LEV testing and certification in Stockton-on-Tees

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

Parts cleaning is chemistry in an open tank: solvents and degreasers doing their work and evaporating toward whoever leans over them. In Stockton's maintenance workshops, the extraction on tanks and benches is a COSHH control like any other, and Regulation 9 tests it every 14 months.

Extraction we test

LEV testing and certification for Stockton-on-Tees businesses

Extraction across the town's workshops and plants runs from solvent tank and degreasing extraction through welding and grinding fume capture to dust systems and the process ventilation of the manufacturing estates.

Vapour control is judged where the vapour rises: capture measured at the tank lip and across the working opening, lids and covers factored as found rather than as intended, and the system proven against the solvents actually in use, because a hood designed for one vapour density can underperform on another. We test solvent and degreasing extraction on those terms, alongside every other hood on site, and report a pass or fail per unit with readings, remedial actions and the next date.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing in Stockton-on-Tees?
Yes. We test LEV across Stockton-on-Tees and the wider Teesside area, covering solvent, fume and dust extraction. Call us to arrange a visit.
How quickly can you visit Stockton-on-Tees?
A Stockton-on-Tees 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.
