Bedford · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Bedford workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Bedford
Bedford is a Bedfordshire town on the River Great Ouse, the seat of a borough of around 185,000, with an advanced-engineering corridor running out to Cranfield and a brick-making heritage.
The work is advanced and aerospace engineering - the precision engineering and fabrication of the Bedford and Cranfield corridor, the welding and metal work, and the food and drink production - across the Priory Business Park and Woburn Road estates, with the bodyshops between them.
Every Bedford process that gives off fume, dust, mist or vapour falls under COSHH, which requires the contamination held at source by local exhaust ventilation and that LEV thoroughly examined and tested at least every fourteen months. We test right across the site, from the Priory Business Park plant to the single-bench Bedford units, logging capture and face-velocity figures and returning a clear pass-or-remedial outcome with each hood identified and labelled.
By sector
If a process captures fume, dust, mist or vapour at source, that capture system is LEV - and across Bedford and the wider Bedfordshire it is your evidence under COSHH.
Machining, grinding and fume extraction across the aerospace and precision-engineering lines of the Cranfield corridor, where metal dust and mist need capture at source.
Grinding and fume extraction across the engineering and fabrication units, where metal dust and weld fume need capture proven.
Steam, dust and mist extraction across the food and drink producers, a trade rooted in Bedford's brewing heritage, where organic dust is both a health and a combustion risk.
On-torch extraction, fume arms and downdraught benches across the Priory Business Park and Woburn 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 Bedford 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 University of Bedfordshire Bedford campus and Bedford Hospital, to the containment their work demands.
On the ground in Bedford
We are out under Bedford's extraction every week. The proof that matters is the jobs, not a stock photo.
A commercial vehicle repair workshop in Bedford had the overhead spring-reeled exhaust hose for its trucks trailing on the floor - the internal return spring had broken and the heavy hose would not retract. We secured the hose manually to test the extraction, measured the volumetric exhaust flow and logged the mechanical fault. It passed on airflow but failed on physical safety grounds because of the trip hazard from the trailing hose. The workshop had very high ceilings, so an extended telescopic pole was needed to retrieve and test the nozzle.
The test
A statutory LEV test under HSG258 is not a visual once-over. On a Bedford system it answers three things: is the system intact, does it still capture, and does that capture match what it was designed to do.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Priory Business 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 Bedford line.
Where exposure is in question - an advanced and aerospace engineering process, say - sampling confirms whether control is actually protecting the people at the process.
The duty
COSHH Regulation 9 puts a hard duty on the employer: any LEV controlling a hazardous substance must have a thorough examination and test at least every fourteen months, with records kept for five years.
On most Bedford sites - the Priory Business 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 Bedford 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 Bedford duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Woburn Road 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 advanced and aerospace engineering bay, an engineering and metal fabrication bench and a lab fume cupboard can each sit on a different interval - we set the right one for every system.
Yes - the industrial estates and workshops around Priory Business Park and Woburn Road, the university and hospital labs, and the wider Bedfordshire.
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 Priory Business Park production line we can usually fit the re-test around your shifts. We will not pass a system that does not control exposure.
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 Bedford, but a Priory Business Park fabrication shop and a St Cuthberts Street canopy are kept as the separate jobs they are.
Yes. A new spray booth or fume-arm install at a Bedford 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 Priory Business Park or a smaller Bedford workshop needs for their COSHH file.
Advanced and aerospace engineering, engineering and metal fabrication, food and drink manufacturing, welding and fabrication, vehicle body and paint, and the labs of the university campus and hospital - the trades clustered around Priory Business Park and Woburn Road and across the wider Bedfordshire.
