LEV testing and certification in Chester

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

Chester's stones are old, but the dust off them is timeless: conservation and restoration cutting releases the same respirable crystalline silica as any quarry, in banker shops and on scaffolds beside heritage walls. COSHH tests the extraction over that work every 14 months, craft or no craft.

Extraction we test

LEV testing and certification for Chester businesses

Extraction across the city runs from masonry and conservation dust systems, banker shop extraction and on-tool capture, through workshop fume to the LEV of the trades.

Conservation silica is controlled in craft-shaped ways: capture measured at the banker where hand and pneumatic tooling actually works, on-tool extraction proven for the site tasks a fixed hood cannot follow, wet methods and extraction judged as the combined control heritage detail often requires, and the fine fraction owning every verdict because tradition impresses stone, not lungs. Our thorough examination tests each arrangement against design and HSG258, and reports a pass or fail per hood with readings attached and the cycle set.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing in Chester?
Yes. We test LEV across Chester and the wider Cheshire area, covering heritage stone, modern strictness. Call us to arrange a visit.
How quickly can you visit Chester?
A Chester 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.
