LEV testing and certification in Teesside

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

Process industry, fabrication, chemicals and heavy manufacture make Teesside one of the hardest working airsheds in Britain, and inside its buildings COSHH puts the burden on engineering controls: local exhaust ventilation that provably captures what people would otherwise breathe.

SEIS Engineering provides LEV thorough examination and testing across Teesside, Middlesbrough, Stockton-on-Tees and Hartlepool included, every system tested against its design on the fixed 14 month cycle and reported hood by hood.

What we cover

LEV testing and certification across Teesside

Extraction across the area serves welding and cutting fume in the fabrication trades, dust and process emissions in manufacturing, spray and finishing work, and the bench and workshop systems of every estate. COSHH Regulation 9 puts each provided system on thorough examination and test at least every 14 months, with records kept five years.

Our P601 qualified engineers measure airflow and capture performance at every hood against the system's design and HSG258 benchmarks, report a pass or fail per hood with the readings behind it, and say plainly what needs fixing, so the certificate means what it appears to mean.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing across Teesside?
Yes. We test LEV across the whole area, Middlesbrough, Stockton-on-Tees, Hartlepool and the sites between, covering welding fume, dust and process extraction. Call us to arrange a visit.
Can you arrange LEV testing across Teesside 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.
