LEV testing and certification in Derby

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

Derby's manufacturing and engineering base, from aerospace and rail to general workshops, runs extraction across a wide range of processes. A thorough examination and test is how COSHH confirms that extraction is still controlling exposure, and it is due at least every 14 months.

Extraction we test

LEV testing and certification for Derby businesses

COSHH expects exposure to be controlled at source, with extraction sitting high in the control hierarchy above masks and respirators. The examination tests whether the system delivers that control in practice, by measuring capture velocity at the hood, airflow and duct velocities, and the state of filters and fans against the design and HSG258.

Those principles do not change with the contaminant, whether it is welding fume, fine machining or grinding dust, solvent vapour or paint mist. Where enclosure or a booth is used, the test also looks at how well the design contains the process rather than relying on airflow alone.

How it works

Booking your LEV test in Derby

On site we record what the system should achieve, measure what it delivers now, and explain any shortfall clearly. You receive a report with a pass or fail at each test point, photographs, recommended remedial works and the date the next examination is due.

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.
