The FDA has defined three types of liquid chemical germicides for processing medical devices, and these germicides are regulated as auxiliary devices (FDA 1977 Policy Manual):ĭisinfectants used in the laboratory include those recommended by equipment manufacturers and a broad-spectrum product, typically an intermediate-level disinfectant (i.e., a product with a mycobacteriology claim). The list of selected EPA-registered disinfectants are available on the EPA website. The more commonly used public health antimicrobial products are described in the Glossary (e.g., sporicides, disinfectants, and sanitizers). 3 The laboratory is responsible for selecting an appropriate EPA-registered product and using it according to the manufacturer’s instructions on the product label. RegulationsĪntimicrobial pesticides (e.g., disinfectants) are classified as pesticides and are regulated by both the United States Environmental Protection Agency (EPA) under the authority of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) 1,2 and the United States Food and Drug Administration (FDA), Center for Devices and Radiologic Health by the Food Quality Protection Act (FQPA).

General approaches are emphasized instead of detailed protocols and methods. ![]() Accidents involving infectious aerosols have been a source of contamination within the laboratory setting and may impact the method chosen for decontamination. One must remember that aerosol-generating procedures should be conducted in containment. Regulatory oversight, terminology, factors necessary for environmentally-mediated transmission of infection (e.g., aerosol generation, contact, indirect contact), methods for sterilization and disinfection, and the levels of antimicrobial activity associated with liquid chemical disinfectants are reviewed in this appendix. This chapter describes basic strategies for decontamination or disinfection of environmental surfaces, items, and areas in laboratories and other practices to mitigate the possibility of transmission of infectious agents to laboratory workers, the public, and the environment.
