Description

Technical Field

[0001] This invention relates to the field of equipment protection system technology, and more particularly to a protection system for flammable, explosive and toxic gases. Background Technology

[0002] Safety in flammable, explosive, and toxic gas environments has always been a major concern and headache. Current safety measures in such environments primarily focus on the following: 1. Dedicated personnel for monitoring: This is the safest method, but it consumes unnecessary human resources; 2. Posting warning signs: While this provides some protection, it may be ineffective for careless or illiterate individuals; 3. Surveillance via cameras: This method is only effective when a dedicated person is constantly monitoring the screen. Coating and dispensing equipment is widely used in the production of 3C products, participating in multiple processes such as screen coating for mobile phones. Due to the properties of adhesives, they may produce toxic or harmful gases or flammable and explosive gases such as methanol and n-heptane after evaporation. If the accumulated concentration of these gases reaches a certain level, they may cause an explosion and endanger human health. Existing equipment and safety regulations cannot eliminate the above risks, which may easily lead to safety risks and endanger the lives of operators.
