Ripley · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Ripley workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Ripley
Ripley is a market town of around 22,000 people in the Amber Valley, seven miles north-east of Derby, that grew from a medieval market charter into one of the powerhouse towns of the Derbyshire coalfield. Its name is bound up with the Butterley Company, the ironworks and engineering firm founded here in 1790 whose wrought iron still holds up the train-shed roof of St Pancras Station.
Its working economy today runs on engineering, manufacturing and the fabrication trades, much of it grouped in the industrial units at Peasehill Business Park and the Codnor Gate Industrial Estate on the edge of town.
Each of those Ripley processes throws fume, dust, mist or vapour into the workplace air, and COSHH demands it is captured at source - that capture system is local exhaust ventilation, and it must be thoroughly examined and tested at least every fourteen months. We cover the lot, from the Peasehill Business Park units to the one-bench Ripley workshops, taking capture and face-velocity readings and leaving a clear pass or remedial verdict with the hoods labelled.
By sector
Any system that draws fume, dust, mist or vapour off at source counts as LEV, and across Ripley and the rest of Derbyshire it is the evidence COSHH expects you to hold.
Oil-mist and coolant-mist extraction on CNC machining centres and turning shops, the modern heirs of the Butterley Company engineering works that once cast bridges, boilers and the ironwork for St Pancras.
Steam canopies and flour-dust control in the bakeries, butchers and food units around Ripley and the Peasehill Business Park, where airborne dust and vapour are captured before they reach the lungs.
Fine-dust extraction and downdraught tables at Ripley cabinet shops and joinery works, where hardwood and MDF dust is drawn off at the tool before it can hang in the air.
On-torch extraction, fume arms and downdraught benches across the Codnor Gate and Peasehill units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Ripley 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 schools, colleges and technical labs around Ripley and Amber Valley, to the containment their work demands.
On the ground in Ripley
We are out under Ripley's extraction every week. The proof that matters is the jobs, not a stock photo.
The tailpipe extraction reels at an established Ripley vehicle workshop were under-performing against benchmark, with a filter well overdue for replacement. We carried out a full thorough examination and test, taking velocity readings, running smoke visualisation and checking the filter. Once a worn impeller was sorted every point passed on re-test. A compliance report went into the HSE file, and we scheduled the visit for a Sunday when the shop was shut.
The test
Under HSG258 a statutory LEV test is no visual once-over. For a Ripley 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 Peasehill 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 Ripley 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
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.
For the great majority of Ripley sites, from the Peasehill 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 Ripley 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 Ripley duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Codnor Gate 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.
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 Ripley, but a Peasehill Business Park fabrication shop and a Grosvenor Road canopy are kept as the separate jobs they are.
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 Peasehill Business Park and Codnor Gate Industrial Estate and across the wider Derbyshire.
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 Peasehill Business Park or a smaller Ripley workshop needs for their COSHH file.
Yes - the industrial estates and workshops around Peasehill Business Park and Codnor Gate Industrial Estate, the university and hospital labs, and the wider Derbyshire.
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 Peasehill Business Park unit will ask to see.
Yes. A new spray booth or fume-arm install at a Ripley 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.
Local knowledge
Benjamin Outram and Francis Beresford formed the Butterley Company in 1790, and within a year the first cold-blast furnace was in blast on the coal, ironstone and clay that lay under Ripley. The works grew into one of the great engineering firms of the age, forging the wrought-iron ribs that still carry the train-shed roof over St Pancras Station in London. That instinct for metal still runs through Ripley's machine shops and fabrication units, 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 extraction reads true against its design figures.
