Havant · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Havant workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Havant
Havant is a Hampshire town on the Solent coast, around 45,000, a light-manufacturing and engineering town with a historic parchment trade and the seaside of Hayling Island in its borough.
The signature trade is manufacturing - the kitchen-appliance and electronics manufacturing, the ventilation and plastics fabrication, and the biomedical and advanced manufacturing of Dunsbury Park - across the Dunsbury Park and Brockhampton Lane estates, with the bodyshops between them.
Wherever a Havant 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 Dunsbury Park units down to the smallest Havant workshop, measuring capture and face velocity and issuing a plain pass-or-remedial result with every hood tagged.
By sector
Where fume, dust, mist or vapour is pulled away at the point it is made, that is LEV - and for employers in Havant and across Hampshire it stands as their COSHH evidence.
Solder-fume, plastics-fume and solvent extraction across the kitchen-appliance and electronics manufacturing lines, a long-standing trade of the town, where fume and vapour need capture at source.
Weld-fume, dust and vapour extraction across the ventilation and plastics-fabrication units, where process fume and dust need capture proven.
Solvent, mist and fume extraction across the biomedical and advanced-manufacturing units of Dunsbury Park, where process vapour needs capture at source.
On-torch extraction, fume arms and downdraught benches across the Dunsbury Park and Brockhampton Lane units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Havant 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 Havant and South Downs College and the Queen Alexandra Hospital, to the containment their work demands.
On the ground in Havant
We are out under Havant's extraction every week. The proof that matters is the jobs, not a stock photo.
A kitchen-appliance factory on the New Lane estate in Havant had a solder-fume and plastics-fume extraction bench on an assembly line pulling weak because a blast gate in the branch had drifted shut. We reset the gate, checked the capture at the tip and measured the branch flow. It failed at first on the low capture and passed once the gate was reopened, the fume drawn cleanly off the line. The moulding fume carried a VOC load, so vapour monitoring backed up the airflow test.
The test
Under HSG258 a statutory LEV test is no visual once-over. For a Havant 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 Dunsbury 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 Havant line.
Where exposure is in question - an appliance and electronics manufacturing 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.
On most Havant sites - the Dunsbury Park units and the smaller workshops alike - it is the fourteen-month clock that bites: let it lapse and the system is non-compliant that day, however well it seems to run. We examine it, tag each hood with its status and next-due date, and hand over the report an HSE inspector or insurer will want. Where something fails you get the reading, the cause and the remedy - never just a red sticker.
How it runs
Full visual and structural check of every hood, duct run, filter and fan across the Havant 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 Havant duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Brockhampton Lane 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. An appliance and electronics manufacturing bay, a ventilation and plastics fabrication 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 Dunsbury Park units, term-time access at the Havant university labs, and normal hours at smaller workshops, so the examination never stops the line.
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 Dunsbury Park or a smaller Havant workshop needs for their COSHH file.
Appliance and electronics manufacturing, ventilation and plastics fabrication, biomedical and advanced manufacturing, welding and fabrication, vehicle body and paint, and the labs of the college and hospital - the trades clustered around Dunsbury Park and Brockhampton Lane and across the wider Hampshire.
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 Dunsbury Park unit will ask to see.
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 Dunsbury 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 - the industrial estates and workshops around Dunsbury Park and Brockhampton Lane, the university and hospital labs, and the wider Hampshire.
