Explosion-proof lighting selection is part of safety engineering and must follow project area classification and applicable requirements. An ordinary fixture IP rating does not replace explosion protection.
Suppliers can support model checks, while hazardous classification, design and final compliance should be completed by qualified project professionals.
Confirm gas or dust risk
Collect hazardous medium, release source, ventilation and zone information; different risks lead to different product scopes.
- Separate gas and dust
- Record zone and equipment boundaries
- Confirm ambient temperature and corrosion
Check markings and temperature class
Markings must match project requirements, and surface temperature must not become an ignition source.
- Do not rely on product names
- Check nameplate and documents
- Reconfirm range in high ambient temperature
Include mounting and wiring
Brackets, boxes, cable entries and installation quality affect the complete system.
- Confirm mounting orientation
- Leave service clearance
- Handle grounding and sealing as required
Close documentation before purchase
Create a pre-order list for models, markings, test or certification documents, instructions and acceptance files.
- Match model and documents
- Recheck changes
- Keep site acceptance records
