Dewsbury · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Dewsbury workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Dewsbury
Dewsbury is the heart of the Heavy Woollen District in West Yorkshire, around 62,000, once the world centre of shoddy recycled wool and now a capital of UK bed manufacturing.
The signature trade is manufacturing - the bed and mattress making that grew from the textile trade, the recycled wool and textiles, and the engineering and metal fabrication - across the Mill Street West Industrial Estate and Shaw Cross estates, with the bodyshops between them.
Wherever a Dewsbury 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 Mill Street West Industrial Estate units down to the smallest Dewsbury workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
A system that catches fume, dust, mist or vapour at the point it is released is LEV, and for Dewsbury employers and others across West Yorkshire it is the record COSHH looks for first.
Foam-bonding vapour, fabric-fibre dust and adhesive-mist extraction across the bed and mattress lines, a modern descendant of the town's textile trade, where fibre dust and solvent vapour need capture at source.
Fibre-dust and mist extraction across the textile and recycled-wool units of the Heavy Woollen District, where fine fibre is both a health and a combustion risk.
Grinding, machining and fume extraction across the engineering and fabrication units, where metal dust and mist need capture proven.
On-torch extraction, fume arms and downdraught benches across the Mill Street West Industrial Estate and Shaw Cross units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Dewsbury 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 Kirklees College and Dewsbury and District Hospital, to the containment their work demands.
On the ground in Dewsbury
We are out under Dewsbury's extraction every week. The proof that matters is the jobs, not a stock photo.
A bed and mattress manufacturer in Dewsbury had a foam-bonding and fabric-cutting extraction hood pulling weak, letting fine fibre and adhesive vapour drift off the line. We cleared the choked hood filter, checked the collector had capacity and traversed the capture across the bench. It failed at first on the low face velocity and passed once cleared, the capture back at its design figure. The spray adhesives carried a solvent load, so vapour monitoring backed up the airflow test.
The test
Under HSG258 a statutory LEV test is no visual once-over. For a Dewsbury 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 Mill Street West 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 Dewsbury line.
Where exposure is in question - a bed and mattress 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.
Across most Dewsbury sites - the Mill Street West Industrial Estate 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 Dewsbury 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 Dewsbury duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Shaw Cross 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. A bed and mattress manufacturing bay, a textiles and recycled wool 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 Dewsbury 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 Mill Street West 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.
Bed and mattress manufacturing, textiles and recycled wool, engineering and metal fabrication, welding and fabrication, vehicle body and paint, and the labs of the college and hospital - the trades clustered around Mill Street West Industrial Estate and Shaw Cross Business Park and across 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 Mill Street West Industrial Estate unit will ask to see.
Yes - the industrial estates and workshops around Mill Street West Industrial Estate and Shaw Cross Business Park, the university and hospital labs, and the wider West Yorkshire.
Yes. We plan testing around production shifts at the Mill Street West Industrial Estate units, term-time access at the Dewsbury university labs, and normal hours at smaller workshops, so the examination never stops the line.
