Maesteg · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Maesteg workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Maesteg
Maesteg, whose name means the fair field, sits at the head of the Llynfi Valley in Bridgend county borough, a town forged out of coal and iron in the nineteenth century. It carries a claim few places can match, for the Welsh national anthem Hen Wlad Fy Nhadau was first sung in public here in 1856, in the vestry of Tabor Chapel. The Grade II listed Town Hall on Talbot Street, with its covered market beneath, still marks the centre of the old parish.
The valley's working economy grew out of the Llynfi Ironworks and the collieries at Coegnant, Caerau and St John's, and today its engineering and fabrication trades run from the trade units at Ewenny Road in Maesteg to the larger Village Farm Industrial Estate down towards Pyle and Bridgend.
Each of those Maesteg processes throws fume, dust, mist or vapour into the workplace air, and COSHH demands it is captured at source - that capture system is local exhaust ventilation, and it must be thoroughly examined and tested at least every fourteen months. We cover the lot, from the Ewenny Road Industrial Estate units to the one-bench Maesteg workshops, taking capture and face-velocity readings and leaving a clear pass or remedial verdict with the hoods labelled.
By sector
If a process captures fume, dust, mist or vapour at source, that capture system is LEV - and across Maesteg and the wider Bridgend it is your evidence under COSHH.
Oil-mist and coolant-mist extraction on CNC machining centres and turning shops, a direct inheritance of the iron and engineering trades the Llynfi Valley was built on, now grouped in the units at Ewenny Road and Village Farm.
Steam canopies, flour-dust control and hygienic extraction in the bakeries, butchers and food producers supplying Maesteg's shops and the wider Bridgend trade.
Fine-dust extraction and downdraught tables at valley cabinet shops and joinery works, where hardwood and MDF dust is captured at the tool before it reaches the lungs.
On-torch extraction, fume arms and downdraught benches across the Ewenny Road and Village Farm units, a trade with deep roots in the valley ironworks. Since the HSE reclassified welding fume in 2019, all of it, mild steel included, is treated as carcinogenic.
Spray-booth and prep-bay extraction at Maesteg bodyshops and repairers. 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 college teaching rooms, workshops and testing labs across the borough, to the containment their work demands.
On the ground in Maesteg
We are out under Maesteg's extraction every week. The proof that matters is the jobs, not a stock photo.
The weld-fume arms at a busy Maesteg MOT garage were falling short of benchmark, and a poorly sealed duct joint was dragging performance down. We recorded benchmark readings, checked capture at each hood by eye and swapped out a tired filter, then cleared the debris sitting in the ducting. Once that was gone the system met its control standards on re-test. Full test documentation was handed over, and we were in and out inside the day so staff barely noticed us.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Maesteg 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 Ewenny Road Industrial 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 Maesteg 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.
Across most Maesteg sites - the Ewenny Road Industrial Estate plant and the smaller units alike - it is the fourteen-month interval that trips people up, because a lapsed test leaves the system non-compliant from that date whatever its real condition. We run the examination, mark every hood with its result and next-due date, and produce the report your insurer or an HSE inspector will look for, and any failed point comes back with its reading, its cause and the fix rather than a bare red tag.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Maesteg 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 Maesteg duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Village Farm 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.
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 Ewenny Road Industrial 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. Each hood is labelled with its status and next-due date, and you get the HSG258 report and system schematic for your COSHH file - the record an HSE inspector visiting a Ewenny Road Industrial Estate unit will ask to see.
Yes. A new spray booth or fume-arm install at a Maesteg 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.
Yes. We plan testing around production shifts at the Ewenny Road Industrial Estate units, term-time access at the Maesteg university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Ewenny Road Industrial Estate and Village Farm Industrial Estate and across the wider Bridgend.
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 Ewenny Road Industrial Estate or a smaller Maesteg workshop needs for their COSHH file.
Local knowledge
The Llynfi Ironworks and its sister works turned a scatter of farms holding about four hundred people in 1821 into a township of several thousand within twenty years, and when the iron failed the collieries at Coegnant, Caerau, Garth and St John's carried the valley on until the last pit closed in 1985. That heritage of metal, machinery and heavy engineering still runs through the workshops of the Llynfi Valley, 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. It is the same instinct that built the valley, applied to the air the workforce breathes.
