What is legal definition of ventilation?

In legal contexts, "ventilation" refers to the process of providing fresh air to an enclosed space to ensure adequate air quality and circulation, often related to health and safety regulations. It may involve the installation of systems or structures that facilitate airflow in buildings, particularly in workplaces, to prevent the buildup of harmful pollutants. Compliance with ventilation standards is often mandated by local building codes and occupational safety laws to protect the well-being of occupants.
