSE sets this out in its guidance on LEV examination.
Is LEV testing a legal requirement?
Yes. The duty sits with the employer under COSHH Regulation 9, which requires extraction that controls a hazardous substance to be examined and tested by a competent person, and that responsibility stays with you even when the work is outsourced. You can read the duty in plain terms in our COSHH regulations guide.
What does an LEV thorough examination and test involve?
It is a structured check that the system still controls the contaminant the way it was designed to, not a service or a filter swap. We measure airflow and capture velocity at each hood, check duct velocities, filters and fan condition, and compare every reading against the design data and the HSG258 benchmarks.
Who is qualified to carry out LEV testing?
The HSE expects a competent person, which it links to BOHS-recognised training such as the P601 qualification. Our engineer surveyors hold P601 and report to the HSG258 standard, so the examination stands up to scrutiny.
What is in the LEV report, and how long must I keep it?
You receive the measured airflow and capture data, a pass or fail verdict at each test point, photographs, any remedial actions and the next due date, and it is this report an inspector asks to see rather than a service record. COSHH requires the records to be kept for at least five years, so we log every result against your system.
What happens if my LEV system fails the test?
The report sets out exactly why, for example low airflow, a worn fan or a badly positioned hood, and the remedial work needed to bring it back into adequate control. Once the work is done we can return to re-test and confirm the system is protecting people again.
