1. 防爆接頭表面因螺栓固定問題而失效, 包括螺栓缺失或拧緊不足的情況.

2. 唔符合防爆表面參數, 例如接合表面的間隙不當或表面粗糙度不足.

3. Inadequacy in explosion-proof enclosure entry devices arises when rubber components and cable sizes do not meet specified standards.

4. Shell integrity compromised due to cracks leads to a failure in maintaining explosion-proof qualities.
