Grimsby · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Grimsby workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Grimsby
Grimsby is a North East Lincolnshire port town of around 86,000, once the world's largest fishing port and now the UK's largest seafood-processing centre.
The signature trade is seafood and food processing - the Grimsby seafood cluster of more than fifty factories - alongside offshore-wind operations at the port and the chemical and cold-storage trades, across the South Humberside Industrial Estate and Pyewipe, with the bodyshops between them.
Wherever a Grimsby 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 South Humberside Industrial Estate units down to the smallest Grimsby workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
Any system that draws fume, dust, mist or vapour off at source counts as LEV, and across Grimsby and the rest of Lincolnshire it is the evidence COSHH expects you to hold.
Steam, smoke and mist extraction across the seafood and food-processing factories, a trade at the heart of the Grimsby cluster, where organic dust and vapour need capture at source.
Weld-fume and grinding extraction across the offshore-wind operations and maintenance bases at the port, where metal fume needs capture proven.
Vapour, ammonia and mist extraction across the chemical and cold-storage plants, where process vapour needs capture at source.
On-torch extraction, fume arms and downdraught benches across the South Humberside Industrial Estate and Pyewipe units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Grimsby bodyshops. 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 Grimsby Institute and Diana, Princess of Wales Hospital, to the containment their work demands.
On the ground in Grimsby
We are out under Grimsby's extraction every week. The proof that matters is the jobs, not a stock photo.
A fish-processing and freezing plant in Grimsby had the local extraction slots on an ammonia packaging line caked with frozen ice from an unsealed line. We defrosted the slot manifolds with a localised heat gun, cleared the ice blockage and measured the system static pressures. It passed once defrosted, with the slot velocity back to its design criteria. It was a sub-zero environment, so the test tools had to be acclimated slowly to stop condensation forming on the sensor elements.
The test
An HSG258 statutory LEV test goes well beyond a walk-round look. On a Grimsby 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 South Humberside 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 Grimsby line.
Where exposure is in question - a seafood and food processing process, say - sampling confirms whether control is actually protecting the people at the process.
The duty
COSHH Regulation 9 makes it plain: any LEV controlling exposure to a hazardous substance has to be thoroughly examined and tested at intervals no greater than fourteen months, and the resulting records kept for at least five years.
Across most Grimsby sites - the South Humberside 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 Grimsby 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 Grimsby duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Pyewipe 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 seafood and food processing bay, an offshore wind and energy bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
Seafood and food processing, offshore wind and energy, chemicals and cold storage, welding and fabrication, vehicle body and paint, and the labs of the institute and hospital - the trades clustered around South Humberside Industrial Estate and Pyewipe and across the wider Lincolnshire.
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 South Humberside Industrial Estate unit will ask to see.
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 Grimsby, but a South Humberside Industrial Estate fabrication shop and a Freeman 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 South Humberside Industrial Estate or a smaller Grimsby workshop needs for their COSHH file.
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 South Humberside Industrial Estate production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
Yes. A new spray booth or fume-arm install at a Grimsby 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.
