Sandhurst · COSHH / HSG258
Statutory thorough examination and testing of local exhaust ventilation for Sandhurst workshops and production sites, keeping fume and dust control compliant with COSHH and HSE guidance HSG258.
Sandhurst
Sandhurst sits in the far south-eastern corner of Berkshire, a commuter town of around twenty-one thousand people grown together from the four old villages of Central Sandhurst, College Town, Little Sandhurst and Owlsmoor. Its name is known across the world for the Royal Military Academy, where every officer in the British Army has trained since the college moved here from Marlow in 1813, its College Town Gate opening straight onto Yorktown Road.
Away from the parade square the town works through light engineering, food production and the fabrication trades, much of it grouped in the units at Yorktown Industrial Estate and Lakeside Business Park off Swan Lane.
Wherever a Sandhurst 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 Yorktown Industrial Estate units down to the smallest Sandhurst 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 Sandhurst and across Berkshire it stands as their COSHH evidence.
Oil-mist and coolant-mist extraction on CNC machining centres and turning shops across the Yorktown Industrial Estate and the technology and defence-engineering firms strung along the Blackwater Valley towards Camberley and Farnborough.
Steam canopies and flour-dust control in Sandhurst bakeries and commercial kitchens, and the high-volume catering plant that feeds cadets and staff at the Royal Military Academy through every day of the training year.
Fine-dust extraction and downdraught tables at local cabinet shops and joinery works, where hardwood and MDF dust is captured at the tool before it reaches the lungs.
On-torch extraction, fume arms and downdraught benches across the Yorktown and Lakeside units. Since the HSE's 2019 reclassification, all welding fume - mild steel included - is treated as carcinogenic.
Spray-booth and prep-bay extraction at Sandhurst and College Town 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 science and technical laboratories at the Royal Military Academy and the research and test firms that grew from the old Royal Aircraft Establishment work in the valley, to the containment their work demands.
On the ground in Sandhurst
We are out under Sandhurst's extraction every week. The proof that matters is the jobs, not a stock photo.
A family-run MOT garage in Sandhurst had lost control at the exhaust bay, the tailpipe extraction reels let down by a worn fan impeller. We measured face and capture velocities, ran smoke tests point by point and inspected the fan and filter. Clearing debris from the ducting brought capture back within benchmark, all readings logged and reported. The supervisor kept the coffee topped up through the morning.
The test
A statutory LEV test to HSG258 is far more than a look round. On a Sandhurst system it settles three questions: is the ductwork and plant intact, does it still capture at the hood, and does that capture still match the design.
Ductwork, hoods, filters, fans and dampers checked for damage, blockage and leakage across the Yorktown 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 Sandhurst line.
Where exposure is in question - a precision engineering and 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.
Across most Sandhurst sites - the Yorktown 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 Sandhurst 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 Sandhurst duty-holder.
Each system tagged with status and next-due date, so compliance is visible on the Lakeside Business Park 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 precision engineering and manufacturing bay, a food and drink production 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 Yorktown Industrial Estate unit will ask to see.
Yes - the industrial estates and workshops around Yorktown Industrial Estate and Lakeside Business Park, the university and hospital labs, and the wider Berkshire.
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 Sandhurst, but a Yorktown Industrial Estate fabrication shop and a Yorktown 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 Yorktown 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.
precision engineering and manufacturing, food and drink production, woodworking and joinery, welding and fabrication, vehicle body and paint, and laboratory fume cupboards - the trades clustered around Yorktown Industrial Estate and Lakeside Business Park and across the wider Berkshire.
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 Yorktown Industrial Estate or a smaller Sandhurst workshop needs for their COSHH file.
Local knowledge
Ambarrow Court, the Victorian house in Little Sandhurst, was taken over by the Royal Aircraft Establishment in 1940 and used for aeronautical work until 1969, one thread of the defence-engineering culture that still runs down the Blackwater Valley towards Farnborough. That instinct survives in the machine shops and technology firms of Yorktown and Lakeside, and every one of them carries a duty to control the mist, fume and dust its work throws off. We test and certify local exhaust ventilation to the standard COSHH sets, so the extraction reads true against its design figures.
