Because explosion-proof equipment is used in environments with flammable and explosive hazards, the equipment itself must not become a source of ignition, meet the relevant test requirements of explosion-proof standards, which is a basic requirement for safe production. The national explosion-proof standard GB/T 3836 also stipulates that equipment used in hazardous areas must pass inspections and certifications by national authorities. Additionally, flammable and explosive hazardous areas are subject to regular inspections as per AQ 3009-2007, requiring the installation and use of equipment and products that have passed explosion-proof certification. The maintenance and care process should also refer to the requirements of the explosion-proof standards.

Products requiring an explosion-proof certificate typically need to provide electrical schematics, assembly diagrams, structural drawings, label diagrams, BOM sheets, manuals, corporate standards, etc. For explosion-proof equipment with plastic casings, wireless functionality, laser emissions, batteries, etc., corresponding technical documents or inspection reports are also required.
