Colwyn Bay · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Colwyn Bay workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Colwyn Bay
Colwyn Bay sweeps around a three-mile crescent of sand on the North Wales coast, a Victorian and Edwardian seaside resort that grew almost overnight once the Chester and Holyhead Railway reached it, the station opening in 1849. From the Pwllycrochan Estate that sold the first building plots in the 1870s to the Welsh Mountain Zoo set on the hillside above the town, it is a place built for visitors as much as residents.
Its working economy leans on light manufacturing, engineering and the trades, much of it grouped in the units at Mochdre Commerce Park beside the A55 and along the coast at Tir Llwyd Industrial Estate in Kinmel Bay.
Every one of those Colwyn Bay processes puts fume, dust, mist or vapour into the air, and COSHH requires it controlled at source - which means local exhaust ventilation, thoroughly examined and tested at least every fourteen months. We test the LEV across all of it - from the Mochdre Commerce Park units to the smaller Colwyn Bay workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
A system that catches fume, dust, mist or vapour at the point it is released is LEV, and for Colwyn Bay employers and others across Conwy it is the record COSHH looks for first.
Oil-mist and coolant-mist extraction on CNC machining centres, from the engineering firms expanding at Tir Llwyd Industrial Estate to the light-manufacturing units that fill Mochdre Commerce Park beside the A55.
Steam canopies and flour-dust control in the bakeries, food producers and cold-store operations working out of Mochdre Commerce Park and the trade units along the coast road.
Fine-dust extraction and downdraught tables at Colwyn Bay cabinet shops and joinery works in Mochdre and Old Colwyn, 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 fabrication units at Mochdre Commerce Park and Tir Llwyd. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at bodyshops around Builder Street and the Mochdre 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 science rooms at Coleg Llandrillo in Rhos-on-Sea and for local healthcare and veterinary settings, to the containment their work demands.
On the ground in Colwyn Bay
We are out under Colwyn Bay's extraction every week. The proof that matters is the jobs, not a stock photo.
An independent cabinet maker in Colwyn Bay had its saw and sander hoods under-performing against benchmark, with debris built up in the ducting. We checked static pressure, cleared the slipping belt and re-tested each point against benchmark. Every point passed on re-test once the worn impeller was sorted, with a signed report. We timed the job for the summer break while the unit was quiet.
The test
A statutory LEV test to HSG258 is far more than a look round. On a Colwyn Bay 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 Mochdre Commerce 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 Colwyn Bay 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.
For most Colwyn Bay sites - from the Mochdre Commerce Park units to the smaller workshops - the fourteen-month clock is the one that bites: miss it and the system is non-compliant the day it lapses, whatever its condition. We examine, label each hood with its status and next-due date, and issue the report an HSE inspector or your insurer will ask to see. If something fails, you get the reading, the cause and the fix - not just a red sticker.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Colwyn Bay 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 Colwyn Bay duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Tir Llwyd 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.
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 Mochdre Commerce Park production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
Yes. We plan testing around production shifts at the Mochdre Commerce Park units, term-time access at the Colwyn Bay university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Mochdre Commerce Park unit will ask to see.
Yes - the industrial estates and workshops around Mochdre Commerce Park and Tir Llwyd Industrial Estate, the university and hospital labs, and the wider Conwy.
Yes. A new spray booth or fume-arm install at a Colwyn Bay 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.
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 Mochdre Commerce Park or a smaller Colwyn Bay workshop needs for their COSHH file.
Local knowledge
The Welsh Mountain Zoo opened above the town in 1963, the work of the Jackson family, and today it is the National Zoo of Wales spread across a thirty-seven-acre hillside with the Carneddau at its back. A visitor town still runs on real engineering behind the scenes, from the machine shops at Tir Llwyd to the fabrication units at Mochdre, and every one carries a duty to control the mist, fume and dust its work throws off. We test and certify local exhaust ventilation to the standard the regulations set, so the extraction reads true against its design figures.
