Description

Technical Field

[0001] The invention relates to the field of safety warning, and in particular to a safety warning system for use areas of industrial cleaning agents. Background Art

[0002] Chemical or biological agents used in industry to remove dirt are collectively referred to as industrial cleaning agents. There are many different types of industrial cleaning agents, such as non-aqueous industrial cleaning agents and water-based industrial cleaning agents. Non-aqueous industrial cleaning agents are also solvent-based cleaning agents, such as hydrocarbon cleaning agents, white oil substitutes, trichloroethylene substitutes, etc., all belong to this category. Water-based industrial cleaning agents are mainly composed of surfactants and other various chemical agents. Water-based industrial cleaning agents are now widely used in industrial cleaning to clean various oils, stains, grease, etc. on the surface of various materials such as plastics, optical glass lenses, and metal products. At present, the solvents or solutes used in existing cleaning agents are all volatile. At the same time, since industrial cleaning agents are used in large quantities and in complex environments, such as high-concentration cleaning agents or cleaning high-temperature objects, which causes the cleaning agents to evaporate violently, the potential safety hazards when using industrial cleaning agents are further increased. Therefore, for the areas where industrial cleaning agents are used, there should be a qualified monitoring and management system to effectively monitor the safety conditions in the areas where industrial cleaning agents are used, thereby avoiding the safety hazards of industrial cleaning agents. In view of the above technical problems, this application proposes a solution. Summary of the invention
