Workplace Air Monitoring Bristol

Air monitoring for Bristol workplaces

Bristol's aerospace and advanced engineering cluster around Filton and Patchway drives an unusual exposure mix: carbon fibre and glass reinforced composite dusts from trimming and machining, epoxy resin and hardener aerosols during lay-up, sealants and adhesives, and chromate-containing primers on legacy components.

The wider region combines this with defence electronics, a substantial food and drink sector, marine and boatbuilding activity along the Avon and Severn, and steady construction and student-accommodation development in the city itself.

Composite dust is one of the most frequently misjudged exposures we see: it is coarse enough to look harmless but generates a significant inhalable fraction, which is why we usually pair inhalable and respirable dust sampling on the same operator.

Exposures we commonly measure in Bristol

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

Carbon fibre and glass composite dust from trimming, drilling and machining
Epoxy resin, hardener and sealant aerosols during lay-up and bonding
Chromate primer and paint spray exposure on aerospace components
Styrene vapour in marine and boatbuilding laminating shops
Construction dust and silica on city-centre developments

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.

Bristol air monitoring FAQs

Is carbon fibre dust covered by a workplace exposure limit?

There is no substance-specific WEL for carbon fibre, so exposure is assessed against the general inhalable and respirable dust limits in EH40 and controlled to as low as is reasonably practicable. We report both fractions and comment on control adequacy.

Can you monitor exposure in a Bristol clean or controlled aerospace area?

Yes. Sampling pumps and media are selected to suit cleanroom and controlled-area protocols, and our hygienists work to your FOD, ESD and gowning requirements.

Do you handle resin and hardener sensitisation assessments?

We measure airborne concentrations of the relevant components and comment on skin and respiratory sensitisation risk in the report, including where health surveillance should sit alongside the monitoring programme.
