Loughton · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Loughton workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Loughton
Loughton is a town of around 31,000 people on the very edge of Epping Forest, just inside the M25 and thirteen miles from Charing Cross, whose name is bound up with the ancient royal forest that Queen Victoria dedicated to the public at High Beach in 1882.
Its working economy runs on precision engineering, food production, printing and the vehicle trades, much of it grouped in the units of the Oakwood Hill Industrial Estate and along Langston Road at Debden, a short walk from the Central line.
Wherever a Loughton 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 Oakwood Hill Industrial Estate units down to the smallest Loughton workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
A system that catches fume, dust, mist or vapour at the point it is released is LEV, and for Loughton employers and others across Essex it is the record COSHH looks for first.
Oil-mist and coolant-mist extraction on CNC and machining work in the Oakwood Hill units, in a town whose manufacturing pedigree runs to the De La Rue banknote-printing plant at Debden, where the nation's notes have been printed since 1956.
Steam canopies and flour-dust control in the bakeries and food units around Debden and Langston Road, from production baking to the chilled and prepared-food trades that supply the shopping park.
Fine-dust extraction and downdraught tables at Loughton 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 Oakwood Hill Industrial Estate and the Langston Road 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 and the BMW, Mercedes and Volkswagen dealerships along Langston Road. 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 and workshops at Epping Forest College and the town's dental and clinical practices, to the containment their work demands.
On the ground in Loughton
We are out under Loughton's extraction every week. The proof that matters is the jobs, not a stock photo.
An established bakery in Loughton had the capture velocity on its flour-handling extraction dropping below benchmark, with a slipping fan drive belt at fault. We put the system through a full thorough examination and test, with velocity readings, smoke visualisation and a filter check. Once the tired filter was sorted all points passed on re-test, and the report was handed over on completion. We handed the supervisor a short photo report for their maintenance log.
The test
An HSG258 statutory LEV test goes well beyond a walk-round look. On a Loughton 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 Oakwood Hill 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 Loughton 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 Loughton sites - the Oakwood Hill Industrial 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 Loughton 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 Loughton duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the the Langston Road business area 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. 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 Oakwood Hill Industrial Estate unit will ask to see.
Yes. We plan testing around production shifts at the Oakwood Hill Industrial Estate units, term-time access at the Loughton university labs, and normal hours at smaller workshops, so the examination never stops the line.
Yes. A new spray booth or fume-arm install at a Loughton 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 Oakwood Hill Industrial Estate or a smaller Loughton workshop needs for their COSHH file.
Yes - the industrial estates and workshops around Oakwood Hill Industrial Estate and the Langston Road business area, the university and hospital labs, and the wider Essex.
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 Oakwood Hill Industrial Estate and the Langston Road business area and across the wider Essex.
Local knowledge
In 1954 the Bank of England began building a new banknote printing works at Debden, and production of the nation's notes started there in March 1956, the freshly extended Central line running past the plant straight into the City. That precision-manufacturing instinct still runs through Loughton's machine shops and the print and engineering units around Oakwood Hill, 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 so the extraction reads true against its design figures.
