LEV testing and certification in Yorkshire

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

From heavy industry to food, engineering and laboratories, sites across Yorkshire use local exhaust ventilation to control the contaminants their processes give off. COSHH requires it to be thoroughly examined and tested at least every 14 months by a competent person.

What we cover

LEV testing and certification across Yorkshire

Local exhaust ventilation only protects people if it captures the contaminant where it is released, so the hood is where the examination really counts. We measure capture velocity at each hood and airflow through the system, then compare what the kit achieves against its design figures and the benchmarks in HSG258.

Moving air is not the same as controlling exposure, and a tidy-looking installation proves nothing on its own. The test is judged on whether welding fume, dust, mist or vapour is genuinely drawn away from the breathing zone.

COSHH FAQs

LEV testing and certification: common questions

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.
