LEV Testing · London
London still makes things - Park Royal's food factories, the East End workshops, the print and creative trades and the labs all raise fume, mist and dust the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
London is not only offices and restaurants; it is one of the country's largest manufacturing centres too. Park Royal in the west is among the biggest industrial estates in Europe and a huge food-production cluster; the East End and Hackney Wick keep their workshops; the print, joinery and creative-fabrication trades run across the city; and the hospitals and universities run laboratories by the hundred. Every process that raises fume, mist or dust depends on local exhaust ventilation that controls it.
LEV is not a fit-and-forget system. Filters clog, ducts fur, fans lose pull, and a hood or fume cupboard that captured on the day it was installed can quietly stop controlling the exposure. We carry out thorough examination and testing to the HSE's guidance, HSG258, across London - measured capture and face velocities at the working points, a clear verdict against how the system should perform, and a report and label whose next-due date you can rely on.
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 plant on Park Royal, the extraction drawing flour and powder dust off the mixing and packing lines needed its thorough examination. We measured capture at each point, found a loaded filter dropping the velocity, set the fix, and re-tested to confirm the control before certifying.
In a London university laboratory, the fume cupboards needed their thorough examination. We measured face velocity across each sash opening, checked the containment and airflow, set out what to correct, and re-tested to confirm control before certifying.
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 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.
A thorough examination and test is required at least every 14 months for most systems, and more often for higher-risk processes. We set your interval to the process and label the next-due date on the plant.
For extraction, condition of hoods, ducting, filters and fan, and measured capture, face, transport and static-pressure readings; for fume cupboards, face velocity and containment - all assessed against how the system should perform to control the exposure.
We set out exactly what failed and why - often a single reading such as capture velocity or face velocity - so it can be put right, and we re-test to confirm the control before certifying.
Yes - Park Royal and the west, the East End workshops, the labs and the trades across every borough, each with its own page.
No - any LEV: flour and powder dust, welding fume, wood and metal dust, spray booths, mist extraction, fume cupboards, and dental and salon extraction all fall under the same duty and the same clock.
Park Royal, straddling the west London boroughs, is one of Europe's largest industrial estates and bakes, brews and manufactures a remarkable share of the capital's food - process after process raising dust, steam or fume that its LEV has to draw off at source. We test to HSG258 so the plants that feed London can prove their extraction controls what their people breathe.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Greater London 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 Greater London.
