Yeadon · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Yeadon workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Yeadon
Yeadon sits high on the north-west edge of Leeds, in the old Aireborough weaving district right beside Leeds Bradford Airport, and it keeps one of Yorkshire's great wartime secrets - the vast AVRO shadow factory whose roof was turfed with real grass and dummy fields so it looked like open moorland from the air.
Its working economy still turns on engineering, food production and the fabrication trades, much of it grouped in the units along the Leeds Bradford Airport Industrial Estate on Harrogate Road and the established Yeadon Business Park.
Wherever a Yeadon 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 Leeds Bradford Airport Industrial Estate units down to the smallest Yeadon 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 Yeadon and the wider West Yorkshire it is your evidence under COSHH.
Oil-mist and coolant-mist extraction on CNC machining centres, from the aircraft-engineering base that Multiflight runs at Leeds Bradford Airport to the precision shops working out of the old AVRO site on Harrogate Road.
Steam canopies and flour-dust control in the bakeries and food units on the Leeds Bradford Airport Industrial Estate and Yeadon Business Park, where airborne dust and vapour are captured before they settle.
Fine-dust extraction and downdraught tables at Yeadon and Rawdon 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 Yeadon Business Park and airport-estate units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at the bodyshops along Harrogate Road and around Rawdon. 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 engineering quality labs and college science rooms around Yeadon, to the containment their work demands.
On the ground in Yeadon
We are out under Yeadon's extraction every week. The proof that matters is the jobs, not a stock photo.
A Yeadon furniture workshop had wood-dust LEV on the sanders that wasn't pulling as it should, down to a fan not reaching its rated speed. We logged benchmark readings, visualised capture at each hood and dealt with the worn impeller. One point failed at first on a slipping belt and passed once remedied, backed by a signed HSG258 report. We flagged a worn part for the workshop manager's maintenance records.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Yeadon 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 Leeds Bradford Airport 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 Yeadon line.
Where exposure is in question - an aircraft and precision engineering 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 Yeadon sites, from the Leeds Bradford Airport 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 Yeadon 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 Yeadon duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Yeadon 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 aircraft 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.
aircraft 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 Leeds Bradford Airport Industrial Estate and Yeadon Business Park and across the wider West Yorkshire.
Yes. We plan testing around production shifts at the Leeds Bradford Airport Industrial Estate units, term-time access at the Yeadon university labs, and normal hours at smaller workshops, so the examination never stops the line.
Yes. A new spray booth or fume-arm install at a Yeadon 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 Leeds Bradford Airport 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 - the industrial estates and workshops around Leeds Bradford Airport Industrial Estate and Yeadon Business Park, the university and hospital labs, and the wider West Yorkshire.
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 Leeds Bradford Airport Industrial Estate unit will ask to see.
Local knowledge
The government raised the AVRO shadow factory at Yeadon in 1939, and by the end of the war its million and a half square feet had turned out close to 700 Lancaster bombers and more than 4,500 Ansons, with over 17,000 people working shifts around the clock. That aircraft-engineering instinct still runs through Yeadon's machine shops and the Multiflight engineering base out at Leeds Bradford Airport, and 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.
