Hamilton · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Hamilton workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Hamilton
Hamilton is the administrative capital of South Lanarkshire, a town of around 53,000 people on the south-eastern edge of Glasgow, and the seat of the Dukes of Hamilton whose Hamilton Palace was once the largest private house in Britain - larger even than Buckingham Palace. Its domed Mausoleum, raised for the tenth Duke, still holds the longest echo of any man-made structure in the world.
Its working economy runs on precision engineering, food and drink and the fabrication trades, much of it grouped in the units at Hamilton International Technology Park at Blantyre and Whistleberry Industrial Park, alongside a large public sector centred on the council headquarters on Almada Street.
Every one of those Hamilton 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 Hamilton International Technology Park units to the smaller Hamilton workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
If a process captures fume, dust, mist or vapour at source, that capture system is LEV - and across Hamilton and the wider South Lanarkshire it is your evidence under COSHH.
Oil-mist and coolant-mist extraction on CNC machining centres and press shops, from the high-value engineering firms at Hamilton International Technology Park to the fabrication units around Whistleberry and Blantyre.
Steam canopies and flour-dust control in the bakeries, butchers and food producers that supply Lanarkshire, where extraction keeps heat, moisture and airborne dust off the shop floor.
Fine-dust extraction and downdraught tables at Hamilton 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 Whistleberry and Technology Park units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Hamilton 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 the University of the West of Scotland Lanarkshire campus and New College Lanarkshire, to the containment their teaching and research demand.
On the ground in Hamilton
We are out under Hamilton's extraction every week. The proof that matters is the jobs, not a stock photo.
An established joinery workshop in Hamilton had the capture velocity at several of its saw and sander hoods sitting below benchmark, with a filter long overdue for changing. We logged benchmark readings, visualised the capture at each hood and sorted a slipping drive belt. Once the debris in the ducting was cleared every point passed on re-test, and we handed over a signed report along with a few tips for the foreman on keeping things clear between visits.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Hamilton 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 Hamilton International Technology Park 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 Hamilton 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 most Hamilton sites - from the Hamilton International Technology Park units to the smaller workshops - the fourteen-month clock is the one that bites: miss it and the system is non-compliant the day it lapses, whatever its condition. We examine, label each hood with its status and next-due date, and issue the report an HSE inspector or your insurer will ask to see. If something fails, you get the reading, the cause and the fix - not just a red sticker.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Hamilton 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 Hamilton duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Whistleberry Industrial Park 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.
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 Hamilton, but a Hamilton International Technology Park fabrication shop and a Quarry Street canopy are kept as the separate jobs they are.
Yes. A new spray booth or fume-arm install at a Hamilton 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.
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 Hamilton International Technology Park and Whistleberry Industrial Park and across the wider South Lanarkshire.
Yes - the industrial estates and workshops around Hamilton International Technology Park and Whistleberry Industrial Park, the university and hospital labs, and the wider South Lanarkshire.
Yes. We plan testing around production shifts at the Hamilton International Technology Park units, term-time access at the Hamilton 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 Hamilton International Technology Park or a smaller Hamilton workshop needs for their COSHH file.
Local knowledge
By the early twentieth century more than forty coal pits had been sunk around Hamilton, feeding the ironworks, steam engines and railways that industrialised Lanarkshire and eventually undermined the ground beneath Hamilton Palace itself. That heavy-engineering inheritance still runs through the machine shops and fabrication units at Hamilton International Technology Park and Whistleberry, where cutting, grinding and welding throw off mist, dust and fume. Each of them carries a duty to control what its work puts into the air. We test and certify local exhaust ventilation to the standard COSHH sets, so the extraction reads true against its design figures.
