Chorley · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Chorley workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Chorley
Chorley is a Lancashire market town of around 37,000, famous for the Chorley cake and the Flat Iron open-air market, with a manufacturing base rooted in the former Royal Ordnance Factory at Buckshaw.
The signature trade is engineering and logistics - the advanced manufacturing of Buckshaw Village, the distribution of the M6 and M61, and the food manufacturing - across the Buckshaw Village and Matrix Park estates, with the bodyshops between them.
Wherever a Chorley 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 Buckshaw Village units down to the smallest Chorley workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
Any system that draws fume, dust, mist or vapour off at source counts as LEV, and across Chorley and the rest of Lancashire it is the evidence COSHH expects you to hold.
Machining, grinding and fume extraction across the advanced-manufacturing and engineering units of Buckshaw Village, where metal dust and mist need capture at source.
Battery-charging, weld-fume and paint extraction across the M6 and M61 distribution parks, where the maintenance and fabrication bays need capture proven.
Steam, dust and mist extraction across the food producers of the Chorley-cake town, where organic dust is both a health and a combustion risk.
On-torch extraction, fume arms and downdraught benches across the Buckshaw Village and Matrix Park units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Chorley 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 the local college and Chorley and South Ribble Hospital, to the containment their work demands.
On the ground in Chorley
We are out under Chorley's extraction every week. The proof that matters is the jobs, not a stock photo.
An engineering works on Buckshaw Village in Chorley had an oil-mist extraction unit over a machining cell letting a fine coolant haze escape because the coalescing filter had loaded solid. We measured the capture at the enclosure and checked the mist-collector differential. It failed on the saturated filter and the mist breakthrough, even with the fan pulling to spec. The cell machined at load, so the swarf and coolant were handled to the housekeeping standard during the test.
The test
A statutory LEV test to HSG258 is far more than a look round. On a Chorley system it settles three questions: is the ductwork and plant intact, does it still capture at the hood, and does that capture still match the design.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Buckshaw Village 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 Chorley line.
Where exposure is in question - an engineering and advanced manufacturing process, say - sampling confirms whether control is actually protecting the people at the process.
The duty
Under Regulation 9 of COSHH the obligation sits squarely with the employer - any LEV that controls a hazardous substance needs a thorough examination and test at least every fourteen months, and the records held for five years.
Across most Chorley sites - the Buckshaw Village 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 Chorley 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 Chorley duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Matrix 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 engineering and advanced manufacturing bay, a logistics and distribution bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
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 Buckshaw Village 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 Buckshaw Village or a smaller Chorley workshop needs for their COSHH file.
Yes. We plan testing around production shifts at the Buckshaw Village units, term-time access at the Chorley university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Chorley, but a Buckshaw Village fabrication shop and a Flat Iron canopy are kept as the separate jobs they are.
Yes - the industrial estates and workshops around Buckshaw Village and Matrix Park, the university and hospital labs, and the wider Lancashire.
Engineering and advanced manufacturing, logistics and distribution, food manufacturing, welding and fabrication, vehicle body and paint, and the labs of the college and hospital - the trades clustered around Buckshaw Village and Matrix Park and across the wider Lancashire.
