LEV Testing · Wednesbury
From the hot-dip galvanizing plant to the tube and engineering units, Wednesbury workplaces raise fume, mist and dust that the law says must be controlled - and the control proven by a thorough examination and test.
Wednesbury's Black Country metal trade runs on around Bilport Lane and Potters Lane, and a hot-dip galvanizing plant among it pickles steel and dips it in a molten-zinc kettle. Where a plant pickles in acid and dips in molten zinc the fume and mist are real - the acid pickle throws off a mist and the zinc kettle a plume of zinc-oxide fume that brings on metal-fume fever - and the estates' tube, welding and grinding units add manganese fume and dust, all things a worker should not breathe.
Local exhaust ventilation is what captures it at source, and the law does not take the control on trust. Under COSHH the extraction has to be thoroughly examined and tested at least every 14 months, measured against how it is used - not just switched on and 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.
Real jobs, described by sector and area - never by a client's name.
At a hot-dip galvanizing plant on the Bilport Lane estate near Wednesbury, pickling steel and dipping it in the zinc kettle, the extraction over the pickle tanks and the kettle had lost capture and acid mist and zinc-oxide fume were rolling across the plant. We measured capture at the pickle-tank lips and the kettle hood, checked the ducting and the scrubber, and found a fan below duty dragging the run. We set out the remedial action, and re-tested to confirm the control before certifying.
At a tube and engineering unit on the Potters Lane estate near Wednesbury, the weld-fume arms and mist extraction over the machining had lost capture and the shop was hazing by mid-shift. We measured capture and face velocities at each point, checked the ducting and the filters, and reported what needed putting right so it held its spec on a re-test.
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.

A thorough examination and test under COSHH is a real assessment, not a rubber stamp. It is a structured examination of the system's condition, measurement of its actual performance, and an assessment of those readings against how the system should perform to control the exposure. It follows the HSE's guidance, HSG258, and ends in a report and a label.
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 examine the hoods, ducting, filter and fan and identify how each is meant to control its process.
We record capture and face velocities, transport velocity and static pressure at every key point.
The readings are assessed against the design intent under HSG258, with a clear verdict on control.
The plant is labelled with the result and next-due date, and you get the report for the COSHH file.
At least every 14 months under COSHH Regulation 9 - and sooner for certain higher-risk processes. We set the right interval for what you run and put the next-due date on the label and the report.
A thorough-examination-and-test report against HSG258, a pass/fail on each point with any remedials listed, and a dated label on the plant showing when the next test falls due.
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 the Bilport Lane and Potters Lane estates and the town's units, and across Wednesbury and the wider West Midlands.
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.

Wednesbury keeps a hot-dip galvanizing plant and the tube and engineering units of the Black Country around Bilport Lane and Potters Lane, pickling steel, dipping zinc, welding and machining - raising zinc-oxide fume, acid mist, weld fume and dust. Every one carries a duty to control what its work throws off - and to prove it with a measured test.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across West Midlands 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 West Midlands.
