Which type of equipment requires complete sanitation between uses?

Restraint equipment requires complete sanitation between uses because it comes into direct contact with animals and can act as a vector for disease transmission. This equipment, such as restraint devices and cages, can harbor pathogens, bacteria, or other contaminants from one animal to the next. Thorough cleaning and disinfecting are necessary to prevent cross-contamination during research or handling sessions.

While non-research tools, other laboratory equipment, and animal housing units also need proper sanitation, the level of sanitation required and the potential for disease transmission are particularly critical with restraint equipment due to its close interaction with multiple animals. This ensures not only the health and safety of the animals but also the integrity of the research being conducted. Proper sanitation protocols are essential in maintaining a facility's biosecurity and minimizing the risk of infectious disease spread in laboratory animal environments.
