LEV testing and certification in Lincolnshire

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

Workshops, factories and process sites across Lincolnshire rely on local exhaust ventilation to keep dust, fume and vapour out of the air. COSHH makes that extraction the employer's responsibility, with a thorough examination and test required at least every 14 months.

What we cover

LEV testing and certification across Lincolnshire

What counts as LEV is broader than many people expect: any engineered system that draws a contaminant away from the breathing zone, from fixed ducted plant to on-tool and portable extractors. We test all of it the same way, measuring capture velocity at the hood, airflow and duct velocities, and filter and fan condition against the design figures and HSG258.

That covers welding and soldering fume, wood and fine dust, fume cupboards and cabinets, solvent vapour and oil mist. Whatever the process, the question the test answers is the same: is the contaminant captured at source so exposure stays adequately controlled.

COSHH FAQs

LEV testing and certification: common questions

Do you cover the whole of Lincolnshire?
Yes, our P601 engineer surveyors work right across Lincolnshire, from a single extraction unit to large multi-hood systems, and you can choose your nearest town below. Call 0330 043 8191 to arrange a thorough examination and test.
How quickly can you arrange a visit in Lincolnshire?
We keep engineer surveyors working across Lincolnshire, so we can usually be on site within a few working days, and sooner for an urgent re-test on a failed system. Call 0330 043 8191 and we will book a time that fits your production.
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.
