LEV Testing · Magor
Across Magor, the engineering, joinery and vehicle workshops throw off fume, mist and dust the law requires to be controlled - and the control proven by a thorough examination and test.
Around Magor the brewing and engineering units weld, machine and fabricate, the joinery and timber shops cut and sand, and the vehicle and distribution workshops grind and refinish. Where a workshop welds and grinds the fume and dust are real - the arc and the grinder throw off weld fume and metal dust - and the joinery and refinishing units add wood dust, oil mist and paint mist, all things a worker should not breathe.
Local exhaust ventilation catches it at source, and the law will not take that on trust. COSHH requires the weld-fume arms, the wood-dust extraction and the spray and mist extraction to be thoroughly examined and tested at least every 14 months, measured in use rather than assumed to work.
CNC and manual machining raises oil mist and metal dust at the enclosure and bench that has to be captured at source.
Flour, powders and steam need capture at the mixing and process points, from bakeries to production kitchens.
Saws, sanders and routers throw fine wood dust that has to be drawn off at the tool and the bench.
Weld fume and grinding dust need capture at the arm and booth, wherever steel is fabricated.
Bodyshop spray booths and prep bays carry paint mist and solvent vapour that the extraction has to hold and clear.
Fume cupboards, safety cabinets and dental and salon extraction all count as LEV and all fall due on the same clock.
Typical jobs we handle, by sector and area - representative of the work we do, not named clients.
At an engineering unit near Magor, welding, grinding and fabricating, the extraction had lost capture and the shop was hazing by mid-shift. We checked capture at the hoods, the ducting and the filters, and found the fan and filters below the duty the process needed. We set out what to put right, re-tested after the work, and certified the system to HSG258.
At a distribution-depot workshop near Magor, spraying and finishing, the system was failing to catch the paint mist and solvent at source. We measured face velocities and static pressure, checked the run, and found undersized ducting and a worn fan. We listed the remedials, and re-tested to prove the control once put right, then certified to HSG258.
Condition of hoods, ducting, filters and fan - the damage, blockage and wear that quietly drops performance.
Measured capture and face velocities at the working points, plus transport velocity and static pressure through the system.
The readings assessed against how the LEV should perform to actually control the exposure - not just whether the fan turns.
Where the process warrants it, sampling to confirm the control is keeping the substance out of the breathing zone.
The point of a thorough examination and test is to prove the extraction still controls the exposure - so we measure it, we do not eyeball it. Condition, capture and face velocities, transport velocity and static pressure are checked against the design intent under HSG258, and the result is written up and labelled on the plant.
We test to the HSE's guidance, HSG258, and the job ends in a report and a label on the plant: what was measured, what passed, what needs putting right, and the date the next test falls due.
We inspect the system's condition - hoods, ducting, filter and fan - and identify how it is meant to control each process.
We take the readings: capture and face velocities, duct transport velocity and static pressure at the key points.
We assess the readings against the benchmark and set out clearly whether the system is controlling the exposure.
The system is labelled with the test result and next-due date, and you get the report for your COSHH file.
No more than every 14 months under COSHH Regulation 9, and sooner for certain higher-risk work. We judge the right interval for your process and put the next-due date on both the plant label and the report.
An HSG258 thorough-examination-and-test report, a clear pass or fail at every point with remedials listed, and a dated plant label carrying the next test date.
We set out exactly what failed and why - often a single reading such as static pressure or capture velocity - so it can be put right, and we re-test to confirm the control before certifying.
Yes - the Magor workshops and units, and across Magor and the wider Monmouthshire.
No - any LEV: welding fume arms, wood and grain dust systems, spray booths, mist extraction, fume cupboards, and dental and salon extraction all fall under the same duty and the same clock.
Around Magor the metal, timber and vehicle work raises weld fume, metal and wood dust, oil mist and paint mist. Every workshop that produces it carries the same duty: capture it at source, and prove with a measured test that the capture works.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across South Wales and the UK. From a machine shop to a joinery, a spray booth or a lab fume cupboard, the job ends the same way: measured readings, a clear verdict, and a label whose next-due date you can rely on.
Tell us what you run and we will examine, measure, report and label it to HSG258 - across South Wales.
