Assistant Laboratory Animal Technician (ALAT) Practice Exam

Why should dirty cages and soiled equipment be taken to the cage wash area instead of being cleaned in the animal room?

1. To save time and reduce labor

2. To maintain a sterile environment

3. Airborne dust and microorganisms can contaminate the animal room

4. Chemicals in the cleaning supplies can harm the animals

The correct answer is: Airborne dust and microorganisms can contaminate the animal room

Cleaning dirty cages and soiled equipment in the cage wash area is essential primarily to protect the integrity of the animal room environment. When dirty cages are cleaned in the animal room, airborne dust and microorganisms can be disturbed and released into the air, potentially contaminating the space where the animals reside. Maintaining a clean and uncontaminated environment is crucial for the health and well-being of laboratory animals, as they can be sensitive to pathogens that might be stirred up during the cleaning process. Moving these cleaning activities to a designated cage wash area helps contain contaminants and protects the animals from exposure to potentially harmful agents. Additionally, this practice minimizes the risk of cross-contamination between different animal housing areas. This systematic approach ensures a safer environment for both the animals and the personnel working with them.
