LEV testing and certification in St Helens

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

Glass begins as silica sand by the tonne, and the batch house is where it flies: mixing, conveying and charging the raw materials of a trade this town invented at scale. Respirable crystalline silica in batch and refractory work is COSHH's gravest customer, tested every 14 months.

Extraction we test

LEV testing and certification for St Helens businesses

Extraction across the town runs from batch house and materials handling dust systems through refractory and hot-repair extraction to the weld fume and workshop LEV of the estates.

Batch silica is controlled where powder moves: capture measured at mixers, transfers and charging points against real material flow, enclosure and transfer design judged as part of the control rather than around it, refractory cutting and demolition treated as the acute RCS events they are, and the fine fraction owning every verdict because it owns the disease. Our thorough examination tests each point against design and HSG258, reports a pass or fail per hood with readings, and treats a historic trade's oldest hazard with modern strictness.

COSHH FAQs

LEV testing and certification: common questions

Do you carry out LEV testing in St Helens?
Yes. We test LEV across St Helens and the wider Merseyside area, covering batch silica kept strict. Call us to arrange a visit.
How quickly can you visit St Helens?
A St Helens 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.
