LEV Testing · West Molesey
The trade units around the Moleseys and the wider Elmbridge area weld, machine and spray, raising fume, mist and dust the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
Beyond the riverside, the Moleseys and the wider Elmbridge area keep their trade units and workshops working. The engineering units, the joineries and the vehicle bodyshops around West Molesey and toward Walton raise fume, mist or dust, and each depends on local exhaust ventilation that captures it at source.
An LEV system quietly loses its edge - filters load, ducts fur, a fan tires - until a hood no longer controls what a worker breathes. We carry out thorough examination and testing to HSG258 across West Molesey: measured capture and face velocities at the working points, a verdict against the system's intended performance, and a label with 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.
At a joinery near West Molesey, the wood-dust extraction serving the saws and sanders had lost pull. We measured capture at the tools, checked the ducting and fan, set the fix, and re-tested before certifying.
A bodyshop in the Moleseys needed its spray booth testing. We measured the booth airflow and capture, checked the filters, and labelled the plant 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.
The point of a thorough examination and test is to prove the extraction still controls the exposure - so we measure it, we do not eyeball it. Condition, capture and face velocities, transport velocity and static pressure are checked against the design intent under HSG258, and the result is written up and labelled on the plant.
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 examine the hoods, ducting, filter and fan and identify how each is meant to control its process.
We record capture and face velocities, transport velocity and static pressure at every key point.
The readings are assessed against the design intent under HSG258, with a clear verdict on control.
The plant is labelled with the result and next-due date, and you get the report for the COSHH file.
At least every 14 months for most systems, more often for higher-risk work. We set the interval to the process and label it on the plant.
Condition of hoods, ducts, filters and fan; measured capture and face velocities; transport velocity and static pressure - all against how the LEV should perform to control the exposure.
We set out exactly what failed - often one reading - so it can be put right, and re-test to confirm control before certifying.
Yes - the workshops around West Molesey and the wider Elmbridge area, and across Surrey.
No - wood and metal dust, welding fume, spray booths, mist extraction, fume cupboards and salon and dental extraction all fall under the same duty.

The workshops around the Moleseys and toward Walton keep the area's joinery, engineering and vehicle trades going, each raising a dust, fume or mist its LEV has to draw off at source. We test to HSG258 so those units can prove their extraction controls what their people breathe.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Surrey 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 Surrey.
