Royton · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Royton workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Royton
Royton sits at the foot of the Pennines two miles north of Oldham, and it holds a genuine place in industrial history - Thorp Mill, raised beside Thorp Clough in 1764, is reckoned the first water-powered cotton mill in Lancashire. From that single carding shed the town grew into one of the densest concentrations of cotton spinning anywhere in the world, with some forty mills at its peak employing the great bulk of the population.
Cotton has gone but the working economy has not, and much of it now sits on the Salmon Fields business park and the smaller units at Moss Lane and Parkside, where distribution, bed and furniture manufacture, engineering and food logistics have taken the mills' place.
Every one of those Royton 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 Salmon Fields Business Park units to the smaller Royton workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
Where fume, dust, mist or vapour is pulled away at the point it is made, that is LEV - and for employers in Royton and across Greater Manchester it stands as their COSHH evidence.
Oil-mist and coolant-mist extraction on lathes and machining centres across the Salmon Fields and Moss Lane units, and on the furniture and bedding lines that grew up around Slumberland's manufacturing on the estate.
Steam canopies, flour-dust and cold-store ventilation in the food logistics and distribution sheds at Salmon Fields Business Village, where the town's old foodservice depots have long handled and packed produce at scale.
Fine-dust extraction and downdraught tables at Royton's cabinet shops, furniture makers 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 Salmon Fields and Parkside fabrication units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Royton bodyshops, in a town that once built lorries when Seddon Atkinson assembled vehicles at Salmon Fields. 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 school science departments, training workshops and quality labs around the town, to the containment their work demands.
On the ground in Royton
We are out under Royton's extraction every week. The proof that matters is the jobs, not a stock photo.
Royton's traditional bakery had lost capture at the dough mixer hoods, with debris clogging the ducting behind them. We logged face and capture velocities, sent smoke through each point and checked over the fan and filter. One hood failed initially on an unsealed joint and came good once we sealed it, all readings noted against benchmark. The foreman kept the coffee coming through the morning while we worked.
The test
An HSG258 statutory LEV test goes well beyond a walk-round look. On a Royton system it has to establish three things - that the plant and ductwork are sound, that the hoods still capture, and that the capture still meets the figure the system was designed around.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Salmon Fields Business 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 Royton 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 Royton sites, from the Salmon Fields Business Park 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 Royton 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 Royton duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Moss Lane 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.
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 Salmon Fields Business Park and Moss Lane Industrial Estate and across the wider Greater Manchester.
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 Salmon Fields Business Park or a smaller Royton workshop needs for their COSHH file.
Yes. We plan testing around production shifts at the Salmon Fields Business Park units, term-time access at the Royton university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Salmon Fields Business Park unit will ask to see.
Yes. A new spray booth or fume-arm install at a Royton 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.
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 Royton, but a Salmon Fields Business Park fabrication shop and a Sandy Lane canopy are kept as the separate jobs they are.
Local knowledge
When Ralph Taylor set his water wheel turning at Thorp Mill in 1764, Royton pioneered the factory system that would remake the whole region, and by the 1830s a dozen steam mills stood where farmland had been. That instinct for making and moving things survives in the engineering, furniture and distribution firms on Salmon Fields and Moss Lane today, 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.
