Explosive atmosphere cleaning that protects your people, your site, and your compliance record

If your site handles flour, sugar, wood dust, metal powders, or any other material that becomes combustible once it’s airborne, standard cleaning equipment simply isn’t safe to use. A conventional vacuum can generate the exact spark or static discharge needed to ignite a dust cloud.

At The Sweeping Company, we provide explosive atmosphere cleaning for commercial and industrial sites across Somerset, Bristol, and the South West. Using ATEX vacuum equipment rated for the correct zone classification, we carry out combustible industrial dust cleaning safely, thoroughly, and in line with your DSEAR obligations — helping you protect your workforce and stay on the right side of UK law.

This service sits alongside our existing commercial offering, including CCTV chimney surveys and high-level cleaning, giving you one point of contact for the parts of your building maintenance that carry real safety consequences if they’re overlooked.

Why explosive atmosphere cleaning matters

Combustible dust builds up faster than most people realise. Flour, wood dust, sugar, and metal powders can settle on ledges, ducting, and equipment surfaces long before anyone notices. Once disturbed and airborne in the right concentration, that dust becomes a genuine explosion risk.
Standard vacuums are an ignition risk, not a solution. Off-the-shelf equipment isn’t designed to control sparking, static discharge, or surface temperature. Using it in a zoned area doesn’t just breach your DSEAR duties — it actively creates the hazard you’re trying to remove.
Regular cleaning is a legal control measure, not good housekeeping. Under DSEAR, keeping hazardous areas clear of dust accumulation is one of the practical steps employers are expected to take to reduce risk. A documented cleaning schedule using the right equipment forms part of your evidence of compliance.

Understanding ATEX and DSEAR

Because these terms get used interchangeably — often incorrectly — it’s worth being clear on what each one actually means and what it requires of you.

What does ATEX stand for?

ATEX comes from the French atmosphères explosibles, meaning explosive atmospheres. It refers to two EU directives covering environments where explosive gas, vapour, mist, or dust may be present: one governing the equipment manufacturers must produce, and one governing the precautions employers must take. In practice, “ATEX equipment” is shorthand for equipment certified safe to use in these hazardous areas — including the ATEX hoover and vacuum systems we use on site.

Does ATEX still apply to the UK?

Yes. Since Brexit, the ATEX framework has been carried over into UK law rather than dropped. Equipment placed on the UK market now needs UKCA marking rather than CE marking, but the technical requirements, zone classifications, and equipment categories work exactly as they did before. For UK employers, the practical obligations haven’t changed — only the certification mark has.

What is the difference between DSEAR and ATEX?

ATEX is the underlying European framework, now incorporated into UK law. DSEAR — the Dangerous Substances and Explosive Atmospheres Regulations 2002 — is how that framework is applied in the UK, and it’s the piece of legislation your business is actually assessed against. DSEAR places the legal duty on you as an employer to assess your risks, classify hazardous areas into zones, and control ignition sources — which is where ATEX-certified equipment comes in. When we talk about ATEX vacuuming, we’re talking about the equipment you need to meet your DSEAR obligations, not a separate compliance regime.

What are the penalties for ATEX violations?

DSEAR is enforced by the HSE, and breaches are treated as a criminal matter rather than a paperwork issue. Inspectors can issue improvement notices, prohibition notices that shut down operations immediately, or refer cases for prosecution. Serious breaches can result in unlimited fines, and in cases involving gross negligence or a fatality, individuals — including directors and safety managers — can face imprisonment. Beyond the legal exposure, incidents involving non-compliant equipment or poor housekeeping routinely void insurance cover, leaving businesses personally liable for damage and compensation claims.

When should combustible dust be cleaned?

As soon as it starts to accumulate, not once it becomes visible or a problem. Dust layers as thin as a millimetre across a large surface area can generate enough airborne material to create an explosive atmosphere if disturbed. The right approach is a scheduled cleaning programme — frequency set by your DSEAR risk assessment and how quickly dust builds up in your specific process — rather than a reactive one. Ledges, overhead beams, ducting, and enclosed voids are the areas most often missed, and the ones most likely to cause problems.

Our ATEX vacuuming and combustible dust cleaning services

We work with businesses across a range of sectors where explosive atmospheres are a recognised risk, including:

Food and beverage manufacturing (flour, sugar, starch, grain dust)
Woodworking and joinery (sawdust and MDF dust)
Biomass and solid fuel operations
Warehousing and industrial units with high-level dust accumulation
Sites with ducting, extraction systems, or enclosed voids prone to dust build-up
Any commercial premises requiring a documented DSEAR cleaning routine

Wherever the risk exists, we bring correctly zoned ATEX vacuum equipment and a team trained to use it properly.

What to expect from The Sweeping Company

A proper risk-led assessment

We start by understanding your zone classifications and the materials involved, so the equipment and method we use is matched to the actual hazard on your site — not a generic clean.

ATEX-certified equipment and trained operators

Our team uses correctly rated ATEX vacuum systems for the zones we’re working in, and we follow the anti-static and procedural controls that come with working in hazardous areas.

Documentation you can show an inspector

Every job comes with a written record of what was cleaned, when, and how — evidence you can point to as part of your DSEAR compliance, not just a tidy site.
