The revised process plan adds a flammable-vapor release zone around general-purpose equipment. What must occur before operation?
- APaint the equipment red
- BIncrease breaker ratings
- CAssume existing equipment remains suitable
- Reclassify and use suitable equipment

Classification follows the actual material, release conditions, ventilation, and extent of the hazardous area. Equipment selection, sealing, wiring methods, and maintenance must match that result; paint or breaker size cannot create an explosion-protection listing.
