EXP混合/反应设备内粉尘爆炸，2 人死亡；可燃粉尘累积与点火源控制不足
可燃粉尘防爆（NFPA 652/654）执行缺陷；设备清洗/维护作业粉尘管控与点火源隔离不足
The mechanism code EXP shown on this card is the KB's internal damage-mechanism abbreviation (not an ISO 14224 code); it describes how the equipment failed. The 'ISO 14224 Mapping' block above maps it to the correct ISO functional failure code (which describes what the equipment failed to do) — these are two distinct dimensions in ISO 14224. The mechanism follows the narrative in the card body.
