Acid Mist Guides

Resources · Resources overview

The acidmist.co.uk guides hub is a structured reference library for UK occupational hygiene, health & safety and process teams managing acid mist, corrosive vapour, alkaline aerosol and reactive chemical exposure under COSHH and HSE EH40. Each cluster below points to the working pages on this site that explain the substance, the sampling method, the LEV control and the compliance evidence in detail.

Acid mist basics

Start here for the fundamentals of acid mist generation, behaviour and risk in UK workplaces. These pages cover what acid mist is, how it differs from acid vapour and from alkaline aerosol, and why heated baths, electrolysis and gas-bubble bursting drive most of the exposure in plating, anodising, pickling, battery and chemical process work. They also frame the COSHH duty to assess and control acid mist exposure against the substance-specific EH40 limits.

Acid risk assessment under COSHH — see /acid-risk-assessment/

Specific acid and corrosive hazards

These pages cover the individual substances most commonly encountered on UK acid and corrosive sites. Each one describes generation route, EH40 context, sampling method and the controls that the LEV and process design need to deliver. Use them to scope a substance-specific COSHH assessment rather than relying on a generic acid template.

Acid air sampling and monitoring

These guides cover how acid and corrosive exposure is measured in practice — personal breathing-zone pumped sampling, impregnated filters, sorbent tubes, ion chromatography and ion-selective electrode methods, and the use of direct-reading instruments for diagnostics and short-term peaks. They explain how the result is read against the substance-specific EH40 8-hour TWA and short-term limit, and how the evidence supports the COSHH judgement.

Industry and process exposure

Acid mist and corrosive exposure profiles differ sharply by sector. These pages describe the dominant tasks, release mechanisms and control priorities for the UK industries that most commonly generate acid mist, corrosive vapour and alkaline aerosol exposure — from electroplating shops through battery manufacturing to general chemical processing.

Ventilation, LEV and extraction controls

Engineering control is the heart of COSHH on acid and corrosive duty. These pages cover LEV design and Thorough Examination under Regulation 9, dedicated acid ventilation considerations (corrosive-duty ductwork, scrubbers, drainage, make-up air) and the chemical fume extraction principles that keep operator breathing-zone exposure below EH40 limits.

Compliance, health risk and workplace exposure

These pages bring the evidence together — the COSHH compliance file, the health-risk framing used when communicating with operators and managers, and the wider workplace exposure picture across acid, corrosive and reactive substances. They are written for UK duty holders and explicitly do not provide medical diagnosis or legal guarantees.

How to use this hub

Most UK acid mist programmes start with the substance and the task, move to the sampling method and EH40 comparison, then close the loop with the LEV evidence and the COSHH compliance file. The clusters above mirror that working order. For a scoped enquiry on your site, use the contact page.
