LEV testing and certification in Sheffield

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

Sheffield's steel, metalworking and advanced manufacturing sites rely on extraction over grinding, cutting and machining. COSHH requires that local exhaust ventilation to be thoroughly examined and tested at least every 14 months, and more often where the dust is especially harmful.

Extraction we test

LEV testing and certification for Sheffield businesses

Some dusts carry low workplace exposure limits, such as respirable crystalline silica from cutting and grinding stone or metal, which means the extraction has to keep airborne levels very low indeed. The examination measures capture velocity at the hood, airflow and duct velocities, and filter and fan condition against the design and HSG258 to confirm it does.

On-tool and downdraught extraction count as LEV too and are tested the same way, focused on whether the contaminant is captured at source. The same discipline covers welding fume, abrasive and fine dust, mist and vapour.

How it works

Booking your LEV test in Sheffield

We trace the system from the process back to the discharge, measuring at each point so the verdict rests on data. The report records a pass or fail per hood, photographs, recommended remedial works and the next due date.

COSHH FAQs

LEV testing and certification: common questions

Can you carry out LEV testing in Sheffield?
Yes, our P601 engineers cover Sheffield and the surrounding Yorkshire towns, from a single grinding extract to a full system. Call 0330 043 8191 and we will arrange a visit around your production.
How quickly can you visit Sheffield?
We have surveyors across Yorkshire, so a Sheffield visit is usually only a few working days away, sooner for an urgent re-test. Call 0330 043 8191 to arrange around 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.
