Bromborough · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Bromborough workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Bromborough
Bromborough sits on the eastern edge of the Wirral peninsula, on the Mersey shore between Port Sunlight and Eastham, and it may be the most consequential village in England you have never heard of - many historians place the Battle of Brunanburh of 937, the fight that forged a single English kingdom, on the low fields around it, and its very name descends from that lost Brunanburh. In the nineteenth century it became an industrial powerhouse, first through Price's Patent Candle Company's model village at Bromborough Pool and then through the Lever Brothers soap works at neighbouring Port Sunlight that grew into Unilever.
Its working economy is built on the Bromborough Port Estate, one of the largest concentrations of industry in the North West, where food, flavour, chemical and manufacturing firms sit alongside the units of Croft Business Park.
Each of those Bromborough 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 Bromborough Port Estate units to the one-bench Bromborough workshops, taking capture and face-velocity readings and leaving a clear pass or remedial verdict with the hoods labelled.
By sector
A system that catches fume, dust, mist or vapour at the point it is released is LEV, and for Bromborough employers and others across Merseyside it is the record COSHH looks for first.
Oil-mist and coolant-mist extraction on CNC machining centres and press shops across the Bromborough Port Estate, one of the largest concentrations of manufacturing floor space anywhere in the North West.
Steam canopies, spice-dust and flour-dust control at the flavour and food houses clustered on and around the port estate, from spice blenders like Seasoned Pioneers to JPL Flavour Technologies and the natural-colour and extract works that carry on Bromborough's long food-manufacturing line back to Lever Brothers.
Fine-dust extraction and downdraught tables at Bromborough cabinet shops and joinery units, where hardwood and MDF dust is captured at the tool before it can reach the lungs.
On-torch extraction, fume arms and downdraught benches across the Bromborough Port Estate and Croft Business 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 Bromborough bodyshops. Two-pack paints release isocyanates - the leading cause of occupational asthma - so booth airflow is examined against its design figure.
Fume-cupboard face-velocity testing for the specialty-chemical and product laboratories on the port estate and at the Unilever research campus at neighbouring Port Sunlight, to the containment their work demands.
On the ground in Bromborough
We are out under Bromborough's extraction every week. The proof that matters is the jobs, not a stock photo.
Capture velocity across the spray booth at a town-centre Bromborough furniture spray shop had dropped below the benchmark, with a slipping fan drive belt at the root of it. I ran velocity and smoke tests across the booth, put right the leaking connection and re-checked. Every point passed once the tired filter was replaced, and I left the readings and a report for the file. Parking was awkward on the high street, so we ran hoses in from the rear yard.
The test
An HSG258 statutory LEV test goes well beyond a walk-round look. On a Bromborough system it has to establish three things - that the plant and ductwork are sound, that the hoods still capture, and that the capture still meets the figure the system was designed around.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Bromborough Port 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 Bromborough 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 puts a hard duty on the employer: any LEV controlling a hazardous substance must have a thorough examination and test at least every fourteen months, with records kept for five years.
Across most Bromborough sites - the Bromborough Port 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 Bromborough 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 Bromborough duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Croft 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 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.
Yes. We plan testing around production shifts at the Bromborough Port Estate units, term-time access at the Bromborough university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Bromborough Port Estate or a smaller Bromborough workshop needs for their COSHH file.
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 Bromborough Port Estate and Croft Business Park and across the wider Merseyside.
Yes - the industrial estates and workshops around Bromborough Port Estate and Croft Business Park, the university and hospital labs, and the wider Merseyside.
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 Bromborough, but a Bromborough Port Estate fabrication shop and an Allport Lane canopy are kept as the separate jobs they are.
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 Bromborough Port Estate production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
Local knowledge
Lever Brothers built a margarine works at Bromborough between 1914 and 1918 and later turned it to specialist fatty-acid production, feeding soaps, polishes, printing inks, plastics and pharmaceuticals from the plant that grew into Unichema. The estate itself sprang from Lever's own Bromborough Dock, opened in 1931 and for a time the largest private dock in the world, stretching more than a mile along the Mersey. That chemical and processing instinct still runs through the Bromborough Port Estate, where every unit that throws off mist, fume or dust carries a duty to control it. We test and certify local exhaust ventilation to the standard COSHH sets, so the extraction reads true against its design figures.
