LEV Testing · Bebington
Bromborough and the Wirral International Business Park run chemical, food and engineering plant that raises fume, mist and dust the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
Bebington sits next to some of the Wirral's heaviest industry. Bromborough and the Wirral International Business Park run chemical processing, food manufacturing and engineering, from the Unilever heritage of Port Sunlight onward, and every process that raises fume, mist or dust depends on local exhaust ventilation that captures it at source.
LEV drifts out of tune unseen, its filters loading and its fan tiring until a hood no longer controls the exposure. We carry out thorough examination and testing to HSG258 across Bebington - 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 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 processing plant on the Bromborough estate, the extraction drawing off process vapour and mist needed its thorough examination. We measured capture at the points and the transport velocity through the system, set out what to correct, and re-tested to confirm control before certifying.
A unit on the business park needed its weld-fume arms testing. We measured capture at each arm, flagged one running slow, and re-tested after the fix 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.
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 condition of the hoods, ducting, filter and fan and how each is meant to control its process.
We measure capture and face velocities, transport velocity and static pressure at every key point.
The readings are judged against the design benchmark under HSG258, with a clear pass or fail on control.
The plant is labelled and you get the report and next-due date for your COSHH records.
At least every 14 months for most systems, more often for higher-risk processes. 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 Bromborough and Wirral International Business Park units and the workshops across Bebington, and the wider Merseyside.
No - process vapour and mist, welding fume, metal and wood dust, spray booths, fume cupboards and salon and dental extraction all fall under the same duty.
Bromborough and the Wirral International Business Park keep a large share of Merseyside's chemical, food and engineering industry working, each plant raising a vapour, mist or dust its LEV has to draw off at source. We test to HSG258 so those sites can prove their extraction controls what their people breathe.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Merseyside 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 Merseyside.
