Assistant Laboratory Animal Technician (ALAT) Practice Exam

Which two features of a cage dumping station are designed to protect the technician during cage changing?

1. The air circulating fan and HEPA filter

2. The sliding door and locking mechanism

3. The transparent walls and padded surfaces

4. The drainage system and sterilization lights

The correct answer is: The air circulating fan and HEPA filter

The correct choice highlights the importance of maintaining a clean and safe environment for technicians during cage changing, as well as protecting their health. The air circulating fan and HEPA filter are significant features in a cage dumping station because they work together to minimize airborne contaminants that could be harmful to the technician. The air circulating fan helps to create airflow that aids in the removal of particles and pathogens from the area. Simultaneously, the HEPA filter ensures that at least 99.97% of particles that are 0.3 microns or larger are trapped, effectively reducing exposure to potential allergens, pathogens, or debris that may be present during the cage changing process. This combination of features contributes to a safer working environment for the technician by improving air quality and reducing the risk of respiratory issues or infections. Other options, while they may provide useful functions within the context of animal care and cage maintenance, do not specifically relate to protecting the technician during the process of changing cages in the same way that proper air circulation and filtration do.
