Do not choose an “ATEX machine” from the product name alone. The site must assess dangerous substances, releases, ventilation, ignition sources and zones; the machinery specification must match that documented environment and complete installation.
Why this matters
DSEAR covers workplace fire and explosion risks. A project needs substance data, process conditions, zoning, equipment selection, static control, earthing, ventilation, inspection and operating procedures.
Decision table
| Input | Why it matters | Evidence |
|---|---|---|
| Substance data | Flash point, vapour, dust and concentration affect risk | Current SDS and process data |
| Release assessment | Normal and foreseeable releases influence zoning | DSEAR assessment |
| Area classification | Defines zone extent and equipment requirement | Classification drawing |
| Ignition control | Electrical, mechanical, static and hot surfaces matter | Equipment schedule |
| Inspection | Selection can be undermined by installation or maintenance | Inspection records |
Information to collect first
- Provide current SDS and actual concentration.
- Describe filling temperature, pressure and cleaning fluids.
- Define normal, abnormal and maintenance releases.
- Obtain area classification before equipment selection.
- Review static from product and containers.
- Include pumps, coding, conveyors and extraction.
Recommended method
- 1
Complete the site DSEAR assessment.
- 2
Issue zone and equipment requirements to suppliers.
- 3
Confirm every installed device in the zone.
- 4
Plan earthing, extraction and inspection.
- 5
Verify the installed system before use.
Common mistakes to avoid
- Using flash point as the only decision factor.
- Buying one certified component and calling the machine suitable.
- Ignoring container static or ancillary equipment.
- Changing formulation or ventilation without reassessment.
- Assuming a general-purpose fan is acceptable.
Questions people also ask
Who defines the zone?
The workplace dutyholder should arrange a competent DSEAR assessment and hazardous-area classification.
Do water-based products remove risk?
Not automatically; review ingredients, cleaning media, vapours, gases, powders and temperatures.
Does DSEAR cover combustible dust?
Yes. Dust clouds and deposits can create fire and explosion hazards.
What should a supplier confirm?
The precise equipment scope, category, protective methods, assumptions and documentation for the defined environment.
