Dumfries · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Dumfries workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Dumfries
Dumfries is the Queen of the South, the largest town in the south of Scotland, a red sandstone burgh of around 33,000 people set on the banks of the River Nith. It is the town where Robert Burns spent his last years, dying here in 1796 and lying buried in the mausoleum at St Michael's.
Its working economy runs on manufacturing, engineering and food production, much of it grouped in the units at Heathhall Industrial Estate and along Irongray Road and Tinwald Downs Road, from Gates' power-transmission belt plant to the DuPont Teijin Films works at Cargenbridge.
Every one of those Dumfries 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 Heathhall Industrial Estate units to the smaller Dumfries workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
Any system that draws fume, dust, mist or vapour off at source counts as LEV, and across Dumfries and the rest of Dumfries and Galloway it is the evidence COSHH expects you to hold.
Oil-mist and coolant-mist extraction on lathes and machining centres, from the Gates rubber and power-transmission belt plant on Tinwald Downs Road to the engineering shops that grew out of the town's Arrol-Johnston motor heritage at Heathhall.
Steam canopies and flour-dust control in the Dumfries bakeries and food producers packed into the Heathhall and Irongray Road units, where dairy-rich Galloway produce is prepared and packed.
Fine-dust extraction and downdraught tables at Dumfries 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 Heathhall and Irongray Road units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Dumfries 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 Dumfries and Galloway College at the Crichton, the Royal Infirmary at Cargenbridge and the DuPont Teijin Films polyester-film plant, to the containment their work demands.
On the ground in Dumfries
We are out under Dumfries's extraction every week. The proof that matters is the jobs, not a stock photo.
A long-established joinery workshop in Dumfries found the extraction on its router table had lost its pull, which came down to a leaking flexible connection. We put the system through a full thorough examination and test, taking velocity readings, running smoke visualisation and checking the filters. Once the connection was sealed every point passed on re-test, and we drew up a compliance report for the HSE file. We timed the visit for half-term while the bay was quiet.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Dumfries 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 Heathhall 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 Dumfries 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
The duty is written into COSHH Regulation 9: where LEV controls a hazardous substance, the employer must have it thoroughly examined and tested at least every fourteen months and keep the records for five years.
For the great majority of Dumfries sites, from the Heathhall Industrial 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 Dumfries 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 Dumfries duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Irongray Road 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.
Yes - the industrial estates and workshops around Heathhall Industrial Estate and Irongray Road Industrial Estate, the university and hospital labs, and the wider Dumfries and Galloway.
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 Heathhall Industrial Estate and Irongray Road Industrial Estate and across the wider Dumfries and Galloway.
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 Heathhall Industrial Estate unit will ask to see.
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 Heathhall 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.
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 Dumfries, but a Heathhall Industrial Estate fabrication shop and a High Street canopy are kept as the separate jobs they are.
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 Heathhall Industrial Estate or a smaller Dumfries workshop needs for their COSHH file.
Local knowledge
In 1913 Arrol-Johnston built a vast new car works at Heathhall on the northern edge of Dumfries, designed by the American architect Albert Kahn and said to be the first ferro-concrete factory in Britain, raised by a firm whose founders had built one of the earliest petrol cars made in the country. That engineering instinct still runs through the town, where Gates makes rubber power-transmission belts on Tinwald Downs Road and machine shops across Heathhall and Irongray Road turn, weld and finish metal. Every one of them carries a duty to control the oil 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.
