Application of Chemical Shower System in Laboratory
Application of Chemical Shower System in Laboratory
Application background: The chemical shower system is a key protective equipment in high-level biosafety laboratories, used for disinfecting personnel wearing protective clothing to prevent contamination after leaving high pollution areas.
System function: Mainly used in positive pressure protective clothing biosafety laboratories to clean and disinfect the surface of protective clothing, effectively inactivate and remove potentially contaminated dangerous pathogenic microorganisms, and ensure the safe exit of personnel from polluted environments.
Equipment composition: It mainly includes three parts: the overall chemical shower compartment, the automatic liquid and chemical dosing system, and the intelligent PLC control device. Through the automatic proportioning of chemical agents, they are sprayed onto protective clothing without dead corners using nozzles.
Performance testing: The chemical shower system needs to undergo strict performance testing, including 7 mandatory items such as box airtightness, high-efficiency filter leak detection, etc., to ensure that the system operates in good condition and improve safety during use.
The application of chemical shower systems in laboratories is of great significance for ensuring the safety of laboratory personnel and public health safety.
Disinfection effect and evaluation of chemical shower system
Disinfection effect verification: The chemical shower system comprehensively cleans and disinfects the surface of protective clothing through specific disinfectants and spraying methods. Research has shown that, while ensuring the qualified disinfection effect of the system, appropriate flushing water pressure, flushing time, and the type and concentration of disinfectant can be determined to achieve effective disinfection.
Professional evaluation: Although chemical shower systems have certain disinfection effects in specific scenarios (such as high-level biosafety laboratories), their application in public places (such as community entrances) has been questioned. Disease control experts point out that inappropriate disinfection methods are not only ineffective, but may also pose potential hazards to human health, such as irritating the skin and respiratory mucosa.
In summary, the disinfection effect of chemical shower systems is reliable under specific conditions, but their application should follow professional guidance to avoid blind use. In public places, more scientific and reasonable disinfection methods should be chosen to ensure public health and safety.
