LEV Testing · Carlton
The Colwick Industrial Estate by the Trent runs food, distribution and engineering plant that raises dust, fume and mist the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
Carlton sits beside the Colwick Industrial Estate, one of Nottingham's larger working estates along the Trent. Its food-production and distribution units, its engineering and joinery workshops all raise dust, fume or mist, and each depends on local exhaust ventilation that captures it at source.
LEV falls out of tune unseen - filters load, ducts fur, fans tire - until a hood no longer controls the exposure. We carry out thorough examination and testing to HSG258 across Carlton: measured capture and face velocities at the working points, a verdict against the system's intended performance, and a label whose next-due date holds.
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 food-production unit on the Colwick estate, the extraction drawing off flour and powder dust needed its thorough examination. We measured capture at each point, found a loaded filter dropping the velocity, set the fix and re-tested before certifying.
A Carlton joinery's wood-dust system serving the saws and sanders had lost pull. We measured capture at the tools, checked the ducting and fan, 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, 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 Colwick Industrial Estate units and the workshops across Carlton, and the wider Nottinghamshire.
No - flour and powder dust, wood and metal dust, welding fume, spray booths, mist extraction, fume cupboards and salon and dental extraction all fall under the same duty.
The Colwick estate keeps much of east Nottingham's food production, distribution and engineering working, unit after unit raising a dust, fume or mist its LEV has to draw off where it is made. We test to HSG258 so those workshops can prove their extraction controls what their people breathe.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Nottinghamshire 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 Nottinghamshire.
