Daventry · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Daventry workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Daventry
Daventry is a historic market town of around 28,000 in Northamptonshire, sitting at the heart of the UK's logistics Golden Triangle, anchored by the vast Daventry International Rail Freight Terminal and the former Daventry calling transmitting station on Borough Hill.
The signature trade is logistics and engineering - the rail-freight distribution, the power-systems and advanced manufacturing, and the food and general fabrication - across the Royal Oak Industrial Estate and Drayton Fields estates, with the bodyshops between them.
Wherever a Daventry 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 Royal Oak Industrial Estate units down to the smallest Daventry 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 Daventry employers and others across Northamptonshire it is the record COSHH looks for first.
Battery-charging, forklift-exhaust and vehicle-maintenance extraction across the vast rail-freight terminal and its warehousing, the defining trade of the town, where the charging rooms and maintenance bays need capture at source.
Engine-test-cell exhaust, weld-fume and paint-mist extraction across the power-systems and engineering plant, where the test cells and fabrication lines need capture proven.
Cooking-fume, weld-fume and cutting-fluid-mist extraction across the food-production and metalworking units of the estates, where the cooklines and benches each need their own capture.
On-torch extraction, fume arms and downdraught benches across the Royal Oak Industrial Estate and Drayton Fields units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Daventry 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 local college and the Danetre Hospital, to the containment their work demands.
On the ground in Daventry
We are out under Daventry's extraction every week. The proof that matters is the jobs, not a stock photo.
A power-systems engineering plant in Daventry had an engine-test extraction over a test cell pulling weak, letting exhaust fume linger in the bay. We measured the capture at the tailpipe extraction and checked the ducting and fan for losses. It failed on the low capture and the fume breakthrough, and we specified the remedial work. The cell ran large diesel engines under load, so the exhaust-fume monitoring backed up the airflow test.
The test
An HSG258 statutory LEV test goes well beyond a walk-round look. On a Daventry 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 Royal Oak 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 Daventry line.
Where exposure is in question - a rail-freight and distribution 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 Daventry sites - the Royal Oak 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 Daventry 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 Daventry duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Drayton Fields Industrial Estate 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 rail-freight and distribution bay, a power-systems and advanced manufacturing 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 a Royal Oak 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 Daventry, but a Royal Oak Industrial Estate fabrication shop and a High Street canopy are kept as the separate jobs they are.
Yes - the industrial estates and workshops around Royal Oak Industrial Estate and Drayton Fields Industrial Estate, the university and hospital labs, and the wider Northamptonshire.
Yes. We plan testing around production shifts at the Royal Oak Industrial Estate units, term-time access at the Daventry 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 Daventry 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.
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 Royal Oak 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.
