Workplace Air Monitoring Sheffield

Air monitoring for Sheffield workplaces

Sheffield's metals and fabrication base is unusually specialised: forging, heat treatment, speciality steels, cutting tool manufacture and precision machining sit alongside traditional foundries. The resulting exposures are heavy on metal fume, hot-work by-products and grinding dust rather than the light assembly exposures found in other cities.

Foundry work brings respirable crystalline silica from sand systems, knockout and fettling — one of the highest-risk silica environments in UK industry — plus carbon monoxide around furnaces and cupolas, and metal fume during pouring.

Rotherham and the Advanced Manufacturing Park add powder metallurgy, additive manufacturing and composites, where fine metal powders require both exposure monitoring and explosive atmosphere awareness. We pair sampling with LEV assessment because extraction on grinding and fettling stations is usually the deciding control.

Exposures we commonly measure in Sheffield

Every survey is scoped to your own processes, but these are the exposures that most often drive monitoring programmes across Sheffield and South Yorkshire.

Respirable crystalline silica from foundry sand, knockout and fettling
Metal fume during pouring, welding, forging and heat treatment
Grinding, linishing and abrasive wheel dust in tool and blade manufacture
Metalworking fluid mist from machining and honing cells
Carbon monoxide and combustion gases around furnaces and cupolas

What workplace air monitoring covers

Workplace air monitoring measures what your employees actually breathe during normal work. Under Regulation 10 of the Control of Substances Hazardous to Health Regulations 2002 (COSHH), employers must monitor exposure where it is needed to protect health, where a workplace exposure limit could be exceeded, or where control measures need to be shown to be working.

We sample dusts, fumes, vapours, mists and gases — including respirable crystalline silica, welding fume, inhalable and respirable dust, solvent vapours and process chemicals — using calibrated pumps worn in the breathing zone across a representative full shift, supported by static sampling to map sources around the workplace.

Samples are analysed by an accredited laboratory using the relevant MDHS or ISO method and compared with the workplace exposure limits published in HSE guidance note EH40. Compliance is judged using the BS EN 689 statistical framework rather than a single reading, and short-term (15-minute) sampling is added wherever peak tasks matter.

You receive an occupational hygiene report setting out measured concentrations, the compliance position, the adequacy of controls such as local exhaust ventilation, practical recommendations and a defined re-monitoring interval — evidence that stands up to HSE, insurers and client audits.

Sheffield air monitoring FAQs

Why is silica monitoring so important in Sheffield foundries?

Sand systems, knockout and fettling release respirable crystalline silica with a workplace exposure limit of just 0.1 mg/m³ over eight hours. Exposure can exceed that limit within a couple of hours of fettling, so personal sampling is the only reliable way to prove control.

Can you sample during a single forging or pouring campaign?

Yes. Where a high-exposure task runs only occasionally we schedule attendance for that campaign and report both the task-based and shift-averaged exposure, which is the fair way to assess intermittent heavy work.

Do you monitor metalworking fluid mist in South Yorkshire machine shops?

We do. Mist is sampled as oil mist or water-mix aerosol depending on the fluid, and we comment on fluid management and bacterial contamination because both affect respiratory risk alongside the airborne concentration.

Will your report satisfy an HSE metals sector inspection?

It is written for that purpose — BS EN 689 compliance decisions, clear exposure limit comparisons, control adequacy findings and a defined re-monitoring interval.
