What aspects should we pay attention to when installing an explosion-proof distribution box? The protection rating marking on an explosion-proof distribution box refers to the IP rating commonly used for electrical products, which comprises two parameters: one indicates the level of protection against solid object intrusion, and the other indicates the level of protection against water ingress.

The protection rating marking for explosion-proof distribution boxes refers to the IP rating commonly used for such products, which comprises two parameters: one indicates the level of protection against the ingress of solid objects into the enclosure, and the other indicates the level of protection against water ingress into the enclosure.
The ingress protection rating for preventing foreign objects from entering the enclosure ranges from 0 to 6.
0 indicates the product’s inherent protection; 1 indicates that it can prevent solid objects with a diameter greater than 50 mm from entering the enclosure. 2: It can prevent solid objects with a diameter greater than 12.5 mm from entering the enclosure. 3: It can prevent solid objects with a diameter greater than 2.5 mm from entering the enclosure; 4: It can prevent solid objects with a diameter greater than 1 mm from entering the enclosure; 5: Dust and dust accumulation do not impair the normal operation of the protective equipment. 6: No dust enters.
The second electrical explosion-proof distribution box features a comprehensive protection rating.
The water level entering the enclosure is 0–8.
0 indicates inherent protection. 1: No harmful effects from vertically dripping water. 2: No harmful effects from vertically dripping water when the enclosure is tilted up to 15 degrees from its normal position. 3: No harmful effects from water sprayed within a 60-degree vertical range. 4: No harmful effects from water splashed in any direction. 5: No harmful effects from water sprayed in any direction. 6: No harmful effects under heavy wave action or strong water jets. 7: Water-resistant performance. 8 means: protection against immersion.

Zhenjiang Ximenzi Conducts EHS Professional Knowledge and Internal Trainer Training
On December 12, Zhenjiang Siemens invited a professional instructor from Shanghai Qian’an Environmental Protection Company to deliver EHS (Environment, Health, and Safety) expertise training and internal trainer development sessions. More than 20 participants, including heads and supervisors of the Production Department, equipment administrators, and selected frontline employees, attended the training. The curriculum covered mechanical safety safeguards, hazard identification, and risk assessment, with an introduction to practical tools such as energy control and lockout/tagout procedures. During the session, the instructor enhanced trainees’ understanding of how unsafe behaviors lead to accidents by showing short animated videos on behavioral safety. This training marked the first phase of the company’s EHS program; going forward, Zhenjiang Siemens will implement a comprehensive EHS training plan as scheduled to further elevate the company’s EHS management standards.
