LEV Testing · Haverhill
Haverhill's science and manufacturing estates run chemical, flavourings and engineering processes, raising fume, mist and dust the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
Haverhill's industrial area is unusually science-heavy for a town its size - pharmaceutical, fine-chemical and flavourings plants sit alongside engineering and fabrication units on the estates south of the centre. Their reactor and process lines, weighing and blending rooms, welding bays and fume cupboards all raise something their local exhaust ventilation has to capture at source.
LEV is tested hard by chemical and manufacturing work and quietly loses its edge - filters load, ducts fur, a fan tires - until a hood stops holding the exposure. We carry out thorough examination and testing to HSG258 across Haverhill: measured capture and face velocities at the working points, a judgement against how the system was meant to perform, and a label carrying 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.
In a Haverhill fine-chemical plant, the process extraction and fume cupboards needed their thorough examination. We measured capture at the process points and face velocities at the cupboards, found one reading down, set the fix, and re-tested before certifying.
A Haverhill fabrication unit needed its weld-fume extraction testing. We measured capture at each arm and the transport velocity, 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, sooner for higher-risk chemical and welding work. We match the interval to the process and label the next-due date on the plant.
The condition of hoods, ducts, filters and fan, and measured capture, face, transport and static-pressure readings - all weighed against how the LEV should perform to control the exposure.
We set out what failed and why, usually a single reading, so it can be corrected, then re-test to confirm control before certifying.
Yes - the process, laboratory and fabrication units across Haverhill, and the wider Suffolk.
No - process and chemical fume, fume cupboards, weld fume, machining mist and metal and wood dust all fall under the same duty.
The Haverhill science and engineering estates carry the town's process, blending and welding trades, the fume, mist and dust of chemical and manufacturing work drawn off wherever it is raised. We test to HSG258 so those lines can prove their extraction holds what their people would otherwise breathe.
We have carried out LEV thorough examination and testing to HSG258 since 2001, across Suffolk 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 Suffolk.
