Doncaster · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Doncaster workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Doncaster
Doncaster is a South Yorkshire city of around 308,000 that gained city status in 2022, grown on the Great Northern Railway's locomotive Plant Works.
The heavy work is rail and advanced engineering - the rolling-stock and heavy engineering of the Plant heritage, the advanced manufacturing and fabrication, and the food manufacturing - with the logistics parks of West Moor Park and iPort and the bodyshops between them.
Every one of those Doncaster 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 West Moor Park units to the smaller Doncaster 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 Doncaster and the rest of South Yorkshire it is the evidence COSHH expects you to hold.
Grinding-dust, weld-fume and paint extraction across the rolling-stock and heavy-engineering shops, a trade rooted in the Doncaster Plant, where metal dust and fume need capture at source.
Machining, grinding and fume extraction across the advanced-manufacturing and fabrication units, where metal dust and mist need capture proven.
Flour-dust, steam and mist extraction across the food producers, where organic dust is both a health and a combustion risk.
On-torch extraction, fume arms and downdraught benches across the West Moor Park and iPort units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Doncaster 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 University Centre Doncaster and Doncaster Royal Infirmary, to the containment their work demands.
On the ground in Doncaster
We are out under Doncaster's extraction every week. The proof that matters is the jobs, not a stock photo.
A rail locomotive maintenance depot in Doncaster had a grinding-dust extraction bench with its heavy cast-iron surface grates completely plugged with hardened filings and slag. We cleared the grate slots with a wire brush, checked the collector hopper had capacity and measured the face-pull velocities. It passed once the grates were clear, with the downdraught reaching a solid 0.5 metres per second across the working zone. It is an active railway depot, so trackside safety protocols and high-visibility PPE were mandatory throughout.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Doncaster 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 West Moor 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 Doncaster line.
Where exposure is in question - a rail and heavy 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 Doncaster sites - the West Moor 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 Doncaster 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 Doncaster duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the iPort 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 rail and heavy engineering bay, an advanced manufacturing and fabrication bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
Yes. A new spray booth or fume-arm install at a Doncaster 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 West Moor Park production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
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 West Moor Park unit will ask to see.
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 West Moor Park or a smaller Doncaster workshop needs for their COSHH file.
Yes. We plan testing around production shifts at the West Moor Park units, term-time access at the Doncaster university labs, and normal hours at smaller workshops, so the examination never stops the line.
Yes - the industrial estates and workshops around West Moor Park and iPort, the university and hospital labs, and the wider South Yorkshire.
