LEV Testing · Coventry
From the advanced-manufacturing and 3D-printing works about Ansty Park to the engineering, print and joinery units across the city, Coventry workplaces raise fume, mist and dust that the law says must be controlled - and the control proven by a thorough examination and test.
Coventry built Britain's cars and it still leads its advanced manufacturing. Its industry runs out to Ansty Park, Foleshill and Whitley, where 3D-printing and additive-manufacturing units sit alongside the engineering, automotive and food works that serve the West Midlands. Every one of them raises something a worker should not breathe - metal and polymer powder, weld and laser fume, oil mist, solvent or wood dust.
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 3D-printing and additive-manufacturing workshop about Ansty Park, the extraction over the powder-bed machines and the finishing bench had dropped off, fine metal powder and fume reaching the floor. We measured capture at each machine and hood, checked the ducting and filtration, and found a fan below duty and a blocked take-off - a real risk with reactive metal powder. We set out the remedial action, and re-tested to confirm the control before certifying.
At an engineering works in Coventry, the mist extraction over the CNC line and the weld-fume arms 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.
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 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 Ansty Park and Foleshill units and the city's units, and across Coventry and the wider the 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.
Coventry put the country on wheels - cycles, then cars, then aero engines - and that making instinct has carried into the advanced-manufacturing and additive works about Ansty Park today. Every one of them handles material a worker should not breathe, and carries a duty to control the powder, fume and mist 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.
