Uxbridge · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Uxbridge workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Uxbridge
Uxbridge is the historic market town and civic heart of the London Borough of Hillingdon, at the far western edge of Greater London where the Grand Union Canal and the River Colne mark the old Middlesex border with Buckinghamshire. Deep beneath it lies the Battle of Britain Bunker, the underground No. 11 Group operations room from which Fighter Command directed the air war in the summer of 1940.
Its working economy runs on precision engineering, food and drink and the fabrication trades, much of it grouped in the light-industrial units of the Uxbridge Industrial Estate and Trade City Business Park, alongside major employers like the Coca-Cola Europacific Partners GB headquarters and Brunel University London.
Each of those Uxbridge 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 Uxbridge Industrial Estate units to the one-bench Uxbridge 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 Uxbridge and the rest of Greater London it is the evidence COSHH expects you to hold.
Oil-mist and coolant-mist extraction on CNC machining centres and turning shops across the Uxbridge Industrial Estate and Trade City Business Park, where light manufacturing has taken over from the town's old milling trade.
Steam canopies and flour-dust control in the bakeries and food units of west Hillingdon, in a town whose beverage trade Coca-Cola Europacific Partners still runs from its GB headquarters on Bakers Road.
Fine-dust extraction and downdraught tables at Uxbridge cabinet shops and joinery works, where hardwood and MDF dust is captured at the tool before it reaches the lungs.
On-torch extraction, fume arms and downdraught benches across the town's industrial units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at the bodyshops off Cowley Road and the industrial estates. 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 laboratories of Brunel University London and Hillingdon Hospital, to the containment their work demands.
On the ground in Uxbridge
We are out under Uxbridge's extraction every week. The proof that matters is the jobs, not a stock photo.
A busy ceramics studio in Uxbridge had its cutting bench hoods under-performing against benchmark, with a partly blocked filter on the unit. We ran velocity and smoke tests across the hoods, sorted a leaking connection and re-checked each point. Capture came back within benchmark once the fault was cleared, and we handed the report over on completion. The visit was scheduled for the weekly closed day when the studio was shut.
The test
Under HSG258 a statutory LEV test is no visual once-over. For an Uxbridge 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 Uxbridge 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 an Uxbridge 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.
On most Uxbridge sites - the Uxbridge Industrial Estate units and the smaller workshops alike - it is the fourteen-month clock that bites: let it lapse and the system is non-compliant that day, however well it seems to run. We examine it, tag each hood with its status and next-due date, and hand over the report an HSE inspector or insurer will want. Where something fails you get the reading, the cause and the remedy - never just a red sticker.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Uxbridge 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 Uxbridge duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Trade City 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. A new spray booth or fume-arm install at an Uxbridge 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.
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 Uxbridge, but an Uxbridge Industrial Estate fabrication shop and a High Street canopy are kept as the separate jobs they are.
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 Uxbridge Industrial Estate or a smaller Uxbridge workshop needs for their COSHH file.
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 an Uxbridge Industrial Estate unit will ask to see.
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 Uxbridge Industrial Estate and Trade City Business Park and across the wider Greater London.
Yes - the industrial estates and workshops around Uxbridge Industrial Estate and Trade City Business Park, the university and hospital labs, and the wider Greater London.
Local knowledge
Following excavations in 1938, engineers sank an operations room sixty feet beneath RAF Uxbridge, and from that bunker No. 11 Group Fighter Command ran the world's first integrated air-defence system through the Battle of Britain and on into D-Day. That instinct for precision and control still runs through the machine shops on the town's industrial estates, and every one of them carries a duty to capture the mist, fume and dust its work throws off. We test and certify local exhaust ventilation to the standard COSHH sets, so the extraction reads true against its design figures.
