LEV Testing · Heanor
The foundries, forges and engineering shops of the Heanor Gate estate raise casting fume, grinding dust and quench mist the law says must be controlled. We examine and test local exhaust ventilation to HSG258 and certify it.
Heanor grew on coal and iron, and its metal heritage lives on in the foundries, forges and heavy-engineering shops of the Heanor Gate estate on the edge of the town. Their melting and pouring bays, fettling and grinding lines and heat-treatment tanks all raise something their local exhaust ventilation has to capture at source.
LEV is tested hard by foundry and forge 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 Heanor: 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 Heanor Gate foundry, the extraction over the pouring and fettling bays needed its thorough examination. We measured capture at each point and the transport velocity, found the pull down on one hood, set the fix, and re-tested before certifying.
A Heanor heat-treatment shop needed its quench-tank extraction testing. We measured capture at the tank edges, checked the ductwork, 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 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, sooner for higher-risk foundry and heat-treatment 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 foundry, forge and engineering units across Heanor, and the wider Derbyshire.
No - casting and fettling fume, quench mist, weld fume, machining mist and grinding dust all fall under the same duty.
The Heanor Gate foundries and forges carry the town's casting, fettling and heat-treatment trades, the fume, dust and mist of metal work drawn off wherever it is raised. We test to HSG258 so those bays 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 Derbyshire 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 Derbyshire.
