| Feature / specification | Verify hazard approval ATEX vacuums |
Assessed non-hazardous use Non-ATEX vacuums |
|---|---|---|
| Environment suitability | Hazardous areas only where the specific model is approved: Zones 1 or 2 for gas/vapour, and Zones 21 or 22 for dust. Dust-only approval does not cover gas zones. | Standard warehouses and other assessed non-hazardous areas, provided the collected material and cleaning task are suitable. |
| Ignition risks handled | Designed to control ignition sources for the specified combustible dust or gas/vapour atmosphere. Approval does not automatically permit collecting flammable liquids or vapours. | General dirt and debris within the manufacturer’s specification. No assumed protection against explosive atmospheres or combustible material hazards. |
| Construction material | Conductive or static-dissipative components and other protective measures as specified for the approved assembly. | Heavy-duty plastics, steel or stainless steel, depending on the model. Metal construction alone does not establish explosion protection. |
| Earth grounding | Specified bonding, earthing and electrical continuity across relevant components and accessories, maintained and checked as instructed. | Electrical protection appropriate to the design, such as protective earthing or double insulation. A 3-pin plug or 110 V supply does not establish ATEX suitability. |
| Motor certification | Motor and ignition-protection arrangements appropriate to the certified equipment design. Models may use protected electric motors or pneumatic power; brushless or sealed alone is insufficient. | Standard industrial motors or other power systems without assumed approval for explosive atmospheres. |
| Price point | Typically a higher investment reflecting protective design, conformity requirements and maintenance obligations. | Typically lower initial cost for suitable general maintenance tasks. Price must not override the required safety specification. |
02 / Application guide
Which vacuum does your task require?
Use these prompts to check your specification against your risk assessment. A non-hazardous room does not automatically make combustible dust safe to collect in an ordinary vacuum.
When to choose ATEX
- Your DSEAR assessment identifies a classified hazardous area requiring appropriately rated cleaning equipment.
- Explosive dust clouds or flammable gas/vapour atmospheres may occur during the task.
- Flour, sugar, wood or combustible metal dust is present: confirm the material properties and the exact equipment approval.
- Chemical processing zones require equipment matched to the relevant gas or dust group and temperature limits.
- Procurement has verified the model’s marking, declaration of conformity, instructions and approved accessories.
When Non-ATEX is sufficient
- The assessment confirms a non-hazardous area and no explosion risk from the material being collected.
- High-level general dust has been identified as suitable for the vacuum; its height or appearance alone does not establish safety.
- Warehouse cleaning involves ordinary dirt and debris within the manufacturer’s operating limits.
- External gutter cleaning involves suitable debris and wet/dry equipment, with no identified combustible material or explosive atmosphere hazard.
- The required filtration, dust exposure controls and other task-specific precautions are also satisfied.
Unsure about your dust, zone or equipment marking?
Pause equipment selection and ask a competent DSEAR assessor and the vacuum manufacturer to confirm suitability. Supply the material information, area classification, required cleaning method and proposed accessories. Also check filtration and occupational exposure requirements: ATEX approval and dust filtration class address different risks.
03 / Procurement questions
Frequently Asked Questions
Can I use a Non-ATEX vacuum in a zone-rated area?
You must not use an ordinary Non-ATEX vacuum in a classified explosive atmosphere because unsuitable equipment can introduce an ignition source and breach duties under UK DSEAR requirements. A competent person should confirm that the complete equipment specification is suitable for the assessed zone and substance before cleaning begins.
What industries strictly require ATEX-certified cleaning equipment?
Food and beverage manufacturers handling fine powders, woodworking facilities, chemical plants and pharmaceutical facilities may require appropriately rated cleaning equipment where explosive atmospheres can occur, although the requirement depends on the assessed hazard and task rather than the industry name alone. A competent DSEAR assessment should establish the area classification, material properties and equipment requirements, including the risks from flour, sugar, wood and combustible metal dusts.
Are anti-static accessories enough to make a vacuum ATEX-safe?
An anti-static hose alone does not make an ordinary vacuum ATEX compliant because suitability depends on the complete equipment assembly, its conformity documentation, ignition protection, bonding and earthing arrangements, and approved accessories. A sealed or brushless motor alone is also insufficient to establish suitability, and some ATEX vacuums use pneumatic power instead of an electric motor, so the complete system must be verified for the intended task and used according to the manufacturer’s instructions.
