LEV Testing · Blyth
From the wind-blade composite hall to the engineering and finishing units, Blyth workplaces raise fume, mist and dust that the law says must be controlled - and the control proven by a thorough examination and test.
Blyth's port has made itself the home of offshore-wind manufacture, and a composite hall among it moulds and finishes turbine blades in glass and epoxy. Where a hall infuses resin and grinds cured blade the vapour and dust are real - the epoxy and styrene off the infusion and the fine glass dust off the grinding both sit in the breathing zone across a blade the length of a football pitch - and the estates' engineering and finishing units add weld fume, oil mist and grinding dust, all things a worker should not breathe.
Local exhaust ventilation is what captures it at source, and the law does not take the control on trust. Under COSHH the extraction has to be thoroughly examined and tested at least every 14 months, measured against how it is used - not just switched on and assumed to work.
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 wind-blade composite hall on the Blyth port estate, infusing resin and grinding cured blade, the extraction over the infusion bays and the grinding stations had lost capture and resin vapour and glass dust were hanging over the hall. We measured capture at the infusion bays and each grinding station, checked the ducting and the filters, and found a fan below duty dragging the run. We set out the remedial action, and re-tested to confirm the control before certifying.
At an engineering unit on the Cowpen estate near Blyth, the weld-fume arms and mist extraction over the machining had lost capture and the shop was hazing by mid-shift. We measured capture and face velocities at each point, checked the ducting and the filters, and reported what needed putting right so it held its spec on a re-test.
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 under COSHH Regulation 9 - and sooner for certain higher-risk processes. We set the right interval for what you run and put the next-due date on the label and the report.
A thorough-examination-and-test report against HSG258, a pass/fail on each point with any remedials listed, and a dated label on the plant showing when the next test falls due.
We set out exactly what failed and why - often a single reading such as static pressure or capture velocity - so it can be put right, and we re-test to confirm the control before certifying.
Yes - the the Kitty Brewster and Cowpen estates and the town's units, and across Blyth and the wider Northumberland.
No - any LEV: welding fume arms, wood and grain dust systems, spray booths, mist extraction, fume cupboards, and dental and salon extraction all fall under the same duty and the same clock.
Blyth builds turbine blades and drives its renewables trade from the port beside the Cowpen and Kitty Brewster engineering units, infusing resin, grinding composite, welding and machining - raising resin vapour, glass dust, weld fume and mist. Every one carries a duty to control what its work throws off - and to prove it with a measured test.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Northumberland 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 Northumberland.
