Ipswich · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Ipswich workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Ipswich
Ipswich is one of England's oldest towns, a working port of around 151,000 - the UK's leading grain export port on the River Orwell.
The work is port and agri-industry - the grain, fertilizer and agri-bulk handling at the docks, the seed and grain processing, and the engineering and fabrication of a town that built farm machinery - across Ransomes Europark and the Whitehouse estate, with the bodyshops and BT research labs around them.
Every one of those Ipswich 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 Ransomes Europark units to the smaller Ipswich workshops - with capture and face-velocity readings, a clear pass or remedial outcome and system labelling.
By sector
Where fume, dust, mist or vapour is pulled away at the point it is made, that is LEV - and for employers in Ipswich and across Suffolk it stands as their COSHH evidence.
Dust-suppression and extraction on the grain, fertilizer and agri-bulk lines at the docks, where organic and mineral dust load a duct fast.
Dust-booth and downflow extraction over the seed-coating and grain lines, where fine organic dust needs capture at source.
On-torch extraction, fume arms and downdraught benches across the engineering and fabrication units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Ipswich bodyshops. Two-pack paints release isocyanates - the leading cause of occupational asthma - so booth airflow is examined to its design figure.
Dust, steam and solvent extraction across the food and print producers, where organic dust and vapour need capture at source.
Fume-cupboard face-velocity testing for the University of Suffolk and the BT research labs at Adastral Park, to the containment their work demands.
On the ground in Ipswich
We are out under Ipswich's extraction every week. The proof that matters is the jobs, not a stock photo.
An agricultural seed-coating facility in Ipswich had the downflow dust-booth exhaust plenum packed with organic seed-dressing dust after the automatic shaker chain snapped. We logged the pressure differential across the back-wall filters and confirmed the broken shaker linkage by hand. It failed on the broken mechanism, which was letting the filters load up fast with no way to clear. The seed-treatment chemicals had bright red colorants in them, so the whole inner plenum was painted vivid crimson.
The test
An HSG258 statutory LEV test goes well beyond a walk-round look. On an Ipswich 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 Ransomes Europark 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 an Ipswich line.
Where exposure is in question - a port and agri-bulk handling process, say - sampling confirms whether control is actually protecting the people at the process.
The duty
Under Regulation 9 of COSHH the obligation sits squarely with the employer - any LEV that controls a hazardous substance needs a thorough examination and test at least every fourteen months, and the records held for five years.
For the great majority of Ipswich sites, from the Ransomes Europark 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 Ipswich 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 Ipswich duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Whitehouse 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 port and agri-bulk handling bay, a seed and grain processing bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
Yes. We plan testing around production shifts at the Ransomes Europark units, term-time access at the Ipswich university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Ipswich, but a Ransomes Europark fabrication shop and a Norwich Road canopy are kept as the separate jobs they are.
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 Ransomes Europark production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
Yes - the industrial estates and workshops around Ransomes Europark and Whitehouse, the university and hospital labs, and the wider Suffolk.
Yes. A new spray booth or fume-arm install at an Ipswich 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 Ransomes Europark or a smaller Ipswich workshop needs for their COSHH file.
