Droylsden · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Droylsden workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Droylsden
Droylsden is a town of around 23,000 people in Tameside, on the eastern edge of Manchester where the Ashton Canal threads through the old mill quarter. It is the town where Robertson's built its Golden Shred marmalade works on Ashton Hill Lane, and where W. M. Christy and Sons of Fairfield Mills wove the world's first machine-made terry towel in 1851.
Its working economy still turns on the fabrication, engineering and light-manufacturing trades, much of it grouped in the units at the Greenside Trading Centre off Greenside Lane and the industrial premises strung along Fairfield Road near the canal.
Every one of those Droylsden 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 Greenside Trading Centre units to the smaller Droylsden workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
If a process captures fume, dust, mist or vapour at source, that capture system is LEV - and across Droylsden and the wider Greater Manchester it is your evidence under COSHH.
Oil-mist and coolant-mist extraction on CNC machining centres and turning shops in the Greenside Trading Centre and the Fairfield Road units, where fine airborne mist is drawn off at the machine before it reaches the operator.
Steam canopies, flour-dust and process extraction in Droylsden's bakeries and food units, in a town whose name was carried worldwide by the Robertson's jam and marmalade works that once stood on the canal bank.
Fine-dust extraction and downdraught tables at Droylsden cabinet shops and joinery works, where hardwood and MDF dust is captured at the tool before it can hang in the air.
On-torch extraction, fume arms and downdraught benches across the Greenside Lane and Fairfield 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 Droylsden bodyshops and vehicle repairers. 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 college teaching labs, technical workshops and quality rooms across the town, to the containment their work demands.
On the ground in Droylsden
We are out under Droylsden's extraction every week. The proof that matters is the jobs, not a stock photo.
The downdraught extraction on the treatment bench at a traditional nail bar in Droylsden had lost its pull, and a worn fan impeller was behind it. We ran the full examination and test, taking velocity readings, visualising with smoke and checking the filter. With the unsealed joint dealt with, every point cleared on re-test and a signed report followed. We arranged the work over the summer break while the salon was ticking over quietly.
The test
Under HSG258 a statutory LEV test is no visual once-over. For a Droylsden 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 Greenside Trading Centre 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 Droylsden 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
The duty is written into COSHH Regulation 9: where LEV controls a hazardous substance, the employer must have it thoroughly examined and tested at least every fourteen months and keep the records for five years.
For the great majority of Droylsden sites, from the Greenside Trading Centre units to the one-man workshops, the fourteen-month deadline is what catches people out: once it passes the system is non-compliant regardless of its actual state. We carry out the examination, label every hood with its status and next-due date, and issue the report an HSE inspector or your insurer expects to see - and if a point fails, you get the number, the cause and the fix rather than a bare fail.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Droylsden 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 Droylsden duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the the Fairfield Road industrial units 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 Greenside Trading Centre production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
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 Greenside Trading Centre and the Fairfield Road industrial units and across the wider Greater Manchester.
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 Greenside Trading Centre unit will ask to see.
Yes - the industrial estates and workshops around Greenside Trading Centre and the Fairfield Road industrial units, the university and hospital labs, and the wider Greater Manchester.
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 Greenside Trading Centre or a smaller Droylsden workshop needs for their COSHH file.
Yes. A new spray booth or fume-arm install at a Droylsden 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.
Local knowledge
W. M. Christy and Sons entered textiles in 1829 and at Fairfield Mills wove the world's first machine-made terry towel in 1851, after Henry Christy copied a looped Turkish towel on an adapted loom and turned it into the Royal Turkish towels that Queen Victoria kept on standing order. That manufacturing instinct still runs through Droylsden's engineering and fabrication shops, 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 to the standard COSHH sets, so the extraction reads true against its design figures.
