Paisley · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Paisley workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Paisley
Paisley is Scotland's largest town, home to around 77,000 people on the western edge of Glasgow, and a place whose name the world already knows - from the swirling Paisley Pattern and the Coats and Clark thread mills to the twelfth-century Abbey that cradled the Stewart dynasty.
Its working economy runs on precision engineering, food and drink and the fabrication trades, much of it grouped in the industrial units at Hillington Park and Phoenix Business Park close to Glasgow Airport.
Each of those Paisley 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 Hillington Park units to the one-bench Paisley workshops, taking capture and face-velocity readings and leaving a clear pass or remedial verdict with the hoods labelled.
By sector
Any system that draws fume, dust, mist or vapour off at source counts as LEV, and across Paisley and the rest of Renfrewshire it is the evidence COSHH expects you to hold.
Oil-mist and coolant-mist extraction on CNC machining centres, from the Rolls-Royce aero-engine heritage at Hillington to the precision shops feeding the Inchinnan aerospace cluster by Glasgow Airport.
Steam canopies and flour-dust control in Renfrewshire's bakeries and the whisky blending and bottling halls that Chivas Brothers and Douglas Laing built the town's trade on.
Fine-dust extraction and downdraught tables at Paisley 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 Hillington Park and Phoenix Business 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 Paisley 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 and the Royal Alexandra Hospital, to the containment their work demands.
On the ground in Paisley
We are out under Paisley's extraction every week. The proof that matters is the jobs, not a stock photo.
An electronics bench in Paisley had the airflow at its solder-fume extract tips falling since the last test, pointing to a leaking flexible connection. We took benchmark readings, visualised capture at each hood and freed a slipping belt, then re-checked each point. One tip failed at first on debris in the ducting and passed after remedial work, and we issued a signed HSG258 report.
The test
Under HSG258 a statutory LEV test is no visual once-over. For a Paisley system it has to answer three things - whether the system is sound, whether it still draws at the hood, and whether that draw holds to what it was designed to deliver.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Hillington 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 Paisley line.
Where exposure is in question - an aerospace and precision engineering 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 Paisley sites - the Hillington Park 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 Paisley 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 Paisley duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Phoenix Business 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. An aerospace and precision engineering 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.
aerospace and precision engineering, food and drink production, woodworking and joinery, welding and fabrication, vehicle body and paint, and laboratory fume cupboards - the trades clustered around Hillington Park and Phoenix Business Park and across the wider Renfrewshire.
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 Hillington Park production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
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 Hillington Park or a smaller Paisley workshop needs for their COSHH file.
Yes - the industrial estates and workshops around Hillington Park and Phoenix Business Park, the university and hospital labs, and the wider Renfrewshire.
Yes. A new spray booth or fume-arm install at a Paisley 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 Hillington Park units, term-time access at the Paisley university labs, and normal hours at smaller workshops, so the examination never stops the line.
Local knowledge
The government built a shadow factory at Hillington in 1939, and by 1943 Rolls-Royce was turning out four hundred Merlin and Griffon aero-engines a week there before the plant finally closed in December 2005. That precision-engineering instinct still runs through Paisley's machine shops and aerospace suppliers, 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.
