LEV Testing · Wilmslow
Wilmslow's technology and analytical-instrument firms run laboratory, soldering and precision processes, raising fume, mist and dust the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
Wilmslow's working side is unusually high-tech - the town is a long-standing home of analytical-instrument and mass-spectrometry manufacture, alongside laboratories and precision-engineering units. Their fume cupboards and bench extraction, soldering stations and machining cells all raise something a local exhaust system has to capture at source.
LEV is tested hard by laboratory and precision work and quietly loses its edge - filters load, ducts fur, a fan tires - until a hood stops holding the exposure. We carry out thorough examination and testing to HSG258 across Wilmslow: measured capture and face velocities at the working points, a judgement against how the system was meant to perform, and a label carrying a next-due date you can trust.
CNC and manual machining raises oil mist and metal dust at the enclosure and bench that has to be captured at source.
Flour, powders and steam need capture at the mixing and process points, from bakeries to production kitchens.
Saws, sanders and routers throw fine wood dust that has to be drawn off at the tool and the bench.
Weld fume and grinding dust need capture at the arm and booth, wherever steel is fabricated.
Bodyshop spray booths and prep bays carry paint mist and solvent vapour that the extraction has to hold and clear.
Fume cupboards, safety cabinets and dental and salon extraction all count as LEV and all fall due on the same clock.
Real jobs, described by sector and area - never by a client's name.
In a Wilmslow instrument laboratory, the fume cupboards and bench extraction needed their thorough examination. We measured face velocities at each cupboard and capture at the benches, found one reading low, set the fix, and re-tested before certifying.
A Wilmslow precision-electronics cell needed its solder-fume extraction testing. We measured capture at each tip, checked the airflow, and labelled the system with the readings and next-due date.
Condition of hoods, ducting, filters and fan - the damage, blockage and wear that quietly drops performance.
Measured capture and face velocities at the working points, plus transport velocity and static pressure through the system.
The readings assessed against how the LEV should perform to actually control the exposure - not just whether the fan turns.
Where the process warrants it, sampling to confirm the control is keeping the substance out of the breathing zone.
A thorough examination and test under COSHH is a real assessment, not a rubber stamp. It is a structured examination of the system's condition, measurement of its actual performance, and an assessment of those readings against how the system should perform to control the exposure. It follows the HSE's guidance, HSG258, and ends in a report and a label.
We test to the HSE's guidance, HSG258, and the job ends in a report and a label on the plant: what was measured, what passed, what needs putting right, and the date the next test falls due.
We inspect the system's condition - hoods, ducting, filter and fan - and identify how it is meant to control each process.
We take the readings: capture and face velocities, duct transport velocity and static pressure at the key points.
We assess the readings against the benchmark and set out clearly whether the system is controlling the exposure.
The system is labelled with the test result and next-due date, and you get the report for your COSHH file.
At least every 14 months for most systems, sooner for higher-risk laboratory work. We match the interval to the process and label the next-due date on the plant.
The condition of hoods, ducts, filters and fan, and measured capture, face, transport and static-pressure readings - all weighed against how the LEV should perform to control the exposure.
We set out what failed and why, usually a single reading, so it can be corrected, then re-test to confirm control before certifying.
Yes - the laboratory, instrument and precision units across Wilmslow, and the wider Cheshire.
No - fume cupboards, solder and weld fume, machining mist, metal and wood dust and salon and dental extraction all fall under the same duty.
Wilmslow's laboratories and precision units carry the town's fume-cupboard, soldering and machining work, the fume, mist and dust drawn off wherever it is raised. We test to HSG258 so those benches can prove their extraction holds what their people would otherwise breathe.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Cheshire and the UK. From a machine shop to a joinery, a spray booth or a lab fume cupboard, the job ends the same way: measured readings, a clear verdict, and a label whose next-due date you can rely on.
Tell us what you run and we will examine, measure, report and label it to HSG258 - across Cheshire.
