[0002] Chemical engineering refers to the technology of using chemical methods to change the composition and structure of substances or to synthesize new substances, i.e., chemical processes. Its products are chemical products, and chemical production equipment is used to produce chemical products.

[0003] In chemical production processes, the operating environment of equipment is complex and highly risky, involving high temperatures, high pressures, corrosive media, and flammable and explosive substances. However, it is common for unauthorized personnel to easily approach chemical equipment, posing significant safety hazards. On the one hand, during operation, chemical equipment may experience sudden situations such as mechanical failures or pipeline leaks, leading to material splashes and equipment explosions. Unauthorized personnel are highly susceptible to physical injuries, chemical burns, or even poisoning. On the other hand, some unauthorized personnel lack safety awareness and may enter production areas out of curiosity or by accident, disrupting normal production and potentially causing operational accidents by accidentally pressing buttons or switches. These combined factors create enormous potential risks at chemical production sites. An accident could result in personal injury, property damage, and even environmental pollution, causing incalculable impacts on enterprises and society. Utility Model Content
