LEV testing and certification in Merseyside

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

Merseyside's working air carries cargo dust off the terminals, silica out of the glass trade's batch houses, and weld fume from yards and workshops that never stopped making. COSHH answers all of it with engineering controls, local exhaust ventilation proven at the source every 14 months.

SEIS Engineering provides LEV thorough examination and testing across Merseyside, Liverpool, St Helens and Birkenhead included, every system tested against its design and reported hood by hood.

What we cover

LEV testing and certification across Merseyside

The county's hazards range from bulk-scale to bench-scale: terminal and intake dust at ship-discharge volumes, refractory and batch silica treated with the gravity it demands, fume captured in spaces confined enough to make extraction the whole plan, all under Regulation 9 with records kept five years.

Our P601 qualified engineers measure capture where each hazard is actually made, compare it to design and HSG258 benchmarks, and report a pass or fail per hood with readings attached.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing across Merseyside?
Yes. We test LEV across the whole area, Liverpool, St Helens, Birkenhead and the sites between, covering terminal, batch and yard systems alike. Call us to arrange a visit.
Can you arrange LEV testing across Merseyside quickly?
A 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.
