Llanelli · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Llanelli workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Llanelli
Llanelli is a town of around 43,000 on the Loughor estuary in South Wales, the historic tinplate centre nicknamed Tinopolis and the heartland of the Scarlets rugby region, ringed by the Millennium Coastal Path.
The signature trade is metals - the steel packaging and tinplate finishing, the automotive metal-pressing, and the food manufacturing and logistics - across the Dafen Industrial Estate and Capel Hendre estates, with the bodyshops between them.
Wherever a Llanelli process releases fume, dust, mist or vapour, COSHH puts the duty on you to control it at source, and the extraction that does so is LEV - subject to a thorough examination and test at least every fourteen months. We work across the range, from the Dafen Industrial Estate units down to the smallest Llanelli workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
If a process captures fume, dust, mist or vapour at source, that capture system is LEV - and across Llanelli and the wider South Wales it is your evidence under COSHH.
Oil-mist, coating-fume and annealing-fume extraction across the tinplate coating and finishing lines of the steel-packaging works, the defining trade of Tinopolis, where hot coating and annealing throw off mist and fume that need capture at source.
Weld-fume, press-mist and grinding-dust extraction across the automotive body and metal-pressing units of the Dafen estate, where metal fume and mist need capture proven.
Cooking-fume, steam and forklift-exhaust extraction across the food producers and haulage yards, where the cooklines and vehicle bays each need their own capture.
On-torch extraction, fume arms and downdraught benches across the Dafen Industrial Estate and Capel Hendre units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Llanelli bodyshops. 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 Coleg Sir Gar and the Prince Philip Hospital, to the containment their work demands.
On the ground in Llanelli
We are out under Llanelli's extraction every week. The proof that matters is the jobs, not a stock photo.
A steel-packaging works in Llanelli had an oil-mist and coating-fume extraction over a tinplate finishing line pulling weak, letting mist drift off the strip. We measured the capture along the line and checked the mist-collector and ducting for losses. It failed on the low capture and the mist breakthrough, and we specified the remedial work. The line ran hot coating and annealing, so the mist and fume monitoring backed up the airflow test.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Llanelli 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 Dafen 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 Llanelli line.
Where exposure is in question - a steel packaging and tinplate finishing 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 Llanelli sites - the Dafen 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 Llanelli 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 Llanelli duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Capel Hendre 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 steel packaging and tinplate finishing bay, an automotive metal-pressing bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
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 Llanelli, but a Dafen Industrial Estate fabrication shop and a Stepney Street canopy are kept as the separate jobs they are.
Yes. A new spray booth or fume-arm install at a Llanelli 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.
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 Dafen 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. We plan testing around production shifts at the Dafen Industrial Estate units, term-time access at the Llanelli university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Dafen Industrial Estate or a smaller Llanelli workshop needs for their COSHH file.
Yes - the industrial estates and workshops around Dafen Industrial Estate and Capel Hendre Industrial Estate, the university and hospital labs, and the wider South Wales.
