Penarth · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Penarth workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Penarth
Penarth is the Vale of Glamorgan's elegant seaside town, an affluent Cardiff commuter town of around 22,000 people on the headland where the Ely and Taff meet the Bristol Channel. In Victorian days it was promoted nationally as the Garden by the Sea, drawing day trippers from the valleys and holidaymakers from the Midlands and the West Country, and its cast-iron pier of 1898 with its restored art-deco pavilion still crowns the Esplanade.
Behind the seafront and the marina, its working trade sits in the units strung along Penarth Road towards Cogan and Llandough, in the Llandough Trading Estate and West Point Industrial Estate that serve the town and the wider Cardiff Bay fringe.
Every one of those Penarth processes puts fume, dust, mist or vapour into the air, and COSHH requires it controlled at source - which means local exhaust ventilation, thoroughly examined and tested at least every fourteen months. We test the LEV across all of it - from the Llandough Trading Estate units to the smaller Penarth workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
A system that catches fume, dust, mist or vapour at the point it is released is LEV, and for Penarth employers and others across Vale of Glamorgan it is the record COSHH looks for first.
Oil-mist and coolant-mist extraction on CNC machining centres and turning shops in the Llandough Trading Estate and West Point Industrial Estate units off Penarth Road, where fine metalworking mist has to be captured at the machine.
Steam canopies, flour-dust control and cold-store ventilation in the food producers and bakeries around the Penarth Road estates, including established occupiers on the Llandough Trading Estate that pack and prepare food for the Cardiff and Vale market.
Fine-dust extraction and downdraught tables at Penarth cabinet shops and joinery works, where hardwood and MDF dust is drawn off at the tool before it reaches the lungs.
On-torch extraction, fume arms and downdraught benches across the Cogan and Penarth Road workshops, from roofing and metalwork firms to general fabricators. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at the accident-repair and bodyshop units on the Penarth Road estates. Two-pack paints release isocyanates - the leading cause of occupational asthma - so booth airflow is examined to its design figure.
Fume-cupboard face-velocity testing for the laboratories and teaching facilities at University Hospital Llandough on the town edge, to the containment their work demands.
On the ground in Penarth
We are out under Penarth's extraction every week. The proof that matters is the jobs, not a stock photo.
The extraction on the fabrication bench at a Penarth shop wasn't pulling as it should, which came down to a slipping fan drive belt. We took benchmark readings, visualised capture at each hood and cleared the debris in the ducting. One point failed on a tired filter to begin with and passed after remedial work, with the benchmark readings logged and reported. We left the workshop manager a short photo report for their maintenance log.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Penarth system it answers three things: is the system intact, does it still capture, and does that capture match what it was designed to do.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Llandough Trading Estate units - the faults that quietly kill capture.
Face and capture velocities, static pressures and airflows measured at each hood with calibrated instruments - numbers, not opinion.
Readings compared to the system's commissioning figures, so drift from as-designed is caught before it becomes a failure on a Penarth line.
Where exposure is in question - a precision engineering and manufacturing process, say - sampling confirms whether control is actually protecting the people at the process.
The duty
COSHH Regulation 9 makes it plain: any LEV controlling exposure to a hazardous substance has to be thoroughly examined and tested at intervals no greater than fourteen months, and the resulting records kept for at least five years.
For the great majority of Penarth sites, from the Llandough Trading Estate units to the one-man workshops, the fourteen-month deadline is what catches people out: once it passes the system is non-compliant regardless of its actual state. We carry out the examination, label every hood with its status and next-due date, and issue the report an HSE inspector or your insurer expects to see - and if a point fails, you get the number, the cause and the fix rather than a bare fail.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Penarth site.
Calibrated velocity, pressure and airflow readings at each extraction point.
A COSHH-compliant report: results against benchmark, clear pass or fail, and plain-English actions for the Penarth duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the West Point Industrial Estate floor.
Questions
Under COSHH Regulation 9, most local exhaust ventilation needs a thorough examination and test at least every 14 months, with higher-risk processes more often. A precision engineering and manufacturing bay, a food and drink production bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
A dated report to the HSG258 method, the readings taken, a pass or remedial outcome for each hood, and system labelling - the evidence a duty-holder at Llandough Trading Estate or a smaller Penarth workshop needs for their COSHH file.
precision engineering and manufacturing, food and drink production, woodworking and joinery, welding and fabrication, vehicle body and paint, and laboratory fume cupboards - the trades clustered around Llandough Trading Estate and West Point Industrial Estate and across the wider Vale of Glamorgan.
We record it as remedial and set out what is needed - airflow, ductwork, filtration or capture at the hood. You do the work and we re-test, and on a Llandough Trading Estate production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
Yes - the industrial estates and workshops around Llandough Trading Estate and West Point Industrial Estate, the university and hospital labs, and the wider Vale of Glamorgan.
No. LEV testing is a statutory examination of fume and dust control to COSHH and HSG258, with capture and face-velocity readings; TR19 is kitchen grease and fire risk. We do both across Penarth, but a Llandough Trading Estate fabrication shop and a Glebe Street canopy are kept as the separate jobs they are.
Yes. A new spray booth or fume-arm install at a Penarth workshop needs a commissioning test to prove it performs to its design figures before it goes into service - we measure it and document the baseline the 14-month clock then runs from.
Local knowledge
Penarth Dock opened in 1865, built by the Windsor and Plymouth estates as a rival to Cardiff for the export of Welsh steam coal, and by 1876 it worked eleven hydraulic coal tippers alongside its ballast cranes. That heavy-engineering instinct still runs through the machine shops and fabricators strung along Penarth Road towards Cogan, and every one of them carries a duty to control the mist, fume and dust its work throws off. We test and certify local exhaust ventilation to the standard COSHH sets, so the extraction reads true against its design figures.
