Bathgate · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Bathgate workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Bathgate
Bathgate sits on the M8 corridor midway between Edinburgh and Glasgow, a West Lothian town of around twenty thousand people with an outsized place in industrial history. It was here that James 'Paraffin' Young completed his chemical works in 1851 - the first truly commercial oil works anywhere in the world - and here that Sir James Young Simpson, the pioneer of chloroform anaesthesia, was born in 1811.
Its working economy today runs on engineering, food production and the fabrication trades, much of it grouped in the units at Whiteside Industrial Estate, Starlaw Business Park and the Whitehill estate on Inchmuir Road.
Wherever a Bathgate 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 Whiteside Industrial Estate units down to the smallest Bathgate workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
Where fume, dust, mist or vapour is pulled away at the point it is made, that is LEV - and for employers in Bathgate and across West Lothian it stands as their COSHH evidence.
Oil-mist and coolant-mist extraction on CNC machining centres and lathes across the Whiteside and Whitehill units, in a town whose shale-oil chemistry and later truck-building gave it a deep engineering grain.
Steam canopies, oven-hood and flour-dust control in the bakeries and food-production units around Bathgate and the wider West Lothian estates that supply the central-belt trade.
Fine-dust extraction and downdraught tables at the Bathgate joinery and cabinet workshops, 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 Starlaw Business Park and Whiteside Industrial Estate units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Bathgate bodyshops, in a town that built British Leyland trucks and tractors for a quarter of a century. 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 electronics, optics and testing houses on the Whitehill estate and across West Lothian, to the containment their work demands.
On the ground in Bathgate
We are out under Bathgate's extraction every week. The proof that matters is the jobs, not a stock photo.
A popular upholstery workshop in Bathgate had face velocity across its extraction hoods reading low, traced to a partly blocked filter on the unit. We ran velocity and smoke tests across the hoods, then sorted a worn impeller before re-checking. With that done all points passed on re-test, and we left readings and a report for the file. We arranged a recurring six-monthly clean to keep it in check.
The test
Under HSG258 a statutory LEV test is no visual once-over. For a Bathgate 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 Whiteside 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 Bathgate 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 Bathgate sites - the Whiteside 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 Bathgate 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 Bathgate duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Starlaw 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.
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 Bathgate, but a Whiteside Industrial Estate fabrication shop and a Hopetoun Street canopy are kept as the separate jobs they are.
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 Whiteside Industrial Estate unit will ask to see.
Yes. We plan testing around production shifts at the Whiteside Industrial Estate units, term-time access at the Bathgate university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Whiteside Industrial Estate and Starlaw Business Park and across the wider West Lothian.
Yes. A new spray booth or fume-arm install at a Bathgate 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.
Yes - the industrial estates and workshops around Whiteside Industrial Estate and Starlaw Business Park, the university and hospital labs, and the wider West Lothian.
Local knowledge
James 'Paraffin' Young completed his works at Bathgate in 1851, the first truly commercial oil works anywhere in the world, distilling paraffin and lubricating oils from the shale and torbanite mined out of West Lothian. The red bings that still ridge the landscape are the spoil of that trade, and at its height the shale industry supported tens of thousands of people across the county. That refining instinct set the pattern for the engineering and process work that followed, and every one of those trades carries a duty to control the mist, fume and dust it throws off. We test and certify local exhaust ventilation to the standard COSHH sets, so the extraction reads true against its design figures.
