In the workshop environment disinfection of pharmaceutical factories, many companies use formaldehyde fumigation sterilization method, which is inexpensive and has strong sterilization ability. However, the disadvantages of formaldehyde, such as high toxicity, strong harm, inconvenient operation, and harm to employee health, are increasingly recognized and eliminated by more and more enterprises. European pharmaceutical companies prohibit the use of formaldehyde. Sterilization experts and practical application requirements have integrated a new workshop environment disinfection technology solution for pharmaceutical factories. This article introduces the advantages of using a dry mist hydrogen peroxide disinfection machine for environmental disinfection in pharmaceutical factory workshops, and elaborates on the principle, composition, use, and verification of the dry mist hydrogen peroxide disinfection machine system. Analyzed the issues that should be noted when selecting space sterilization equipment for environmental disinfection in pharmaceutical workshops. This article elaborates in detail on the sterilization effect, corrosiveness, residue, and other issues that pharmaceutical factory workshop environmental disinfection personnel are concerned about when using hydrogen peroxide instead of formaldehyde for space sterilization.

The application of dry mist hydrogen peroxide disinfection machine in European pharmaceutical factory workshop environment disinfection has a history of nearly 20 years, especially in recent years, the dry mist hydrogen peroxide disinfection machine has developed rapidly in the context of the EU's restriction on the use of formaldehyde space sterilization. The concept of hydrogen peroxide sterilization was first proposed for pharmaceutical factory workshops. Although it cannot be quickly popularized to various categories, we can see from the EU's abandonment of formaldehyde disinfection and sterilization that the entire industry, whether managers or participants, is trying to find a product that can replace formaldehyde for sterilization.
Validation of Sterilization Efficiency of Dry Mist Hydrogen Peroxide Disinfection Machine System
The sterilization effect of the atomized hydrogen peroxide sterilization system is verifiable. Through the challenge test of biological indicators, according to the regulations in the Chinese Pharmacopoeia, Bacillus subtilis and Bacillus subtilis thermophilic were used as the challenge test bacteria. After sterilization, the bacterial count decreased by 4-6 logarithmic units, which can prove the system's ability to kill various microorganisms in the space sterilization process.
Just increase the cost of purchasing equipment in the early stage. Solved problems: shorter downtime; Simpler and more convenient operation; Better protection of personnel and a more comfortable working environment; Beneficial for improving production efficiency and maintaining personnel stability.
In summary, with some insurmountable problems of formaldehyde fumigation being rejected by people and gradually abandoned in production, the application of hydrogen peroxide sterilization technology in the disinfection space of pharmaceutical factory workshops will be increasingly accepted and adopted by more and more people. This sterilization method, with its obvious advantages, will completely replace traditional formaldehyde fumigation. Becoming a new direction and new normal for future microbial control.
