Compliance overview
Scope and applicability
This standard specifies the requirements, principles, and effect evaluation of disinfection for infectious foci. It is applicable to the disinfection of environments and items contaminated by various types of infectious diseases, including Class A, B, and C infectious diseases. It is mandatory for public health institutions, disease control centers, and medical facilities managing infectious disease outbreaks, but excludes routine sterilization of medical devices not exposed to infectious foci.
Technical requirements
The standard outlines comprehensive disinfection requirements for both concurrent and terminal disinfection processes. For concurrent disinfection, it mandates that the elimination rate of natural bacteria shall be $≥ 90\%$. Terminal disinfection requires strict pathogen eradication from contaminated surfaces, air, and bodily fluids. It details specific disinfection principles based on the transmission routes of infectious diseases (e.g., digestive, respiratory, and contact transmission). The standard specifies the required chemical disinfectants, such as chlorine-based compounds and peracetic acid, for treating contaminated environments, utensils, excreta, and corpses. It also includes specialized procedures for handling prion-contaminated materials (referencing Annex B). Additionally, the standard defines the terminal disinfection working procedures (Annex A), requiring personnel to follow strict protocols for personal protection, area zoning, and sequential disinfection (e.g., outside-to-inside, top-to-bottom). Proper documentation and record-keeping for all disinfection activities are also mandated.
Testing methods
The standard outlines disinfection effect evaluation methods (Annex C) to verify pathogen eradication. Testing involves sampling from object surfaces, air, and sewage using specific microbial culture techniques. Key evaluations include checking for the absence of target pathogens and calculating the elimination rate of natural bacteria. It also references specific microbiological testing standards for indicator organisms like Salmonella and Shigella.
FAQs
What products and facilities are regulated under GB 19193-2015?
The standard applies to the disinfection of infectious foci for all types of infectious diseases. It is mandatory for public health institutions, disease control centers, and medical facilities managing infectious disease outbreaks, excluding the handling of prion-contaminated materials which is treated as informative.
Are there any significant updates from the previous version of GB 19193-2015?
Compared to the 2003 version, this update modifies the hygienic requirements for concurrent and terminal disinfection, and revises the disinfection principles for various infectious disease foci. It also introduces new informative annexes regarding prion-contaminated material handling and disinfection work record forms.
How does GB 19193-2015 differ from international disinfection standards?
GB 19193-2015 establishes the overarching principles and procedures for disinfection in infectious disease foci in China. It frequently references specific national standards for testing and evaluation, such as GB 15982 for hospital hygiene and GB 18466 for medical sewage, rather than duplicating those international ISO testing protocols.
