Assistant Laboratory Animal Technician (ALAT) Practice Exam

What is one of the primary functions of proper ventilation in animal housing?

1. Enhancing social interactions

2. Thermoregulation

3. Preventing the build-up of harmful gases

4. Improving animal health

The correct answer is: Preventing the build-up of harmful gases

Proper ventilation in animal housing plays a crucial role in preventing the build-up of harmful gases, which is essential for maintaining a safe and healthy environment for the animals. Without adequate ventilation, gases like ammonia from urine and carbon dioxide from respiration can accumulate, potentially leading to respiratory issues, stress, and other health complications for the animals. Ensuring that there is adequate airflow helps to dilute these gases, remove odors, and maintain air quality within the facility, thereby supporting the animals' well-being and productivity. While ventilating can contribute to thermoregulation and may tangentially improve animal health, the primary and most immediate function of ventilation is to manage and prevent harmful gas accumulation. This is a fundamental aspect of providing a suitable housing environment for laboratory animals, illustrating the importance of proper design and maintenance in laboratory animal facilities.
